Behemoth in Leviathan’s crypt: Second Cryptomaster daddy longlegs species

Suggestively called Cryptomaster, the herein studied daddy longlegs genus, represented until recently by a single species, is not only difficult to find in the mountains of southwest Oregon, but had also stayed understudied for several decades since its establishment in 1969. Inspired by much newer records of the previously known species, called after the notorious Hebrew monster Leviathan, an American team of researchers from University of California Riverside and the San Diego State University, led by Dr. James Starrett, undertook a new search for mysterious endemic harvestmen, which was successfully concluded with the discovery of another beast, Cryptomaster behemoth. Their work is available in the open-access journal ZooKeys.

The Cryptomaster daddy longlegs belong in the largest and incredibly diverse harvestman suborder, called the Laniatores, which are characterized by having relatively short legs and preference for hiding underneath logs, stones and leaf litter in tropical and temperate forests. Typical for many of these well over four thousand species is that they might inhabit very restricted geographic regions and yet be strikingly genetically diverse. This is why when the authors understood about the recently expanded distributional range of the Leviathan’s namesake across different mountain ranges, they did not take long to assume that there could be more species having settled nearby.

Curiously, both Cryptomaster daddy longlegs species showed two forms of their species, a smaller and a larger one, but neither form was genetically different enough to suggest the presence of a separate group. The scientists observed the variation in both males and females from across both species and all their known localities.

Having its localities further increased as a result of the present study, C. leviathan shows surprisingly small genetic distance between its populations. In contrast, its sibling species is so far known to occupy far more restricted range, yet shows considerably more genetic variations.

Bearing the name of the huge notorious Hebrew monster Leviathan, the first member of the harvestman genus has won its name because of its excessive size when compared to its relatives within the family of travunioid daddy longlegs. Following the already established trend, the new species is called Cryptomaster behemoth after another large monster known from the Book of Job.

“This research highlights the importance of short-range endemic arachnids for understanding biodiversity and further reveals mountainous southern Oregon as a hotspot for endemic animal species,” point out the authors in conclusion.

A new species and genus of ‘horned necked’ praying mantis from a French museum collection

While studying the insect collection of the Museum national d’Histoire naturelle, Paris, France, two American scientists uncovered a small, leaf-dwelling praying mantis with unique features collected from Madagascar in 2001. Its distinctive “horned neck” and flattened, cone-like eyes, as well as the location from where it was found, led the researchers to assign the insect to a new genus and species. The study is published in the open-access journal ZooKeys.

Lead author Sydney Brannoch and co-author Dr. Gavin Svenson, both of the Cleveland Museum of Natural History and Case Western Reserve University, were working on a research project in their laboratory in Cleveland, Ohio, when Brannoch discovered the undescribed insect among the French collection on loan to them at the time. To determine the insect’s identity, the researchers first investigated the specimen’s locality, Tampolo, Madagascar, where it had been collected from the leaves of an unrecorded tree. When compared to other praying mantis species from this region, they found that this individual had many peculiarities that set it apart.

After comparing and analyzing specimens from various museums, the Cleveland scientists created a new genus for the praying mantis. They selected the genus name Cornucollis to reflect the horn-like projections, which extend from the insect’s neck. The team described and named the new mantis species Cornucollis masoalensis after the locality where the mantis was originally collected. It belongs to the subfamily Tropidomantinae, which is comprised of smaller, usually green mantises that appear to live on broad-leafed plants.

“Identifying a unique praying mantis hidden among other species was unexpected and exciting,” said lead author Sydney Brannoch, a Case Western Reserve University graduate student working under the direction of Dr. Gavin Svenson at the Cleveland Museum of Natural History. “There are untold numbers of species new to science sitting in cabinets and cases within natural history museums around the world. Often these specimens have been overlooked, in some cases for centuries. The discovery of this new praying mantis ultimately highlights the need for continued research in museum collections.”

“Museum collections hold hidden treasures of biodiversity,” said co-author Dr. Gavin Svenson, curator of invertebrate zoology at the Cleveland Museum of Natural History and adjunct assistant professor at Case Western Reserve University. “A closer look can reveal species never before recognized as unique.” Dr. Svenson supported the study as part of his ongoing research to classify praying mantises based on evolutionary relationships.

