Pensoft Celebrates International Tea Day with Fascinating Discoveries in Camellia

Camellia species are famous for their tea properties, providing the leaf buds and young branches used to manufacture black, green, and oolong tea.

At Pensoft Publishers, we are proud to support the open-access dissemination of botanical knowledge through our journal PhytoKeys. On International Tea Day, we invite you to spill the tea on the captivating world of the genus Camellia. While most people recognise these plants as the source of their morning brew, the genus is incredibly diverse and economically significant.

Camellia species are famous for their tea properties, providing the leaf buds and young branches used to manufacture black, green, and oolong tea. Beyond the teapot, these evergreen shrubs and trees are valued for their oil-producing seeds and their stunning ornamental flowers in horticulture. Despite their global fame, we are still discovering new members of this family, often in the remote forests of East and Southeast Asia.

One of the most dramatic stories recently published in PhytoKeys concerns Camellia hekouensis, a tree native to Hekou in Yunnan, China. For a time, the botanical community feared the species was lost forever after the last known living tree died at the end of 2024 due to bark destruction.

However, a dedicated effort by the staff of the Dawei Mountain National Nature Reserve saved the species from the brink. They successfully protected 11 wild trees and propagated 32 others ex-situ. This species is particularly interesting because its chemical profile challenged previous scientific claims. While earlier researchers suggested it lacked certain purine alkaloids, new analysis shows the leaves actually contain 1.18 mg/g of theobromine.

Further research in Yunnan has revealed another unique relative of the common tea plant named Camellia yangii. Discovered in the forests of Malipo County, this species is a true member of the tea section, yet it stands out for being remarkably hairy. It bears a red or purplish red terminal bud that is densely pubescent, making it a rare and visually striking germplasm resource.

Lead researcher Dongwei Zhao of Central South University of Forestry and Technology, Changsha, found that while most Camellia species have five sepals, Camellia yangii typically bears only three. It also follows its own schedule, flowering about a month later than other tea plants in the vicinity. This late flowering phase is a natural barrier that prevents it from hybridising with other species, keeping its genetic line distinct. With fewer than ten individuals known in the wild, its discovery is a call to action for urgent protection.

Botanical science sometimes involves correcting the records of the past, as seen in the reinstatement of Camellia angustifolia. This species from Guangxi, China, was originally described in 1981 but was later dismissed as a mere synonym of another variety in 1992.

Recent field investigations proved that this was a mistake. Researchers from the Guangxi Research Institute of Tea Science discovered that the original type specimen was actually a misidentified bellflower from a completely different family. Once the correct specimens were examined, the differences became clear – unlike its shrubby relatives that grow only a few meters tall, Camellia angustifolia is a majestic tree that can reach heights of 20 meters.

Our journey through recent tea-related discoveries concludes in the striking Danxia landscape of Guangdong Province. Here, researchers identified Camellia shangshii, a new species endemic to the red sandstone formations of Danxiashan Mountain. This species bears smaller leaves and flowers than its closest relatives. One of its most defining features is that its white petals are fused together at the base for several millimeters.

This tree notably thrives in a unique microclimate where specialised soils and environmental contrasts drive the evolution of distinct species. It is named in honour of Dr. Shangshi Wu, a scientist who pioneered the study of these geological landscapes.

As we celebrate International Tea Day, these discoveries remind us that our knowledge of the natural world is still growing. Every new species found and every historical error improves our understanding of the biological heritage of our favorite beverages. At Pensoft, we will never stop be-leafing in the power of new species to inspire conservation and science!

New “Happy-Face” Spider Species Discovered in the Indian Himalayas

For over a century, this cheerful-looking creature was thought to be a unique resident of the Hawaiian Islands.

Vibrant, tiny, and sporting a bright red grin on its back, the Happy-Face spider is one of the most famous and recognisable arachnids in the world. For over a century, this cheerful-looking creature was thought to be a unique resident of the Hawaiian Islands, a biological curiosity found nowhere else on Earth.

When researchers from the Forest Research Institute and the Regional Museum of Natural History discovered a new species of spider with the same unmistakable smile in the montane mountains of Uttarakhand, India, they knew exactly what to call it: Theridion himalayana, the Himalayan Happy-Face Spider.

“The discovery was accidental because our survey was [originally] on ants. But my co-author [Ashirwad Tripathy] kept sending me spiders from high altitude regions for identification.

