Taxonomist Day at Pensoft: Three species in the WoRMS’ Top 10 Marine Species of 2019 described in our journals

Happy Taxonomist Appreciation Day, everyone!

In a lovely tradition, the World Register of Marine Species (WoRMS) issued the Top 10 Marine Species of 2019 for the ninth time around on time for this special day! 

In what has also already become a tradition we are particularly proud of, it’s not one, but several species described as new to science in Pensoft journals that make it to the renowned list! Even if it’s a slight step back from last year’s five entries, this year, we see a total of three species making it to the list: the Vibranium Fairy Wrasse (Cirrhilabrus wakanda) and the Green Rat Clingfish (Barryichthys algicola), both published in ZooKeys, and Thiel’s Boring Amphipod (Bircenna thieli) first known from the pages of Evolutionary Systematics.

Struggling to put a face to the name? Let us bring the stories behind these fantastic discoveries for you: 


The real-life fairy wrasse, whose scales shine bright like sci-fi vibranium

Even if the “twilight zone” – the ocean depths from 60 to 150 meters underneath the water surface, are long known to be teeming with all sorts of fascinating reef-dwelling lifeforms that still await discovery, California Academy of Sciences’ (CAS) initiative Hope for Reefs and partners are already concerned with the protection of these fragile habitats. One of the ways they do this is by deploying the taxonomic approach: recording and defining every creature the current environmental crisis could be putting in danger.

One of the latest discoveries made by the CAS team and Yi-Kai Tea, lead author and PhD student at the University of Sydney, is a stunning wrasse species with colours so mesmerising and vibrant that immediately triggered the creativity of the scientists. Discovered amongst the dusky coral reefs of eastern Zanzibar, off the coast of Tanzania, the species received the scientific name Cirrhilabrus wakanda in a nod to the Marvel Entertainment comics and movie Black Panther, where Wakanda is a mythical nation. 

The fish also goes under its common name: Vibranium Fairy Wrasse, because of its hypnotising scales reminiscent of the fictional metal. In the franchise, the vibranium is a rare, robust and versatile ore capable of manipulating energy. In its turn, the scales of the Vibranium Fairy Wrasse have a pigment so strong, their shades survive even when preserved.

“When we thought about the secretive and isolated nature of these unexplored African reefs, we knew we had to name this new species after Wakanda,”

said Yi-Kai Tea.

The clingy, yet long unknown green fish

You might think that a common name for a genus of tiny, less than 21 mm long marine inhabitants, such as ‘Rat Clingfish’ is way too unusual already, but it’s getting even more curious when you find out about those species’ mind-boggling lifestyle. 

These two miniature clingfishes were first spotted around microalgae in Australia back in the 1980s and since then they would puzzle scientists so much they would simply refer to them as “Genus B”. However, this was about to change, when in 2019, the US-Australian research team of Drs Kevin W. Conway, Glenn I. Moore and Adam P. Summers collected and studied enough specimens found in dense stands of macroalgae in intertidal and shallow subtidal areas along the coast of southern Australia. There, the two clingfishes use their well-developed adhesive discs located on their tummies to attach to the microalgae. Because of their miniature size, they have evolved multiple reduced and novel distinctive features.

As a result of their study, we now have the genus Barryichthys, whose common name is Rat Clingfish, and two new to science species assigned to it: the Brown Rat Clingfish (Barryichthys hutchinsi) and the Green Rat Clingfish (Barryichthys algicola), where the latter was found to be particularly intriguing thanks to its peculiar green colouration and a species name translated to “one who inhabits the algae”.

The boring vegetarian amphipod  

Another impressive creature with a taste for algae described in 2019 from Australia is the Thiel’s Boring Amphipod, which is indeed boring. The tiny crustacean, which can be found in colonies of hundreds in Tasmania, eats its way through its favourite bull kelp leaving behind tunnels.

Another peculiarity about the species is its head, which when seen from the front resembles that of an ant!

With its species name: Bircenna thieli, the scientists behind the study – Drs Elizabeth Hughes (Natural History Museum of London, UK) and Anne-Nina Lörz (University of Hamburg, Germany) pay tribute to respected crustacean expert Prof. Dr. Martin Thiel, who had originally collected some of the studied specimens.

