The new species are amongst the very first bald-legged spiders recorded in Colombia

Despite being widely distributed across north and central South America, bald-legged spiders had never been confirmed in Colombia until the recent study by the team of Drs Carlos Perafan and Fernando Perez-Miles (Universidad de la Republica, Uruguay) and William Galvis (Universidad Nacional de Colombia). Published in the open-access journal ZooKeys, their research paper describes a total of six previously unknown species inhabiting the country.

Four of the novel spiders were unable to fit into any already existing genus, so the scientists had to create a brand new one for them, which they called Stormtropis in reference to the Star Wars‘ clone trooper army known as Stormtroopers.

Considered to be amongst the most enigmatic in the group of mygalomorphs, the bald-legged spiders are a family of only 11 very similarly looking, small- to medium-sized species, whose placement in the Tree of Life has long been a matter of debate. In fact, it is due to their almost identical appearance and ability for camouflage that became the reason for the new bald-legged spider genus to be compared to the fictional clone troopers.

One of the most striking qualities of the bald-legged spiders (family Paratropididae) is their ability to adhere soil particles to their cuticle, which allows them to be camouflaged by the environment.

“The stormtroopers are the soldiers of the main ground force of the Galactic Empire. These soldiers are very similar to each other, with some capacity for camouflage, but with unskillful movements, like this new group of spiders,” explain the researchers.

“We wanted to make a play on words with the name of the known genus, Paratropis, and of course, we also wanted to pay tribute to one of the greatest sagas of all time”, they add.

One of the new ‘stormtrooper’ species (Stormtropis muisca) is also the highest altitudinal record for the family. It was recorded from an elevation of at least 3,400 m in the central Andes. However, the authors note that they have evidence of species living above 4,000 m. These results are to be published in future papers.

In the course of their fieldwork, the researchers also confirmed previous assumptions that the bald-legged spiders are well adapted to running across the ground’s surface. The spiders were seen to stick soil particles to their scaly backs as a means of camouflage against predators. More interestingly, however, the team records several cases of various bald-legged species burrowing into ravine walls or soil – a type of behaviour that had not been reported until then. Their suggestion is that it might be a secondary adaptation, so that the spiders could exploit additional habitats.

In conclusion, not only did the bald-legged spiders turn out to be present in Colombia, but they also seem to be pretty abundant there. Following the present study, three genera are currently known from the country (Anisaspis, Paratropis and Stormtropis).

New tarantula species from Angola distinct with a one-of-a-kind ‘horn’ on its back

A new to science species of tarantula with a peculiar horn-like protuberance sticking out of its back was recently identified from Angola, a largely underexplored country located at the intersection of several Afrotropical ecoregions.

Collected as part of the National Geographic Okavango Wilderness Project, which aims to uncover the undersampled biodiversity in the entire Okavango catchment of Angola, Namibia and Botswana, thereby paving the way for sustainable conservation in the area, the new arachnid is described in a paper published in the open-access journal African Invertebrates by the team of Drs John Midgley and Ian Engelbrecht.

Although the new spider (Ceratogyrus attonitifer sp.n.) belongs to a group known as horned baboon spiders, the peculiar protuberance is not present in all of these species. Moreover, in the other species – where it is – the structure is completely sclerotised, whereas the Angolan specimens demonstrate a soft and characteristically longer ‘horn’. The function of the curious structure remains unknown.

The new tarantula’s extraordinary morphology has also prompted its species name: C. attonitifer, which is derived from the Latin root attonit– (“astonishment” or “fascination”), and the suffix –fer (“bearer of” or “carrier”). It refers to the astonishment of the authors upon the discovery of the remarkable species.

“No other spider in the world possesses a similar foveal protuberance,” comment the authors of the paper.

During a series of surveys between 2015 and 2016, the researchers collected several female specimens from the miombo forests of central Angola. To find them, the team would normally spend the day locating burrows, often hidden among grass tufts, but sometimes found in open sand, and excavate specimens during the night. Interestingly, whenever the researchers placed an object in the burrow, the spiders were quick and eager to attack it.

The indigenous people in the region provided additional information about the biology and lifestyle of the baboon spider. While undescribed and unknown to the experts until very recently, the arachnid has long been going by the name “chandachuly” among the local tribes. Thanks to their reports, information about the animal’s behaviour could also be noted. The tarantula tends to prey on insects and the females can be seen enlarging already existing burrows rather than digging their own. Also, the venom of the newly described species is said to not be dangerous to humans, even though there have been some fatalities caused by infected bites gone untreated due to poor medical access.