So, one fine day, when he shared this image from the underside of a Daphniphyllum leaf, I froze in shock because I had seen the Hawaiian spider during my master’s programme itself, and I knew instantly we had a jackpot because of its striking resemblance.

I asked him to send all morphs that he found, and that led to the discovery in the next few months, from October 2023 onwards.”
Devi Priyadarshini, Regional Museum of Natural History, Bhubaneswar

Priyadarshini added that she was always interested in exploring high-altitude spiders because the landscape and vegetation are so different there than in the plains:

“This almost came across as a gateway to look at other polymorphic species from this region.”

Ashirwad also said that we could find more variations in the species if the surveys could be done extensively.

The species name, himalayana, serves as a tribute to the mountain range where the spider was found at elevations of over 2,000 meters above sea level.

“The name Himalayana was decided as the species name because we both wanted to pay our respects to the mighty Himalaya mountain ranges, which have been standing tall not just guarding our country but also holding a plethora of biodiversity within them.

Since this spider was the first polymorphic from this region, we decided to make it an ode to the amazing mountain ranges.”
Ashirwad Tripathy, Forest Research Institute, Dehradun

The research, published in the open-access journal Evolutionary Systematics, identified 32 different colour variations, or “morphs”, of the species collected from three locations in Uttarakhand: Makku, Tala, and Mandal. DNA analysis revealed a genetic variation of approximately 8.5% from the Hawaiian happy-face spider, confirming it as a separate lineage that evolved independently in Asia.

While the smiling patterns are striking, their exact purpose remains a mystery.

“The reason behind the expression of polymorphism is also very complex and unique.

These patterns definitely help them survive better in the wild, which is understood prima facie, but why do they resort to such patterns on their back, and what functional role in their life cycle does it exactly serve is yet to be deciphered. This is definitely indicative of a deeper genetic mystery.”
Priyadarshini

Ashirwad also mentioned that the spider species was surrounded by critters which had similar colour patterns on their body.

The study additionally noted that these spiders are frequently found on ginger plants (Hedychium species), mirroring the behaviour of their Hawaiian cousins. Since ginger is not native to Hawaii, the researchers are intrigued by the evolutionary connection.

“How did the spiders choose an invasive species and ginger exactly? If T. himalayana is an elder cousin of T. grallator, although discovered 125 years later!

Although this sounds like a tall claim now, it will be our further scope of work to establish any missing links, if at all, through Hedychium sps.”

Celebrating Deep Day with Incredible Deep-Sea Research

Protecting the deep sea, the largest and least explored habitat on Earth, requires collaborative effort.

May 7th marks Deep Day, a global day of awareness and action dedicated to the deep sea. Founded by the Deep Sea Conservation Coalition, it aims to raise awareness of the deep sea’s immense ecological importance and call for its protection against threats like deep-sea mining and destructive fishing.

To celebrate the wonders of our oceans and raise awareness of the incredible biodiversity of the deep sea, we at Pensoft Publishers would like to highlight some of the remarkable marine studies that have recently been published in our scientific journals.

A Global Collaboration to Uncover Deep-Sea Amphipods

Demonstrating the power of global teamwork, an international group of experts recently discovered 24 new deep-sea amphipod species in the central Pacific Ocean’s Clarion-Clipperton Zone (CCZ). Researchers from institutions worldwide, including the University of Lodz and the National Oceanography Centre, came together for a coordinated taxonomy workshop to achieve this. Their work revealed a completely new evolutionary branch with the discovery of a new superfamily, Mirabestioidea.

Crucially, their findings form part of the International Seabed Authority’s Sustainable Seabed Knowledge Initiative (SSKI) and its ‘One Thousand Reasons’ project, which aims to formally describe 1,000 new species by the end of the decade.

Highlighting the importance of this joint effort, Dr. Anna Jażdżewska from the University of Lodz shared:

This was a truly collaborative process that allowed us to achieve the ambitious goal of describing more than 20 species new to science within a year – something that would not have been possible if each of us worked independently. The team’s findings provide information that is crucial for future conservation and policy decisions.

Rather than using traditional trawls that can damage fragile organisms, the team utilized crewed submersibles and free-fall baited landers. Explaining the value of this non-destructive method, the research team noted:

This combination enabled us to build the most comprehensive visual baseline yet for abyssal and hadal megafauna in the Northwest Pacific to date.

They added that the study aims to establish a foundation for the future, emphasizing that:

More than anything, the hadal zone remains one of Earth’s least-explored and most intriguing frontiers.