The newly described leaf-dwelling mantis, Cornucollis masoalensis, measures about 24 millimeters in length, which is small for a praying mantis. It has distinctive speckled patches on its head. The new mantis is pale in color with opaque, well-developed wings. Based on external appearance, the researchers believe that this species dwells on the undersides of leaves, a unique ecological niche occupied by morphologically similar, closely related species.

The scientists suggest further field surveys could provide science with additional knowledge about the new species and genus, including the description of a female individual.

This study was done as part of Dr. Svenson’s broader research project, which is focused on the evolutionary patterns of relationship, distribution, and complex features of praying mantises. His current research project aims to align new sources of relationship evidence (DNA sequence data) with morphology and other features to create a new and accurate classification system for praying mantises that reflects true evolutionary relationships.

Twenty-four new beetle species discovered in Australian rain forests

As many as twenty-four new species from Australian rainforests are added to the weevil genus Trigonopterus. Museum scientists Dr. Alexander Riedel, State Museum of Natural History Karlsruhe, Germany, and Rene Tanzler, Zoological State Collection Munich, Germany, have first discovered them among unidentified specimens in different beetle collections. The study is published in the open-access journal ZooKeys.

Australia is well known for its extensive deserts and savanna habitats. However, a great number of native Australian species are restricted to the wet tropical forests along the east coast of northern Queensland. These forests are also the home of the recent discoveries.

Most of the weevil species now recognised as new have already been collected in the 80s and 90s of the past century. Since then they had been resting in museum collections until German researcher Alexander Riedel had the opportunity to study them.

“Usually a delay of decades or even centuries occurs between the encounter of a new species in the field and its thorough scientific study and formal naming,” he explains. “This is due to the small number of experts who focus on species discovery,” he elaborates. “There are millions of unidentified insect specimens stored in collections around the world but only few people have the training necessary to identify those of special interest.”

However, old museum specimens alone are not enough either. Nowadays, researchers try to include DNA data in their descriptions, and the necessary sequencing techniques work more efficiently with freshly collected material. Therefore, the scientists set off to the field after they have studied the collections of others. Nevertheless, the German team were led to the discovery of one additional new species, which had never been seen before. They called itTrigonopterus garradungensis after the place where it was found.

All of the newly described weevils are restricted to small areas. Some are found only in a single locality. Presumably, this is a consequence of their winglessness, which has prevented them from spreading around. Furthermore, most of them dwell in the leaf litter where they are easily overlooked. Usually, they come to light during specific surveys of the litter fauna.

This is what Geoff Monteith from the Queensland Museum in Brisbane, for instance, has done in the past. As a result, his work is now relevant to conservation because highly localised species are extremely vulnerable to changes of their habitat such as climate change or the arrival of invasive species.

It is likely that Trigonopterus weevils have originated in Australia, the oldest landmass in the region. The island of New Guinea is geologically much younger, but there the genus has quickly enough diversified into hundreds of species. Studies investigating such evolutionary processes depend on names and clear diagnoses of the species. As a result of the present research, for the Australian fauna these are now available.

Besides the publication in the open-access journal ZooKeys, high-resolution photographs of each species are uploaded to the Species ID website, along with the scientific description. All this puts a face to the species name, and therefore is an important prerequisite for future studies on their evolution.

All Pensoft journals integrated with Publons to recognize your contribution as a reviewer

With both Pensoft and Publons aiming to facilitate scientific research and its introduction to the wide world, it only makes sense for the two to join efforts in a campaign to speed up publications, while giving the rightful credit to reviewers. From now on, anyone who makes this contribution to any of the 15 Pensoft journals will be able to opt-in to get credit for their peer reviews on Publons.

As for the moment, there are already 32 Pensoft reviewers who have added a total of 58 reviews to their Publons personal accounts and already started to receive recognition for their peer input – a kind of contribution that traditionally tends to be largely overlooked in academia. However, you can get a head start by signing-up to Publons and joining the 50,000 peer reviewers that are getting credit for their peer reviews.

