Of Star Trek, Mark Twain and helmets: 15 new species of wasps with curious names

A total of fifteen new species of parasitic wasps have been described from across the Neotropical region. Apart from belonging to a peculiar group of wasps distinct with large and elongated bodies, the new insects also draw attention with the curious names they have been formally assigned with.

Among them, there are species named after characters from the television series Star Trek and Mark Twain’s The Prince and the Pauper, and five wasps bearing species names all translating to ‘helmet’. The study, conducted by graduate student Katherine C. Nesheim and Dr. Norman F. Johnson, both affiliated with the Ohio State University, USA, and Dr. Lubomír Masner, Agriculture and Agri-Food Canada, is published in the open access journal ZooKeys.

The larvae of the studied wasps parasitise the eggs of lanternflies and planthoppers. These species inhabit exclusively the Neotropical region, with their range stretching from the Isthmus of Tehuantepec in the north to Misiones in southern Paraguay. Despite being quite abundant in the region, these insects have remained under-researched until recently.

One of the newly discovered wasp is named Phanuromyia odo, where the species name odo refers to the Star Trek: Deep Space Nine fictional character of the same name. In the popular sci-fi television series, Odo belongs to a species of shapeshifters called Changelings. The reason for the scientists to associate the parasitoid with the character is the spectacular variability observed within the insect species. In fact, it was this peculiarity that, at some point, led the entomologists believe they were dealing with two separate species.

The authors do not make a clear statement that the new species P. pauper has a name inspired by the famous novel The Prince and the Pauper by Mark Twain. Instead, they justify their choice with the fact that the species lacks a specific morphological feature – thus making it ‘poor’. On the other hand, the authors confirm that the new species called P. princeps is of ‘blue blood’ indeed, having its name derive from the other main character of the same book. Furthermore, both species are reported to look a lot like each other.

Among the curious names in the list of new species, there are also five wasps whose scientific names all translate to ‘helmet’ in three different languages – Greek, Latin and Old Norse. The reason behind is that they have unusually large heads, which reminded the scientists of a “knight wearing a helmet”. Likewise, a related species received a name that in Latin means ‘wearing a hood’.

There is also a species, whose name means ‘having long hair’, and another called ‘constellation’ in Latin.

The first crowdfunded study in Japan: Micro X-ray observation of a fleshy brittle star

Not only have scientists from Japan performed the first non-destructive morphological observations on the Fleshy brittle star, Asteronyx loveni, using micro X-ray tomography, but they also published their research as the first study supported via crowdfunding in the Asian country.

The team leader, Dr. Masanori Okanishi, Ibaraki University, managed to raise part of the funds via Japan’s pioneering crowd-funding platform academist. The study by Dr. Masanori Okanishi, Dr. Toshihiko Fujita, National Museum of Nature and Science, Tsukuba, Yu Maekawa and Dr. Takenori Sasaki, University of Tokyo, is now openly available in the open access journal ZooKeys.

While taxonomy is generally considered as “minor” and “basic” discipline within biology, it could be extremely strenuous for taxonomists to apply for and receive funding. Thus, Dr. Okanishi jumped to the conclusion that his planned study might have a go via crowdfunding instead.

Dr. Okanishi approached academist in April 2014, when he was a Postdoctoral researcher at Kyoto University. Titled “Taxonomy of bathyal euryalid ophiuroids”, it was not long before his research project successfully raised 634,500 JPY (ca. 5,600$).

Having already stumbled across several undescribed species of the brittle star genus Asteronyx, the scientists directed the raised funds towards the genetic and morphological analysis of Asteronyx loveni.

As suggested by its common name, the fleshy brittle star (Asteronyx loveni) is covered by thick skin, making it particularly difficult for scientists to observe the body in detail without dissolving the skin. However, modern computed tomography with micrometer resolution allowed for the 3D images of skeletal ossicles and soft tissues to be constructed with no physical intervention whatsoever.

“The present case indicates that crowdfunding will increase the chances to finance the funds for researchers in those disciplines and activate the research area,” conclude the authors.

The newly discovered brittle star species are yet to be published.