The Internet Names a New Deep-Sea Chiton

Finally, highlighting a unique way the public can engage with science and taxonomy, a recently found deep-sea chiton was named by the internet after science YouTuber Ze Frank featured it in an episode of his “True Facts” series. Originally discovered in 2024 within the Izu-Ogasawara Trench at a depth of 5,500 meters, this new species belongs to the genus Ferreiraella, a rare and specialized group of mollusks that live exclusively on sunken wood in the deep sea.

From over 8,000 suggestions submitted across social media, the research team selected the name Ferreiraella populi. The epithet populi is a Latin singular noun in the genitive case meaning “of the people”.

Prof. Dr. Julia Sigwart, co-chair of the Senckenberg Ocean Species Alliance (SOSA), emphasized the broader significance of this public discovery:

Ferreiraella populi exemplifies the overwhelming biodiversity of the oceans, the vast majority of which remains unexplored. Many species go extinct before we even know they exist – this is especially true for marine invertebrates.

New ‘Ecclesiastical’ Moth named after Pope Leo XIV

Described as Pyralis papaleonei, the finding serves as a powerful call for biodiversity conservation, inspired by a biblical reference.

Distinguished by its striking colors and a name that carries the weight of a high ecclesiastical office, a new species of moth has been discovered in the rugged terrain of Greece. When researchers from the Tyrolean State Museum, the Finnish Museum of Natural History and the Bavarian State Collection of Zoology identified this unique insect in the White Mountains of Crete, they chose a name that reflects both its noble appearance and a message of environmental hope: Pyralis papaleonei – derived from “Papa Leone” (Pope Leo).

The discovery, published in the open-access journal Nota Lepidopterologica on 28 April 2026, highlights that even among such conspicuous European moths, overlooked species remain to be discovered. The new species is currently only known from the White Mountains (Lefka Ori) in the western part of Crete, where it appears to be an endemic treasure of the island.

Striking purple forewings

The so-called Pope Leo Moth has a wingspan of around two centimeters, placing it among the medium-sized representatives of its group. Its most distinctive features are its purple forewings with an orange-golden patch and prominent white bands. The moths were recorded at artificial light sources and appear to be mainly active in June. So far, little is known about the biology and lifestyle of the new species. It was distinguished from related species based on classical morphological characteristics – such as wing pattern, coloration, and genital morphology – as well as genetic fingerprinting. Molecular analyses revealed a divergence of around six percent from its closest relative, clearly indicating that it represents a distinct species.

A tradition of remarkable species names

Butterflies and moths are often named after physical characteristics, geographic origins, or in honor of distinguished individuals. Within the genus Pyralis, however, a particular tradition can be observed: as early as 1775, Austrian naturalists Michael Denis and Ignaz Schiffermüller described the first species of the group as Pyralis regalis (“royal”), inspired by its splendid coloration. This was followed by sonorous names such as Pyralis princeps and Pyralis cardinalis, also referring to the remarkable beauty of these moths.

All these species belong to the diverse superfamily Pyraloidea, which comprises around 16,000 described species worldwide and represents one of the largest groups among micro-moths.

Taxonomy as the “first profession” of humankind

The naming of living organisms also has a cultural-historical dimension: in the Old Testament (Genesis 2), Adam is firstly tasked with naming all animals. In this sense, taxonomy – the science of classifying, naming, and organising organisms – can be regarded as one of humanity’s earliest endeavors.

For study leader Peter Huemer of the Tyrolean State Museum Ferdinandeum, naming a species is therefore more than a formal scientific act: it also serves as a symbolic appeal to the head of the Catholic Church, Pope Leo XIV, to highlight humanity’s central responsibility in safeguarding creation. This is particularly fitting as butterflies and moths are regarded in Christianity as symbols of resurrection, transformation (metamorphosis), and the immortal soul.

Only a fraction of global biodiversity documented

Peter Huemer, former head of the Natural Science Collections at the Tyrolean State Museums and now a volunteer researcher, explains:

“We are facing a global biodiversity crisis, yet only a fraction of the world’s species has been scientifically documented. Effective conservation of biodiversity requires that species are first recognised, described, and named.”

Around 700 new moth species are described each year, primarily in the tropics. However, fundamental research in Europe is far from complete: in the Alps alone, approximately 200 previously unknown species have been identified in recent decades.

With their internationally significant scientific collections, the Tyrolean State Museums make an important contribution to this work. The discovery of the Pope Leo Moth, Pyralis papaleonei, highlights how much remains to be discovered even in well-studied regions of Europe—and underscores the urgent need to protect sensitive habitats.

