More petals often equals more appeal for flower lovers. Double and semi-double blooms are popular among gardeners for their lush, ornate appearance. But, while they are common in cultivated varieties, they are exceptionally rare in the wild.
So, when researchers from China discovered a new species with naturally occurring semi-double flowers, they knew they had found something special.
What are single, semi-double, and double flowers?
To appreciate this discovery, it’s helpful to understand what makes a flower “single,” “double,” or “semi-double.”
Left-to-right: single, semi-double, and double flowers in Rosaceae.
Single flowers have the typical number of petals for their species, arranged in a single row. This number is usually five in the rose family (Rosaceae). Single-flowered plants are by far the most common wild species.
Double flowers have been bred or mutated to have many extra petals, often replacing stamens, giving them a full, layered look. While they are popular for their aesthetic value, double flowers are often poor (or entirely useless) for pollinators.
Semi-double flowers are an intermediate form. They have more than the typical number of petals (often in two whorls), but fewer than fully double flowers, usually around 10–12 petals. Semi-double flowers are rare in the wild and – like double flowers – are almost always cultivated.
Double and semi-double blooms are prized for their beauty and prolonged flowering, but are typically only seen in cultivated ornamentals, not in wild populations.
Rubus semiplenus
Discovered in 2022 during a botanical expedition in Hunan Province’s Nanyue Hengshan National Nature Reserve, Rubus semiplenus is a rare example of a wild species with semi-double flowers. Scientists from Yunnan University and local botanical institutions confirmed it as a new species and published their findings in the open-access journal PhytoKeys.
Rubussemiplenus.
Unlike most of its Rubus relatives, R. semiplenus grows as a small herb or dwarf subshrub rather than a woody shrub. The bramble’s leaves are simple and nearly round, which is also unusual for the genus, and its flowers have 10–12 white petals arranged in two whorls, clearly distinguishing it from related species like Rubus hirsutus, which has the typical five-petaled, single flowers.
The floral trait seen in R. semiplenus is exceptionally rare in wild Rubus species. While some cultivated varieties and a few exceptions (like Rubus rosifolius var. coronarius) show similar traits, spontaneous semi-double flowers are almost unheard of in the wild. The discovery is also taxonomically significant. Genetic and morphological analyses place R. semiplenus within the section Rosaefolii, but it is the only known member of that group with both simple leaves and semi-double flowers, which may provide insight into floral evolution and development within the Rubus genus.

One year ago, Pensoft embarked on an exciting new journey to connect with the vibrant scientific community in China by launching our official Weibo account. This initiative was designed to foster closer ties with Chinese researchers, academics, and science enthusiasts—helping to broaden the reach of scientific knowledge and promote international collaboration.
Highlights from Our First Year
Over the past 12 months, we’ve shared a wide range of articles, research highlights, and updates from our diverse portfolio of open-access journals. Here are some of the most memorable moments from our first year:
Our most viewed video featured the discovery of three new species ofNautilus—the iconic deep-sea mollusks. Published in ZooKeys, the study described species from the Coral Sea and South Pacific. The video captivated marine biology fans and drew thousands of views. Videos are a powerful way to share science, and we encourage researchers to include video materials whenever possible!
Our most viral post introduced the newly described supergiant Bathynomus vaderi—a massive deep-sea isopod discovered off the coast of Vietnam. Its name, vaderi, was inspired by the creature’s head, which bears a striking resemblance to the iconic helmet worn by Darth Vader in Star Wars.
Another popular post highlighted new mimetid spider species (Araneae, Mimetidae) discovered in Guizhou Province, published in Zoosystematics and Evolution. The study shed light on the region’s rich spider biodiversity and sparked strong engagement from our Chinese followers. It seems that spiders are a consistent fan favorite, with arachnid discoveries regularly going viral on our Weibo!

This trend continued with our most popular longread, which told the story of Otacilia khezu sp. nov., a newly discovered cave-dwelling spider from Guangxi, China, published in the Biodiversity Data Journal. What truly captured readers’ imaginations—beyond the biological discovery—was the name itself. The spider was named after the Khezu, a wyvern from the popular video game Monster Hunter, known for its blindness and eerie appearance. Just like its namesake, Otacilia khezu completely lacks eyes — a striking adaptation to life in the dark.
As we celebrate this milestone, we’re filled with excitement for what lies ahead. We look forward to continuing to share cutting-edge science, uncovering new discoveries, and building stronger connections with our Chinese readers and partners.
Thank you to everyone who has followed, shared, and supported us over the past year. Your engagement has made this journey meaningful and rewarding.
Researchers have discovered three new Pleurothallis orchid species in the cloud forests of Costa Rica and Panama. The new species utilise an unusual method of asexual reproduction known as prolification.