The Cerberus Groundsnake is a Critically Endangered new species from Ecuador

With as many as 140 species, Atractus is the most diverse snake genus in the world, even though it can be found exclusively in Central and South America. However, these colubrid ground snakes seem largely under-researched, since there have been thirty-three species discovered in the last ten years only.

As concluded by a team of scientists, led by Alejandro Arteaga, Tropical Herping, Ecuador, this is the result of a lack of DNA information in the original descriptions of many of these species. Consequently, there have been a lot of specimens sitting in museum collection that remain either misidentified, or anonymous.

To address the issue around the problematic identification of these snakes and their correct placement in the tree of life, the scientists have studied the hereditary molecular differences in the genus using both newly collected specimens, as well as previous publications on the species occurring in the Pacific lowlands and the adjacent Andean slopes.

Their research results in a new paper, published in the open access journal ZooKeys, which describes a total of three new species from Ecuador. The authors also propose a new species group and a redefinition of a previously established one.

Interestingly, one of the new species is to be referred to as Cerberus Groundsnake, while in the books it will appear under Atractus cerberus. It is predominantly brown in colour with faint black longitudinal bands, and measures about 21 – 31 cm in length. The biologists justify the curious name of this species with the peculiar location where they spotted the first known specimen. Found at the gates of the newly formed “Refinería del Pacífico”, a massive industrial oil-processing plant, the authors were quick to recall the multi-headed monstrous dog Cerberus, known to be guarding the gates of the underworld, according to Greek mythology.

In terms of their conservation status, the scientists have proposed the Cerberus Groundsnake to be listed as Critically Endangered, according to the IUCN criteria, since its single known habitat is highly likely to be the only one, being isolated from any other similar habitats. Moreover, it comprises a relatively small patch of land, which in turn is declining in both size and quality due to deforestation. According to the IUCN criteria, a Critically Endangered status is given to a (group of) species whenever the best available evidence indicates that it faces an extremely high risk of extinction in the wild.

The other two new species, the Indistinct (Atractus esepe) and the Pyron’s (Atractus pyroni) ground snakes are to be listed as Data Deficient as the information about them is currently insufficient for their risk of extinction to be assessed.

Having increased the number of Atractus species in Ecuador to twenty-seven, the authors expect that the count is yet to rise. “We hope that the novel genetic and morphological data provided herein will promote future researchers to examine species boundaries in Atractus, as additional work clearly is waiting,” they add.

A new species of hard coral from the World Heritage-listed Lord Howe Island, Australia

The discovery of a new species of hard coral, found on Lord Howe Island, suggests that the fauna of this isolated location in the Tasman Sea off south eastern Australia is even more distinct than previously recognised.

In a recent paper in ZooKeys, Prof. Andrew Baird and Dr. Mia Hoogenboom from James Cook University, Townsville Australia and Dr. Danwei Huang from the National University of Singapore, describe the new species Cyphastrea salae.

“The animal itself is quite non-descript from a distance, although it is beautifully symmetrical up close like most corals,” says Dr. Hoogenboom. “But we believe this is the first of many new hard coral species to be found in this World Heritage-listed marine protected area.”

Lord Howe Island is famous for its many unique plant and animal species, known from nowhere else on Earth, including at least four species of palms, nine reef fish and 47 algae. However, the coral fauna remains largely unexplored, particularly using modern genetic techniques.

While some of the earliest work on coral reef ecology was done on Lord Howe Island, the species lists were compiled using a morphological taxonomy that has since been revised.

“On my very first dive in the lagoon at Lord Howe I knew I was looking at something very special,” says Prof. Baird. “Twenty years of diving all over the globe had not prepared me for what I saw. I could hardly put a name on any coral!”

Now, six years later, and largely due to the molecular skills of colleague Dr. Huang, the team is ready to name its first species.

“Interestingly, Cyphastrea salae looks almost exactly like other closely-related corals. However, its gene sequences are distinct and there is no doubt it is a species that is new to science,” says Dr. Huang.

The team now have hundreds of specimens to work through, but they are confident that there are more new coral species left to describe.

“The Acropora, in particular, look highly promisingly,” says Prof. Baird. “There are at least five species that look unlike anything I have seen anywhere else in my travels”.