A New Species of Fly Found on the Lesser Brown Horseshoe Bat

A bizarre new species of parasitic fly sheds its wings and legs to live permanently embedded in a bat’s ear.

Imagine a fly that decides flying is overrated. Instead, it finds a bat, sheds its wings, drops its legs, and burrows into the host’s skin for the rest of its days. This is the reality of the genus Ascodipteron, a group of highly specialised bat flies that challenge our basic definition of what an insect looks like.

In a recent study published in the open-access journal ZooKeys, researchers led by Haoran Sun of Beijing Forestry University have identified a new member of this strange family in the Yunnan Province of China. It brings some fascinating, if slightly macabre, biological quirks to the table.

The newly discovered species has been named Ascodipteron euryale and was found on the lesser brown horseshoe bat, known scientifically as Rhinolophus stheno. This discovery is particularly significant because it represents the first time a fly from this genus has been documented on this specific species of bat. These flies often show an incredibly narrow host range and a strict preference for where they live on the bat’s body. In the case of Ascodipteron euryale, they prefer the base of the bat’s ear, the tragus, or the ear pinna.

*Ascodipteron* *euryale* sp. nov. and its host *Rhinolophus* *stheno*. (Image credit: Haoran Sun et al.).

The life of a female Ascodipteron fly is especially interesting. After a very brief period of seeking out a host, the female undergoes a radical transformation into what scientists call a neosome. It essentially becomes an endoparasite, embedded so deeply in the bat’s tissue that often only its posterior end is visible, protruding slightly so it can breathe and release larvae. This particular species was discovered in Xianren Cave, located in the Simao District of Pu’er City, at an elevation of 2428 meters above sea level.

*Ascodipteron* *euryale* sp. nov., ex. R. *stheno* – the top two images display the whole neosome. (Image credit: Haoran Sun et al.).

What makes Ascodipteron euryale stand out from its 17 known cousins? The most defining physical trait is the shape of its mesosternum, a part of its underside, which features gently rounded lobes on the back corners. Further, unlike many related flies that are covered in soft skin and easily removed, these neosomes were found encased in a fibrous cyst or shell – this is a reaction from the host bat’s own immune system, creating a protective barrier that makes the parasite very difficult to extract.

*Ascodipteron* *euryale* sp. nov., ex. R. *stheno*, head and thorax. (Image credit: Haoran Sun et al.).

The naming of the species is a clever nod to Greek mythology. The host bat, Rhinolophus stheno, shares a name with Stheno, one of the three Gorgon sisters who could turn onlookers to stone. The researchers decided to name the new fly euryale after Euryale, another of the Gorgon sisters. In the myths, these two sisters were immortal, and the authors note that this name choice reflects their hope that the deep-rooted biological association between this specific bat and its resident fly continues long into the future.

This research adds a sixth species of Ascodipteron to the records in China, emphasising the impressive biodiversity hidden within the country’s cave systems. It also raises new questions for future study, particularly regarding why some of these flies trigger the formation of fibrous shells while others do not. For now, Ascodipteron euryale remains a testament to the strange and highly specific ways life finds a niche (even if that niche is the inside of a bat’s ear)!

Inside the Hidden World of Spider-Attacking Fungi

Newly discovered groups of “zombie” fungi have been found to mummify spiders and adapt their physical forms.

Deep within the humid leaf litter of China and the dense canopies of Brazil’s Atlantic Forest, a silent ambush unfolds.

While we often think of spiders as the ultimate predators of the undergrowth, they have an arch-nemesis: araneopathogenic fungi. These “zombie” fungi are capable of parasitising spiders by hijacking their bodies and consuming them from the inside out.

Two studies published in the open-access peer-reviewed scientific journals MycoKeys and IMA Fungus, respectively, offer insight into this macabre world of spider assassins.

In Southeast Asia, researchers led by Chen-xin Chang of the Guizhou University of Traditional Chinese Medicine have identified three new species of Gibellula fungi in China and Laos, which erupt from spiders in branch-like structures: Gibellula pseudopigmentosa, Gibellula pseudosolita, and Gibellula sinensis. These species are distinguished from one another by their slight variations in sexual reproductive structures and morphology. The below figure displays morphological plates, showing the three fungi species at both a macroscopic and microscopic level – notice their unique conidial heads and spore arrangements, coloured in blue.