Found in the cool, misty highlands of the Talamanca range at elevations between 1400 and 2550 metres, the newly discovered species, Pleurothallis matrisilvae, Pleurothallis pridgeoniana and Pleurothallis winkelianaare described in the open-access journal PhytoKeys.

Prolificating plants produce miniature plantlets directly from their flowering stems, allowing them to bypass seed production.
Whilst prolification is rarely a fixed feature within this group of orchids, it becomes common under stressful environmental conditions. The ability may be advantageous in the challenging conditions of cloud forests, but remains underexplored scientifically. Methods of asexual reproduction might also be important when pollinators are scarce.

The new species have each adapted to exhibit prolification in different ways, such as forming long chains or bushy growths. These adaptations helped researchers identify them as distinct species, despite their initial visual similarities with other plants.
With close to 1700 species currently recorded, a third of which not known from anywhere else in the world, Costa Rica is a well-known orchid biodiversity hotspot. The discovery of these orchids displays the Talamanca range’s significance as a rich and largely unexplored area.

With these additions, Costa Rica now boasts 67 recognised species of Pleurothallis, though researchers believe many more await formal identification. Such abundance highlights the importance of conserving these unique ecosystems.
Thanks to Costa Rica’s robust system of protected areas (SINAC), local institutions such as Lankester Botanical Garden of the University of Costa Rica are able to uncover and describe floristic novelties in an effort to study and conserve the country’s unique biodiversity.

Bermuda’s Walsingham cave system harbors a wide diversity of cave-dwelling animals not found anywhere else in the world; now, one more joins their ranks as researchers of the University of Cambridge, the Bermuda Institute of Ocean Sciences and Senckenberg am Meer German Centre for Marine Biodiversity Research have discovered a new copepod species.

Copepods are some of the most diverse of all crustaceans, found everywhere from freshwater ponds to the open ocean. These tiny organisms are some of the most abundant animals in the marine plankton, and an essential component of food webs worldwide. However, their huge diversity remains rather poorly known, particularly in challenging environments like subterranean caves.
The new Bermudian copepod, Tetragoniceps bermudensis, was first collected in 2016 by Sahar Khodami, Pedro Martinez Arbizu, and Leocadio Blanco-Bercial from the Bermuda Institute of Ocean Sciences and the Senckenberg am Meer German Centre for Marine Biodiversity Research, who ventured into Roadside Cave through a narrow passageway in Bermuda’s ancient limestone bedrock. However, it was only when researchers analysed it in detail, in 2024, that T. bermudensis was confirmed to be an entirely new species. Like other members of Bermuda’s cave fauna, Tetragoniceps bermudensis – named after the country where it was discovered – might represent an ancient, early-diverging member of its evolutionary lineage, the research team say. Together with other ancient crustaceans inhabiting the island’s caverns, it persisted in a secluded, delicate underground ecosystem relatively free from competitors and predators.

“The new species of copepod crustacean, Tetragoniceps bermudensis, is the first of its genus from Bermuda, as well as the first known cave-dwelling species of the genus anywhere in the world and only the second within its family, Tetragonicipitidae,” says lead author Giovanni Mussini of the University of Cambridge’s Department of Earth Sciences. “This finding from Roadside Cave adds to the great diversity of endemic crustaceans (and other cave fauna) found in the island’s network of limestone caves.”
The team during the sampling expedition to Roadside Cave in 2016.
The team only found one female egg-bearing individual at Roadside Cave, a small cavern in Bermuda. It is hard to estimate just how rare the new species is based on a single specimen, but the finding “suggests a correspondingly limited area and a probable endemic status, consistent with the high degree of endemism typical of Bermuda’s cave-dwelling fauna,” the researchers write in their paper in the journal ZooKeys.
Views of Roadside cave.
Roadside Cave, where the new species was found, may face threats from “urban development, vandalism, dumping, littering and pollution, and sediment disturbance due to unlawful access by humans and domesticated animals,” which makes protecting this small creature all the more urgent. The researchers call for formal protection of the cave and for robust enforcement of existing measures to protect its precious fauna.
“The discovery of this species highlights that there remains a cryptic diversity of cave-dwelling species still to be discovered even in a densely populated island like Bermuda, whose hidden, underground biodiversity is all too often overlooked,” Mussini says in conclusion.