Major advances in our understanding of New World Morning Glories

A major advance in revealing the unknown plant diversity on planet Earth is made with a new monograph, published in the open-access, peer-reviewed journal PhytoKeys. The global-wide study, conducted by researchers at the University of Oxford, lists details about each of the 425 New World species in the largest genus within the family of morning glories, thanks to an all-round approach combining standard, modern and new-generation identification techniques. 

The family of morning glories, also known as bindweeds, whose scientific name is Convolvulaceae, includes prominent members like the sweet potato and ornamental plants such as the moonflower and the blue dawn flower. In fact, one of the key conclusions, made in the present work, is that within this plant group there are many other species, besides the sweet potato, that evolved storage roots long before modern humans appeared on Earth. Furthermore, most of those are yet to be evaluated for economic purposes.

To make their findings, the research team of John Wood, Dr Pablo Muñoz Rodríguez, Bethany R.M. Williams and Prof Robert Scotland applied the “foundation monograph” concept that they had developed for similarly diverse and globally distributed, yet largely understudied groups. Usually, such groups with hundreds of species have never been surveyed across their entire geographical range, which in turn results in the existence of many overlooked new species or species wrongly named.

As a result, the monograph adds six new to science species and establishes nine new subspecies, previously recognised as either distinct species or varieties. The publication also cites all countries where any of those 425 morning glories occurs. In order to provide detailed knowledge about their identities and ecologies, the authors also produced over 200 illustrative figures: both line drawings and photos.

In their study, the scientists also investigate poorly known phenomena concerning the genus. For instance, the majority of the plants appear to originate from two very large centres, from where they must have consequently radiated: the Parana region of South America and the Caribbean Islands. Today, however, a considerable amount of those species can be found all around the globe. Interestingly, the team also notes a strong trend for individual species or clades (separate species with a common ancestor) to inhabit disjunct localities at comparable latitudes on either side of the tropics in North America and South America, but not the Equator.

The monograph exemplifies the immense value of natural history collections. Even though the researchers have conducted fieldwork, most of their research is based on herbarium specimens. They have even managed to apply DNA sequencing to specimens over 100 years old. The publication also provides detailed information about the characteristics, distribution and ecology of all the species. It is illustrated with over 200 figures, both line drawings and photos.

“A major challenge in monographing these groups is the size of the task given the number of species, their global distribution and extensive synonymy, the large and increasing number of specimens, the numerous and dispersed herbaria where specimens are housed and an extensive, scattered and often obscure literature,”

comment the scientists.

“Unlike traditional taxonomic approaches, the ‘foundation monograph’ relies on a combination of standard techniques with the use of online digital images and molecular sequence data. Thereby, the scientists are able to focus on species-level taxonomic problems across the entire distribution range of individual species,”

they explained.

In a separate paper, published in Nature Plants last November, the research team provides further insights into how they have assembled the monograph and include all the molecular sequence data and phylogenetics produced during their work.

Book on plants in the Murmansk region (Russia) scores 4/19 correct insect identifications

Mistakes can occur in any environment, but what if the records we read about are actually incorrect? The case of unqualified scientists publishing false records of insects in the Murmansk oblast of Russia is described in the recent paper in the open-access journal Arctic Environmental Research.

A recently published book on some aspects of the ecology of woody introducents in the Murmansk oblast of Russia provides the information on 19 species of plant-damaging insects out of which only 4 species are identified correctly. Dr Mikhail V. Kozlov from the University of Turku provides correct identifications for the insects, illustrated in the book, in his paper, published in the open-access journal Arctic Environmental Research in order to prevent the spread of erroneous information across future publications and databases.

Insect fauna of the Murmansk region is relatively well-studied and that’s why any new faunistic records from this region immediately attract the attention of entomologists. Those findings are especially exciting when they extend the distribution range of certain species by 1,000 to 2,000 km towards the North Pole.

The published misidentifications of insect species can lead to a cascading effect of mistakes, because entomologists commonly use faunistic data published by colleagues decades and even centuries ago. That’s why it is very important to keep a track of such cases and provide correct identifications if possible, remarks the author.

“In particular, three moth species (Archips crataegana, A. podanaand Erannis defoliaria) reported in this book to occur around Kirovsk have not yet been found either in the Murmansk oblast or in the more southern Karelia. In neighbouring Finland, the northernmost records of these species are from locations some 1,000 km to the south of Kirovsk”,

Dr Kozlov shares his concerns.

