King of the Cave: New centipede on top of the food chain in the sulphurous-soaked Movile

A new species of endemic, troglobiont centipede was discovered by an international team of scientists in the Romanian cave Movile: a unique underground ecosystem, isolated several millions years ago during the Neogene, whose animal life only exists because of the chemosynthetic bacteria. As the largest Movile’s inhabitant, the new species can easily be crowned as the ‘king’ of this ‘hellish’ ecosystem. Aptly named Cryptops speleorex, the cave-dweller is described in the open-access, peer-reviewed journal ZooKeys.

Deemed to never see the light of the day, a new species of endemic, troglobiont centipede was discovered by an international team of scientists in the Romanian cave Movile: a unique underground ecosystem, where the oxygen in the air might be half of the amount of what we’re used to, yet the sulphurous abounds; and where the animal life only exists because of chemosynthetic bacteria feeding on carbon dioxide and methane.

This hellish ecosystem–where breathing alone could be lethal for most of us–seems to have finally crowned its king. At a size of between 46 and 52 mm in length, the centipede Cryptops speleorex is the largest of the cave’s inhabitants known to date. The new species is described in the open-access, peer-reviewed journal ZooKeys.

Already isolated from the outside world several millions years ago during the Neogene, the Movile cave has been drawing the attention of scientists ever since its unexpected discovery in 1986 by Romanian workers, searching for locations suitable for building a power plant in the southeastern parts of the country.

Surprisingly enough, despite its harsh living conditions, the Movile ecosystem was soon found to harbor a diverse and unique fauna, characterised by exceptional species endemism and specific trophic links. So far, the cave has been known to give home to the troglobiont water scorpion, liocranid and nesticid spiders, cave leeches and certainly many more yet to be discovered.

In fact, it was long thought that this unique underground ecosystem was also inhabited by surface-dwelling species widespread in Europe. Convinced that this scenario is highly unlikely, scientists Dr Varpu Vahtera (University of Turku, Finland), Prof Pavel Stoev (National Museum of Natural History, Bulgaria) and Dr Nesrine Akkari (Museum of Natural History Vienna, Austria) decided to examine a curious centipede, collected by speleologists Serban Sarbu and Alexandra Maria Hillebrand, during their recent expedition to Movile.

“Our results confirmed our doubts and revealed that the Movile centipede is morphologically and genetically different, suggesting that it has been evolving from its closest surface-dwelling relative over the course of millions of years into an entirely new taxon that is better adapted to life in the never-ending darkness,” explain the researchers.

“The centipede we described is a venomous predator, by far the largest of the previously described animals from this cave. Thinking of its top rank in this subterranean system, we decided to name the species Cryptops speleorex, which can be translated to the “King of the cave”, they add.

🎉Celebration time: here’s to 1,000 issues of ZooKeys!

With the 1,000th ZooKeys issue now hot off the press, the time has come to celebrate the millennium of Pensoft’s very first scientific journal: ZooKeys!

With the 1,000th ZooKeys issue now hot off the press, the time has come to celebrate the millennium of Pensoft’s very first scientific journal: ZooKeys!

In fact, the cause for celebration is two-fold: this year, it’s also the 10th anniversary of ZooKeys’ very special 50th issue, which marked a new era for biodiversity data publishing by introducing several innovative workflows and tools. This is when ZooKeys became an example to follow globally: a title the journal still takes pride to be holding to this day.

Articles published in ZooKeys since the journal’s launch in 2008 (data from 3/12/2020).

Today, we shall reminisce about everything along the way: from that sunny Californian morning at the Entomological Society of America meeting in 2007, where the idea about a new-age taxonomic journal in zoology sprang up in a breakfast chat between renowned entomologists and future founders of ZooKeys: Prof Lyubomir Penev and Dr Terry Erwin, to this very moment, where we’re counting over 5,500 published articles, authored by more than 8,000 researchers from 144 countries and comprising ~150,000 pages. Thus, we saw the description of one supertribe, seven tribes, five subtribes, 27 families, over 800 genera and more than 12,000 species previously unknown to science. In this journey, ZooKeys climbed up the ladder of academic rigour and trustability to become today’s most prolific open-access journal of zoology.

