While monitoring of cryptic and elusive tiny creatures, such as pygmy seahorses that measure only 13 to 27 mm, might be too costly and time-consuming for research teams and institutions, the underwater activity might be proving of particular interest to photography and diving enthusiasts.
At least, this is what comes across from the recent reports of five miniature species identified from Taiwanese waters by local citizen scientists and passed along via Facebook and Instagram. Amongst the findings, there are two species that had never before been reported from the country, including last year’s media sensation: the ‘Japan pig’, considered to only be found in the “Land of the Rising Sun”. The study, conducted by the team Mr. Joseph Heard, Drs Jeng-Ping Chen and Colin Wen from Tunghai University and Taiwan Ocean Research Institute, is published in ZooKeys, the very same open-access journal that saw the description of the species in 2018.
The scientists note that pygmy seahorses are largely unknown species and even basic information regarding their habitats is largely inconsistent and based on unofficial reports. As monitoring of marine wildlife can be expensive and time-consuming, especially regarding its small and cryptic representatives, the researchers decided to use “Phone a Friend” lifeline. Scuba divers and underwater photographers were approached on social media to help investigate pygmy seahorse diversity in Taiwan.
Their call resulted in 259 social media items, including 75 photos of 78 miniature creatures from their natural habitats at five different locations. Identified as five separate species, their discovery ranks Taiwan as one of the world’s biodiversity hotspots for pygmy seahorse, given that there are only seven species of pygmy seahorses out there.

Four of those were found at Green Island alone, a small volcanic Pacific island, measuring only 15 km2.
Pygmy seahorse specimen collection from Taiwan for future examination is still undergoing.

A new issue of the scholarly, open-access and peer-reviewed journal PhytoKeys focuses on the Chinese biodiversity hotspots and their substantial role in understanding the country’s unique flora. The special issue embarks on a treasure hunt into China’s biodiversity hotspots, including the descriptions of 23 species previously unknown to science and new insights into the ecological diversity of ferns based on their DNA sequences.
In China, biodiversity-rich landscapes vary from the dry Northwest region, through the surrounded by massive mountain ranges of the Qinghai-Tibet Plateau, to the tropical and subtropical southern China. The combination of remote and hard to reach mountain areas and diverse microclimates promises high levels of endemism.
“With extended collaboration among Chinese scientists and coordination of networks on plant conservation and taxonomy across China, we synthesize a special issue entitled “Revealing the plant diversity in China’s biodiversity hotspots”, to present the latest findings by Chinese botanists, and to update knowledge of the flora for China and adjacent countries”, explained De-Zhu Li, professor of botany at Kunming Institute of Botany (KIB), Chinese Academy of Sciences (CAS), in the editorial.
Among the newly described species, four new members of the African violet family were found from a subtropical forest in Yunnan province in southern China, discovered by researchers from Xishuangbanna Tropical Botanical Garden, CAS and their collaborators. Half of them were found only from a sole population and require further botanical examinations to deploy the conservation priorities, remark the scientists.
In another paper, scientists Yun-Feng Huang and Li-Na Dong and Wei-Bin Xu, representatives of Guangxi Institute of Botany, revealed the discovery of a new species from the primrose family. Found nowhere outside the limestone areas in Liucheng county (Guangxi, China), this rare plant species is currently facing serious threats of extinction because of the fragility and sensitivity of its habitat to the environmental changes associated with the rapid economic development of China.

The special issue features the description of additional two orchid species, discovered in Motuo, located at the Himalayan border between China, Myanmar and India. The region is well known for its vertical vegetation system, varying from tropical forest to permanent glaciers. Ji-Dong Ya and Cheng Liu from the KIB and Xiao-Hua Jin from the Institute of Botany, CAS underline that the difficult access to the area allows the thriving and diversification of plants.