In the heart of Canada’s Rocky Mountains, an unassuming yet remarkable butterfly has been quietly flying under our scientific radar for years. With a wingspan of an inch to an inch and a half, and wings that are brown on top and greyish brown with black spots below, this population was long thought to belong to the Half-moon Hairstreak (Satyrium semiluna). However, the isolated hairstreak butterflies of Blakiston Fan in Waterton Lakes National Park, Alberta, have now been recognized as a distinct species: Satyrium curiosolus, or the Curiously Isolated Hairstreak.
Satyrium curiosolus.
A recent study by an international collaborative team, published in ZooKeys, uncovered the unique evolutionary history of this population. The results were striking: Satyrium curiosolus has been completely isolated from its closest relatives for quite a while—possibly up to 40,000 years— becoming more and more genetically and ecologically unique along the way.
The science behind the discovery
“Our whole-genome sequencing of S. curiosolus revealed strikingly low genetic diversity and exceptionally high levels of historical inbreeding compared to the geographically nearest S. semiluna populations in British Columbia and Montana, more than 400 km distant,” says co-first author Zac MacDonald, a La Kretz postdoctoral researcher at University of California Los Angeles Institute of the Environment and Sustainability. Despite its small population size, genetic data suggest that S. curiosolus has likely maintained itself as a stable, independent lineage for tens of thousands of years. “Like the Channel Island Fox, S. curiosolus may have purged some of its harmful recessive genetic variation through a long, gradual history of inbreeding, allowing it to persist as a small and completely isolated population today,” MacDonald adds.
Satyrium curiosolus.
Satyrium curiosolus is found in a distinct habitat unlike any other population of S. semiluna that we know of. While its relatives thrive in sagebrush steppe, S. curiosolus occupies a single alluvial fan that is more accurately described as prairie-grassland, where it associates with different plants and ant species. Satyriumcuriosolus relies exclusively on silvery lupine (Lupinus argenteus) for larval development, a plant not known to be used by S. semiluna populations in British Columbia.

“Furthermore, we recently discovered that S. curiosolus larvae have mutualistic relationships with a particular species of ant (Lasius ponderosae), which has not been observed in other S. semiluna populations,” says James Glasier of the Wilder Institute/Calgary Zoo, who was also part of the study. Satyrium curiosolus caterpillars provide the Lasius ants with a sugary excretion called honeydew to eat, while in return the ants protect the caterpillar from parasites and predators. Caterpillars also retreat into ant galleries when disturbed, or when it gets too hot out, and adult females have been observed laying eggs right near the entrances to Lasius colonies under Silvery Lupines.
Why it matters
The recognition of S. curiosolus as a species has important implications, highlighting its unique evolutionary trajectory and emphasizing an urgent need for tailored conservation strategies.
The discovery of S. curiosolus is a powerful demonstration of how genomics is revolutionizing taxonomy and conservation.
Julian Dupuis, Assistant Professor in the Department of Entomology at University of Kentucky
Satyriumcuriosolus faces a somewhat unique challenge: its long-term isolation has resulted in very low genetic diversity, which means that the species has a reduced potential to adapt to changing climatic conditions. While conservationists often consider genetic rescue—introducing individuals from related populations to boost genetic diversity—as a solution to low genetic diversity, the distinctiveness of S. curiosolus raises concerns about potential outbreeding depression when mixed with S. semiluna. It is likely that the two species are not even reproductively compatible, meaning S. curiosolus may be on its own. Conservation efforts must now consider new solutions, such as establishing additional S. curiosolus populations, to help this butterfly persist as climate change threatens ecological change at Blakiston Fan.
A case study in genomics and conservation