In conclusion, the researchers note that the discovery of the novel baboon spider from Angola does not only extend substantially the known distributional range of the genus, but can also serve as further evidence of the hugely unreported endemic fauna of the country:

“The general paucity of biodiversity data for Angola is clearly illustrated by this example with theraphosid spiders, highlighting the importance of collecting specimens in biodiversity frontiers.”

Apart from the described species, the survey produced specimens of two other potentially new to science species and range expansions for other genera. However, the available material is so far insufficient to formally diagnose and describe them.

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.

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.

Dispatch from the field II: Students describe an elusive spider while stationed in Borneo

A mystery has long shrouded the orb-weaving spider genus Opadometa, where males and females belonging to one and the same species look nothing alike. Furthermore, the males appear to be so elusive that scientists still doubt whether both sexes are correctly linked to each other even in the best-known species.

Such is the case for Opadometa sarawakensis – a species known only from female specimens. While remarkable with their striking red and blue colors and large size, the females could not give the slightest hint about the likely appearance of the male Opadometa sarawakensis.

The red and blue female Opadometa sarawakensis — The red and blue female *Opadometa sarawakensis*

Nevertheless, students taking part in a recent two-week tropical ecology field course organized by the Naturalis Biodiversity Center and Leiden University, and hosted by the Danau Girang Field Centre (DGFC) on the island of Borneo, Malaysia, found a mature male spider hanging on the web of a red and blue female, later identified as Opadometa sarawakensis. Still quite striking, the male was colored in a blend of orange, gray, black, and silver.

At the brink of a long-awaited discovery and eager to describe the male, the students along with their lecturers and the field station scientific staff encountered a peril – with problematic species like the studied orb weaver they were in need for strong evidence to prove that it matched the female from the web. Furthermore, molecular DNA-based analysis was not an option at the time, since the necessary equipment was not available at DGFC.

On the other hand, being at the center of the action turned out to have advantages no less persuasive than DNA evidence. Having conducted thorough field surveys in the area, the team has concluded that the male’s observation on that particular female’s web in addition to the fact that no other Opadometa species were found in the area, was enough to prove they were indeed representatives of the same spider.

Adapting to the quite basic conditions at the DGFC laboratory, the students and their mentors put in use various items they had on hand, including smartphones paired up with headlights mounted on gooseneck clips in place of sophisticated cameras.

In the end, they gathered all the necessary data to prepare the formal description of the newly identified male.

Once they had the observations and the data, there was only one question left to answer. How could they proceed with the submission of a manuscript to a scholarly journal, so that their finding is formally announced and recognised?

Thanks to the elaborated and highly automated workflow available at the peer-reviewed open access Biodiversity Data Journal and its underlying ARPHA Writing Tool, the researchers managed to successfully compile their manuscript, including all underlying data, such as geolocations, and submit it from the field station. All in all, the authoring, peer review and publication – each step taking place within the ARPHA Platform‘s singular environment – took less than a month to complete. In fact, the paper was published within few days after being submitted.

This is the second publication in the series “Dispatch from the field”, resulting from an initiative led by spider taxonomist Dr Jeremy Miller. In 2014, another team of students and their mentors described a new species of curious one-millimetre-long spider from the Danau Girang Field Center. Both papers serve to showcase the feasibility of publication and sharing of easy to find, access and re-use biodiversity data.

“This has been a unique educational experience for the students,” says Jeremy. “They got to experience how tropical field biologists work, which is often from remote locations and without sophisticated equipment. This means that creativity and persistence are necessary to solve problems and complete a research objective. The fact that the students got to participate in advancing knowledge about this remarkable spider species by contributing to a manuscript was really exciting.”

Spider eat spider: Scientists discover 18 new spider-hunting pelican spiders in Madagascar

In 1854, a curious-looking spider was found preserved in 50 million-year-old amber. With an elongated neck-like structure and long mouthparts that protruded from the “head” like an angled beak, the arachnid bore a striking resemblance to a tiny pelican. A few decades later when living pelican spiders were discovered in Madagascar, arachnologists learned that their behavior is as unusual as their appearance, but because these spiders live in remote parts of the world they remained largely unstudied–until recently.

At the Smithsonian’s National Museum of Natural History, curator of arachnids and myriapods Hannah Wood has examined and analyzed hundreds of pelican spiders both in the field in Madagascar and through study of pelican spiders preserved in museum collections. Her analysis, focused on spiders of the Eriauchenius and Madagascarchaea genera, sorted the spiders she studied into 26 different species–18 of which have never before been described. Wood and colleague Nikolaj Scharff of the University of Copenhagen describe all 26 pelican spider species in the Jan. 11 issue of the journal Zookeys.

