On the one hand, the publication is remarkable because of the large number of new species of frogs. Regarding vertebrate animals, most studies only list between one and five new to science species, because of the difficulty of their collection and the copious amount of work involved in the description of each. To put it into perspective, the last time a single article dealt with a similar number of newly discovered frogs from the western hemisphere was in 2007, when Spanish scientist Ignacio de la Riva described twelve species from Bolivia.
The Rain frogs comprise a unique group lacking a tadpole stage of development. Their eggs are laid on land and hatch as tiny froglets. Image by BIOWEB-PUCE.
On the other hand, the new paper by Nadia Paez and Dr Santiago Ron is astounding due to the fact that it comes as part of the undergraduate thesis of Nadia Paez, a former Biology student at the Pontifical Catholic University, where she was supervised by Professor Santiago Ron. Normally, such a publication would be the result of the efforts of a large team of senior scientists. Currently, Nadia Paez is a PhD student in the Department of Zoology at the University of British Columbia in Canada.
Unfortunately, amongst the findings of concern is that most of the newly described frog species are listed as either Data Deficient or Threatened with extinction, according to the criteria of the International Union for Conservation of Nature (IUCN). All of the studied amphibians appear to have very restricted geographic ranges, spanning less than 2,500 km2. To make matters worse, their habitats are being destroyed by human activities, especially cattle raising, agriculture, and mining.
Amongst the newly described species, there is the peculiar Multicolored Rain Frog, where the name refers to its outstanding color variation. Individuals vary from bright yellow to dark brown. Initially, the studied specimens were assumed to belong to at least two separate species. However, genetic data demonstrated that they represented a single, even if highly variable, species.

The rest of the previously unknown frogs were either named after scientists, who have made significant contributions in their fields, or given the names of the places they were discovered, in order to highlight places of conservation priority.

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.

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.

Named for Black Panther’s mythical nation of Wakanda, a dazzling new “Vibranium” Fairy Wrasse enchants with purple scales and a preference for deep, little-known mesophotic reefs up to 260 feet below the surface
Africa has new purple-clad warriors more than 200 feet beneath the ocean’s surface. Deep-diving scientists from the California Academy of Sciences’ Hope for Reefs initiative and the University of Sydney spotted dazzling fairy wrasses—previously unknown to science—in the dimly lit mesophotic coral reefs of eastern Zanzibar, off the coast of Tanzania.
The multicolored wrasses sport deep purple scales so pigmented, they even retain their color (which is typically lost) when preserved for research. The scientists name this “twilight zone” reef-dweller Cirrhilabruswakanda (common name “Vibranium Fairy Wrasse”)in honor of the mythical nation of Wakanda from the Marvel Entertainment comics and movie Black Panther. The new fish is described in the open-access journal Zookeys.
Yi-Kai Tea, lead author and ichthyology PhD student from the University of Sydney, says:
“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. We’ve known about other related fairy wrasses from the Indian Ocean, but always thought there was a missing species along the continent’s eastern edge. When I saw this amazing purple fish, I knew instantly we were dealing with the missing piece of the puzzle.”
The Academy scientists say Cirrhilabruswakanda’s remote home in mesophotic coral reefs—below recreational diving limits—probably contributed to their long-hidden status in the shadows of the Indian Ocean.
Therefore, Hope for Reefs’ scientific divers are highly trained for the dangerous process of researching in these deep, little-known mesophotic reefs, located 200 to 500 feet beneath the ocean’s surface. Accessing them requires technical equipment and physically intense training well beyond that of shallow-water diving. The team’s special diving gear (known as closed-circuit rebreathers) includes multiple tanks with custom gas blends and electronic monitoring equipment that allow the divers to explore deep reefs for mere minutes before a lengthy, hours-long ascent to the surface.
Dr. Luiz Rocha, Academy Curator of Fishes and co-leader of the Hope for Reefs, comments:
“Preparation for these deep dives is very intense and our dive gear often weighs more than us. When we reach these reefs and find unknown species as spectacular as this fairy wrasse, it feels like our hard work is paying off.”
Using a microscope, the team examined the specimens’ scales, fin rays, and body structures. DNA and morphological analyses revealed the new fairy wrasse to be different from the other seven species in the western Indian Ocean as well as other relatives in the Pacific. The new species’ common name is inspired by the fictional metal vibranium, a rare, and, according to Rocha, “totally awesome” substance found in the nation of Wakanda. The Vibranium Fairy Wrasse’s purple chain-link scale pattern reminded the scientists of Black Panther’s super-strong suit and the fabric motifs worn by Wakandans in the hit film.
Precious life in deep reefs
In a recent landmark paper, the Academy team found that twilight zone reefs are unique ecosystems bursting with life and are just as vulnerable to human threats as their shallow counterparts. Their findings upended the long-standing assumption that species might avoid human-related stressors on those deeper reefs. The Hope for Reefs team will continue to visit and study twilight zone sites around the world to shed light on these often-overlooked ecosystems.
In addition to this new fish from Zanzibar, Rocha and his colleagues recently published descriptions of mesophotic fish from Rapa Nui (Easter Island) and Micronesia. Luzonichthys kiomeamea is an orange, white, and sunny yellow dwarf anthias endemic to Rapa Nui, and the basslet Liopropoma incandescens (another new species published today in Zookeys) inhabits Pohnpei’s deep reefs—a neon orange and yellow specimen collected from a rocky slope 426 feet beneath the ocean’s surface.
“It’s a time of global crisis for coral reefs, and exploring little-known habitats and the life they support is now more important than ever,” concludes Rocha. “Because they are out of sight, these deeper reefs are often left out of marine reserves, so we hope our discoveries inspire their protection.”