Moreover, it is just as incredibly easy to add records of your Pensoft peer reviews to Publons thanks to the presently announced integration. It is while you are compiling your peer review for either Biodiversity Data Journal, BioRisk, Deutsche Entomologische Zeitschrift, Journal of Comparative Cytogenetics, Journal of Hymenoptera Research, MycoKeys, Nature ConservationNeoBiota, Nota Lepidopterologica, One Ecosystem, PhytoKeys, Research Ideas and Outcomes (RIO), Subterranean Biology, ZooKeys or Zoosystematics and Evolution journal, that you are asked whether you want to opt-in for the service. Then, once you have completed it, you are sent an email with a link to claim your review. To protect your anonymity, it is only the journal’s name and the year of the review that will be visible on your Publons profile.

The only exception to this rule is Pensoft’s next generation Research Ideas and Outcomes (RIO) journal, where the policy of ultimate transparency and openness requires all peer reviews and their authors to be made public. It is also the only Pensoft journal whose article titles will be available on a Publons profile by default. Another distinctive feature of RIO’s – an assigned DOI for each peer review, is also supported in Publons to ensure reviewers get the most out of their contribution.

“Pensoft has a strong history of innovation and we’re excited to be working together to reward the efforts of peer reviewers,” comments the new partnership Publons co-founder Andrew Preston. “It’s also great to see that many Pensoft editors are already Publons users.”

“Crediting reviewers’ voluntary contributions to the quality of scientific publications has always been a problem, especially with the current tremendous increase in the volume of published research outputs. We are happy that Publons has found such a solution and that we can credit our reviewers through recording their activity in an entirely automated way,” added founder and CEO of Pensoft Prof. Lyubomir Penev.

The lizard of consistency: New iguana species which sticks to its colors found in Chile

During a field trip at 3000 metres above sea level, a group of scientists, led by Jaime Troncoso-Palacios, Universidad de Chile, discovered a new endemic iguana species, in the mountains of central Chile, scientists. Noticeably different in size and scalation, compared to the rest of the local lizards, what initially grabbed the biologists’ attention was its colouration. Not only was it unlike the already described ones, but also appeared surprisingly consistent within the collected individuals, even regardless of their sex. Eventually, it was this peculiar uniformity that determined the lizard’s name L. uniformis. The study is published in the open-access journal ZooKeys.

The researchers found the lizards quite abundant in the area, which facilitated their observations and estimations. Apart from a thorough description of the new iguana along with its comparisons to its related species, the present paper also provides an in-depth discussion about the placement of the new taxon, which had been confused with other species in the past.

While most of the other lizards from the area and its surroundings often vary greatly in colouration and pattern between populations and sexes, such thing is not present in the new species. Both males and females from the observed collection have their bodies’ upper side in brown, varying from dark on the head, through coppery on the back and light brown on the tail. The down side of the body is mainly yellowish, while the belly – whitish. The only variables the scientists have noticed in their specimens are slight differences in the shade with two females demonstrating unusual olive hues on their snouts. These differences in morphology were also strongly supported by the molecular phylogeny through the analysis of mitochondrial DNA, which was performed by Dr. Alvaro A. Elorza, from Universidad Andres Bello.

Accustomed to life in highland rocky habitats with scarce greenery, these lizards spend their active hours, estimated to take place between 09:00 h and 18:00 h hidden under stones. However, they might not be too hard to find due to their size of about 8.5 cm for the males and their abundance in the studied area. The females are more slender and measure 7 cm in length on average.

Having caught one of their specimens while holding a yellow flower in its mouth, the scientists conducted further examination of the stomach contents of the studied individuals and concluded that the species is omnivorous, feeding mainly on plants as well as insects and roundworms.

In conclusion, the researchers showed that there is still a huge gap in the knowledge of the close relatives of the newly described species and their “challenging taxonomy”.

