🥳 Here goes THE title in our New Species Showdown!

From the kingdom of plants, welcome the all-time crowd-favourite species ever described in a Pensoft journal!

Which one is the species that springs to mind when you think about the most awesome discoveries in recent times?

In an age where we more than ever need to appreciate and preserve the magnificent biodiversity inhabiting the Earth, we decided to go for a lighter and fun take on the work of taxonomists that often goes unnoticed by the public. 

From the ocean depths surrounding Indonesia to the foliage of the native forests of Príncipe Island and into the soils of Borneo, we started with 16 species described as new to science in journals published by Pensoft over the years. 

Out of these most amazing creatures, over the past several weeks we sought to find who’s got the greatest fandom by holding a poll on Twitter (you can follow it further down here or via #NewSpeciesShowdown).

Grand Finale – here comes the champion!

Truly, we couldn’t have a more epic final!

The two competitors come from two kingdoms, two opposite sides of the globe, and the “pages” of two journals, namely PhytoKeys and Evolutionary Systematics.

While we need to admit that we ourselves expected to crown an animal as the crowd-favourite, we take the opportunity to congratulate the botanists amongst our fans for the well-deserved win of Nepenthes pudica (see the species description)!

Find more about the curious one-of-a-kind pitcher plant in this blog post, where we announced its discovery following the new species description in PhytoKeys in June 2022:

Underground carnivore: the first species of pitcher plant to dine on subterranean prey

Back then, N. pudica gave a good sign about its worldwide web appeal, when it broke the all-time record for online popularity in a competition with all plant species described in PhytoKeys over the journal’s 22-year history of taxonomic papers comrpising over 200 issues.

What’s perhaps even more curious, is that there is only one species EVER described in a Pensoft-published journal that has so far triggered more tweets than the pitcher plant, and that species is the animal that has ended up in second place in the New Species Showdown: a tiny amphibian living in Peru, commonly known as the the Amazon Tapir Frog (Synapturanus danta). Which brings us once again to the influence of botanists in taxonomic research.

Read more about its discovery in the blog post from February 2022:

Frog with tapir-like nose found in Amazon rainforest

Another thing that struck us during the tournament was that there was only one species described in our flagship journal in systematic journal ZooKeys: the supergiant isopod Bathynomus raksasa, that managed to fight its way to the semi-finals, where it lost against S. danta.

This makes us especially proud with our diverse and competitive journal portfolio full of titles dedicated to biodiversity and taxonomic research!

The rules

Twice a week, @Pensoft would announce a match between two competing species on Twitter using the hashtag #NewSpeciesShowdown, where everyone could vote in the poll for their favourie.

Disclaimer

This competition is for entertainment purposes only. As it was tremendously tough to narrow the list down to only sixteen species, we admit that we left out a lot of spectacular creatures.

To ensure fairness and transparency, we made the selection based on the yearly Altmetric data, which covers articles in our journals published from 2010 onwards and ranks the publications according to their online mentions from across the Web, including news media, blogs and social networks. 

We did our best to diversify the list as much as possible in terms of taxonomic groups. However, due to the visual-centric nature of social media, we gave preference to immediately attractive species.

All battles:

(in chronological order)