Specimens kept in the collection of the Institute of Beneficial Insects at the Fujian Agriculture and Forestry University (FAFU, China) revealed the existence of two previously unknown species of endoparasitoid wasps. Originally collected in 2013, the insects are known to inhabit prairies and bushes at above 3,400 m, which is quite an unusual altitude for this group of wasps.
The new to science wasps are described and illustrated in a paper published in the open-access, peer-reviewed scholarly journal ZooKeys by the team of Dr Wangzhen Zhang (FAFU and Fuzhou Airport Inspection and Quarantine Bureau) and his colleagues at FAFU: Dr Dongbao Song and Prof Jiahua Chen.
Looking very similar to each other, the species were found to belong to one and the same genus (Microplitis), which, however, is clearly distinct from any other within the subfamily, called Microgastrinae. The latter group comprises tiny, mostly black or brown wasps that develop in the larvae of specific moths or butterflies. Interestingly, once parasitised, the host continues living and does not even terminate its own growth. It is only killed when the wasp eggs hatch and feed on its organs and body fluids before spinning cocoons.
From now on, the newly described wasps will be called by the scientific names Microplitis paizhensis and Microplitis bomiensis, where their species names refer to the localities from where they were originally collected: Paizhen town and Bomi county, respectively.
Due to their parasitism, some microgastrine wasps are considered important pest biocontrol agents. Unfortunately, the hosts of the newly described species remain unknown.
In addition, the scientists also mention a third new to science species spotted amongst the specimens they studied. However, so far they have only found its male, whereas a reliable description of a new microgastrine wasp requires the presence of a female.

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).

A 3D reconstruction of the fossil allowed for the description of an entirely new suborder
The newly described millipede (Burmanopetalum inexpectatum) rendered using 3D X-ray microscopy. Image by Leif Moritz.
Even though we are led to believe that during the Cretaceous the Earth used to be an exclusive home for fearsome giants, including carnivorous velociraptors and arthropods larger than a modern adult human, it turns out that there was still room for harmless minute invertebrates measuring only several millimetres.
Such is the case of a tiny millipede of only 8.2 mm in length, recently found in 99-million-year-old amber in Myanmar. Using the latest research technologies, the scientists concluded that not only were they handling the first fossil millipede of the order (Callipodida) and also the smallest amongst its contemporary relatives, but that its morphology was so unusual that it drastically deviated from its contemporary relatives.
As a result, Prof. Pavel Stoev of the National Museum of Natural History (Bulgaria) together with his colleagues Dr. Thomas Wesener and Leif Moritz of the Zoological Research Museum Alexander Koenig (Germany) had to revise the current millipede classification and introduce a new suborder. To put it in perspective, there have only been a handful of millipede suborders erected in the last 50 years. The findings are published in the open-access journal ZooKeys.
To analyse the species and confirm its novelty, the scientists used 3D X-ray microscopy to ‘slice’ through the Cretaceous specimen and look into tiny details of its anatomy, which would normally not be preserved in fossils. The identification of the millipede also presents the first clue about the age of the order Callipodida, suggesting that this millipede group evolved at least some 100 million years ago. A 3D model of the animal is also available in the research article.
Curiously, the studied arthropod was far from the only one discovered in this particular amber deposit. On the contrary, it was found amongst as many as 529 millipede specimens, yet it was the sole representative of its order. This is why the scientists named it Burmanopetalum inexpectatum, where “inexpectatum” means “unexpected” in Latin, while the generic epithet (Burmanopetalum) refers to the country of discovery (Myanmar, formerly Burma).
Lead author Prof. Pavel Stoev says:
We were so lucky to find this specimen so well preserved in amber! With the next-generation micro-computer tomography (micro-CT) and the associated image rendering and processing software, we are now able to reconstruct the whole animal and observe the tiniest morphological traits which are rarely preserved in fossils. This makes us confident that we have successfully compared its morphology with those of the extant millipedes. It came as a great surprise to us that this animal cannot be placed in the current millipede classification. Even though their general appearance have remained unchanged in the last 100 million years, as our planet underwent dramatic changes several times in this period, some morphological traits in Callipodida lineage have evolved significantly.

