Not ugly but lovely: 100 ZooKeys papers on spiders co-authored by Shuqiang Li

Shuqiang has published 51 new genera and 677 new species in 100 ZooKeys papers.

Last week, on Friday, 6 October 2023, a research article entitled “One new genus and four new species of Liocranidae Simon, 1897 (Arachnida, Araneae) from China and Vietnam” by Chang Chu, Shuqiang Li, Yanbin Yao, Zhiyuan Yao was published. This is the 100th paper published in ZooKeys co-authored by Shuqiang Li, a leading spider specialist from the Chinese Academy of Sciences in Beijing, China. Shuqiang’s first ZooKeys paper was published on December 18, 2012. Until last Friday, Shuqiang has published 51 new genera and 677 new species in 100 ZooKeys papers.

Shuqiang started his scientific career as a spider taxonomist, with his first paper on the Linyphiidae of China published in 1987, followed by a series of revisions of known Chinese and Asia spider species. To date, he has documented more than 2,000 new species.

He is also a proficient professor in the University of Chinese Academy of Sciences and has mentored more than 30 PhD students from China, Vietnam, and Italy, and another three M.Sc. students from Kenya and Malaysia. Most of his former Chinese PhD students have since become full professors. Shuqiang has been the Secretary of the Asian Society of Arachnology since 2012 and President of the Arachnology Society of China since 2018.

Many people see spiders as ugly due to their multiple legs, hairy bodies, and sometimes venomous fangs, but this appearance serves a purpose in their survival and adaptation to their environment. “Spiders are lovely animals”, Shuqiang said to us. He focuses mostly on fine spider structures. For example, he used spider copulatory organs (male palp and female epigyne) to study species taxonomy. “Interspecies mating is not easy due to difference in copulatory organs,” he says. He and his team members are also focusing on the origin of spider organs.

Persian Gold Tarantula: a new species from Iran for Tarantula Appreciation Day 2023

Its “woolly, golden hairs” were one of the features so unique it was not necessary for additional individuals to be collected

Guest blog post by Dr Alireza Zamani (@Arachno_AZ)

In the latest issue (1174th) of the scientific open-access journal ZooKeys, you can find our paper describing a new species of tarantula (family Theraphosidae) found in northwestern Iran. 

This species belongs to Chaetopelma, a relatively small genus, distributed in Crete, Sudan, and the Middle East, and one of the only two tarantula genera inhabiting the Mediterranean region. 

Our discovery is significant for several reasons. Firstly, it marks the first record of this genus in Iran and the third known species of tarantulas in this country. Additionally, it extends the known range of Chaetopelma spiders by almost 350 km eastwards. 

We named this species Chaetopelma persianum, paying homage to its occurrence in Iran, which has historically been known as Persia. As a potential common name, we suggest “Persian Gold Tarantula”, where we are also making a reference to the “woolly, golden hairs’’ on its carapace.

For the purpose of our study, we only had one specimen: a female with a leg span of almost 9 cm, available. Yet, its distinct characteristics allowed us to confidently differentiate it from other known Chaetopelma species. 

This tarantula is an obligate burrower and inhabits high elevations in well-vegetated mountainous regions of the northern Zagros Mountains. The holotype specimen was collected from a self-made ground burrow on sloped rocky ground, amidst sparse low vegetation and grasses. 

It all started with local nature enthusiast Mehdi Gavahyan, who photographed a wandering male and sent me the photo. When I figured it was most likely an undescribed species, I asked him to team up with Amir Hossein Aghaei, a nature enthusiast and a friend of mine, and send me specimens of these spiders for further examination. Unfortunately, they only managed to collect that one female. However, it turned out to be enough for us to describe the Persian Gold Tarantula!

Additionally, thanks to local citizen scientists and naturalists, we later also got hold of photos of another two males of the same genus, taken very close to the type locality of the new species: one in Sardasht in West Azerbaijan Province of Iran, and the other in the surroundings of Sulaymaniyah in Iraq. While it is highly probable that both these males belong to Ch. persianum, this cannot be confirmed until further examination of collected material from both sexes is conducted.

During our research, we also noted that one species of Chaetopelma described from Cameroon is misclassified and should be transferred to another genus. However, this transfer is pending until the type material undergoes examination.

Looking ahead, we believe that more comprehensive investigations employing integrative methods would greatly benefit the taxonomy of Chaetopelma

For example, Ch. olivaceum, a species with seven junior synonyms and one of the broadest ranges within the entire family, covering an area of approximately 1,493,978 km2, might potentially have cryptic species within its range. Moreover, the disjunct distribution of Ch. olivaceum in Turkey, where it occurs both in the southern regions and as far north as Istanbul, raises the possibility of distinct species status for the latter population, which is geographically isolated from the rest of the recorded occurrences. Integrative studies incorporating molecular data could offer insights into this. 

Additionally, further collection efforts in lesser-sampled or completely unexplored regions, such as Saudi Arabia, Syria, Iraq, eastern Turkey and western Iran, could lead to the discovery of additional Chaetopelma species or records. These findings would be instrumental in gaining a more comprehensive understanding of the taxonomy and distribution of this genus.