Round 1
The first tie of the New Species Showdown was between the olinguito: Bassaricyon neblina (see species description) and the “snow-coated” tussock moth Ivela yini (see species description).
In the second battle, we faced two marine species discovered in the Indian Ocean and described in ZooKeys. The supergiant isopod B. raksasa (see species description) won against the Rose Fariy Wrasse C. finifenmaa (see species description) with strong 75%.
In the third battle, we faced two frog species: the tapir ‘chocolate’ frog described in Evolutionary Systematics (see species description) winning against the ‘glass frog’ described in Zookeys (see species description) with 73%.
With 62% of the votes, the two-species tournament saw the Harryplax severus crab grab the win against another species named after a great wizard from the Harry Potter universe: the Salazar’s pit viper, which was described in the journal Zoosystematics and Evolution in 2020. The “unusual” crustacean was described back in 2017 in ZooKeys. As its species characters matched no genus known to date, the species also established the Harryplax genus.
With the fifth battle in the New Species Showdown taking us to the Kingdom of Plants, we enjoyed a great battle between the first pitcher plant found to grow its pitchers underground to dine (see the full study) and the Demon’s orchid, described in 2016 from a single population spread across a dwarf montane forest in southern Colombia (read the study). Both species made the headlines across the news media around the world following their descriptions in our flagship botany journal PhytoKeys.
Next, we saw the primitive dipluran Haplocampa wagnelli (read its species description in Subterranean Biology) – a likely survivor of the Ice Age thanks to the caves of Canada – win the public in a duel against Xuedytes bellus (described in ZooKeys in 2017), also known as the Most cave-adapted trechine beetle in the world!
We had a close battle between the Principe Scops-owl Otus bikegila (see species description published in our ZooKeys earlier in 2022) and the blue-tailed Monitor lizard Varanus semotus (also first ‘known’ from the pages of ZooKeys, 2016). Being adorable species, but also ‘castaways’ on isolated islands in the Atlantic, they made great sensations upon their discovery. In fact, the reptile won with a single vote!
In the last battle of Round 1, the ‘horned’ tarantula C. attonitifer claimed the victory with a strong (80%) advantage from its competitor with a rebel name: the freshwater crayfish C. snowden (species description in ZooKeys from 2015). Described in African Invertebrates in 2019, the arachnid might be one amongst many ‘horned’ baboon spiders, yet there was something quite extraordinary about its odd protuberance. Furthermore, it came to demonstrate how little we know about the fauna of Angola:  a largely underexplored country located at the intersection of several ecoregions.
Round 2 – Quarter-finals
In the first quarter-final round, in the close battle, the isopod ’emerged’ from the ocean depths of Indonesia B. raksasa (species description in Zookeys from 2020) claimed the victory with just a few votes difference (58%!) from its competitor: lovely olinguito B. neblina, also described in Zookeys but back in 2013.
In the second round of the quarter-final, the tapir ‘chocolate’ frog S. danta (described in Evolutionary Systematics this year) claimed the victory with a significant advantage (69%) over its competitor crab H. severus described in Zookeys in 2017.
The third battle in Round 2 secured a place at the semi-finals for the only plant to get this far in the New Species Showdown. If you are dedicated to the mission of proving the plant kingdom superior: keep supporting Nepenthes pudica in the semi-finals and beyond!
In the meantime, read the full description of the species, published in our PhytoKeys in June.
The last quarter-final send the Angolan ‘horned’ tarantula to the next round. Described in African Invertebrates in 2019, its discovery would have likely remained a secret had it not been for the local tribes who provided the research team with crucial information about the curious arachnid.
Round 3 – Semi-finals
Curiously enough, by winning against the ‘supergiant’ isopod B. raksasa – also known around the Internet as the ‘Darth Vader of the seas’ – the Amazonian anuran S. danta outcompetes the last species in the New Species Showdown representing our flagship taxonomy journal: ZooKeys.

The charming anuran was described in February 2022 in Evolutionary Systematics, a journal dedicated to whole-organism biology that we publish on behalf of the Leibniz Institute for the Analysis of Biodiversity Change (LIB).
In a dramatic turn of events, the tight match between the Angolan tarantula C. attonitifer , whose ‘horn’ protruding from its back surprised the scientists because of its unique structure and soft texture, and the first pitcher plant whose ‘traps’ can be found underground in Borneo, ended up with the news that the New Species Showdown will be concluding with a battle between the kingdoms Animalia and Plantae! What a denouement!

The record-breaking plant was described in June 2022 in PhytoKeys: a journal launched by Pensoft in 2010 with the mission to introduce fast, linked and open publishing to plant taxonomy.
THE FINAL
And here we were at the finish line.
But why did we hold the tournament right now?