A novel approach relying on a short sequence of mitochondrial DNA in conjunction with a lateral image of the holotype specimen was proposed to greatly accelerate species identification and description, especially when it comes to hyperdiverse taxa, such as parasitic wasps.
At today’s rate, it could take another two millennia for science to document all currently existing species of multicellular life
Two hundred and sixty-one years ago, Linnaeus formalized binomial nomenclature and the modern system of naming organisms. Since the time of his first publication, taxonomists have managed to describe 1.8 million of the estimated 8 to 25 million extant species of multicellular life, somewhere between 7% and 22%. At this rate, the task of treating all species would be accomplished sometime before the year 4,000. In an age of alarming environmental crises, where taking measures for the preservation of our planet’s ecosystems through efficient knowledge is becoming increasingly urgent, humanity cannot afford such dawdling.
“Clearly something needs to change to accelerate this rate, and in this publication we propose a novel approach that employs only a short sequence of mitochondrial DNA in conjunction with a lateral image of the holotype specimen,”
Description rate of parasitic wasps species (superfamily Ichneumonoidea). Data from Taxapad (Yu et al. 2016).
In standardized practices, it is required that experts conduct plenty of time- and labor-consuming analyses, in order to provide thorough descriptions of both the morphology and genetics of individual species, as well as a long list of characteristic features found to differentiate each from any previously known ones. However, the scientists argue, at this stage, it is impossible to pinpoint distinct morphological characters setting apart all currently known species from the numerous ones not yet encountered. To make matters worse, finding human and financial resources for performing this kind of detailed research is increasingly problematic.
This holds especially true when it comes to hyperdiverse groups, such as ichneumonoid parasitoid wasps: a group of tiny insects believed to comprise up to 1,000,000 species, of which only 44,000 were recognised as valid, according to 2016 data. In their role of parasitoids, these wasps have a key impact on ecosystem stability and diversity. Additionally, many species parasitise the larvae of commercially important pests, so understanding their diversity could help resolve essential issues in agriculture.
Meanwhile, providing a specific species-unique snippet of DNA alongside an image of the specimen used for the description of the species (i.e. holotype) could significantly accelerate the process. By providing a name for a species through a formal description, researchers would allow for their successors to easily build on their discoveries and eventually reach crucial scientific conclusions.
“If this style were to be adopted by a large portion of the taxonomic community, the mission of documenting Earth’s multicellular life could be accomplished in a few generations, provided these organisms are still here,”
say the authors of the study.
To exemplify their revolutionary approach, the scientists use their paper to also describe a total of 18 new species of wasps in two genera (Zelomorpha and Hemichoma) known from Área de Conservación Guanacaste, Costa Rica. Currently, the team works on the treatment of related species, which still comprise only a portion of the hundreds of thousands that remain unnamed.

A remarkable bioluminescent click beetle was discovered in the subtropical evergreen broadleaf forests in southwest China. Having prompted the description of a brand new subfamily, the species is the very first bioluminescent click beetle known from the continent.
A remarkable bioluminescent click beetle was discovered in the subtropical evergreen broadleaf forests in southwest China. Scientists Mr. Wen-Xuan Bi, Dr. Jin-Wu He, Dr. Xue-Yan Li, all affiliated with the Chinese Academy of Sciences (Kunming), Mr. Chang-Chin Chen of Tianjin New Wei San Industrial Company, Ltd. (Tianjing, China) and Dr. Robin Kundrata of Palacký University (Olomouc, Czech Republic) published their findings in the open-access journal ZooKeys.
Even though the family of click beetles (Elateridae) contain approximately 10,000 species worldwide, it is only about 200 species able to emit light, and they inhabit Latin America and Oceania. Interestingly, the position of the luminous organs varies amongst the different click beetle lineages. In some, they are found on the foremost of the three thoracic segments of the body (prothorax), in others – on both the prothorax and the abdomen, and in few – only on the abdomen.
Luminescent behavior of Sinopyrophorus schimmeli gen. et sp. nov. Video by Mr Wen-Xuan Bi.
“In 2017, during an expedition to the western Yunnan in China, we discovered a dusk-active bioluminescent click beetle with a single luminous organ on the abdomen, ” recalls lead scientist Mr. Wen-Xuan Bi.
Since no bioluminescent click beetle had previously been recorded in Asia, the team conducted simultaneous morphological and molecular analyses in order to clarify the identity of the new species and figure out its relationship to other representatives of its group.
Co-author Dr. Xue-Yan Li explains:
“The morphological investigation in combination with the molecular analysis based on 16 genes showed that our taxon is not only a new species in a new genus, but that it also represents a completely new subfamily of click beetles. We chose the name Sinopyrophorus for the new genus, and the new subfamily is called Sinopyrophorinae.”
In conclusion, the discovery of the new species sheds new light on the geographic distribution and evolution of luminescent click beetles. The authors agree that as a representative of a unique lineage, which is only distantly related to the already known bioluminescent click beetles, the new insect group may serve as a new model in the research of bioluminescence within the whole order of beetles.