Guest blog post: New ectoparasite records from Honduras came from bats recorded since 2015

Guest blog post by Manfredo Alejandro Turcios-Casco

Since its foundation in 2015, the research team “The Big Bat Theory” has filled important information gaps regarding bats and their ectoparasites in Honduras. We started as just bachelor students mist-netting bats in our university (Universidad Nacional Autónoma de Honduras- UNAH) in our free time. Then we studied a lot about their natural history, distribution, and ecology, and, without any financial support, we started to travel the country studying bats.

The early years of “The Big Bat Theory” research group

At that time, we did not know that many of those records, in the future, would be important for Honduras. After saving some money, we travelled to different departments of Honduras such as Francisco Morazán, Valle, Gracias a Dios, Comayagua, and Santa Bárbara. Then we found support from Marcio Martínez to get to know La Mosquitia, and we started studying bats in unexplored regions. Because of this initiative, we collaborated with bat ectoparasite specialist Gustavo Graciolli and bat specialist Richard Laval, which resulted in the publication of our research in the open-access, peer-reviewed journal Check List.

As a result of this project, we were able to register for the first time the Spinturnicidae family in Honduras with the species Periglischrus iheringi and P. ojastii, a new record of Basilia ortizi (Nycteribiidae), Aspidoptera delatorrei, Strebla matsoni (found hosting Artibeus jamaicensis for the first time), and Neotrichobius bisetosus (Streblidae). The latter, previously only known from Venezuela, is the record with the northernmost locality published to date. We managed to increase the number of species of bat ectoparasites in Honduras to 48, which is 33 more than in Paraguay and 65 less than in Peru.

Species of ectoparasites recorded for the first time in Honduras: A) Periglischrus iheringi (Spinturnicidae); B) Periglischrus ojastii (Spinturnicidae); C) Aspidoptera delatorrei (Streblidae); D) Trichobius yunkeri (Streblidae); E) Basilia ortizi (Nycteribiidae); F) Neotrichobius bisetosus (Streblidae); G) Strebla matsoni (Streblide).

We definitely consider that this still misunderstood group needs more research effort locally and in general. Considering the lack of knowledge, the chances of discovering new species for the region, new records for the country or region, as well as new discoveries about the relationship and interactions with their hosts, are high. The number of bat species registered for Honduras is a predictor of the number of ectoparasite species that may exist. We also consider “La Reserva de la Biosfera del Río Plátano” an important site for the study of ectoparasites of bats. This is the most important area in Honduras for bat research and conservation, not only because of its high biodiversity, but also because it is a poorly studied region.

“We are very motivated to have carried out this study on new records of ectoparasites in bats, since it is the first investigation we do on this taxon, but we are sure that it will not be the last, since we have already begun to collect new data in collaboration with experts on this topic. We are sure that new discoveries still await us in this area, and we are eager to make new contributions and enrich the information on this taxon in Honduras and the world.”

Two species and a single name: ‘Double identity’ revealed in a venomous banana spider

Phoneutria boliviensis in the Peruvian Amazon

Spiders from the genus Phoneutria – also known as banana spiders – are considered aggressive and among the most venomous spiders in the world, with venom that has a neurotoxic action. These large nocturnal spiders usually inhabit environments disturbed by humans and are often found in banana plantations in the Neotropical region. 

One of these spiders, P. boliviensis, is a medically important species widely distributed in Central and South America, whose behaviour, habitat, venom composition, toxicity and bites on humans have already been paid considerable attention in previous research work. Nevertheless, after examining a large pool of museum specimens, biologists from The George Washington University (N. Hazzi and G. Hormiga) began to wonder if samples named P. boliviensis were actually belonging to one and the same species. 

Everything started when N. Hazzi was examining specimens of banana spiders identified in the past by experts as P. boliviensis. The research team quickly realized that the morphological features currently used to identify this species were not sufficient. Then, they discovered two well-defined morphological groups of P. boliviensis that were separated by the Andean mountain range, a geographic barrier that separates many other species.

To prove that these two “forms” were different species, the authors conducted fieldwork in the Amazon, Andes, and Central America, collecting specimens of these venomous spiders to explore if the genomic signal also suggests two species. They discovered that genetic differences separating these two forms were similar compared to the genetic differences separating other recognized species of banana spiders. Using morphological, genomic and geographic distribution data, the authors concluded that P. boliviensis represents not a single species, but two different ones. They uncovered that the true P. boliviensis was only found in the Amazonian region, and the second species, P. depilata (an old name revalidated by the research team), was found in the Andes, Chocó and Caribbean regions. Their findings are published in the open-access, peer-reviewed journal ZooKeys.

To obtain more distribution records for these species, the research team used the citizen science platform iNaturalist. Since the two species are among the few spiders that can be identified using only images, the platform turned out to be a very helpful tool. Data submitted by the iNaturalist community helped identify where the two species of Phoneutria are found. Curiously enough, for these two species, iNaturalist presented higher and more widely distributed records than the scientists’ own database. 

“To our knowledge, this is the first study that has used iNaturalist to gather occurrence records on venomous species to estimate distribution models,”

the researchers say.