If you have gone to the Pensoft website at any point in 2022, visited our booth at a conference, or received a newsletter from any of our journals, by this time, you must be well aware that in 2022 – more precisely, on 25 December – we turned 30. And we weren’t afraid to show it!

Pensoft’s team happy to showcase the 30-year story of the company at various events this year.
Left: Maria Kolesnikova at the annual Biodiversity Information Standards (TDWG 2022) conference, hosted by Pensoft in Sofia, Bulgaria. Right: Iva Boyadzhieva at the XXVI International Congress of Entomology (ICE 2022) in Helsinki, Finland.

Indeed, 30 is not that big of a number, as many of us adult humans can confirm. Yet, we take pride in reminiscing about what we’ve done over the last three decades. 

The truth is, 30 years ago, we wouldn’t have been able to picture this day, let alone think that we’d be sharing it with all of you: our journal readers, authors, editors and reviewers, collaborators in innovation, project partners, and advisors. 

Long story short, we wanted to do something special and fun to wrap up our anniversary year. While we have been active in various areas, including development of publishing technology concerning open and FAIR access and linkage for research outcomes and underlying data; and multiple EU-supported scientific projects, we have always been associated with our biodiversity journal portfolio.

Besides, who doesn’t like to learn about the latest curious creature that has evaded scientific discovery throughout human history up until our days? 😉

By the time authors – who have acknowledged third-party financial support in their research papers submitted to a journal using the Pensoft-developed publishing platform: ARPHA – open their inboxes to the congratulatory message that their work has just been published and made available to the wide world, a similar notification will have also reached their research funder.

This automated workflow is already in effect at all journals (co-)published by Pensoft and those published under their own imprint on the ARPHA Platform, as a result of the new partnership with the OA Switchboard: a community-driven initiative with the mission to serve as a central information exchange hub between stakeholders about open access publications, while making things simpler for everyone involved.

All the submitting author needs to do to ensure that their research funder receives a notification about the publication is to select the supporting agency or the scientific project (e.g. a project supported by Horizon Europe) in the manuscript submission form, using a handy drop-down menu. In either case, the message will be sent to the funding body as soon as the paper is published in the respective journal.

“At Pensoft, we are delighted to announce our integration with the OA Switchboard, as this workflow is yet another excellent practice in scholarly publishing that supports transparency in research. Needless to say, funding and financing are cornerstones in scientific work and scholarship, so it is equally important to ensure funding bodies are provided with full, prompt and convenient reports about their own input.”

comments Prof Lyubomir Penev, CEO and founder of Pensoft and ARPHA.

 

“Research funders are one of the three key stakeholder groups in OA Switchboard and are represented in our founding partners. They seek support in demonstrating the extent and impact of their research funding and delivering on their commitment to OA. It is great to see Pensoft has started their integration with OA Switchboard with a focus on this specific group, fulfilling an important need,”

adds Yvonne Campfens, Executive Director of the OA Switchboard.

Festschrift for Dr Jason Londt at African Invertebrates invites submissions

African Invertebrates invites any submissions linked to Jason, new species descriptions, revisions of taxa he has worked on, or any work based on specimens he collected.

From 1976 to 1994, Jason Londt was Assistant Director at the Natal Museum (now KwaZulu-Natal Museum) in South Africa, publisher of the African Invertebrates journal. Then, he became Director before retiring in 2003.

During his career at the Museum and well after that, Jason described more than 570 species and 46 genera of insects from the Afrotropics. While the majority of his work was on the robber fly family (Asilidae), Jason also worked on hangingflies (Bittacidae) and ticks. He was also a prolific collector of many other insects, still kept in the collection of the KwaZulu-Natal Museum. 