Even though today is the time to feel exalted and look back on our achievements and conquered milestones with ear-to-ear smiles, it is with heavy hearts that we’ll be raising our glasses tonight, as we won’t be joined by our beloved friend and founding Editor-in-Chief, Dr Terry Erwin, whom we lost on 11th May 2020. While his place in our hearts and ZooKeys’ Editorial board will never be filled, we accept our duty to help for his legacy to persist for the future generations of scientists by taking a vow to never lower our standards or cease to improve our services and care for our readers, authors, reviewers and editors alike. 

In honour of Terry, who will be remembered for his splendid personality and zealous enthusiasm for carabid beetles and the world’s immense biodiversity, we’ve opened up a special memorial volume to be published on 11th May 2021.

In fact, we have thousands of people to thank for the place ZooKeys is at right now: these are our authors, who have trusted us with their research work time and time again; our reviewers and editors, who have taken their invaluable time to promptly process submitted manuscripts; and, of course, our readers, who are using ZooKeys content to expand the world’s knowledge, either by learning and building on the findings in their own research, or by spreading the knowledge to those who will.

With a thought for our authors & readers

We’ve been striving to implement the latest and most convenient scholarly publishing technologies and innovations, and also develop some of our own to make sure that ZooKeys users enjoy their experience with our flagship journal. 

In hindsight, ZooKeys was the first journal to pioneer a lot of scholarly publishing technologies, which back in the time were quite revolutionary. Notable examples from 2008-2016 include: 

Yet, this was only the beginning. Fast forward to December 2020, we’re working even harder to build up on our achievements and evolve, so that we stay on top of our game and the scholarly publishing scene. Here are the key innovations we recently implemented in ZooKeys:

With a thought for our editors

Besides revolutionising research publishing, at Pensoft, we’re also deeply devoted to facilitating our editors in their day-to-day editorial work, as well as their long-term engagement with the journal and its progress. 

Recently, we expanded journal performance reporting services, in order to keep our editors on track with the most recent trends in their journal’s performance. Meanwhile, we’ve also taken care after the continuous improvement in those stats by implementing several features meant to facilitate and expedite the handling of manuscripts.

Follow ARPHA’s blog to keep up with the new features available to users of Pensoft’s journals and all journals hosted on ARPHA Platform.  

With a thought for the community

Naturally, research outputs are only as valuable to publish as they are valuable to the community: within and beyond academia. Ultimately, their merit is best measured by citations and readership. This is why, we shall now have a look back at the most impactful papers published in ZooKeys to date.

Author’s delight

Thanks to the indexation of ZooKeys in the research citation database of Dimensions, following the collaboration between ARPHA and Digital Science, which started in 2018, we’re now able to explore the all-time most cited publications in our flagship journal. Detailed information and links to the papers where each of those studies has been cited is available on the webpage of the article.

Reader’s delight

Thanks to ARPHA Platform’s all-roundedness and transparency, we get to explore the most read papers ever published in ZooKeys straight from the Articles section on the journal’s website.

  1. Taxonomic revision of the olingos (Bassaricyon), with description of a new species, the Olinguito (DOI: 10.3897/zookeys.324.5827)

In 2013, ZooKeys had the honour to announce the first carnivore found in the Western Hemisphere in over three decades. Further, that wasn’t ANY carnivore, but the olinguito, which National Geographic rightfully called a “fuzzy fog-dweller with a face like a teddy bear”.

  1. An extraordinary new family of spiders from caves in the Pacific Northwest (Araneae, Trogloraptoridae) (DOI: 10.3897/zookeys.215.3547)

A year prior to the description of the olinguito, a brand new family of “cave robbing” spiders emerged from the pages of ZooKeys, after US scientists found a previously unknown to science spider with “unique, toothed claws at the end of each leg” in Oregon.

  1. Family-Group Names In Coleoptera (Insecta) (DOI: 10.3897/zookeys.88.807)

A huge, first-of-its-kind catalogue containing data on all family-group names for all known extant and fossil beetles (order Coleoptera) was published in ZooKeys in an exemplary research collaboration, spanning three continents in 2011.

  1. Review of Neopalpa Povolný, 1998 with description of a new species from California and Baja California, Mexico (Lepidoptera, Gelechiidae) (DOI: 10.3897/zookeys.646.11411)

In a truly world-wide sensation, a new species of tiny moth inhabiting a narrow stretch of extremely fragile habitat running between the USA and Mexico, was named after then President-elect Donald Trump in a desperate call to protect this and other similarly vulnerable ecosystems in North America. The species currently goes by the name Neopalpa donaldtrumpi.