Wood says pelican spiders are well known among arachnologists not only for their unusual appearance, but also for the way they use their long “necks” and jaw-like mouthparts to prey on other spiders. “These spiders attest to the unique biology that diversified in Madagascar,” she said.

Pelican spiders are active hunters, prowling the forest at night and following long silk draglines that lead them to their spider prey. When a pelican spider finds a victim, it swiftly reaches out and impales it on its long, fang-tipped “jaws,” or chelicerae. Then it holds the capture away from its body, keeping itself safe from potential counterattacks, until the victim dies.

Today’s pelican spiders are “living fossils,” Wood says–remarkably similar to species found preserved in the fossil record from as long as 165 million years ago. Because the living spiders were found after their ancestors had been uncovered in the fossil record and presumed extinct, they can be considered a “Lazarus” taxon. In addition to Madagascar, modern-day pelican spiders have been found in South Africa and Australia–a distribution pattern that suggests their ancestors were dispersed to these landmasses when the Earth’s supercontinent Pangaea began to break up around 175 million years ago.

Madagascar is home to vast numbers of plant and animal species that exist only on the island, but until recently, only a few species of pelican spiders had been documented there. In 2000, the California Academy of Sciences launched a massive arthropod inventory in Madagascar, collecting spiders, insects and other invertebrates from all over the island.

Wood used those collections, along with specimens from other museums and spiders that she collected during her own field work in Madagascar, to conduct her study. Her detailed observations and measurements of hundreds of specimens led to the identification of 18 new species–but Wood says there are almost certainly more to be discovered. As field workers continue to collect specimens across Madagascar, “I think there’s going to be a lot more species that haven’t yet been described or documented,” she said.

The spiders Wood personally collected, including holotypes (the exemplar specimens) for several of the new species, will join the U.S. National Entomological Collection at the Smithsonian, the second-largest insect collection in the world, where they will be preserved and accessible for further research by scientists across the globe.

All of the pelican spiders that Wood described live only in Madagascar, an island whose tremendous biodiversity is currently threatened by widespread deforestation. The new species add to scientists’ understanding of that biodiversity, and will help Wood investigate how pelican spiders’ unusual traits have evolved and diversified over time. They also highlight the case for conserving what remains of Madagascar’s forests and the biodiversity they contain, she says.

Seven new spider species from Brazil named after 7 famous fictional spider characters

Several literary classics from the fantasy genre are further immortalised and linked together thanks to a Brazilian research team who named seven new spiders after them.

Spider characters from A Song of Ice and Fire, Harry Potter, The Lord of the Rings, The Silmarillion, H. P. Lovecraft’s The Call of Cthulhu and the children’s favourite Charlotte’s Web and Little Miss Spider each gave a name to a new small cave-dwelling six-eyed spider inhabiting northern Brazil.

Discovered in iron caves across the state of Pará, northern Brazil, the new species belong to the same Neotropical genus Ochyrocera. They are described in a new research article published in the open access journal ZooKeys by Dr Antonio Brescovit, Dr Igor Cizauskas and Leandro Mota – all affiliated with Instituto Butantan, Sao Paulo.

Interestingly, while all seven previously unknown species prefer staying in the shadows underground, none of them has the adaptations characteristic for exclusively cave-dwelling organisms, such as loss of pigmentation and reduced or missing eyes. They are classified as edaphic troglophile species, which means that they are capable of completing their life cycle away from sunlight, but are not bound to the deepest recesses. Often crawling near the surface, they can even be spotted outside the caves. To describe the species, the scientists collected about 2,000 adult specimens following a 5-year series of field collection trips.

The list of ‘fantasy’ spiders begins with Ochyrocera varys named after Lord Varys from George R. R. Martin’s book series A Song of Ice and Fire. Lord Varys is also known as the Spider because of his manipulative skills and ability to ‘weave’ and command his networks of eyes-and-ears across two continents.

The name of Ochyrocera atlachnacha refers to the Spider God Atlach-Nacha from the universe created by H. P. Lovecraft. Atlach-Nacha is a giant spider with a human-like face which lives in the caves beneath a mountain and spins a web believed to link the world with the Dreamlands.

Two species are named after spider characters from the classic works by J. R. R. Tolkien. Ochyrocera laracna is a species named after the well-known giant spider Laracna (Shelob in English) who attacks main characters Frodo and Sam on their way to Mordor in The Lord of the Rings’ second volume – The Two Towers.