To identify new species of spider-pathogenic fungi, the research group conducted field surveys in the forest leaf of China and Laos, where they collected specimens for detailed laboratory study. A combination of traditional microscopy and modern DNA sequencing rendered the discovery possible. The fungi’s sighting in Laos is particularly significant because it provides the first formal record of the Gibellula genus in the region.

This study – published in MycoKeys – therefore serves to fill a major distributional gap in Southeast Asia, as well as expand our understanding of the morphological diversity within this group of spider-pathogenic fungi.

Meanwhile, in Brazil, a study led by Joao Paulo Machado De Araújo of the University of Copenhagen and the Royal Botanic Gardens of Kew, published in IMA Fungus, described a new species of Purpureocillium fungus belonging to the Purpureocillium atypicola group: Purpureocillium atlanticum. This fungus specifically targets trapdoor spiders inhabiting burrows on the forest floor, where it mummifies the host in white mycelia and subsequently emerges from its cephalothorax in the form of a purple fruiting body.

The discovery was notably featured in The Guardian, where it was placed alongside other unusual botanical and fungal discoveries compiled by the Royal Botanic Gardens, Kew.

Purpureocillium atypicola was originally recorded in Japan by Yasuda (1894), and was thought to be a single species found all over the world for over a century. The discovery of the Purpureocillium atlanticum in Brazil is significant because it finally confirms that Purpureocillium atypicola is actually a global complex of many unique species.

To identify this new fungus, De Araújo’s research group used taxogenomics, a method which entailed bringing portable DNA sequencing gear directly into the Brazilian rainforest. By analysing the genetic code of the fungus and its environment immediately in the field, they were able to identify the specimen within just four days as opposed to waiting months for traditional lab results.

Both of these studies highlight the impressive diversity of spider-pathogenic fungi across distinct global environments. They additionally reveal the different evolutionary strategies of their respective species – while Purpureocillium atlanticum has adapted to infect underground trapdoor spiders by producing purple stalks to escape burrows, the Gibellula species represent the most diverse genus of spider parasites, found primarily in forest debris.

As researchers continue to map these complex ecological networks, it becomes clear that preserving threatened biomes, including the Atlantic Forest and the jungles of Southeast Asia, is critical to expanding our knowledge in fungal taxonomy.

A Philosopher’s Serpent: New Grass-Green Pitviper Discovered in China’s Giant Panda National Park

The species name honours the philosopher known as Laozi, whose teachings emphasise the balance between humanity and the natural world.

The misty forests of the Giant Panda National Park in western Sichuan have long been a focus for biodiversity conservation. While the park is synonymous with its namesake bear, recent research has highlighted a different kind of resident. A team of scientists from the Chengdu Institute of Biology and other regional institutions recently identified a new species of pitviper that had been overlooked for decades. The results are published in the open-access journal Zoosystematics and Evolution.

Named Trimeresurus lii, or the Huaxi Green Pitviper, the snake was previously confused with the more common bamboo pitviper. Through a combination of genetic sequencing and detailed physical analysis, researchers determined that these populations represent a distinct lineage. The species name honours Li Er, the philosopher known as Laozi, whose teachings emphasise the balance between humanity and the natural world.

Visually, the Huaxi Green Pitviper is defined by its vibrant grass-green body and distinct eye colors that range from amber to orange-yellow. There are clear physical differences between the sexes. Males feature a tricolor stripe of red and white along their sides, while females possess a simpler yellow stripe. One of the technical features that helped researchers distinguish this snake from its relatives is its smooth head scales, a trait not found in similar species within the region.

The discovery took place in the West China Rain Zone, specifically around Mt. Emei and Xiling Snow Mountain. This area is a known biodiversity hotspot, yet many of its smaller or less charismatic species remain understudied. The identification of Trimeresurus lii as the 58th species in its genus serves as a reminder that even well-documented regions still hold biological secrets.

This find underscores the broader value of the Giant Panda National Park. By protecting large swaths of habitat for flagship species, the park inadvertently preserves a complex ecosystem of specialised reptiles and amphibians. Documenting these animals is a necessary step toward understanding the full scope of life within China’s protected wilderness.

The Emerald Forest: The middle Magdalena river Valley in Colombia, a biodiversity treasure hidden until recently

Lowland tropical rainforests, especially in South America, harbour the world’s most diverse flora – including a wide array of neotropical trees.

Guest Blog Post by M. Alejandra Jaramillo

The Mountains

In May 2022, we went on our first expedition to Serranía de Las Quinchas. To reach the Serranía, we turned west in the municipality of Chiquinquirá (known by its beautiful Cathedral, dated 1796), Boyacá department.