  1. Taxonomic revision of the tarantula genus Aphonopelma Pocock, 1901 (Araneae, Mygalomorphae, Theraphosidae) within the United States (DOI: 10.3897/zookeys.560.6264)

In 2016, US scientists described a total of 14 new to science tarantula species from what many would think to be one the best-researched countries: the United States of America. Curiously enough, one of those tarantula species, found in California near Folsom Prison – a place best known from Cash’s song “Folsom Prison Blues”, was aptly named Aphonopelma johnnycashi.  

Public’s delight

As visionaries, we’ve long realised that scientific impact goes beyond citations and journal subscribers. Communicating science to the community beyond academia is, in fact, one of the strongest components in research dissemination, as it lets the laypeople make sense of the wider world and where exactly they stand in the bigger picture. This is why we’ve been putting that special extra effort to promote research published in our journals–including ZooKeys–using press releases, blog posts and social media content (follow ZooKeys on Twitter and Facebook).

Data source: Altmetric.

Thanks to our partnership with Altmetric, we’re able to identify the top five most popular papers from ZooKeys for all times. These are the ones that have sparkled the most online discussions via social media, big news headlines, blog posts, Wikipedia and more.

  1. Review of Neopalpa Povolný, 1998 with description of a new species from California and Baja California, Mexico (Lepidoptera, Gelechiidae) (DOI: 10.3897/zookeys.646.11411)

Not only was the previously undescribed species of moth subject to a serious threat of extinction, having been exclusively known from a fragmented area along the Mexico–United States border, but the insect’s “hairstyle” was pointed out to bear a striking resemblance to the golden locks of the 45th U.S. President Donald Trump.

  1. Geology and paleontology of the Upper Cretaceous Kem Kem Group of eastern Morocco (DOI: 10.3897/zookeys.928.47517)

Published in ZooKeys earlier this year, this extensive geology and paleontology monograph presents an unprecedented in its volume and scientific value account of a large portion of the most important prehistoric vertebrate fossils ever unearthed from the famous Kem Kem beds in Morocco. “A monograph larger than Paralititan,” as a Reddit user justly pointed out.

  1. Taxonomic revision of the tarantula genus Aphonopelma Pocock, 1901 (Araneae, Mygalomorphae, Theraphosidae) within the United States (DOI: 10.3897/zookeys.560.6264)

On top of taking pride in becoming the discoverer of as many as 14 tarantula species living “right under our noses” in the US, Dr Chris Hamilton enjoyed the spotlight of Live television in his appearance on Sky News. So did a lucky specimen of the newly described species: Aphonopelma johnnycashi! Suffice it to say, the tarantula was named after the legendary American singer-songwriter for all the right reasons.

  1. Colobopsis explodens sp. n., model species for studies on “exploding ants” (Hymenoptera, Formicidae), with biological notes and first illustrations of males of the Colobopsis cylindrica group (DOI: 10.3897/zookeys.751.22661)

Apparently, ants that rip their bodies apart in a self-sacrificial attempt to save their colonies from enemies, weren’t something new by the time PhD student Alice Laciny and her team described the new to science species Colobopsis explodens from Brunei. However, the study published in ZooKeys in 2018 was the first to conduct and film experiments on the peculiar exploding behaviour. Although not the very first for science, C. explodens was the first “T-ant-T” species to be described since 1935.

  1. Mapping the expansion of coyotes (Canis latrans) across North and Central America (DOI: 10.3897/zookeys.759.15149)

Today, coyotes live all around North America: from Alaska to Panama, California to Maine. Once upon a time, or rather, between the Holocene and the early 1900s, their range used to be restricted to the arid west of North America. So, how did the coyotes turn up at the doorstep of South America? North Carolina scientists reached to natural history collections to map the historic colonisation of the coyotes all the way to our days.

Tiny cave snail with muffin-top waistline rolls out of the dark in Laos

A new species of tiny cave snail that glistens in the light and has a muffin-top-like bulge, was discovered by Marina Ferrand of the French Club Etude et Exploration des Gouffres et Carrières (EEGC), during the Phouhin Namno caving expedition in Tham Houey Yè cave in Laos in March 2019. The new species, named Laoennea renouardi was described in the open-access, peer-reviewed journal Subterranean Biology.

