Total of 21 new parasitoid wasps following the first ever revision of their genus

As many as twenty-one species of parasitoid wasps are described as new to science, following the first ever revision of their genus since its establishment back in 1893.

The study simultaneously updates the count of species within the genus (Chromoteleia) to 27 in total, produces a systematic revision of the world’s representatives of this group of wasps, expands their biogeographic knowledge, and clarifies their generic concept.

The monograph is published in the open access journal ZooKeys by a team of US and Canadian scientists, led by Hua-yan Chen, graduate student at the Ohio State University.

The wasps in the genus Chromoteleia are easily distinguished thanks to their large size in combination with their vivid colouration. Compared to other species in the family of platygastrid wasps, which normally measure merely 1 – 2 mm in length, the species in the studied genus range between 3 and 9 mm. Their uncommonly large, robust and elongated bodies is why the scientists assume that these wasps likely parasitise the eggs of orthopterans, such as grasshoppers, crickets and katydids.

A focal point in the study is the intriguing distribution of the wasps. While the genus is widespread throughout continental Mesoamerica, Central America and South America, and its distribution ranges from the Mexican state of Jalisco in the north all the way to Itapúa Department in Paraguay and Paraná in southern Brazil, the species C. congoana is a lone representative of the genus in Africa.

The ‘lone’ African representative of the genus, Chromoteleia congoana.

While dispersal from South America to Africa has been observed in the past in another genus of parasitoid wasps (Kapala), the scientists are not willing to reject the possibility of Chromoteleia wasps having been widely distributed across the Old World during a previous geological epoch. Such phenomenon, also known as a relict population, would not mean that the wasp group has subsequently ‘conquered’ the Neotropics and current species inhabiting the New World are rather remainders of once widespread insects.

To conclude their findings, the scientists examined specimens hosted in collections at twenty natural history institutions from around the globe, including the American Entomological Institute; American Museum of Natural History; Bernice P. Bishop Museum; California Academy of Sciences; Canadian National Collection of Insects; California State Collection of Arthropods; Florida State Collection of Arthropods; Instituto Alexander von Humboldt; Illinois Natural History Survey; Kansas University’s Natural History Museum; Museo del Instituto de Museo del Instituto de Zoologia Agricola; Museum National d’Histoire Naturelle; Museu Paraense Emílio Goeldi; Lund Museum of Zoology at Lund University; Triplehorn Insect Collection at the Ohio State University; South African Museum; Texas A&M University’s Insect Collection; Bohart Museum of Entomology; University of Colorado; and Smithsonian National Museum of Natural History.

Right under our noses: A novel lichen-patterned spider found on oaks in central Spain

It happened again, a previously unknown spider species, whose home is a strongly humanised European country, appears to have been quietly and patiently waiting to get noticed until very recently.

Living on the trunks of oaks in Spain, the new species would have probably been spotted decades ago, had it not been for its sophisticated camouflage, which allows the small arachnid to perfectly blend with the lichens naturally growing on the tree.

Going by the name Araneus bonali, the new species was discovered on isolated trees at the borders of cereal fields by the scientists Eduardo Morano, University of Castilla-La Mancha, and Dr Raul Bonal, University of Extremadura. Their study is published in the open access journal ZooKeys.

Curiously enough, this is the same habitat, where the team found another new spider in 2016.

“How many new species remain unknown in these isolated oaks that once formed vast forests now becomes one even more intriguing question,” say the researchers.

“Anyone going for a walk around any village or park in central Spain would have been close to the new species. However, noticing it requires not only curiosity, but also a good sight, as its lichen-like colours make up an excellent mimicry.”

The similarity between the adults and the lichens that cover the oak trunks they inhabit is remarkable. Meanwhile, the greenish juveniles live amongst the green new shoots in the oak canopy until they reach maturity.

Whether the spider uses its mimicry to avoid predators or rather surprise its prey remains open for further investigation.

The description of this new species that belongs to the popular group of orb-weavers once again stresses the need of working harder on completing the list of spiders living in the Old World, such as the countries in the Mediterranean basin – a region that certainly keeps more taxonomic surprises up his sleeve.

Mosquito populations give a new insight into the role of Caucasus in evolution

We know that the Caucasus is a relatively large mountainous region, situated between Black and the Caspian seas. In its turn, it is divided into three subregions: Ciscaucasia, Greater Caucasus and Transcaucasia, also known as South Caucasus.