The team described two new species from the Ecuadorian Andes
University of Central Florida student Veronica Urgiles has helped describe two new frog species discovered in Ecuador, and she named one of them after one of her professors.
UCF student Veronica Urgiles named one of the new frog species in honor of Biology Professor Pedro Quintana-Ascencio for his years of dedication to conservation efforts in Ecuador. Photo by UCF, Karen Norum.
She explains:
“Frogs are by far my favorite. So, getting to describe and name two of them is terrific. I have been looking at these frogs for years now, so going over the whole process of observing them in their habitats and then analyzing them and comparing them under the microscope, to finally naming them is a long, but very satisfying journey.”
Urgiles, a 2017 Fulbright scholar and the lead author, said she chose to attend UCF for its integration of genetics and genomics in biodiversity research and the emphasis on real-world application. She works with Assistant Professor Anna Savage who specializes in species diversity based on molecular analyses.
“One of the things that I found most interesting about these guys is that they don’t have metamorphosis like a regular frog, but instead they develop entirely inside eggs that adult females deposit in the ground,” Urgiles said. “They really don’t need water bodies for their development. Both of the new frog species inhabit high elevation ecosystems in the mountain range over 8,000 feet, so even though we are right there in the equator, it’s very cold and windy most of the year.”
The team of researchers has been studying frogs in Ecuador the past few years. In 2017, Urgiles found the first new species and named it Pristimantis quintanai, after one of her biology professors — Pedro Quintana-Ascencio. She and Savage found the second species — Pristimantis cajanuma — in 2018. Both were found in the Paramo and montane forest of the southern Ecuadorean Andes.

The frogs are tiny, measuring 0.8 inch. Pristimantis quintanai females are brown and black and Pristimantis cajanuma are green and black, both easily blending into the foliage. They have a distinct call that is sharp and continuous, sounding like tik-tik-tik-tik.
Urgiles examined DNA samples collected by the international team back in Savage’s lab at UCF, generated genetic sequences, and constructed the phylogenetic analysis. Other team members also worked the morphological diagnosis and comparisons with other frogs and an acoustic analysis of the frogs’ calls.
Anna Savage, whose expertise includes describing species diversity based on molecular analyses, says:
“In these analyses, we use all of the genetic similarities and differences we find to build phylogenetic trees, and when we find that a ‘branch’ on the ‘tree’ has strong support and contains all of the individuals that share the same morphological characteristics, then we have good evidence to describe it as a new species. We used this method, along with vocalization and location data, to conclude that the two species we describe are distinct from any other species that have ever been characterized.”
The work is critical because of the vast diversity that has yet to be discovered in the tropical Andes of South America, Urgiles adds. In 2018, 13 new species of frogs were documented in the tropical Andes of Ecuador and so far in 2019 five new frogs have been documented.
There are potentially thousands of new plants and animals in the area that may hold the key to other discoveries. It’s important to know what is there, to better understand the threats to habitat loss and disease so conservation methods can be established to protect the resources.