The new species, Laoennea renouardi, is 1.80 mm tall and is named after the French caver, Louis Renouard, who explored and mapped the only two caves in Laos known to harbor this group of tiny snails. Only two species of Laoennea snail are known so far, L. carychioides and now, L. renouardi

Caver and scientist, Dr. Adrienne Jochum, affiliated with the Natural History Museum Bern and University of Bern (Switzerland), as well as the Senckenberg Research Institute and Natural History Museum (Frankfurt, Germany) described the new species and its cave habitat together with co-authors: Estée Bochud, Natural History Museum Bern; Quentin Wackenheim, Laboratoire de Géographie Physique (Meudon, France) and Laboratoire Trajectoires (Nanterre, France); Marina Ferrand, EEGC; and Dr. Adrien Favre, Senckenberg Research Institute and Natural History Museum, in the open-access, peer-reviewed journal Subterranean Biology.

“The discovery and description of biodiversity before it disappears is a major priority for biologists worldwide. The caves in Laos are still largely underexplored and the snails known from them remain few in number,”

points out Dr. Jochum. 

The fact that two species of tiny cave snails of the same group were found in two caves located in two independent karstic networks 3.4 km apart, caused the authors to question evolutionary processes in these underground hotspots of biodiversity. The authors hypothesise that the two caves might have been connected during the Quaternary, around 100–200 thousand years ago. In time, the river Yè might have formed a barrier, thus disconnecting the cave systems and separating the populations. As a result, the snails evolved into two different species.

Death from below: the first video of a parasitic wasp attacking caterpillar underwater

Named after fictional monster Godzilla, a parasitic wasp becomes the first observed and filmed to dive underwater for several seconds, in order to attack and pull out caterpillar hosts, so that it can lay its eggs inside them before releasing them back in the water.

A very few species of parasitoid wasps can be considered aquatic. Less than 0.1% of the species we know today have been found to enter the water, while searching for potential hosts or living as endoparasitoids inside of aquatic hosts during their larval stage.

Within the subfamily Microgastrinae (family Braconidae), only two species have previously been recorded to be aquatic, based on their parasitism of aquatic caterpillars of moths. However, none has been known to actually dive in the water.

Recently, during their research work in Japan, Dr. Jose Fernandez-Triana of the Canadian National Collection of Insects and his team found and recorded on camera the first microgastrine parasitoid wasp that dives underwater for several seconds, in order to attack and pull out caterpillar hosts, so that it can lay its eggs inside them before releasing them back in the water.

Interestingly, the wasp, which was described as a new to science species in the open-access, peer-reviewed scientific Journal of Hymenoptera Research, was given the awe-striking name Microgaster godzilla, because its emergence out of the water reminded the scientists of the Japanese iconic fictional monster Godzilla.

In the video, the female wasp can be seen walking over floating plants as it searches for hosts, specifically larvae of the moth species Elophila turbata, which constructs a portable case from fragments of aquatic plants and lives inside it near the water surface. Once the wasp finds one of those cases, it first probes it repeatedly with its antennae, while moving around. Eventually, it forces the larvae to come out of the case and parasitizes it by quickly inserting its ovipositor. In some cases, the wasp has to submerge completely underwater for several seconds, in order to find and pull the caterpillar out of its case. To do this, the species has evolved enlarged and strongly curved tarsal claws, which are thought to be used to grip the substrate as it enters the water and looks for hosts.

A female wasp Microgaster godzilla seeks out a moth caterpillar, dives in the water and pulls it out of its case, in order to parasitize it by quickly inserting its ovipositor.
Video by Dr. Jose Fernandez-Triana

As for the curious choice of name for the new species, Dr. Jose Fernandez-Triana explains:

“The reasons why we decided to use the name of Godzilla for the wasp species are interesting. First, being a Japanese species, it respectfully honours Godzilla (Japanese: ゴジラ, Hepburn: Gōjira), a fictional monster (kaiju) that became an icon after the 1954 Japanese film of the same name and many remakes afterwards. It has become one of the most recognizable symbols of Japanese popular culture worldwide. Second, the wasp’s parasitization behaviour bears some loose resemblance to the kaiju character, in the sense that the wasp suddenly emerges from the water to parasitize the host, similar to how Godzilla suddenly emerges from the water in the movies. Third, Godzilla has sometimes been associated, albeit in different ways, with Mothra (Japanese: モスラ, Hepburn: Mosura), another kaiju that is typically portrayed as a larva (caterpillar) or an adult moth. As you can see, we had biological, behavioural and cultural reasons to justify our choice of a name. Of course, that and having a bit of fun, because that is also an important part of life and science!”