Little by little, we left behind the farmland and paved roads, reaching the deep green forest patches a few miles after the town of Otanche (one of the main sites of Emerald commerce).

Leydi Galvis and her parents, Don Lucindo y Doña Edilsa, greeted us with kind smiles and hot coffee, and we subsequently set up the camp to prepare for the next day’s expedition. We spent three days walking up and down the slopes, finding beautiful plants wherever we looked.

Accompanying our group of students from Universidad Militar was Dayro Rodriguez, a young botanist with an incredible eye for plants and a perceptive photographer. It was like visiting the Chocó Region – very humid, green, and diverse!

In our first expedition, we collected most of our plants, including a new species of peltate leaves belong to pepper family (Piperaceae); “caipe” (Orphanodendron gradiflorum C. Cast. & G.P. Lewis), and Romeroa verticillata Dugand.

Interestingly, our Piper quinchasense M. A. Jaram., has now been spotted in several localities in the middle Magdalena Valley. The enigmatic legume Orphanodendron, meanwhile, derives its generic name from its classification within a subfamily of the Fabaceae. However, “caipe” is a locally common tree used for timber.

Romeroa, on the other hand, is a monospecific genus of trees in the Bignoniaceae with unifoliolate leaves. It is a Colombian endemic taxon, known exclusively in wet forests, such as the Las Quinchas region, located in the Boyacá, Cundinamarca, and Santander departments. The genus has been collected only a few times after its description 70 years ago.

Thus, the flora at Las Quinchas is an exciting combination of species with affinities to the Andes, Chocó Region, and the North West Amazon, with many endemics that make the area a deep, green paradise.

Subsequent expeditions to the site have consistently yielded discoveries of new and rare plant species. These efforts are supported by a close collaboration with Gerardo Aymard, an expert botanist whose unrivaled ability to review collections and identify new taxa is essential to our work.

Gerardo’s botanical expertise has allowed him to identify two new species to science: Grias lucindoae Aymard & M. A. Jaram. (Lecythidaceae) and Schlegelia longirachis Aymard & M. A. Jaram. (Schlegeliaceae). Both rare genera are often missed by collectors or remain untouched in Herbaria.

The Lowlands

In 2024, we had the opportunity to visit the lowlands in the same region. A team of faculty and students from Universidad Militar Nueva Granada visited Reserva “El Paujil”.

Lizette Sierra, Paula Lara, and Luisa Suarez came across a tree species with a unique flower that, no doubt, turned out to be a new taxon. Again, by the joint efforts of the young and inquisitive Andres F. Majin-Ladino, and the expert eye of Gerardo Aymard, we decided it was a rare Sapotaceae – this is one of those families for which indeterminate specimens pile up in herbaria around the world, as botanists just do not find flowers or the courage to identify species.

We consulted the world expert in Sapotaceae, Terrance D. Pennington (The Royal Botanical Gardens, Kew), who was puzzled by the flowers he did not recall. Andres F. Majin-Ladino, with support from Fundación Proaves, visited the locality several times to collect additional samples. We conducted molecular sequence analyses, and the four of us henceforth described a new species of Sarcaulus, S. paujilensis M. A. Jaram. & T. D. Penn, now published in the open-access journal PhytoKeys.

The Bigger Picture

It is noteworthy that the Serranía de las Quinchas is at the heart of Emerald’s business in Colombia. Mining has been the fundamental activity in the region for very long time, not only of emeralds but also coal. We ought to thank the locals for conserving the remaining beautiful forests. More exploration is needed in the region to uncover its diversity, and efforts should be made to provide alternative economic activities for the community if we want to curb deforestation.

Currently, Las Quinchas region represents a complex and fragile spot of biodiversity that remains largely uncharted, even after centuries of exploration. Humans have long modified the environment and examples of overexploitation and associated species eradication are well-documented.

Forest ecosystems, such as the Magdalena River valley, are the most important global repository of terrestrial biodiversity, with more than half of tree species at risk of extinction. Quantifying the current global forest biodiversity is therefore an essential step towards mitigating global biodiversity loss and restoring biodiversity in severely affected areas.

Tree species diversity underpins forest ecosystem functionality and services, as well as the diversity of assemblages of flora, fauna, and microbes. Therefore, characterising and describing tree species diversity (i.e., Sarcaulus paujilensis), as well as its spatial patterns, is also crucial for safeguarding global ecosystem functioning, food, water, energy security, and our well-being.