Described in 1981, the genus Biswamoyopterus is regarded as the most mysterious and rarest amongst all flying squirrels. It comprises two large (1.4-1.8 kg) species endemic to southern Asia: the Namdapha flying squirrel (India) and the Laotian giant flying squirrel (Lao PDR). Each is only known from a single specimen discovered in 1981 and 2013, respectively.
Recently, in 2018, a specimen identifiable as Biswamoyopterus was unexpectedly found in the collections of the Kunming Institute of Zoology (KIZ), Chinese Academy of Sciences by in-house expert Quan Li. It had been collected from Mount Gaoligong in Yunnan Province, Southwest China.

However, a closer look at the specimen from KIZ made it clear that the squirrel exhibited a colouration, as well as skull and teeth anatomy, distinct from any of the previously known species in the genus.

Subsequently, joined by his colleagues from China (Xuelong Jiang, Xueyou Li, Fei Li, Ming Jiang, Wei Zhao and Wenyu Song) and Stephen Jackson from Australia, the team of Quan Li conducted a new field survey. Thus, they successfully obtained another specimen and, additionally, recorded observations of two other flying squirrels. As a result, they included a third member to the enigmatic genus: Biswamoyopterus gaoligongensis, also referred to as the Mount Gaoligong flying squirrel. This new to science species was described in a paperpublished in the open-access journal ZooKeys.
“The morphological features of B. gaoligongensis are closer to the critically endangered and missing Namdapha flying squirrel, but is still readily identifiable as a distinct species,” explains Quan Li.
“The new species was discovered in the ‘blank area’ spanning 1,250 km between the isolated habitats of the two known species, which suggests that the genus is much more widespread than previously thought. There is still hope for new Biswamoyopterus populations to be discovered in between or right next to the already known localities,” he says.
As for the conservation status of the newly described species, the researchers note that it inhabits low-altitude forests which are in close proximity to nearby human settlements. Thereby, they are vulnerable to anthropogenic threats, such as agricultural reclamation and poaching.
“Therefore, there is an urgent need to study the ecology, distribution, and conservation status of this rare and very beautiful genus,” concludes the lead author.

New open-access book presents a comprehensive report on the remarkable ecosystems of the Koytendag nature reserve
Situated in the extreme south-east of Turkmenistan: on the border with Uzbekistan and close to the border with Afghanistan, Koytendag presents one of the most distinct landscapes in Central Asia. Reaching elevations of up to 3,137 m, this is also the highest mountain in Turkmenistan.
Location of Koytendag Image by Atamyrat Veyisov
Koytendag State Nature Reserve and its three Wildlife Sanctuaries: Hojapil, Garlyk and Hojaburjybelent, were established between 1986 and 1990 to protect and preserve the mountain ecosystem of the Koytendag region and maintain the ecological balance between the environment and increasing economic activities.
Since 2013, a series of scientific expeditions and assessments were coordinated and funded by the Royal Society for the Protection of Birds (RSPB) to pave the way for the protection and preservation of the unique landscape and rare wildlife the site is recognised for.
As a result, the efforts of the conducted field studies of multidisciplinary international research teams are brought together in a comprehensive report, which is now openly available as an Advanced Book from the scientific publisher and technology provider Pensoft, edited by Geoff Welch (RSPB) and Prof. Pavel Stoev (National National Museum of Natural History of Bulgaria and Pensoft). Soon, the book will also be available in Russian.
The book is split into eight sections focused on different areas within the study of biodiversity: Flora, Surface dwelling invertebrates, Cave fauna, Fish, Amphibians, Reptiles, Birds and Mammals. An additional chapter is dedicated to the hydrogeology of the site because of its key role in supporting both the cave fauna and the local communities.