A closer look into the chromosome structure of mosquito larvae of a curious group of species (Chironomus “annularius” sensu Strenzke (1959)), collected from the three localities, has allowed Dr Mukhamed Karmokov of the Tembotov Institute of Ecology of Mountain territories at the Russian Academy of Science to figure out how the specificity of the Caucasian region has simultaneously unified its fauna geographically, yet has divided it evolutionarily. His paper is published in the open access journal Comparative Cytogenetics.

Having collected a sufficient amount of mosquito larvae, the researcher managed to study the chromosome structure, rearrangements and possible peculiarities of the separate Caucasian populations, in order to compare them.

Additionally, he analysed their relations to earlier known populations from Europe, Siberia, Kazakhstan and North America.

Amongst the curious peculiarities Karmokov identified in the chromosome structure of the studied larvae were some rearrangements which appear unique to Caucasus. Furthermore, he found that despite the close geographic proximity, the genetic distance between the Caucasian populations is quite significant, even While not enough to determine them as separate species, it could prove them as separate subspecies.

In conclusion, the scientist notes that the obtained data confirm that the Caucasian populations of the studied species have complex genetic structure and provide evidence for microevolution processes in the region.

How many sharks, chimaeras, skates, and rays inhabit Mexico?

Worldwide, Mexico is well-known for a lot of things: its cuisine, tequila, mariachis, pyramids, and beaches, as well as being the country with the most Spanish-speaking residents (more than 120 million people).

In contrast, however, little is known for the country’s chondrichthyan fauna: a class of fishes containing the sharks, chimaeras, rays, and skates.

To fill the gap in the knowledge of the Mexican marine fauna, scientists from the Instituto Politécnico Nacional – Centro Interdisciplinario de Ciencias Marinas  (IPN-CICIMAR) conducted a multidisciplinary study on the extant species of the country’s Economic Exclusive Zone (EEZ) and, as a result, reported a total of 217 extant chondrichthyan species. Their findings are published in the open access journal ZooKeys.

In their updated taxonomic list, the team of Dr. José De La Cruz-Agüero, Dr. Jorge Guillermo Chollet-Villalpando, and Venezuelan graduate students Lorem González-González and Nicolás R. Ehemann report eight chimaeras, 111 sharks and 98 ray and skate species. These numbers equate to 18% of the world’s chondrichthyans.

Split between the Mexican coasts there are 92 species recorded from the Mexican Pacific and the Gulf of California, whereas 94 fishes are identified for the Gulf of Mexico and the Caribbean Sea. Additionally, 31 species are known from both coasts.

“The species richness will undoubtedly continue to increase, due to the current investigations in progress, as well as the exploration of deep-water fishing areas in the EEZ,” comment the scientists.

Considered to be primitive fishes, sharks, skates, chimaeras, and rays are believed to have been inhabiting the planet for the last 420-450 million years. To put it in perspective, the earliest evidence of our species – Homo sapiens – is pretty ‘young’ at 315,000 years.

Not only do these species are peculiar with their lack of a bony skeleton when compared to the more recently evolved fishes, but they also have an unusual digestive system, featuring a spiral valve, where the lower intestine is twisted like a corkscrew to increase the surface area. They don’t have a swimming bladder either. Further, there are about 650 extant species, whereas the known bony fishes are estimated to be over 35,000.  

Most of the chondrichthyans are considered either ‘Critically Endangered’ (a classification a step below ‘Extinct’) or ‘Endangered’, according to the Red List of the International Union for Conservation of Nature (IUCN). The majority are also featured in the Convention on International Trade in Endangered Species.

As if to make matters worse, these fishes are also particularly susceptible to overfishing and have a low rate of growth and fecundity (females give birth to between 1 and 25 pups a year).

Described 28 years post-collection, new grass species makes a strong case for conservation

Originally collected 28 years ago in Ecuador, new species Poa laegaardiana has been just described, only to find out its prospects for surviving in its type location seem bleak nowadays. The study was published in the open access journal PhytoKeys.

When roaming in the Cordillera de los Andes of Ecuador, near the village of Facundo Vela, little did Smithsonian scientist and author, Dr. Paul M. Peterson, know that a small grass specimen will not only turn out to be an intriguing new species, but will also make a big statement on the importance of conservation.

Scientific drawing showing what makes new species P. laegaardiana distinct from its congeners

Almost three decades after its original collection the new species P. laegaardiana has finally emerged from its herbarium collection, but the story took an unexpected twist.

It took the authors a single Google Earth search to find out that what used to be the natural habitat of the newly found densely tufted bunchgrass, is now occupied predominantly by small farms.