The most striking examples of misidentification in the book are at the order level: a syrphid fly (Diptera) identified as a leafcutter bee (Hymenoptera), and a sawfly (Hymenoptera) identified as a psyllid (Hemiptera).

In conclusion, Dr Kozlov’s revision found that 15 out of the 19 species illustrated were incorrectly identified. Thus, the leaf damage associated with certain insect species, considered in the book, also becomes very questionable.

“The misidentification of pest species can easily result in incorrect pest management and face unnecessary costs, while publication of incorrect data distorts our knowledge of the distribution and biology of insects. Therefore, insect identification for scientific, educational or pest management purposes should always be performed by professionals or by volunteers and students who have specific training for this
purpose”,

concludes Dr Mikhail V. Kozlov.

French mathematician and spider aficionado Cédric Villani honoured with a new orb-weaver

Considered as one of the best studied spiders, the orb-weavers remain poorly known in the central parts of the Palearctic ecozone. Hence, an international research team took to the Caucasus, Middle East and Central Asia. Their article in the open-access peer-reviewed journal ZooKeys documents three new-to- science species, where one is named after the Indo-Iranian god of light Mithra. Another carries the name of the flamboyant French mathematician and spider aficionado Cédric Villani.

With their astonishingly precise spiral webs, orb-weaving spiders are the arachnid analogy of first-class mathematicians, note the researchers behind the study

Despite being considered as one of the best-studied spiders in the Palearctic, the orb-weaver spiders (family Araneidae) remain poorly known in the central parts of the ecozone. To bridge the knowledge gaps, an international research team of researchers took to the Caucasus, Middle East and Central Asia to study two of those genera: Araniella and Neoscona. 

As a result, in their article, recently published in the open-access scientific journal ZooKeys, arachnologists Alireza Zamani (University of Turku, Finland), Yuri M. Marusik (Institute for Biological Problems of the North RAS, Russia) and Anna Šestáková (The Western Slovakian Museum, Slovakia) describe three new-to-science species, where one: Araniella villanii – carries the name of the flamboyant French mathematician and spider aficionado Cédric Villani, who has been dubbed the “Lady Gaga of Mathematics”. Even if unknown until now, the species turned out to have a wide distribution, ranging from south-western Iran to eastern Kazakhstan and northern India.

“It’s a well-known fact within the arachnological community that spiders are masters of mathematics and architecture. Orb-web spiders, in particular, tend to build beautiful and architecturally aesthetic webs, some of which are formed in spirals in line with the repetitive pattern of the golden ratio,”

explains lead author of the study Alireza Zamani.

The web of the garden orb-web spider Araneus diadematus, for example, usually has 25 to 30 radial threads forming an astonishingly precise angle of about 15°, which the spider carefully measures using its front legs. According to scientific observations, if the front legs are removed, the regularity of the angles between adjacent radial threads is impaired.

For these and many other reasons, spiders must have been an inspiration for mathematicians like Cédric Villani, who has publicly shown a mysterious love for these arachnids. Awarded the Fields Medal (some say it is the Mathematics equivalent of the Nobel Prize) in 2010 and having served as the director of Sorbonne University‘s Institut Henri Poincaré from 2009 to 2017, the Frenchman’s love for spiders is quite evident, thanks to the constant presence of a spider brooch on his lapel. Although he has never explained the reason behind his appreciation of these eight-legged wonders, now he has a real, even scientifically sound connection to them in the real world. 

Apart from Araniella villanii, whose scientific name honours the prominent scientist and recognises his love for spiders, the other two newly-described species also have a story behind their names. One of them: Neoscona isatis, discovered in central Iran, was named after the historical name of its type locality; and Araniella mithra, known from north-western, central and south-western Iran, was named after Mithra, the god of light in the ancient Indo-Iranian mythology.

Curiously, spiders in the genus Araniella are green in colour due to certain bile pigments (biliverdin) that make them very difficult to spot in their natural habitat, as they live mostly on leaves.

“I met Mr. Villani in May 2015 at University of Tehran, where he was an invited speaker. We got to briefly talk about our shared interest in spiders, and I had the opportunity to present him an Iranian wolf spider as a souvenir!”

recalls Zamani.