Beyond unusual behaviours and funny names, Dr. Fernandez-Triana wants to emphasize the importance of multidisciplinary work and collaboration. The team that published this paper got to know each other at an international meeting devoted to biological control (The 5th International Entomophagous Insects Conference in Kyoto, Japan, 2017). 

“I was very impressed by several presentations by Japanese grad students, which included video recordings of parasitoid wasp biology. As a taxonomist, I am always impressed with the quality of research done by colleagues in other fields. In this case, we saw an opportunity to combine our efforts to study the wasp in detail and, when we found that it was a new species, we described it together, including adding the filmed behaviour to the original description. Usually, taxonomic descriptions of parasitoid wasps are based on dead specimens, with very few details–often none–on its biology. Thanks to my biocontrol colleagues, we could add more information to what is known about the new species being described. Hopefully we can continue this collaboration and combined approach for future studies”.

Over a century later, the mystery of the Alfred Wallace’s butterfly is solved

An over a century-long mystery has been surrounding the Taiwanese butterfly fauna ever since the “father of zoogeography” Alfred Russel Wallace described a new species of butterfly: Lycaena nisa, whose identity was only re-examined in a recent project looking into the butterflies of Taiwan. Based on the original specimens, in addition to newly collected ones, Dr Yu-Feng Hsu of the National Taiwan Normal University resurrected the species name and added two new synonyms to it.

Described by the “father of zoogeography” and co-author of the theories of evolution and natural selection, the species hasn’t been reexamined since 1866

An over a century-long mystery has been surrounding the Taiwanese butterfly fauna ever since the “father of zoogeography” Alfred Russel Wallace, in collaboration with Frederic Moore, authored a landmark paper in 1866: the first to study the lepidopterans of the island. 

Back then, in their study, Moore dealt with the moths portion and Wallace investigated the butterflies. Together, they reported 139 species, comprising 93 nocturnal 46 diurnal species, respectively. Of the latter, five species were described as new to science. Even though the correct placements of four out of those five butterflies in question have been verified a number of times since 1886, one of those butterflies: Lycaena nisa, would never be re-examined until very recently. 

In a modern-day research project on Taiwanese butterflies, scientists retrieved the original type specimen from the Wallace collection at The History Museum of London, UK. Having also examined historical specimens housed at the Taiwan Agricultural Research Institute, in addition to newly collected butterflies from Australia and Hong Kong, Dr Yu-Feng Hsu of the National Taiwan Normal University finally resolved the identity of the mysterious Alfred Wallace’s butterfly: it is now going by the name Famegana nisa (comb. nov.), while two other species names (Lycaena alsulus and Zizeeria alsulus eggletoni) were proven to have been coined for the same butterfly after the original description by Wallace. Thereby, the latter two are both synonymised with Famegana nisa.

Despite having made entomologists scratch their heads for over a century, in the wild, the Wallace’s butterfly is good at standing out. As long as one knows what else lives in the open grassy habitats around, of course. Commonly known as ‘Grass Blue’, ‘Small Grass Blue’ or ‘Black-spotted Grass Blue’, the butterfly can be easily distinguished amongst the other local species by its uniformly grayish white undersides of the wings, combined with obscure submarginal bands and a single prominent black spot on the hindwing. 

However, the species demonstrates high seasonal variability, meaning that individuals reared in the dry season have a reduced black spot, darker ground colour on wing undersides and more distinct submarginal bands in comparison to specimens from the wet season. This is why Dr Yu-Feng Hsu notes that it’s perhaps unnecessary to split the species into subspecies even though there have been up to four already recognised.

***

Alfred Russel Wallace, a British naturalist, explorer, geographer, anthropologist, biologist and illustrator, was a contemporary of Charles Darwin, and also worked on the debates within evolutionary theory, including natural selection. He also authored the famed book Darwinism in 1889, which explained and defended natural selection. 