Heavy agricultural use of the terrain, poses a good possibility for P. laegaardiana to have already been extirpated from this location. With the species currently known only from this area, chances are that this newly described species, might in fact turn out to be already extinct.

“Further studies are needed to search the area and browse collections for specimens from different locations,” explains Dr. Peterson. “But, in fact, it may well be that with our study we are documenting a possible extinction of a species, happening in the space of just 30 years. The story of P. laegaardiana serves to show how human-induced habitat loss can indeed be a major threat to the survival of life on Earth.”

The new species was named after renowned Danish botanist Simon Laegaard, who has made extensive collections in South America, Greenland, Ecuador, and Bolivia (accompanied by the authors) contributing to the documentation of the flora to make informed conservation and management plans.

Out of the darkness: A new spider found deep within an Indiana cave

Lead author Marc Milne in the Stygian River Cave and a male specimen of the newly described Islandiana lewisi 

Spiders are ubiquitous within our forests, fields, and backyards. Although you may be used to seeing the beautiful yellow and black spiders of the genus Argiope in your garden, large ground-scurrying wolf spiders in your yard, or spindly cellar spiders in your basement, this new sheet-web-building spider is probably one you haven’t seen before. The reason is that it’s known from a single cave in the world, Stygeon River Cave, in southern Indiana.

The University of Indianapolis assistant professor, Dr. Marc Milne, described the rare species in the open access journal Subterranean Biology with the help of a University of Indianapolis alumnus, Elizabeth Wells, who illustrated the spider for the manuscript.

Sheet weavers, also known as dwarf spiders or money spiders, are minute creatures growing no larger than a few centimetres in length, which makes them particularly elusive. Their peculiar webs are flat and sheet-like, hence their common English name.

Female of the new species Islandiana lewisi

The new spider, Islandiana lewisi, is an homage. Milne was shown the spider by a fellow scientist, Dr. Julian Lewis, who noticed the critter on one of his many cave expeditions. In appreciation for his help, Milne and Wells named the spider after Lewis.

This is the fifteenth species in its genus (Islandiana) and the fifth known to live exclusively in caves. It has been over 30 years since the last species has been added to this group.

At about 2 mm in size, Islandiana lewisi is thought to feed on even smaller arthropods, such as springtails living in the debris on the cave floor. It is unknown when it reproduces or if it exists anywhere else. The spider is likely harmless to humans.

The collectors of the spider, Milne and Lewis, described the hostile conditions within the cave, which the new species calls home: “because the cave floods from time to time, the insides were wet, muddy, slippery, and dangerous to walk on without the proper equipment.”

Milne and Lewis found the spider in small, horizontal webs between large, mud-caked boulders in the largest room in the cave. It was collected in October 2016 with the permission of the landowner.

Milne hypothesized that he had collected something special, stating, “I didn’t know what the spider was at first, I just thought it was odd that so many were living within this dark cave with no other spider species around.”

After returning to the lab and inspecting the spider under a microscope, Milne initially misidentified the species. However, when he re-examined it months later, he realized that the species was indeed new to science.

First-ever fern checklist for Togo to help decision makers in the face of threats to biodiversity

Maidenhair fern (Adiantum schweinfurthii) occurring in dense forests.

Ferns and their allied species, which together comprise the pteridophytes, are vascular non-flowering plants that reproduce via spores. Many of their species are admired for their aesthetics.

However, despite being excellent bioindicators that allow for scientists and decision-makers to monitor the state of ecosystems in the face of climate change and global biodiversity crisis, these species are too often overlooked due to their relatively small size and lack of vivid colours.

To bridge the existing gaps in the knowledge about the diversity of ferns and their allied species, while also seeking to identify the ways these plants select their habitats and react to the changes occurring there later on, a research team from Togo and France launched an ambitious biodiversity project in 2013. As for the setting of their long-term study, they chose Togo – an amazingly species-rich country in Western Africa, whose flora expectedly turned out to be hugely understudied.

Having concluded their fern project in 2017, scientists Komla Elikplim Abotsi and Kouami Kokou from the Laboratory of Forestry Research, University of Lomé, Togo, who teamed up with Jean-Yves Dubuisson and Germinal Rouhan, both affiliated with the Institute of Systematics Evolution and Biodiversity (UMR 7205), France, have their first findings published in a taxonomic paper in the open access Biodiversity Data Journal.

In this first-of-a-kind checklist of Togolese ferns, the researchers record as many as 73 species previously not known to inhabit the country, including 12 species introduced for horticultural purposes. As a result of their 4-year study, the pteridophyte diversity of Togo – a country barely taking up 56,600 km² – now counts a total of 134 species.