Lord Howe Island lies over 900 km south of the next major area of coral diversity, the Great Barrier Reef, and therefore the populations on Lord Howe are highly isolated. Such isolation creates the potential for speciation, however, C. salae is the first new local coral species described to date. The discovery of this new species greatly increases the conservation significance of Lord Howe Island and reinforces the need for strong management measures to protect this unique fauna.

New species of terrestrial crab found climbing on trees in Hong Kong

A new species of terrestrial crab has been found to climb trees on the eastern coast of Hong Kong. All specimens spotted during the survey have been collected at a height of approximately 1.5 – 1.8 m, walking on the bark of the branches at ebbing and low tides. The species is described in the open access journal ZooKeys.

Among the crab’s characteristic traits are squarish predominantly dark brown carapace, very long legs and orange chelipeds. The species is less than a centimetre long, with the studied specimens measuring between 8 and 9 millimetres, irrespective of their sex. However, the chelipeds of the males appear stout, while in females they are distinctly more slender.

The scientists who found the new species (Haberma tingkok), Dr. Stefano Cannicci, the Swire Institute of Marine Science at the University of Hong Kong, and Dr. Peter Ng, National University of Singapore, have placed the new species in a small genus, which now contains merely three species. In fact, Dr. Peter Ng has been involved in the discovery of all of them. He also led the team that established the genus 15 years ago, having collected a small previously undescribed species of mangrove crab from Singapore.

The discovery of the tiny crustacean once again proves how little is known about the diversity of these crabs in Hong Kong. Furthermore, the mangroves that make for the habitat of the new species are under severe impact by both pollution and land reclamation, which underlines the urgent need for their conservation.

Earlier this year, Dr. Peter Ng teamed up with Dr. Jose Christopher Mendoza to describe another new species of crab, collected from the rubble at the island of Guam and named after two of the main characters in J. K. Rowling’s Harry Potter fantasy series.

With flying colors: Top entomology students honoured with wasp species named after them

The highly divergent parasitic wasps have long been causing headaches to scientists. At one point, taxonomists began using some genera as “dumping grounds for unplaced members”, simply to organise the species.

Two entomologists from the University of Kentucky, USA – Drs. Michael J. Sharkey and Eric Chapman, have recently addressed one such issue by describing ten new genera and many more new species and combinations. The resulting paper is published in the open access journal ZooKeys.

Interestingly, among the newly described species there are two wasps named after two excellent entomology students: Leuroagathis paulbakeri and Scabagathis emilynadeauae. Both Mr. Paul Baker and Ms. Emily Nadeau scored 100% during an Entomology class in 2015. Paul passed the written exam with flying colours, while Emily did best on the weekly quizzes.

One of the new genera (Chimaeragathis) is named after the Greek mythological monster Chimera. Known as the sibling of the infamous Cerberus and Hydra, the Hellenes would describe Chimera as a horrid hybrid comprising several animals – usually a lion, a goat, and a serpent. The scientists have picked this name as a reference to the multiple diagnostic characters of the genus. In turn, each of those characters consists of a set of features used to diagnose related genera.

To breed, the females of these wasps lay eggs inside the early stages of caterpillars of various moths. At first, the larva develops quietly as if unnoticed by the host. By the time the caterpillar is ready to spin a cocoon, the parasitoid ‘awakes’ and consumes the host from the inside.

The aim of the present study is to revise the representatives of a tribe of braconid parasitoid wasps inhabiting Southeast Asia with a focus on Thailand. While having described a lot of new taxa, the scientists have saved another batch of new species for a separate future paper.

New frog from the Peruvian Andes is the first amphibian named after Sir David Attenborough

While there are already a number of species named after famous British broadcaster and naturalist Sir David Attenborough, including mammals, reptiles, invertebrates and plants, both extinct and extant, not until now has the host of the BBC Natural History’s Life series been honoured with an amphibian.

A new fleshbelly frog, recently discovered in the Peruvian Andes, is formally described as Pristimantis attenboroughi, while commonly it is to be referred to as the Attenborough’s Rubber Frog. The new species is published in the open-access journal ZooKeys.