This is how the two spiders can be distinguished using only photographs: P. boliviensis has two lateral white-yellow bands in the anterior area of the carapace, while P. depilata has four series of yellow dots in the ventral side of the abdomen. In addition, for P. depilata’s identification, information is needed on where the image was taken, because this is the only species of Phoneutria found in the Andes, Chocó, and Central America. However, the most reliable approach to identify these species requires examination under a stereomicroscope.  

Interestingly, P. depilata has been mislabeled as P. boliviensis throughout many studies, including works on venom composition and toxicity, ecology, geographic distribution, and human epidemiology of bites. There have been human bite records of this species reported in Costa Rica and in banana plantations in Colombia, most of them with mild to moderate envenomation symptoms. Except for brief anecdotal mentions by field explorers in the Amazon, little is known about P. depilata.

The study provides detailed diagnoses with images to distinguish both species and distribution maps. 

“This valuable information will help identify risk areas of accidental bites and assist health professionals in determining the identity of the species involved, especially for P. depilata. This is a significant discovery that will affect studies about toxicology, opening new opportunities to compare the venom composition and the effect of these two species,” the authors conclude.

Trendy on eight legs: Jumping spider named after fashion czar Karl Lagerfeld


Newly described ‘brushed’ jumping spider species Jotus karllagerfeldi and its famous namesake: fashion icon and designer, creative director, artist, photographer and caricaturist Karl Lagerfeld (1933-2019).

New to science species of Australian jumping spider was named after Hamburg-born fashion icon Karl Lagerfeld (1933-2019) after the arachnid reminded its discoverers of the designer. Intrigued by its distinct ‘downplayed’ black-and-white colours, the Hamburg-Brisbane-Melbourne team likened the spider’s appearance to Lagerfeld’s trademark style: his white hair and Kent collar that contrasted with the black sunglasses and gloves.

New to science species of Australian jumping spider was named after Hamburg-born fashion icon Karl Lagerfeld (1933-2019) after the arachnid reminded its discoverers of the designer. Intrigued by its distinct ‘downplayed’ black-and-white colours, the Hamburg-Brisbane-Melbourne team likened the spider’s appearance to Lagerfeld’s trademark style: his white hair and Kent collar that contrasted with the black sunglasses and gloves.

Thus, the curious species, now officially listed under the name Jotus karllagerfeldi was described in the open-access journal Evolutionary Systematics by Dr Danilo Harms of the Center for Natural History of the University of Hamburg (CeNak), Dr Barbara Baehr, Queensland Museum (Brisbane, Australia) and Joseph Schubert, Monash University (Melbourne).

Typically, the members of the jumping spider genus Jotus demonstrate striking red and blue colours.

When compared with other members in the ‘brushed’ jumping spider genus Jotus, the novel species clearly stands out due to its black-and-white legs and tactile organs (pedipalps), whereas the typical representative of this group demonstrates striking red or blue colours.

“The animal reminded us with its colours of the reduced style of Karl Lagerfeld. For example, we associate the black leg links with the gloves he always wore”, Danilo Harms explains.

In fact, what was to be now commonly referred to as Karl Lagerfeld’s Jumping Spider was identified amongst specimens in the Godeffroy Collection. Kept at CeNak, the historical collection was originally compiled by the inquisitive and wealthy tradesman from Hamburg Johann Cesar Godeffroy, who financed several expeditions to Australia back in the 19th century. Here, the research team identified another link between Australia, Godeffroy, Hamburg and Jotus karllagerfeldi.

Besides the tiny (4 to 5 mm) arachnid, whose pedipalps resemble a white Kent collar, the scientists describe another seven new to science species and add them to the same genus. Two of those, Jotus fortiniae and Jotus newtoni, were also named after inspirational figures for their hard work and creativity: educator, molecular biologist and science communicator Dr Ellen Fortini (Perth College, Western Australia) and keen naturalist and photographer Mark Newton. All novel species were found either in the Godeffroy Collection or amongst the jumping spiders housed at Queensland Museum.

Surprisingly, even though the genus Jotus comprises numerous species found all over Australia, there is not much known about these spiders. An interesting feature, according to the scientists behind the present study, are the huge telescopic eyes, which allow for spatial vision. The Jotus species need this ability in foraging, since they do not weave webs, but rather hunt in the open. Thus, they have evolved into extremely fast and agile hunters, capable of jumping short distances.

Curiously, back in 2017, the team of Barbara and Danilo, joined by Dr Robert Raven from Queensland Museum, described another previously unknown, yet fascinating species: a water-adapted spider, whose sudden emergence at the coastline of Australia’s “Sunshine State” of Queensland during low tide in January brought up the association with reggae legend Bob Marley and his song “High Tide or Low Tide”. The species, scientifically known as Desis bobmarleyi, was also published in Evolutionary Systematics.

As uniform as cloned soldiers, new spiders were named after the Stormtroopers in Star Wars

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 (AnisaspisParatropis and Stormtropis).

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.”

Lichens growing on an oak trunk at the study site in central Spain.

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.

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

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?

submitting

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.”