The tip of an iceberg: Four new fungus gnat species from the Scandinavian north

One may think that the extreme north of Europe is low in insect life, except for the notorious blood-sucking flies. However, while it is a generally accepted truth that both plant and animal species’ count is higher the closer one gets to the Equator, some insects display anomalous diversity gradient. Such is the case for European fungus gnats, for example, a highly diverse group of true flies. No less than about 1000 species are known to occur in the Scandinavian Peninsula, representing about 83% of the continent’s total. Furthermore, undescribed fly species are continuously being discovered from North Europe.

In a recent paper published in Biodiversity Data Journal, four new species are described. These species have been collected from mires and old-growth forests of Finnish Lapland between 2012 and 2014. One of the species has a wider range, known from Sweden, Norway and Canada.

‘I must admit that it was a pleasure to give names to these species’ says Dr. Jukka Salmela, conservation biologist at Parks & Wildlife Finland (Metsahallitus). ‘These four species are really interesting, because they are rather distant to other known members of the genus Boletina. I am also confident that these species are very rare and may be dependent on old-growth forests or small water bodies such as springs and wetlands.’

The names of the new species all reflect northern nature in one way or another. Boletina valteri is named after Professor Valter Keltikangas, a forest researcher who made very demanding and physically tough field excursions to Finnish Lapland in the 1920’s and the ’30’s.

Boletina kullervoi derives from Kalevala, a Finnish national epic. It tells the story of an orphan, called Kullervo, who eventually kills his foster father and commits suicide. The violent story of Kullervo has also inspired composer Jean Sibelius for his first symphony, “Kullervo”.

Boletina hyperborea is self-explanatory, meaning far north. The species occurs in Yukon and in northern Scandinavia. Similarly, Boletina nuortti is named after the River Nuortti. In north Sami language nuorti means east. The gorgeous and wild River Nuortti flows from Finland to Russia.

No less than 100 Fennoscandian (Scandinavian) fungus gnat species await their formal description. ‘The boreal and Arctic nature still holds many secrets. Entomologists with simple gear such as sweep nets, Malaise traps and microscopes can still make notable discoveries even in rather well-studied regions such as Finland and Sweden. Samples collected from northern mires and boreal forests are never boring if one studies neglected groups such as small flies,’ says Jukka Salmela. “These four newly described taxa just represent a small fraction of the numerous undescribed northern fly species, so they are like a tip of an iceberg.”

1,541 snout moth species and counting in the United States and Canada

The present snout moth list contains a ten-percent increase in the number of species since 1983. For the last thirty-three years snout moth specialists in the United States and Canada have been describing species new to science and recording species new to these two countries. Scientists have also published studies resulting in major changes to the classification above the species level, for example by studying snout moth “ears” (tympanal organs) and utilizing genes to study their relationships.

This check list was compiled over a three-year period by Dr. Brian Scholtens and Dr. M. Alma Solis. Brian Scholtens is a professor at the College of Charleston, South Carolina, and M. Alma Solis is a research entomologist at the Agriculture Research Service’s Systematic Entomology Laboratory, and curator of the U.S. National Pyraloidea Collection located at the Smithsonian Institution, National Museum of Natural History, Washington, D.C. Their results have been published in the open-access journal ZooKeys.

“A check list is one of the most important pieces of research, with many applications,” says Dr. Solis. “Knowing the fauna of a geographic area makes it possible to track species and, in this case, potential invasive species. The caterpillars of snout moths are economically important worldwide as pests of planted crops for food or biofuel, of forest trees, and of stored products such as wheat and nuts.”

“Many species, for example, the stored product pests, occur worldwide, but others, such as pest species of grasses including corn, can be restricted or only exist in certain geographic areas,” the scientist further explains. “It is important to be able to recognize as soon as possible that a particular species is not native to the United States or Canada.”

Scientists use Latin scientific names as “unique tags” to communicate about the morphological or molecular identity and habits of a species. One of the functions of taxonomists is to determine if a species is new or if it has already been described. Historically, confusion is created when the same species is described more than once (called a synonym) in other parts of the world.