“The discovery of S. curiosolus is a powerful demonstration of how genomics is revolutionizing taxonomy and conservation,” remarked co-first author Julian Dupuis, an Assistant Professor in the Department of Entomology at University of Kentucky. “While traditional taxonomic methods often rely on morphology alone, our study underscores the importance of integrating genomic and ecological data to uncover hidden diversity. With the rise of genomic tools, previously unrecognized species like S. curiosolus are being discovered, highlighting the need for conservation strategies that account for cryptic biodiversity.” Dupuis adds.
Collaboration in conservation
The Curiously Isolated Hairstreak reminds us that even the smallest and most overlooked species can hold extraordinary scientific and conservation significance.
“Our studies on S. curiosolus and S. semiluna highlight the importance of collaboration between academic scientists, nonprofit organizations, and conservation managers. All of this work was made possible through partnerships between academic researchers, Parks Canada, and the Wilder Institute/Calgary Zoo. By combining expertise in genomics, field ecology, and conservation management, we were able to produce findings that not only reshape our understanding of biodiversity but also provide actionable insights for species protection. Moving forward, these interdisciplinary collaborations will be critical for tackling complex conservation challenges and ensuring the long-term survival of species like S. curiosolus,” added MacDonald.
The future of Satyrium curiosolus
Title: S. curiosolus larvae being attended to by Lasius ponderosae ants.
Recognizing S. curiosolus as a distinct species is just the beginning, the researchers say. Future research should explore its evolution and interactions with other species like host plants and ants. Additionally, long-term monitoring by Parks Canada and the Wilder Institute/Calgary Zoo will be essential to assess how this species copes with climate change and what conservation actions are appropriate. “This is a wonderful example of how such monitoring can connect diverse approaches and impactful answers to a simple question like ‘that’s odd – why is it there?’”, says anchor author Felix Sperling, a professor at the University of Alberta and curator of the U of A’s Strickland Museum of Entomology.
“For now, the Curiously Isolated Hairstreak reminds us that even the smallest and most overlooked species can hold extraordinary scientific and conservation significance,” the researchers say in conclusion.

China’s Guizhou Province has long been known for its remarkable biodiversity, but a recent study in Zoosystematics and Evolutionhas shed light on some of its creepier, lesser-known inhabitants: pirate spiders.
What is a pirate spider?
The name ‘pirate spiders’ refers to species belonging to the family Mimetidae. Also known (misleadingly) as cannibal spiders, they earned their name because of their araneophagic (spider-eating) nature.

These eight-legged predators don’t spin webs to catch prey; instead, they infiltrate the webs of other spiders and mimic the vibrations of prey or potential mates, then ambush the unsuspecting hosts when they come to investigate.
A recent research paper by Zhang et al. offers the most comprehensive survey to date of the pirate spider genus Mimetus in Central Guizhou, including two new species, bringing the provincial total to eight and giving Guizhou the highest Mimetus diversity in China.

China’s new species
Mimetus guiyang
Mimetusguiyang.
Discovered in Guiyang City, this species is known only from females collected via pitfall traps. Its most distinctive feature is the presence of large bubble-shaped ossified hair bases on the abdomen, a rarity among known Mimetus species. Its genital morphology and body patterns make it easily distinguishable from close relatives.
Mimetus lanmeiae
Mimetuslanmeiae.
Also found in Guiyang, this species was observed perched on a spider web, likely in the act of mimicry. Its unique palpal structures and small body size (~2.14 mm) distinguish it from other known Mimetus species. The name of the species honours the mother of the specimen collector. Hopefully this was meant as a compliment.
Other findings
New records: The researchers recorded two previously known species (M. caudatus and M. sinicus) for the first time in Guizhou, expanding their known range.
Rediscovery and redescription:M. caudatus, previously known only from male specimens, now has its female described in detail.
Molecular insights: DNA barcoding (COI gene sequencing) was used to support species identification and match males and females – a critical step for accurate taxonomy, especially given the subtle differences between males and females in Mimetus.

Species belonging to the genus Thismia are some of the strangest and most magical-looking in the plant kingdom, which has earned them the nickname ‘fairy lanterns.’
No exception to the rule, a newly discovered Thismia species from eastern Peninsular Malaysia looks like something that belongs in a fantasy world.
Take a look below.
Thismia aliasii.
Standing just 11 cm tall, Thismia aliasii is an easy-to-miss and Critically Endangered new species described in the open-access journal PhytoKeys.
The genus Thismia consists of plants that are mycoheterotrophic, meaning they do not photosynthesise and instead rely entirely on fungi for their nutrition. The unusual flowers seen on Thismia species facilitate specialised pollination mechanisms involving small insects such as fungus gnats.
Thismia aliasii was first documented by co-author Mohamad Alias Shakri in 2019 during a field expedition in Terengganu’s Chemerong Forest Eco Park, not far from a hiking path.