“It’s important to note that, with the efforts of taxonomists, new species are being discovered and described with an average rate of 18,000 species per year, but simultaneously both known and undescribed species go extinct due to human activities, with the current rate being within or even higher than the range of the newly described ones. A first step towards conservation of biodiversity includes taxonomic research to document species and to define hotspots of species diversity in order to protect such carefully selected habitats,”

he points out.

“However, with the current situation of low funding for taxonomic research, the number of students doing taxonomic research is in severe decline and the current average ‘shelf life’ (between discovery and description) of a new species remains at about 21 years. Araniella villanii is a great example of how much we don’t know about our biodiversity.”

Despite being discovered all the time, new species mostly have very restricted ranges and are only known from a few nearby localities. Orb-weaver spiders have very good dispersal abilities and it is relatively uncommon to detect new species of them.

“Araniella villanii is known from a few localities in southwestern Iran, eastern Kazakhstan and northern India, a distribution range covering at least ten countries, and yet the species was unknown to science until now. I think that the message that this particular discovery implies is that while there are such widely-distributed undescribed species out there, we need more and more taxonomic research, both in the field and in the natural history museum collections, which house a considerable number of undescribed species, in order to preserve the remaining biodiversity on earth, before it’s too late”.

Second of its kind ‘sharpshooter’ leafhopper from Brazil ‘strikes’ with its colouration

When, in 2014, Brazilian researchers stumbled across a never-before-seen red-eyed leafhopper feeding inside the rosettes of bromeliads, growing in the restingas of southeastern Brazil, they were certain it was a one-of-a-kind discovery. Described as new-to-science species, as well as genus (Cavichiana bromelicola) and added to the sharpshooter tribe Cicadellini, it became the first known case of a leafhopper feeding on otherwise nutrition-poor bromeliads in their natural habitat.

Several years later, however, a team of entomologists from Universidade Federal do Rio de Janeiro carried out fieldwork in a mountainous area of southeastern Brazil and, as a result, another bromelicolous leafhopper species of the genus was discovered: Cavichiana alpina. Only, the new one appeared even more spectacular. 

The new species, described and illustrated in the open-access journal Zoologia, is known from Itatiaia National Park (southeastern Brazil), where it can be found at altitudes above 1,800 m a.s.l. In fact, its characteristic mountainous habitat came to determine its species name (alpina). In contrast, its relative was originally described exclusively from sea level regions, even though the latest field trips have recorded it from a site located at 1,250 m a.s.l. 

Slightly larger than the previously known C. bromelicola and similarly red-eyed, what most remarkably sets apart the newly-described species is its colouration. Rather than a single large yellow blotch contrasting against the dark-brown to black back of the insect, this sharpshooter sports a motley amalgam of red and blue covering most of its upper side.

In conclusion, the researchers explain that the peculiarity of the two known Cavichiana species is best attributed to a putative common ancestor that had likely once been widely distributed in southeastern and southern Brazil. Later, they speculate, a vicariant event, such as the uplift of the southeastern Brazilian mountain ranges during the latest Eocene and Oligocene, might have caused its diversification into two separate species.

Facebook and Instagram gave away the presence of the ‘Japan pig’ seahorse in Taiwan

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.

Plant diversity and endemism in China: unreachable locations and diverse microclimates

The newly described Bulbophyllum reflexipetalum

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.

Another team from the Guizhou University of Traditional Chinese Medicine and KIB describes a new representative of the parachute flowers. Ceropegia jinshaensis, characterized by the shape and size of its leaves and flowers. 


“More conservation efforts are needed in this region to counteract the increasing anthropogenic disturbance and destruction”, state the leading authors from KIB, who discovered a new species of orchid in the Eastern Himalaya biodiversity hotspot.

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.

Revolutionary method could bring us much closer to the description of hyperdiverse faunas

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,”

explain the researchers behind a new study, published in the open-access journal Deutsche Entomologische Zeitschrift (DEZ).
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.

The first bioluminescent click beetle known from Asia represents a new subfamily

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.

“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.

UCF student names a new frog species after her professor

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.

Urgiles and an international team of researchers published their findings in the journal ZooKeys.

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.