Co-author Dr. Thomas Wesener adds:
“We are grateful to Patrick Müller, who let us study his private collection of animals found in Burmese amber and dated from the Age of Dinosaurs. His is the largest European and the third largest in the world collection of the kind. We had the opportunity to examine over 400 amber stones that contain millipedes. Many of them are now deposited at the Museum Koenig in Bonn, so that scientists from all over the world can study them. Additionally, in our paper, we provide a high-resolution computer-tomography images of the newly described millipede. They are made public through MorphBank, which means anyone can now freely access and re-use our data without even leaving the desk.”
“The entire Mesozoic Era – a span of 185 million years – has until now only been sampled for a dozen species of millipedes, but new findings from Burmese amber are rapidly changing the picture. In the past few years, nearly all of the 16 living orders of millipedes have been identified in this 99-million-year-old amber. The beautiful anatomical data presented by Stoev et al. show that Callipodida now join the club.”

Known to science since 1857, a common species of true frog (a “true frog” is one assigned to the family Ranidae), found from north-eastern Honduras, through Nicaragua and Costa Rica to central Panama, turns out to have been keeping its “multiple identities” a secret all along.
According to British and Costa Rican herpetologists, who recently used DNA barcoding to study the species in question, what we currently call Warszewitsch’s frog is in fact a group of “cryptic” species. The study, conducted in the Área de Conservación Guanacaste (ACG), Costa Rica, by James Cryer, Dr Robert Puschendorf, Dr Felicity Wynne from the University of Plymouth, and Dr Stephen Price, UCL, is published in the open-access journal ZooKeys.
In their paper, the authors suggest that the well-known Central American frog species, commonly known as the Warszewitsch’s frog, may in fact consist of multiple different “cryptic” species. This phenomenon is well documented among tropical amphibian fauna, where high levels of genetic variation within populations of a single species surpass levels found between different, classified species.

By utilizing a technique known as DNA barcoding, which compares short snippets of DNA sequences between individuals sampled, the scientists analysed specimens from three different geographic areas within Costa Rica and Panama. In this case, the researchers used sequences derived from mitochondria, the energy-producing “power houses” found in animal cells. Their results indicated there was enough genetic variation to suggest cryptic species are indeed present.
The team chose this particular species because cryptic species were previously identified at two Panamanian sites. Now, the samples from Costa Rica broaden the study area, suggesting that there could be multiple species going by the name Warszewitsch’s frog all across its known distribution.
Conservation biologist and lead author James Cryer says:
“The next step will be to gather more samples throughout the full range of the species. Additionally, if we are to fully discern one species variant from another, further studies that compare the physical, behavioural and ecological characteristics of the frogs, alongside more genetic testing is needed.”
Overall, findings like these are important to help improve our understanding of amphibian biodiversity and, thus, work towards its conservation.
“If indeed there are multiple species, it may be that they have different ecological requirements, and therefore different approaches to their conservation are needed.” Cryer says. “This study further reinforces the power of DNA barcoding for rapid, preliminary species identification. Especially in the tropics, where habitat loss, climate change and infectious disease continually threaten many undescribed amphibian species.”
The World Register of Marine Species (WoRMS) announced the
Top 10 Marine Species of 2018 just in time for
Taxonomist Appreciation Day
What could be better timing to take a look back on the most spectacular animals described as new to science throughout 2018 than 19th March, Taxonomist Appreciation Day?
For the sixth time around, biologists from across the world are all hyped-up about this special date when we celebrate the experts who put things in order by giving names, identities and belonging to what the world has thought non-existent only a moment ago. After all, no sooner is a species formally acknowledged than it can be studied, understood and protected.
Having said that, at Pensoft and ZooKeys we’re immensely proud of becoming a prime publication choice for marine taxonomists from around the globe. Amongst them are the authors of not one or two, but FIVE exceptional animal curiosities, now recognised by a selected committee and the World Register of Marine Species (WoRMS), and featured in the TOP 10 Marine Species of 2018.
The “Japan Pig” which is also a… seahorse (Hippocampus japapigu)