“The discovery of Thismia aliasii is very interesting as it was found in a mountainous region known for its natural beauty. The discovery was made on the edge of a popular mountaineering trail, but, remarkably, the species was first recognised by Alias.
“It was not easy to obtain specimens for further study as its habitat is on the mountain and COVID time delayed search efforts. Fortunately, targeted field work to find this plant was successful with the support of NAGAO.”

Thismia aliasii is provisionally classified as Critically Endangered (CR) under the IUCN Red List criteria, with only five individuals observed across multiple surveys. The primary threats to its survival stem from habitat degradation due to increasing hiking activities in the region.
This discovery adds to Terengganu’s reputation as a hotspot for Thismia diversity, being home to 13 species of the genus, including six endemics.

“We have not only revived Francis Walker’s species Topiris candidella, from 1863, but also expanded our understanding of an entire group of small white moths.”
A moth neglected by experts for a century is found to have been collected by Alfred Russel Wallace 169 years ago
Cutting-edge techniques allowed scientists to show the moth as belonging to a genus comprising 14 species, 11 of which are new to science
One of the new species has been named after Greta Thunberg
Alfred Russel Wallace
Scientists at the Natural History Museum (NHM), London, have discovered that a long-overlooked moth specimen in the Museum’s collection was in fact collected by explorer and naturalist, Alfred Russel Wallace, in 1855. This was at the same time as he was formulating his own revolutionary ideas on the origins of species which he would go on to share with Charles Darwin.
The small white moth, Topiris candidella, was described in 1863 by Francis Walker but was dismissed in 1927 by leading entomologist Edward Meyrick as “better neglected” having suffered substantial damage due to historic storing practices. The moth has remained overlooked for nearly a century, until now.
Using a cutting-edge DNA sequencing method, NHM scientists extracted genetic material from a single fragment of one of the specimen’s remaining legs and connected it to a group of moths found throughout South East Asia.
The scientists were able to prove that rather than being a single neglected species, Topiris is in fact a genus of 14 species, including 11 species which are new to science and described today in the paper published in ZooKeys.
One of these species is named Topiris thunbergella, in honour of Greta Thunberg and her work in raising awareness of the environmental pressures on the native forests of South East Asia.
A new to science species of land snail was discovered by a group of citizen scientists working together with scientists…
Dr David Lees, Senior Curator for Microlepidoptera at the Natural History Museum, adds, “This discovery highlights the incredible potential of modern DNA analysis to reveal the evolutionary history of species, even from fragmented and long-forgotten specimens.
“By applying this innovative sequencing technique, we have not only revived Francis Walker’s species Topiris candidella, from 1863, but also expanded our understanding of an entire group of small white moths.”
During their research, David and fellow moth expert, Mark Sterling, found that a hidden label under the pin of the broken moth bore the handwritten letters “SAR”, a clue that this moth had been collected by Alfred Russel Wallace as part of over a thousand moths he collected at Rajah Brooke’s Forest retreat.

Topiris thunbergella
Topiris salva
This was in December 1855, just months before he published his ‘Sarawak Law’ paper, which eventually led to a joint reading (at Darwin’s request) of their theories of evolution through natural selection.
Beyond the scientific breakthrough, the study has wider conservation implications. Of the 24 species reviewed in their paper, only three have been recorded since 2000, highlighting the urgent need for biodiversity monitoring in this region.
Mark Sterling added, “The 80 million specimens currently held in the Natural History Museum’s collections continue to be a critical resource for understanding biodiversity and assessing the effects of environmental change.”

When Rebecca Tarvin was a graduate student studying toxins in the skins of poisonous frogs, she and her colleague Mileidy Betancourth-Cundar collected a frog in Colombia that they suspected was a new species. It differed in coloration from a similar Colombian frog in the genus Epipedobates and had a different mating call.