A regional check list such as this one and a worldwide check list can work together to reinforce precision in the definition and communication about species, especially decreasing confusion about synonyms. Most worldwide check lists exist as online databases that can be updated. Dr. Solis said that they had cited new discoveries relevant to the North American snout moth fauna found in GLOBIZ, or the Global Information System on Pyraloidea, an electronic list of over 15,500 snout moth species names for which she is a collaborator.

Serendipitous orchid: An unexpected species discovered in Mexican deciduous forests

A new elegant orchid species that grows on rocks in deciduous forests of the Pacific slope of Oaxaca state, Mexico, has finally put an end to a long standing dispute among taxonomists. ‘Sheltered’ under the name of a close relative, the plant has been proved by a research team, led by Dr. Leopardi-Verde, to be different enough for a species of its own. Its distinct features, including shape, size and colors, are discussed and published in the open-access journal PhytoKeys.

When scientists Drs. Carlos L. Leopardi-Verde, Universidad de Colima and Centro de Investigacion Cientifica de Yucatan, German Carnevali and Gustavo A. Romero-Gonzalez, both affiliated with Centro de Investigacion Cientifica de Yucatan and Harvard University Herbaria, stumbled across a beautiful orchid in bloom, they found themselves so surprised by its unique colors and forms that later on they chose the specific epithet inopinatus, meaning “unexpected”.

One of the most distinctive characters of the new plant is the yellow labellum patterned with crimson to reddish brown lines. Typically for its species complex, this orchid’s leaves are wide and leatherlike and the flowers are relatively large, showy, and leathery to fleshy-leathery petals and sepals. The color of the flowers varies from bronze-green with dark purple lines near the base to pale pink and creamy white splashed with reddish-brown spots and lines towards the top.

The plant is between 30 and 42 cm tall, while together with its flowers it reaches between 80 and 90 cm. Each branch of the inflorescence bears from 3 to 8 flowers, which bloom between March and July. Having been recorded only from a few sites on the Pacific slope of Oaxaca state, Mexico, the species appears to be rare.

The authors explain the similarities between the new species and its close relatives. They also discuss the long-held confusion about its taxonomic placement. As a result of the study, a hypothesis about hybridization that has played a role in the evolution and origin of the novelty has been refuted.

From Sherborn to ZooBank: Moving to the interconnected digital nomenclature of the future

From the outside, it can seem that taxonomy has a commitment issue with scientific names. They shift for reasons that seem obscure and unnecessarily wonkish to people who simply want to use names to refer to a consistent, knowable taxon such as species, genus or family. However, the relationship between nomenclature and taxonomy, as two quite separate but mutually dependent systems, is a sophisticated way of balancing what we know and what is open to further interpretation.

Nomenclature is a bureaucracy that follows rules and is tied to published records and type specimens. It provides a rigid framework or skeleton for knowledge. Taxonomy, on the other hand, is a data-driven science, influenced by interpretation and resulting in concepts that are open to further test and change. To actually get the answers right, taxonomy needs to be responsive and fluid as a system of knowledge. The link between nomenclature and the published record is also the junction with the data that fuels taxonomic interpretation.

Biodiversity informatics aims to solve this issue, and its founding father is Charles Davies Sherborn. His magnum opus, Index Animalium, provided the bibliographic foundation for current zoological nomenclature. In the 43 years he spent working on this extraordinary resource, he anchored our understanding of animal diversity through the published scientific record. No work has equaled it, and it is still in current and critical use.

ZK 550 SI Cover_LAST-1This special volume of the open-access journal ZooKeys celebrates Sherborn, his contributions, context and the future for the discipline of biodiversity informatics. The papers in this volume fall into three general areas of history, current practice and frontiers.

The first section presents facets of Sherborn as a man, scientist and bibliographer, and describes the historical context for taxonomic indexing from the 19th century to today. The second section discusses existing tools and innovations for bringing legacy biodiversity information into the modern age. The final section tackles the future of biological nomenclature, including digital access, innovative publishing models and the changing tools and sociology needed for communicating taxonomy.

In the late 1880s Charles Davies Sherborn recognised the need for a full index of names to the original sources that gave them legitimacy, their first publications. He set about making a complete index for names of animals, which are the largest group of described organisms (1.4 million of the current 1.8 million described species are animals). Because this work began while the very basics of nomenclatural rules were being thrashed out, the work itself affected how those rules were codified.