Scientists Dr. Edgar Lehr, Illinois Wesleyan University, and Dr. Rudolf von May, University of Michigan, spent two years (2012-2014) surveying montane forests in central Peru, in order to document the local amphibians and reptiles, and evaluate their conservation statuses. Their efforts have been rewarded with several new species of frogs and a new spectacled lizard.

Each of these discoveries, including the Attenborough’s Rubber Frog, prove how beneficial it is to take into account both morphological and the genetic data, while looking for species new to science. For example, the authors report that when they spotted the P. attenboroughi frog for the first time, both of them were sure that they had found a species of another genus.

The Attenborough’s rubber frog is known to inhabit several localities across the Pui Pui Protected Forest, a nature reserve located at elevations between 3400 and 3936 m a.s.l. in central Peru. The adult males reach size of 14.6-19.2 mm in length, while the females are larger measuring between 19.2 and 23.0 mm. Their ground colour ranges from pale to dark gray, or reddish brown to brownish olive with dark gray scattered flecks. Meanwhile, the juveniles are paler (yellowish to reddish brown) with contrasting dark brown flecks and distinct stripes.

Due to the amphibian being known from fewer than ten localities, spread across less than 20,000 km2, the species should be deemed either Vulnerable or Endangered, according to the IUCN Red List Categories and Criteria. However, the authors suggest that the Attenborough’s Rubber frog should be listed as Near Threatened instead, since the Piu Piu forest is formally protected and still largely unknown, so it is likely that there are more additional populations of the new species. On the other hand, factors such as fungal infections, climate change, pollution, and man-made fires continue to be threats for many Andean amphibians even inside protected areas.

“We dedicate this species to Sir David Frederick Attenborough in honor for his educational documentaries on wildlife, especially on amphibians (e.g., Life in Cold Blood, Fabulous Frogs), and for raising awareness about the importance of wildlife conservation,” explain the authors.

In the present study, the scientists note that there are more terrestrial-breeding frogs from the surveyed montane forests that will be described in the near future.

Among the numerous namesakes of Sir David Attenborough to date, there are a rare genus of beautiful flowering plants, a rare butterfly species, commonly known as the Attenborough’s black-eyed satyr, a flightless weevil species, as well as a number of extinct species.

Bird spiders detectives: The solution to a 200-year-old hairy mystery

Three species and three genera of birdeater spiders are described as new to science in a paper recently published in the open access journal ZooKeys. In their study, the Brazilian spider experts, Drs. Caroline Fukushima and Rogério Bertani, Laboratory of Ecology and Evolution, Instituto Butantan, report the diversity of the oldest tarantula genus (Avicularia), whose name derives from a famous 18th-century illustration depicting a bird caught by a spider.

Even though these harmless tarantulas have long been a favourite exotic pet around the world, their identity has remained problematic ever since the first species was described back in 1758 by the “father of modern taxonomy”, Carl Linnaeus.

“He described the species based on a hodgepodge of spiders,” explain the authors. “Over the next centuries, other species with completely different characteristics were called Avicularia creating a huge mess.” As a result, basic questions, such as the characteristic traits of the genus, the number of its species and their localities, have been left unanswered.

To address the confusion, the team studied both newly collected specimens and also specimens from around the world which had previously been deposited in museum collections. Thus, they concluded that, instead of the 49 species previously assigned to the problematic genus, there are in fact only 12, including three new to science.

One of the new species, Avicularia merianae, is named after Maria Sybilla Merian (1647-1717), a pioneering scientist and a remarkable artist who made the famous illustration of a spider eating a bird. In fact, it was her work that gave birth to the popular name used for a whole group of spiders, also known as birdeaters or bird spiders.

Meanwhile, the name of the new genus Ybyrapora, which occurs in the Brazilian Atlantic rainforest, translates to “those that live in trees” from the indigenous local language Tupi. It refers to the arboreal habitat of these species. The other two tarantula genera live exclusively on the Caribbean Islands.