In 2022, eight years later and a newly appointed assistant professor of integrative biology at the University of California, Berkeley, Tarvin met up with Colombian biologists to collect more of these frogs and confirm a new species. Such “holotype specimens” are necessary to document a new species for posterity. Collecting specimens and identifying new species also helps scientists track the impact of environmental changes and understand the evolutionary origin of traits such as skin toxins, which may one day have medical uses.

Collecting the frogs was easy; they seem to thrive along roadsides and in semiurban areas. But what to name the species? A Colombian colleague played for the team a tape of local marimba-based music called bambuco, and one style, called bambuco viejo, or currulao, stood out. The name Epipedobates currulao seemed appropriate, and with this month’s publication of a paper describing the new species in the journal ZooKeys, it’s now official.

“We ended up going with currulao because we liked how it brought in the human perspective,” Tarvin said. “The frog is part of the sound landscape; when they call, it’s part of the background noise in the region. Similarly, currulao is more than just a genre of music. It’s also the cultural practices around the music, the gathering, dancing and the relationship-forming aspects of the experience.”
A performance by Cantadoras del Pacifico at the 2009 Smithsonian Folklife Festival. Currulao, which combines marimbas and drums, is popular in black communities along Colombia’s Pacific coast.
Tarvin is still investigating the toxins produced by frogs in the genus Epipedobates, which is small, containing about eight species, but is the most recently evolved group of poisonous frogs in South America. By comparing the genetics of these frogs with other poison frog groups, she hopes to understand how their chemical defense technique evolved. Most poisonous animals are brightly colored to advertise their unpalatability, such as the Monarch butterfly’s bright orange color and the gaudy orange, black and blue of poison dart frogs. But Epipedobates frogs are more subtly colored, if not downright drab. Perhaps, she said, bright coloration evolves after the frogs develop their toxic defenses.

Epipedobates acquired its chemical defenses more recently than any other group in the poison frog family and shows the largest range in color and defense, Tavin said, but they’re also interesting because of how they acquire their toxicity.
“What’s unique about poison frogs, specifically, is that they sequester toxins from their food, so it’s an entirely different kind of defense that requires an entirely different physiology, compared to venom-producing animals, like snakes and bees,” she said. “Poison frogs eat arthropods that have small amounts of chemicals that can be either toxic or distasteful. And then they accumulate those to levels that become relevant for their own predators.”
Tarvin offers one piece of advice: Because they’re covered in poisons, don’t lick your fingers after picking one up.

This story was originally published by UC Berkeley. It is republished here with permission.
Discovered in the Andean cloud forests of northern Peru, a new species in the blazing star family (Loasaceae) has reinforced the vital role of citizen science in plant research.
An international research team collected, identified and documented the rare plant after seeing photographs uploaded by Peruvian naturalist, Carlos Pérez Peña, on the citizen science platform iNaturalist. Assigning the species the name Nasa katjae, they published the discovery in the open-access journal PhytoKeys.
Nasa katjae has striking scarlet-red flowers adapted for hummingbird pollination and is endemic to a single forest near Colasay in the Cajamarca region of Peru, not far from a populated area. Due to its extremely narrow range, it is likely particularly vulnerable to the threat of habitat loss.
The discovery highlights the importance of protecting the remaining pristine habitats in the Amotape-Huancabamba Zone, a biodiversity hotspot home to many rare and isolated species. The team behind the study emphasise that, without immediate conservation efforts, these ecologically fragile regions could be lost to agricultural expansion and climate change before they are fully understood.
Lead author Dr Tilo Henning of the Leibniz Centre for Agricultural Landscape Research remarked on the significance of the find: “If we have overlooked this striking plant, think about what we have missed in more unobtrusive organismal groups such as mosses, fungi and insects.”
“Discovering such a conspicuous flowering plant in a forest directly adjacent to a larger human settlement signifies that we have not even begun to fully map the biodiversity of some regions. We urgently need more taxonomists and funding to meaningfully tackle this.”
While some areas in northern Peru have recently received formal protection, the forest fragment in which Nasa katjae is found remains unprotected. The authors of the study urge decision makers to take action to safeguard these habitats before it is too late.
The discovery of Nasa katjae displays the power of digital tools and citizen science in biodiversity research. Platforms like iNaturalist prove invaluable in detecting and documenting rare species, complementing traditional fieldwork and accelerating new discoveries.