In the summary of the report, the authors make a list of the most significant findings made during the research. These include the discovery of a cave hosting the largest underground lake in the whole North Eurasia (4,400 m2) and a total of 48 species of higher plants that can only be found in Koytendag. In terms of Koytendag’s surface-dwelling fauna, the report lists a number of species new to science: a scorpion (most likely yet unnamed species currently recognised as a species complex) and a spider. Meanwhile, a total of seven previously unknown species were found underground, including the very first exclusively subterranean animal found in the country: the insect-like ‘marvellous’ dipluran named Turkmenocampa mirabilis, and a strongly adapted to the underground waters of a desert sinkhole Gammarus troglomorphus. Additionally, the annual monitoring, conducted since 1995 by the reserve staff, report an encouraging increase in the populations of the rare markhors and mouflons. An intact predator-prey community was also identified as a result of observations of numerous Eurasian lynxes and grey wolves, as well as prey species.

Stephanie Ward, RSPB Central Asia Partner Development Officer, says:
“RSPB has been working in Turkmenistan under a Memorandum of Understanding with the Government since 2004. In that time we have had the privilege of working with a team of talented and dedicated national experts across the diverse and inspiring nature of this fascinating country. Our work in Koytendag has captured the attention and interest of many international scientists who hope that their contemporary biodiversity research will help to deepen the understanding and therefore ensure protection of the unique wonders of this mountain ecosystem. As a potential UNESCO World Heritage Site, we will continue to collaborate with the Turkmen people on the research and promotion of Koytendag State Nature Reserve.
Book editor and member of the research team Prof. Pavel Stoev adds:
“Koytendag Mountain is among the least explored and, simultaneously, one of the most biologically diverse regions in Central Asia. The rapid assessments of its flora and fauna revealed a high number of highly specialised species, all of which have undergone a long evolution to adapt to the harsh environments of the mountain. The establishment of Koytendag State Nature Reserve and the associated wildlife sanctuaries is a step in the right direction for the protection of this unique biota.”

Newly described ‘brushed’ jumping spider species Jotus karllagerfeldi and its famous namesake: fashion icon and designer, creative director, artist, photographer and caricaturist Karl Lagerfeld (1933-2019).

New to science species of Australian jumping spider was named after Hamburg-born fashion icon Karl Lagerfeld (1933-2019) after the arachnid reminded its discoverers of the designer. Intrigued by its distinct ‘downplayed’ black-and-white colours, the Hamburg-Brisbane-Melbourne team likened the spider’s appearance to Lagerfeld’s trademark style: his white hair and Kent collar that contrasted with the black sunglasses and gloves.

When compared with other members in the ‘brushed’ jumping spider genus Jotus, the novel species clearly stands out due to its black-and-white legs and tactile organs (pedipalps), whereas the typical representative of this group demonstrates striking red or blue colours.
“The animal reminded us with its colours of the reduced style of Karl Lagerfeld. For example, we associate the black leg links with the gloves he always wore”, Danilo Harms explains.

In fact, what was to be now commonly referred to as Karl Lagerfeld’s Jumping Spider was identified amongst specimens in the Godeffroy Collection. Kept at CeNak, the historical collection was originally compiled by the inquisitive and wealthy tradesman from Hamburg Johann Cesar Godeffroy, who financed several expeditions to Australia back in the 19th century. Here, the research team identified another link between Australia, Godeffroy, Hamburg and Jotus karllagerfeldi.
Besides the tiny (4 to 5 mm) arachnid, whose pedipalps resemble a white Kent collar, the scientists describe another seven new to science species and add them to the same genus. Two of those, Jotus fortiniae and Jotus newtoni, were also named after inspirational figures for their hard work and creativity: educator, molecular biologist and science communicator Dr Ellen Fortini (Perth College, Western Australia) and keen naturalist and photographer Mark Newton. All novel species were found either in the Godeffroy Collection or amongst the jumping spiders housed at Queensland Museum.
Surprisingly, even though the genus Jotus comprises numerous species found all over Australia, there is not much known about these spiders. An interesting feature, according to the scientists behind the present study, are the huge telescopic eyes, which allow for spatial vision. The Jotus species need this ability in foraging, since they do not weave webs, but rather hunt in the open. Thus, they have evolved into extremely fast and agile hunters, capable of jumping short distances.
Curiously, back in 2017, the team of Barbara and Danilo, joined by Dr Robert Raven from Queensland Museum, described another previously unknown, yet fascinating species: a water-adapted spider, whose sudden emergence at the coastline of Australia’s “Sunshine State” of Queensland during low tide in January brought up the association with reggae legend Bob Marley and his song “High Tide or Low Tide”. The species, scientifically known as Desis bobmarleyi, was also published in Evolutionary Systematics.