While Darwin and Wallace did exchange ideas, often challenging each other’s conclusions, they worked out the idea of natural selection each on their own. In his part, Wallace insisted that there was indeed a strong reason why a certain species would evolve. Unlike Darwin, Wallace argued that rather than a random natural process, evolution was occurring to maintain a species’ fitness to the specificity of its environment. Wallace was also one of the first prominent scientists to voice concerns about the environmental impact of human activity.

The birdcatcher trees – genus Pisonia – are infamous for trapping birds with their super-sticky seed pods that would frequently entangle the body of the ‘victim’. Left flightless, the poor feathered creatures eventually die either from starvation or fatigue, or predators. Similarly notorious are the birdcatcher trees for botanists, who have been baffled by their complicated classification for the last three centuries. 

Here’s why myself and graduate student Elson Felipe Rossetto of the Universidade Estadual de Londrina (Brazil) decided to take up the untangling of this issue with our recent taxonomic studies. You can find our research paper published in the open-access scholarly journal PhytoKeys.

We reestablished two genera: Ceodes and Rockia, where both had been previously merged under the name of Pisonia. Now, as a result, there are three distinct lineages of birdcatcher trees from the islands of the Pacific and Indian Oceans: Ceodes, Pisonia, and Rockia.

“Previous molecular studies on Pisonia species from around the world showed that species were clustered into three major groups, and here we assign names for each of them. With this new classification, a large number of the species known as Pisonia will be henceforth named Ceodes. This includes the Parapara (Ceodes brunoniana) and the Birdlime (Ceodes umbellifera) trees, both native to many islands, including Hawaii and New Zealand. They are commonly planted in gardens for their lush and sometimes variegated foliage, as well as their fragrant white flowers. However, the Cabbage tree (Pisonia grandis) will still be technically known as Pisonia.”

adds the study’s lead author Felipe Rossetto.

Birdcatcher trees have generated much controversy in the popular media because of their seed pods (technically called “anthocarps”) secreting a sticky substance that glues them to the feathers of seabirds or other animals for dispersal. Sometimes, though, too many seed pods can harm or kill birds, especially small ones, by weighing them down and rendering them flightless. This macabre practice has led to many controversies and local campaigns aiming to remove the trees, even illegally.

In spite of their forbidding reputation, however, we would like to stress that birdcatcher trees have positive effects on ecosystems and are important components of vegetation, especially for small islands. Sadly, there are many endemic and already endangered species of birdcatcher trees that only exist on a few small islands, where they are effectively placed at the mercy of local people.

Many species of birdcatcher trees are large and, thereby, tolerate harsh environments like seafronts and rocky cliffs, making them prime nesting spots for seabirds. Birdcatcher trees are also ecologically curious and could be regarded as keystone species in small islands, because their soft branches can sustain many types of invertebrates; their flowers are an important food source for bees and ants; their dense leaf litter nourishes the soil; and their roots have intimate interaction with native underground fungi (mycorrhiza).

All in all, clarifying the taxonomy of the birdcatcher trees is the first step to understanding how many species exist and how they relate to each other. 

Although most people relate birdcatcher trees with beaches and coastal habitats, there are species that are only found in mountains or rainforests. For example, the species now allocated to the genus Rockia is endemic to the Hawaiian archipelago. These are small trees able to grow in dry to mesic mountain forests. Using our new classification, future studies can explore in detail the hidden diversity of these enigmatic plants, and find out how trees with high dispersal capabilities evolve into species endemic to small island ecosystems.

Shining like a diamond: a new species of diamond frog from northern Madagascar

Despite the active ongoing taxonomic progress on the Madagascar frogs, the amphibian inventory of this hyper-diverse island is still very far from being complete. More new species are constantly being discovered, often within already well-studied areas. So, in one of the relatively well-studied parks in northern Madagascar, a new species of diamond frog, Rhombophryne ellae, was found in 2017. Now, the discovery is published in the open-access journal Zoosystematics and Evolution.

Despite the active ongoing taxonomic progress on Madagascar’s frogs, the amphibian inventory of this hyper-diverse island is still very far from being complete. The known diversity of the diamond frog genus Rhombophryne in Madagascar has increased significantly (more than doubled!) over the last 10 years, but still there are several undescribed candidate species awaiting description. New species are constantly being discovered in Madagascar, often even within already well-studied areas. One such place is the Montagne d’Ambre National Park in northern Madagascar.