On the other hand, the Brazilian spider’s sibling – Ochyrocera ungoliant – is linked to Laracna’s mother. Ungoliant appears in Tolkien’s book The Silmarillion, whose events take place prior to those of The Lord of the Rings’ second volume The Two Towers. According to the story, Ungoliant translates to Dark Spider in Elvish.

Another staple in the 20th-century fantasy literature, the Harry Potter series, written by J. K. Rowling, also enjoys the attention of the researchers. The species Ochyrocera aragogue is an explicit reference to the talking Aragog, who lives in the dark recesses of the Forbidden Forest. In the second volume of the series, Harry Potter and the Chamber of Secrets, he confronts Harry Potter and Ron Weasley.

The authors do not fail to pay tribute to much less violent spiders known from popular children books. David Kirk’s Little Miss Spider inspires the name of Ochyrocera misspider. The character is remembered with her words: “We have to be good to bugs; all bugs.”

The Ochyrocera charlotte species refers to Charlotte, the spider from E. B. White’s classic Charlotte’s Web who befriends the main character – Wilbur the pig.

It is highly likely that there are many species and populations of this group of spiders yet to be discovered in the Neotropics, since the lack of previous studies in the region. However, the area and its biodiversity are impacted by mining.

Family of scaffold web spiders increased with ~20% following discovery of 43 new species

Recent study into spider specimens collected from across China, Indonesia, Philippines, Singapore, Thailand, Vietnam and Madagascar over the past 15 years, revealed the striking number of 43 scaffold web spiders that have stayed hidden from science until now. By describing the new species in a paper published in the open access journal ZooKeys, scientists from Sichuan University and the Chinese Academy of Sciences increase the number of a scaffold web spider family (Nesticidae), known from around the world, with about twenty percents.

The studied family of scaffold web spiders is a relatively small group of arachnids, which can be found at almost any locality, apart from Siberia, Central Asia, Northern and Southern Africa and places at high latitude. Prior to the study of Drs Yucheng Lin, Francesco Ballarin and Shuqiang Li, the species counted 245 in total, 12 of which are extinct and known from fossils only. A curious peculiarity in these spiders is their comb of serrated bristles, located on their rear legs, used to pull silk bands for their webs.

Although large-scale taxonomic surveys of scaffold web spiders have long remained scarce, recently the interest towards spider research in China and Southeast Asia has seen a significant rise. Thus, over the last 15 years, Chinese, American and European arachnologists have carried out several surveys, ending up with precious samples. As a result, Dr Yucheng Lin and his team followed with deeper morphological and molecular studies to discover remarkable diversity.

In their work, the researchers have also established a new genus (Speleoticus) for five previously known, but misplaced species, which spend a lot of their time taking shelter in caves.

The majority of scaffold web spiders occur in temperate areas of the Holarctic realm, where the species tend to be medium-sized, long-legged, and prefer cave-like environments. The species found in the tropical and subtropical areas are, on the other hand, usually smaller, with shorter legs, and can be quite often spotted outside, where they crawl in forest litter, on grass, and under stones.

A new scorpion from California reveals hidden biodiversity in the Golden State

California is known for its high biological diversity. The state encompasses a wide variety of habitats, from temperate coastal scrub and cool redwood forests to high-elevation conifer forests and grasslands that are home to an equally diverse variety of plants and animals. Biologists have been intensively studying and characterizing the biodiversity of California for centuries.

Recent fieldwork by researchers Warren Savary and Rob Bryson uncovered a new species of scorpion in the foothills of the Sierra Nevada in northeastern California. It is related to several species in the genusPseudouroctonus, and is only the fourth new species of scorpion to be described from California in the past twenty years. The description is published in the open access journal ZooKeys.

The lead author, Warren Savary, is a field associate of the California Academy of Sciences and has been studying the scorpion diversity of California since the 1970s. He and a collaborator described a new species endemic to the White and Inyo Mountains in eastern California in 1991.

“California is home to a remarkable variety of scorpions,” says Savary. “However, the more I study them, the more I realize that we’ve only just scratched the surface. A lot of scorpion diversity remains to be described.” He and co-author Rob Bryson, a researcher at the University of Washington, have started using DNA to help better understand scorpion diversity.

“Scorpions have been around for a long time — over 400 million years — and many are quite similar in general appearance,” comments Bryson. “We can use DNA sequences to help us piece together how scorpions have evolved and how they are related. Despite looking similar, DNA often reveals that even assumed close relatives can be quite divergent.”

Savary and Bryson are working on publishing the descriptions of several other new species of scorpions from California. “2016 will be an exciting year for scorpion discoveries,” they promise.