In an unexpected discovery from New Zealand, two species of narrowly distributed moths were described as new species. Interestingly, both Arctesthes titanica and Arctesthes avatar were named after mythological deities and top-grossing blockbusters by famous filmmaker James Cameron: Titanic and Avatar, respectively.

In an unexpected discovery from the South Island (New Zealand), two species of narrowly distributed macro-moths were described as new species. Interestingly, both Arctesthes titanica and Arctesthes avatar were named after mythological deities and top-grossing blockbusters by famous filmmaker James Cameron: Titanic and Avatar, respectively.
Each of the newly described species are believed to be restricted to only a couple of subalpine/alpine localities. Therefore, they are particularly vulnerable to extinction and need to be “considered of very high priority for conservation”, point out New Zealand scientists Brian Patrick (Wildland Consultants Ltd), Hamish Patrick (Lincoln University) and Dr Robert Hoare (Manaaki Whenua-Landcare Research) in their paper in the open-access journal Alpine Entomology.

Because of its relatively large size, one of the new discoveries: A. titanica, was named in reference to the Titans: the elderly gods in Greek mythology and the legendary, if ill-fated, record-breaking passenger ship ‘Titanic’, which became the subject of the famous 1997 American epic romance and disaster film of the same name. Unfortunately, the moth’s small wetland habitat is located in an area that is currently facing a range of damaging farming practices, such as over-sowing, grazing, stock trampling and vehicle damage.
On the other hand, A. avatar received its name after Forest & Bird, the New Zealand conservation organisation that was behind the 2012 BioBlitz at which the new species was collected, ran a public competition where “the avatar moth” turned up as the winning entry. The reference is to the indigenous people and fauna in Avatar. Just like them, the newly described moth is especially vulnerable to habitat change and destruction. In addition, the study’s authors note that the original avatars came from Hindu mythology, where they are the incarnations of deities, including Vishnu, for example, who would transform into Varaha the boar.
In conclusion, the scientists point out that future studies to monitor and further understand the fauna of New Zealand are of crucial importance for its preservation:
“Quantitative studies as well as work on life histories and ecology are particularly needed. Already one formerly common endemic geometrid species, Xanthorhoe bulbulata, has declined drastically and is feared possibly extinct: its life history and host-plant have never been discovered. Without further intensive study of the fauna of modified and threatened New Zealand environments, we will be unable to prevent other species slipping away.”

A study of parasitic crustaceans attaching themselves inside the branchial cavities (the gills) of their fish hosts was recently conducted in order to reveal potentially unrecognised diversity of the genus Elthusa in South Africa.
While there had only been one species known from the country, a new article published in the open-access journal ZooKeys adds another three to the list.
For one of them, the research team from North-West University (South Africa): Serita van der Wal, Prof Nico Smit and Dr Kerry Hadfield, chose the name of the fictional character Xena, the warrior princess. The reason was that the females appeared particularly tough with their characteristic elongated and ovoid bodies. Additionally, the holotype (the first specimen used for the identification and description of the previously unknown species) is an egg-carrying female.
Formally recognised as Elthusa xena, this new to science species is so far only known from the mouth of the Orange River, Alexander Bay, South Africa (Atlantic Ocean). It is also the only Elthusa species known to parasitise the intertidal Super klipfish (Clinus supercilious). In fact, this is the first time an Elthusa species has been recorded from any klipfish (genus Clinus).