We fail to find the obvious reason why locals diving in the waters of Hachijo-jima Island (Japan) had already likened this dazzling seahorse to a “tiny baby pig”, when a research team collected specimens and identified them as a species new to science. Naturally, the scientists assigned it with the name japapigu, which translates to “Japan Pig” in Japanese.
One thing is for sure, though, the stunning seahorse wouldn’t demand a degree in Zoology to attract anyone’s attention, had it not been for its expertise in camouflaging itself against the colourful algae-covered rocks.

The crab that chooses an animal ‘blanket’ over a shell (Paguropsis confusa)
Photo by DST/NRF ACEP – Spatial Solutions project team.
Sure, who would go for a rigid shell left behind by a random gastropod – just like “ordinary” hermit crabs do – when they could reach for a light, soft and elastic “blanket” instead?
That’s exactly what the blanket-hermit crab Paguropsis confusa and its sibling species have been doing as they evolved to live in a cosy symbiosis with sea anemones. While the translucent anemone peacefully “shares” the crab’s meals and grows its zoophytes around the soft-bodied crustacean, the latter is free to easily draw them up and down – as if they were a real silky duvet – and even completely cover its head whenever it feels threatened.
The crab species name is“confuso”in reference to its morphological resemblance to the closely related species Paguropsis typica. In fact, had it not been for the similarity, what we now call Paguropsis confuso would’ve most likely been described well over a century ago.
I was previously unaware of the 'blanket hermit crab,' which gently tugs an anemone up around its body like a cozy snuggly blanket and WAIT WHAT???
Amidst ongoing talks and grim forecasts of declining coral reefs spelling demise for the world as we know it, the discovery of this endemic to Okinawa Island (Japan) flower-like octocoral comes as a stunning reminder of Nature’s supremacy.
Described as a new genus, as well as a species new to science, the octocoral was aptly named Hana hanagasa, where “Hana”translates to “flower” in Japanese, while “hanagasa” is a traditional Okinawan headpiece, crafted in the form of hibiscus and worn by female dancers at ceremonies.

Upon writing up the description of this species of Indonesian shrimp,Leiden University’s then BSc student Werner de Gier is unlikely to have thought twice before coming up with the name bagginsi, as in Frodo and Bilbo Baggins – the most famous hobbits from J. R. R.Tolkien’s The Lord of the Rings and The Hobbit.
After all, what the researcher was looking at was a creature tiny enough to call another marine invertebrate – a tunicate – its snug home. Also, it had extremely hairy feet, a feature that would require for the identification key for all members of the species group to be updated.

The ‘secretive’ dogfish shark from Hawai’i (Squalus hawaiiensis)

One might think that an animal as large as a shark – especially if it’s the only shark species found in the waters of the Hawaiian Archipelago – would’ve “told” all its “secrets” by now, but that wasn’t the case with what we now refer to as the Hawaiian Spurdog.
Long mistaken for a stray population of a dogfish shark species originally from Japan, it wasn’t before US scientists deployed a range of elaborate tools used in species identification that it became apparent there was a previously unknown to science, short-ranged endemic shark trying to find shelter in Hawai’i.
Sadly, while the species is being depleted as bycatch, it has also demonstrated the lowest rate of genetic diversity known in a shark population to date.

Let us conclude with the words of ecologists and entomologist Dr Terry McGlynn, who started the Taxonomist Appreciation Day tradition in 2013:
“Even if you’re working on a single-species system, or are a theoretician, the discoveries and methods of systematists are the basis of your work,” he once told the Consortium of European Taxonomic Facilities (CETAF). “We need active work on taxonomy and systematics if our work is going to progress, and if we are to apply our findings. Without taxonomists, entire fields wouldn’t exist. We’d be working in darkness”.