Still, the authors believe that there are even more species waiting to be discovered on both national and global level.

“Additional investigations in the difficult to access areas of the far north of the country, and Togo Mountains are still needed to fill possible biodiversity data gaps and enable decision-makers to make the right decisions,” say the researchers.

In addition to their taxonomic paper, the authors are also set to publish an illustrated guide to the pteridophytes of Togo, in order to familiarise amateur botanists with this fascinating biodiversity.

Six new species of goblin spiders named after famous goblins and brownies

 

Fictional characters originally ‘described’ by famous English children’s writer Enid Blyton have given their names to six new species of minute goblin spiders discovered in the diminishing forests of Sri Lanka.

The goblins Bom, Snooky and Tumpy and the brownies Chippy, Snippy and Tiggy made their way from the pages of: “The Goblins Looking-Glass” (1947), “Billy’s Little Boats” (1971) and “The Firework Goblins” (1971) to the scientific literature in a quest to shed light on the remarkable biodiversity of the island country of Sri Lanka, Indian Ocean.

As a result of their own adventure, which included sifting through the leaf litter of the local forests, scientists Prof. Suresh P. Benjamin and Ms. Sasanka Ranasinghe of the National Institute of Fundamental Studies, Sri Lanka, described a total of nine goblin spider species in six genera as new to science. Two of these genera are reported for the very first time from outside Australia.

Their paper is published in the open access journal Evolutionary Systematics.

With a total of 45 species in 13 genera, the goblin spider fauna in Sri Lanka – a country taking up merely 65,610 km2 – is already remarkably abundant. Moreover, apart from their diversity, these spiders amaze with their extreme endemism. While some of the six-eyed goblins can only be found at a few sites, other species can be seen nowhere outside a single forest patch.

“Being short-range endemics with very restricted distributions, these species may prove to be very important when it comes to monitoring the effects of climate change and other threats for the forest habitats in Sri Lanka,” explain the researchers.

In European folklore, goblins and brownies are known as closely related small and often mischievous fairy-like creatures, which live in human homes and even do chores while the family is asleep, since they avoid being seen. In exchange, they expect from their ‘hosts’ to leave food for them.

Similarly, at size of a few millimetres, goblin spiders are extremely tough to notice on the forest floors they call home. Further, taking into consideration the anthropogenic factors affecting their habitat, the arachnids also turn out to be heavily dependent on humans.

Museum collection reveals distribution of Carolina parakeet 100 years after its extinction

While 2018 marks the centenary of the death of the last captive Carolina parakeet – North America’s only native parrot, a team of researchers have shed new light on the previously known geographical range of the species, which was officially declared extinct in 1920.

Combining observations and specimen data, the new Carolina parakeet occurrence dataset, recently published in the open access Biodiversity Data Journal by Dr Kevin Burgio, , Dr Colin Carlson, University of Maryland and Georgetown University, and Dr Alexander Bond, Natural History Museum of London, is the most comprehensive ever produced.

The new study provides unprecedented information on the birds range providing a window into the past ecology of a lost species.

“Making these data freely available to other researchers will hopefully help unlock the mysteries surrounding the extinction and ecology of this iconic species. Parrots are the most at-risk group of birds and anything we can learn about past extinctions may be useful going forward,” says the study’s lead author, Kevin Burgio.

The observational recordings included in the study have been gleaned from a wide variety of sources, including the correspondence of well-known historical figures such as Thomas Jefferson and the explorers Lewis and Clark.

The study team referenced recorded sightings spanning nearly 400 years. The oldest recorded sighting dates back to 1564, and was found in a description of the current state of Florida written by Rene Laudonniere in 1602.

Alongside the written accounts, the researchers included location data from museum specimens. These include 25 bird skins from the Natural History Museum’s Tring site, whose skin collection is the second largest of its kind in the world, with almost 750,000 specimens representing about 95 per cent of the world’s bird species. Thereby, the study proves what invaluable resources museum collections can be.

“The unique combination of historical research and museum specimens is the only way we can learn about the range of this now-extinct species. Museums are archives of the natural world and research collections like that of the Natural History Museum are incredibly important in helping to increase our understanding of biodiversity conservation and extinction,” says Alex Bond.

“By digitising museum collections, we can unlock the potential of millions of specimens, helping us to answer some of today’s big questions in biodiversity science and conservation.”

It is hoped that this research will be the beginning of a wider reaching work that will explore further into the ecology of this long lost species.