Montagne d’Ambre National Park is widely known for its endemic flora and fauna, waterfalls and crater lakes, and considered to be a relatively well-studied area. Yet, only two studies have been published so far on the reptiles and amphibians of the Park.

Rhombophryne ellae was captured just as Cyclone Ava began to make itself felt across Madagascar with high winds and heavy rain. The camp where Dr. Scherz and his team were based became flooded, with rivers running through the kitchen and sleeping area. Miserable weather for humans, but a time of increased activity for some of the more elusive amphibians of the forest.

Serving the pursuit of knowledge of the herpetofauna in the region, Germany-based herpetologist Dr. Mark D. Scherz (Bavarian State Collection of Zoology, Technical University of Braunschweig, University of Konstanz) published a description of a new diamond frog species: Rhombophryne ellae, in the open-access journal Zoosystematics and Evolution.

“As soon as I saw this frog, I knew it was a new species. The orange flash-markings on the legs and the large black spots on the hip made it immediately obvious to me. During my Master’s and PhD research, I studied this genus and described several species, and there are no described species with such orange legs, and only few species have these black markings on the hip. It’s rare that we find a frog and are immediately able to recognise that it is a new species without having to wait for the DNA sequence results to come back, so this was elating”,

shares Dr. Scherz.

The new species is most closely related to a poorly-known and still undescribed species from Tsaratanana in northern Madagascar, but is otherwise quite different from all other diamond frogs. With the orange colouration on its legs, Rhombophryne ellae joins the growing list of frogs that have red to orange flash-markings. The function of this striking colouration remains unknown, despite having evolved repeatedly in frogs, including numerous times in Madagascar’s narrow-mouthed frogs alone.

“The discovery of such a distinctive species within a comparatively well-studied park points towards the gaps in our knowledge of the amphibians of the tropics. It also highlights the role that bad weather, especially cyclones, can play in bringing otherwise hidden frogs out of hiding—Rhombophryne ellae was caught just as Cyclone Ava was moving in on Madagascar, and several other species my colleagues and I have recently described were also caught under similar cyclonic conditions”,

says Dr. Scherz.

The species is known so far only from a single specimen, making it difficult to estimate its conservation status. Yet, based on the status of other, related frogs from the same area, it will probably be Red-listed as Near Threatened due to its presumably small range and micro-endemicity.

A new character for Pokémon? Novel endemic dogfish shark species discovered from Japan

A new endemic deep-water dogfish shark: Squalus shiraii, was discovered in the tropical waters of Southern Japan by an international team of scientists led by Dr. Sarah Viana from South African Institute for Aquatic Biodiversity. The finding brings the amount of spurdogs shark species inhabiting Japanese waters to six. The discovery is published in the open-access journal Zoosystematics and Evolution.

Newly discovered creatures can often be as impressive and exciting as the ones from the Japanese movies and shows. Many of those fictional characters, including inhabitants of the famous Pokémon universe, might have their analogues among the real animals native to Japan. Maybe, a new species of the dogfish shark published in the open-access journal Zoosystematics and Evolution is also “a real Pokémon” to be?

The new shark has the body length of 59-77 cm and some unique characteristics such as tall first dorsal fin and caudal fin with broad white margins. Currently, the species is known exclusively as a Japanese endemic, occurring in the tropical shallow waters of Southern Japan in the North-western Pacific.

Spurdogs represent commercially important for the world fish trade taxa. They are caught for a range of purposes: consumption of meat, fins and liver oil. Despite their high occurrence, the accurate identification data of species is scarce, population threats and trends remain unknown.

Japan currently represents one of the world’s leading shark fish trade countries, though, during the last decades the amount of shark catches is decreasing and over 78 elasmobranch species traded in Japanese shark fin markets are now evaluated as threatened.

The new species Squalus shiraii previously used to be massively misidentified with shortspine spurdog, due to the resembling shape of body, fins and snout length. However, there are some differences, defining the specificity of the new species.

Squalus shiraii has body brown in colour, postventral and preventral caudal margins whitish, dorsal and ventral caudal tips broadly white and black upper caudal blotch evident in adults. S. mitsukurii has body conspicuously black to dark grey and caudal fins black throughout with post-ventral caudal margin fairly whitish and black upper caudal blotch not evident in adults”, shares lead author Dr. Viana.