We are confident that many new plant species of the common families (i.e., Burseraceae, Lecythidaceae, Leguminosae, Meliaceae) of these wet forests will reveal themselves as we visit the locality and walk along the ridges with our eyes open.

Key to our discoveries is our passion for exploring the forest. Indeed, we have young students like Andrés Majin, and young botanists like Dayro Rodriguez on our side. Don Lucindo is equally attentive to let us know about flowering and fruiting periods and rare plants to examine. The contribution of young botanists and local experts has been key to our discoveries!

Remarkable Bat Discoveries from the ZooKeys Archives

These discoveries, ranging from a species rediscovered after a century to new regional records, emphasise the impressive diversity of bats.

Bats are nocturnal mammals that are critical to healthy ecosystems around the globe; they act as pollinators, seed dispersers, and natural pest controllers. In honour of Bat Appreciation Day (17 April), we are highlighting some of the most interesting bats published in our open-access journal ZooKeys.

The following discoveries, ranging from a species rediscovered after a century to new regional records, emphasise the remarkable diversity of bats and the ongoing efforts of researchers to understand and protect them.

The Strange Big-eared Brown Bat (Histiotus alienus)

For over a hundred years, the strange big-eared brown bat was known only from a single specimen collected in Uruguay in 1916. This elusive species remained unseen by the scientific community for a century, leading to significant uncertainty regarding its biology and true distribution.

However, a study led by Brazilian researchers documents the rediscovery of this bat in the Palmas Grasslands of southern Brazil, providing the first confirmed record for the country. This finding significantly expands the known range of the species and offers researchers the first opportunity to provide a detailed redescription.

Histiotus alienus is distinguished by its large and oval ears that are connected by a low skin fold. Its fur is a deep, dark brown on the back, while the underside is slightly paler. The rediscovery occurred in a unique landscape characterised by high-altitude grasslands and Araucaria forests, a habitat that is increasingly threatened by human activity.

ZooKeys 1174: 273-287. https://doi.org/10.3897/zookeys.1174.108553

The Flat-skulled Woolly Bat (Kerivoula depressa)

The world of bat taxonomy is constantly shifting as researchers use new tools to differentiate species that look nearly identical. Another study formally documents the first records of the flat-skulled woolly bat, Kerivoula depressa, in China.

Previously, many woolly bats in the region were grouped together under other names, but detailed morphological and genetic analysis confirmed that K. depressa is a distinct part of the Chinese fauna, specifically in Guangdong and Yunnan provinces.

The defining feature of this species is its notably flattened braincase. This physical trait is an evolutionary adaptation that allows the bat to roost in very narrow spaces, such as the hollow internodes of bamboo. The bat has woolly fur that ranges from buff brown to dark brown, and it is relatively small in size.

The presence of this specialist bat in China highlights the complexity of tropical forest ecosystems and the need for further taxonomic work to correctly identify and conserve local biodiversity.

The Lesser False Vampire Bat (Megaderma spasma)

Islands often host a high number of unique species, yet their mammalian populations are frequently understudied. A comprehensive survey on Ko Pha-ngan, an island off the coast of Thailand, identifies the lesser false vampire bat, Megaderma spasma, as a new record for the island.

This species is a member of a group known for their distinctive appearance and predatory habits. While its name might sound ominous, it does not feed on blood; instead, it preys on insects and occasionally small vertebrates.

The lesser false vampire bat is easily recognised by its exceptionally large ears that are joined at the base and the absence of a visible external tail. During the survey, researchers found this species in a variety of environments, including national park forests, disturbed forest fragments, and areas with human settlements.

The discovery of M. spasma and eighteen other new records on Ko Pha-ngan demonstrates the importance of conducting biodiversity surveys in tourist-heavy regions to inform better conservation policies.

The Grey-bellied Dwarf Dog-faced Bat (Molossops griseiventer)

Some species remain hidden until scientists take a closer look at existing museum collections and genetic data. For years, the grey-bellied dwarf dog-faced bat was considered a synonym of the more common Molossops temminckii. However, a recent revision has revalidated Molossops griseiventer as a separate species.

This grey-bellied dwarf dog-faced bat can be identified by its characteristic greyish ventral fur and specific cranial proportions. Beyond its appearance, the revalidation of this species has major implications for its protection. Unlike its more widespread relatives, M. griseiventer is restricted to the inter-Andean valleys of Colombia, a region heavily impacted by agricultural development.