Naming rights for 5 new snail-sucking snake species auctioned to save rainforests in Ecuador

The existence of five delightfully weird snail-sucking snakes slithering through the forest floors of Ecuador was announced by a group of scientists in a study in the open access journal Zookeys.

Believe or not, there is an entire group of snakes for which snails are number one on their menu. This is why their jaws are modified in such a way that they can suck the viscous slimy body of a snail right out of its shell.

Luckily for us, these snakes are harmless to humans. However, humans are not harmless to them. Four out of the five newly discovered species are already facing the possibility of becoming extinct, as the forest remnants they call home are currently being destroyed.

In a bid to take care after the unfortunate reptiles, the scientists auctioned the naming rights for the new species at a recent event in New York City. The money are to purchase and save a previously unprotected 72 ha (178 acre) plot of land where some of these species live.

To do so, Fundación Jocotoco is to add the purchased plot to the Buenaventura reserve, in order to expand the only protected area where two of the new snakes are found, and prevent these endangered snake species from going extinct.

Three of the five species were discovered during a series of expeditions to three rainforests in Ecuador between 2013 and 2017, conducted by Alejandro Arteaga, an Ecuadorian–Venezuelan PhD student at the American Museum of Natural History and scientific director of Tropical Herping, who partnered with Dr. Alex Pyron, The George Washington University and National Museum of Natural History, USA.

In another habitat type, the dry forest, Ecuadorian scientists Dr. Omar Torres-Carvajal, Pontificia Universidad Católica del Ecuador (PUCE), David Salazar-Valenzuela, Universidad Tecnológica Indoamérica, Diego Cisneros-Heredia, Universidad San Francisco de Quito, Juan Carlos Sánchez, Universidad del Azuay, Mario Yánez-Muñoz, Instituto Nacional de Biodiversidad  (INABIO), and Peruvian scientist Pablo Venegas, CORBIDI, noted the existence of the other two new species.

“We had to let people know that these cool snakes exist,” Alejandro said, “and that these species might soon stop to exist, and we need people’s help to protect the snake’s habitat.”

In order to confirm these five snakes as new species, the team of researchers, particularly Drs. Konrad Mebert, Universidade Estadual de Santa Cruz, Nicolás Peñafiel, Universidad Tecnológica Indoamérica, Gabriela Aguiar, Tropical Herping, and Timothy Colston, The George Washington University and National Museum of Natural History, USA, counted scales and gathered measurements from more than 200 museum specimens, and extracted DNA from nearly 100 snakes.

PhD student Alejandro Arteaga measured snake specimens at various museums, including the American Museum of Natural History in New York City.

Having made the highest bid at the auction, Rainforest Trust (RT) and Bob Ridgely got to name three of the five new snakes.

Thus, the species Dipsas georgejetti now honors George Jett, who supported the inception of Fundación Jocotoco’s reserves in Ecuador; while Dipsas bobridgelyi is a tribute to Dr. Robert “Bob” S. Ridgely, a leading ornithologist and distinguished conservationist who helped the establishment of the Buenaventura reserve. Bob, who was at the auction, chose the name Sibon bevridgelyi (Bev Ridgely’s Snail-Eater) to honor his father.

The remaining two snail-eating species, Dipsas oswaldobaezi and D. klebbai, were named after Dr. Oswaldo Báez and Casey Klebba, respectively, in recognition for their passion for Ecuador’s biodiversity and conservation.

“Several companies let you name a star after a loved one,” Alejandro says, “but, generally, such names have no formal validity. Naming an entire species after someone you love or admire is different. With few exceptions, this is the name that both the general public and the whole scientific community will use. So, why not let people choose the name of a species in exchange for a donation that protects its habitat?”

The act of naming species is essential in raising awareness about the existence of a species and its risk of extinction, but it also provides an opportunity to recognize and honor the work of the people and institutions fighting to protect the species.

“Naming species is at the core of biology,” says Dr. Juan M. Guayasamin, co-author of the study and a professor at Universidad San Francisco in Quito. “Not a single study is really complete if it is not attached to the name of the species, and most species that share the planet with us are not described.”

“Everybody knows elephants and orangutans,” says Dr. Martin Schaefer of Fundación Jocotoco, “but some reptiles and amphibians are even more threatened. Yet, we still lack even the basic information to protect them better. This is why the work by scientists is so important; it provides the necessary information to guide our conservation decisions.”

“Through photography or by joining a scientific expedition, the general public can learn more about hidden biodiversity and how threatened it is,” says Lucas Bustamante of Tropical Herping. “This is a model to obtain support for research and conservation while recruiting more environmental ambassadors.”