Scientists propose the name for the newly described species as Shirai’s spurdog in honour to Dr. Shigeru Shirai, the former Japanese expert of the group.

The Commission on Zoological Nomenclature proposes amendments to its Constitution

The ICZN Commissioners (Singapore, 2019)

The International Commission on Zoological Nomenclature (ICZN) proposes amendments to its Constitution – the legal basis determining how the Commission is to be governed – to solicit feedback from the zoological community, who will have one year, starting 30 April 2020, to submit constructive comments before the Commissioners cast their votes. To prompt useful debate on the revision of the foundational rules and principles at the ICZN, these comments will be openly published in the Bulletin of Zoological Nomenclature and the ICZN website. 

In compliance with the ICZN Constitution, the proposed amendments are now available in the Bulletin of Zoological Nomenclature (BZN) and three other suitable journals, including the peer-reviewed open-access journal ZooKeys. Given there is a sufficient consensus on the proposed amendments, the final version of the Constitution will be presented to the International Union of Biological Sciences for provisional ratification. Afterwards, the decision and date of effective ratification will also be published in BZN.

Established in 1895, the ICZN is an organisation, whose task is to act as the adviser and arbiter for the zoological community by generating and disseminating information on the correct formation and use of the scientific names of animals. The ICZN is responsible for producing the International Code of Zoological Nomenclature, which is a set of rules for the naming of animals and the resolution of nomenclatural problems.

Key proposed amendments address the terms of service and eligibility of members of the Commission; the inclusion of the ICZN website as a primary venue for information dissemination; reducing the standard voting period from three months to two, in recognition of the faster transmission speed of electronic mail compared to postal mail; and adding the maintenance of ZooBank – the Official Register of Zoological Nomenclature – to the list of responsibilities of the Commission.

“Along with recent amendments to its Bylaws, the proposed amendments to the ICZN Constitution will help the Commission to fulfil its aim of promoting stability and universality in the nomenclature of animals,”


comment from the ICZN.

Latest results of myriapod research from the 18th International Congress of Myriapodology

Last year, the 18th International Congress of Myriapodology brought together 92 of the world’s top experts on the curious, yet still largely unknown multi-legged centipedes, millipedes, pauropods, symphylans (collectively referred to as myriapods) and velvet worms (onychophorans).

Held between 25th and 31st August 2019 at the Hungarian Natural History Museum in Budapest and co-organised by the Hungarian Biological Society, the biennial event saw the announcement of the latest findings related to the diversity, distribution and biology of these creatures. Now, the public gets the chance to learn about a good part of the research presented there on the pages of the open-access scholarly journal ZooKeys.

The special issue in ZooKeys, “Proceedings of the 18th International Congress of Myriapodology (25-31 August 2019, Budapest, Hungary)“, features a total of 11 research articles reporting on species new to science, updates on the distribution and conservation of already known myriapods and discoveries about the biology, ecology and evolution of individual species. Together, the publications reveal new insights into the myriapod life on four continents: Europe, Asia, Africa and Australia.

Amongst the published research outputs worth mentioning is the comparison between regional and global Red Listings of Threatened Species that worryingly identifies a missing overlap between the myriapod species included in the global IUCN Red List and the regional ones. This first-of-its-kind overview of the current conservation statuses of myriapods from around the world highlights the lack of dedicated funding for the conservation of hundreds of threatened myriapods. As a result, the scientists behind the study urge for the establishment of a Myriapoda Specialist Group in the Species Survival Commission of the IUCN.

Meanwhile, to give us a hint about how many millipedes are out there unbeknownst to the world and any conservation authorities, at the congress, three research teams revealed a total of seven new to science species: three giant pill-millipedes from Vietnam, another three from the biodiversity hotspot Madagascar and a spirostreptid millipede inhabiting Sao Tome and Principe.

Amongst the rest of the papers is the curious discovery of two Tasmanian species of flat-backed millipedes of the genus Tasmaniosoma whose neighbouring populations have seemingly come to their own terms to keep distance between each other, save for a little stretch of land, for no obvious reason. Not a single site where both species occur together was found by Dr Bob Mesibov, the millipede expert behind the study. How is the parapatric boundary maintained? How, when and where did the parapatry originate? These are the big mysteries that the already retired Australian scientist leaves for his successors to resolve.