Because it is now recognised as an endangered species, conservationists can advocate for specific protections for its remaining habitat. This case proves that understanding the true diversity of bats is a prerequisite for effective conservation.

ZooKeys 1180: 237-256. https://doi.org/10.3897/zookeys.1180.109091

The stories of these four species remind us that our understanding of biodiversity is always evolving. Through continued exploration and open-access publishing, we can better appreciate and protect the bats that share our planet.

Meet the Crevice Weaver: A Newly Discovered Urban Spider from Colombia

The Pikelinia floydmuraria, a new addition to the South American Pikelinia population, was observed in Colombia’s department of Tolima and is now described in the journal Zoosystematics and Evolution.

A team of researchers from institutions across South America have expanded scholarly knowledge of the Pikelinia spider genus, with their recent discovery of a new crevice weaver species: Pikelinia floydmuraria.

The new species name is a creative tribute to the legendary rock band Pink Floyd, while simultaneously referencing the spider’s specific habitat. “Muraria,” derived from the Latin word for “wall”, reflects the species’ tendency to reside in the walls of buildings, though indeed also alludes to the iconic Pink Floyd album, The Wall.

These findings are described in greater detail in the open-access journal Zoosystematics and Evolution (ZSE) and serve as a particularly important contribution to the wider study of synanthropic spiders – species that have adapted to human-created environments. Despite the ecological importance of these spiders in Colombia, research into their biology and nutritional ecology has received little attention. The discovery of the Pikelinia floydmuraria, alongside observations of additional populations in neighbouring Colombian departments, holds the potential to remedy this problem.

The species establishment

The first regional review of the genus Pikelinia was established in 1946 by the Brazilian zoologist Mello-Leitão. For decades, the genus remained obscure, with species often misidentified or “lumped” into the type genus Filistata, most commonly found in the Mediterranean region.

In 2022, however, a major study redefined Pikelinia as part of a distinct South American spider group. Pikelinia floydmuraria is the most recent addition to the genus and provides considerable insight into the dietary composition of these crevice weavers.

Skilled hunters

These spiders are skilled hunters, primarily feeding on insects including flies, beetles and ants. Remarkably, they are capable of taking down prey up to six times their own size and often build their webs near streetlights to catch insects attracted to the glow. The above figure provides a visual representation of the spider’s predatory behaviour in urban habitats, demonstrating its ability to prey on insects larger than itself.By keeping these insect populations under control, crevice weavers thus maintain a healthier balance in the Colombian urban environment.

The research team behind this discovery, led by Osvaldo Villarreal and Leonardo Delgado-Santa, note that Pikelinia floydmuraria only measure about 3 to 4 millimetres in length. One of their most unique internal features is found in the females, which contain reproductive organs comprising long and slender tubes that are shaped like the letter “S”. In urban environments, they can be found tucked in the cracks and crevices of building walls, with observed concentrations reaching between 20 and 30 spiders in a single square metre.

The researchers further observed that Pikelinia floydmuraria is a very close relative of another species called Pikelinia fasciata, which lives in the Galapagos Islands. Despite being separated by the Pacific Ocean and Andes mountain range, the two look almost exactly alike, leaving scientists to wonder: how did such similar spiders end up so far apart? It remains a mystery as to whether these traits reflect shared ancestry or similar ecological adaptations.

Nonetheless, the two can be differentiated by the appearance of their legs, with the Colombian spider displaying solid-colours, and the Galapagos featuring darker rings by contrast. The Galapagos female spiders additionally have shorter and straighter reproductive organs in comparison to the Colombian female.

Further research needed

In order to better determine whether Pikelinia floydmuraria is a unique species native to Colombia, the South American researchers suggest the implementation of DNA barcoding in future studies. This will provide genetic evidence that could help map the evolutionary history of Pikelinia floydmuraria. A DNA-based dietary analysis, meanwhile, would quantify the extent to which these spiders operate as natural urban pest regulators.

Whether they are just “another web in the wall” or a relative from the Galapagos, the discovery of Pikelinia floydmuraria represents a significant advancement in our understanding of South American spider taxonomy. By identifying this new Colombian species and providing the first-ever detailed anatomical description for its relative, Pikelinia fasciata, researchers have expanded scientific knowledge of the Pikelinia genus.

Pikelinia floydmuraria may be small and “comfortably numb” to the bustle of the city, but their impact on maintaining a healthy urban ecosystem is anything but quiet.