“People think all biologists are like Indiana Jones, with their daily lives full of adventures in the wild. But most of the time, they are much more like Sherlock Holmes – sitting on a chair, collecting and analysing clues (specimens and scientific papers) and then using logical reasoning to solve Nature’s mysteries,” comments Dr. Caroline Fukushima.

“We, taxonomists, are ‘wildlife detectives’ who play an essential role not only in biology and conservation. Our work can also become the grounds for new technologies, medicines and ideas that could solve a variety of problems,” she adds.

“We are delighted to have finally closed one of the oldest unsolved cases,” the authors conclude.

New species of parasitic wasp discovered in the eggs of leaf-rolling weevils in Africa

A new species of parasitic wasp has been obtained from the eggs of weevils, associated with bushwillows, collected and identified by Dr. Silvano Biondi. Given the tiny insect from northeastern Gabon is the first record of its genus for West-Central Africa, the researchers Dr. Stefania Laudonia and Dr. Gennaro Viggiani, both affiliated with Italy’s University of Naples Federico II, decided to celebrate it by assigning the species a name that refers to the continent. Their team has published the findings in the open access journal ZooKeys.

Named Poropoea africana, the new species belongs to a large worldwide group of wasps well-known as egg parasitoids of leaf-rolling weevils. Using characteristically long ovipositors, they lay their own eggs in the eggs of the hosts, found in cigar-like rolls.

The new wasp measures less than 2 mm. It can be distinguished from related species by a number of characters, including the structure of the antennae, and the front and hind legs, which are more robust than the middle ones. The latter, which is a unique trait for the genus, seems to be an adaptation to host parasitisation, where the modified legs likely support the body and improve the propulsive efficiency of the ovipositor.

Moth gift: Winner of an eBay auction thanks his mother by naming a new species after her

The loving son presented the name to his mother on St. Valentine’s Day

Winner of an eBay auction Steve Mix received the opportunity to pick the name for a new species of satiny-white winged moth collected from the white gypsum dunes of the White Sands National Monument, New Mexico. A fan of butterflies and moths himself, he chose to honor his supportive and encouraging mother Delinda Mix, so the moth is now formally listed under the species name delindae. It is described in the open access journal ZooKeys.

Having spent 10 years studying the moth fauna at the White Sands National Monument, Eric H. Metzler, curator at the Michigan State University, but also research collaborator at the National Museum of Natural History, Smithsonian Institution, and research associate at the University of New Mexico and the University of Florida, discovered the moth during the first year of the study, in 2007. Back then, he spotted a curious small white moth with a satiny appearance, which immediately drew his attention.

Already assigned to the genus Givira to the family commonly known as carpenter millers, the moth was yet to be identified as a species. While most of its North American ‘relatives’ are either dark-colored, or have substantial dark smudges on the forewings, there are only four of them, including the new species, which are substantially white with few or no dark markings.

Further hindrance occurred when the researcher tried to study the specimens, as pinned moths turned out greased due to their abdomens being full of fatty tissue. However, the specialist managed to degrease them by carefully brushing their scales, and, having compared them to related species, confirmed them as representatives of a species new to science.

Then, Eric joined the fundraising event, organized by the Western National Parks Association (WNPA), a non-profit education partner of the US National Park Service. The highest bidder in the eBay auction would receive the chance to pick the scientific name for the satiny-looking moth, and thus, become part of history. Having won the opportunity, Steve Mix, who himself had once been interested in studying butterflies and moths, and has been maintaining his fondness of them ever since, decided to name the species after his mother Delinda Mix, in gratitude for “the support and encouragement she gave to her son”.

“Steve Mix submitted the winning bid, and he chose to have the moth named after his mother because of the lasting nature of this naming opportunity”, shares Eric. “I received no remuneration in this fundraising venture, and by volunteering my personal money, time, expertise, and experience I was able to help WNPA gain world-wide positive publicity while raising some much needed cash. The rewards to me were being able to help WNPA and Steve Mix honor his mother, which is just so very sentimental”.

“WNPA is so pleased that we were able to work with Eric and we are grateful to Steve. This project is a shining example of working together towards the common good of our parks with the added value of providing a priceless experience for everyone involved”, says Amy Reichgott, Development Manager at the Western National Parks Association.