Sherborn’s monumental work, Index Animalium, comprises more than 9,000 pages in 11 volumes and about 440,000 names. This was on the scale of other hugely ambitious tasks at the time that changed the course of communication such as the Oxford English Dictionary. The error rates are astonishingly low, and it became, and it remains to date the most complete reference source for animal nomenclature. Taxonomic studies rely on Sherborn’s work today. While the future for information access is one of the most exciting frontiers for our increasingly interconnected, accelerated society, biodiversity information will continue to be grounded in this seminal work. The future for biodiversity informatics is built on Sherborn’s work, and is expanding to be digital, diversified and accessible.

The publisher of this volume, the journal ZooKeys, is itself a pioneer in developing a more stable and accessible scientific nomenclature. Together with PhytoKeys, ZooKeys is piloting an innovative workflow with a pre-publication automated pipeline for registration of nomenclatural acts. This initiative comes from the EU FP7 project pro-iBiosphere, and in close collaboration with ZooBank (the official online registry for scientific names of animals), Zoological Record, IPNI, MycoBank and Index Fungorum, and the Global Names project. The volume was inspired by a symposium held in Sherborn’s honour at the Natural History Museum (NHM), London, on the 150th year of his birth in 2011, organised by the International Commission on Zoological Nomenclature (ICZN), in collaboration with the Society for the History of Natural History (SHNH).

Sherborn was a man with a vision for the future and respect for the accomplishments of the past. He would have celebrated the new tools for the ambitious goal of linking all biological information through names that are readable for both machines and humans. He would have understood the tremendous power of interconnected names for biodiversity science overall. And he would have knuckled down and got to work to make it happen.

A botanical survey to help understand change in our wild flora

Volunteers in the north-east of England have created a benchmark survey of common plants with which to identify change in the countryside, its result and causes. This survey will be used in future to monitor the effects of climate change on plants; assess the success of conservation measures and predict future change. Its findings are published in the open-access journal Biodiversity Data Journal, contributing an additional 35,000 observations to the 200,000 observations collected by local recorders since the turn of the millennium .

Many people remark on the changes that are occurring in the countryside, the disappearance of some species and the spread of others. Yet, these anecdotes cannot substitute for hard facts. There are also many suggested causes for all these changes such as warmer climate, different agricultural practices, eutrophication, or alien species. Botanical observations tend to be biased. For example, common species are often ignored in the interest of exceptional ones. Therefore, what was needed was a dedicated survey with a clear and repeatable methodology.

Common plant species are the mainstay of habitats, they create our woodlands, hedgerows and meadows. They also provide the food for herbivores and pollinators and create homes for birds and mammals. Changes in the abundance of rare species have little impact on other species, but change in the abundance of common species can have cascading effects on whole ecosystems of which we are a part.

For these reasons volunteer botanists in the north-east of England conducted a four-year survey to benchmark the abundance of common plants. Led by the Botanical Societies vice county recorders, John Durkin Ecology, Botanical Society of Britain and Ireland, and Botanic Garden Meise, the volunteers surveyed the plants in a randomly selected sample of 1km2 grid squares in the vice counties of Durham and South Northumberland.

They created a solid foundation that can be used to qualify the abundance of common species and compare against previous and future studies. The project was conducted over four years and required volunteers to go to various places. Some surveyed post-industrial brown-field sites, while others walked for miles across bleak moorland to reach sites high in the hills. Although these moors are arguably wilder and natural, the industrial wastelands turn out to be far more biodiverse.

Botanical surveying continues in the region despite the end of the project. Volunteers continue to monitor rare plants in the region and are currently working towards the next atlas of Britain and Ireland, coordinated by the Botanical Society of Britain and Ireland.

“Good biological conservation in the 21st century will have as much to do with sensitive adaption to change as it is about preserving what we have,” point out the authors. “Human memory is short and fickle and it is only with benchmark surveys, such as this that we can hope to understand and manage that change.”