Dr Jason Gilbert Hayden Londt

Jason’s fieldwork was extensively targeting the diverse habitats in South Africa: from the subtropical coast of KwaZulu-Natal, the grasslands in the Midlands around Pietermaritzburg – where the museum is based – and further north in the Highveld, to the higher elevations of the Drakensberg Mountains bordering Lesotho, and from the Succulent and Nama Karoo, to the diverse Fynbos habitats along the south-western coast of South Africa. Additional major fieldwork took place in Namibia, Kenya, Malawi, and to a lesser extent: Eswatini (Swaziland) and Cote d’Ivoire. In addition to utilising the collected material for taxonomic work, Jason also used his field trips to publish behavioural observations and prey selection of Asilidae species.

To celebrate Jason’s career achievements and his 80th birthday, African Invertebrates will be publishing a Festschrift in his honour in April 2023. We invite any submissions linked to Jason, new species descriptions, revisions of taxa he has worked on, or any work based on specimens collected by Jason.

This issue will be edited by Dr Torsten Dikow (Smithsonian National Museum of Natural History, USA), Dr Kirstin Williams (KwaZulu-Natal Museum) and Dr John Midgley (KwaZulu-Natal Museum).

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.

Conservation and nameless earthworms: Assessors in the dark?

Species that live exclusively in a single region are at a particular risk of extinction. However, for them to be protected, thorough assessments of the environmental impacts need to be performed.

There are more than 100 earthworm species living in the soil and dead wood of KwaZulu-Natal Province, South Africa. Most of them live exclusively in small regions in the province, which makes them extremely vulnerable.

To scientists Dr Adrian J. Armstrong, Ezemvelo KZN Wildlife, and Ms Thembeka Nxele, KwaZulu-Natal Museum, the problem is twofold. Firstly, they note that the expression “out of sight, out of mind” is very suitable for the case of the endemic earthworms in South Africa. Secondly, they point out that the lack of common names for these species is a stumbling block that hinders their inclusion in conservation assessments.

As a result, the researchers try to rectify this situation by assigning standardised English names to the endemic earthworms in KwaZulu-Natal. Their article is published in the open access journal African Invertebrates.

Scientific names are often intractable to non-specialists, and the lack of common names leaves environmental assessors in the dark when they need to figure out which earthworms may occur at a development site. In the meantime, it has been found that about 50% of the native vegetation in KwaZulu-Natal has already been removed as a result of infrastructure construction and the figure is rising.

“The indigenous earthworms generally don’t survive in developed areas,” say the authors.

For instance, the informal use of an English name (green giant wrinkled earthworm) for the species Microchaetus papillatus, has facilitated the inclusion of this species in environmental impact assessments in KwaZulu-Natal.

While the green giant wrinkled earthworm does occur in a relatively large and rapidly developing area in KwaZulu-Natal, other species live in smaller areas that have been urbanised even more.

The extinction of these earthworms is not only undesirable from the point of view of biodiversity advocates – the role of this group of soil organisms is impossible to replace fully with non-native earthworms. For example, some of the large indigenous earthworms (more than 1 m in length) burrow much deeper than the non-native species, thereby enriching and aerating the soil at greater depth.

The authors are hopeful that by giving the indigenous earthworms in KwaZulu-Natal common names, the threatened and endemic species will be conserved through inclusion in environmental impact assessments. Furthermore, they believe that earthworms could draw attention to the areas where they occur whenever a choice for new protected areas is to be made.

Assassins on the rise: A new species and a new tribe of endemic South African robber flies

Discovery of a new species of assassin flies led to the redescription of its genus. This group of curious predatory flies live exclusively in South Africa, preferring relatively dry habitats. Following the revisit, authors Drs Jason Londt, KwaZulu-Natal Museum, South Africa, and Torsten Dikow, Smithsonian Institution National Museum of Natural History, USA, publish updated information about all species within the genus, now counting a total of seven species, and also establish a new tribe. Their study is published in the open access journal African Invertebrates.

The family of assassin flies (Asilidae), also known as robber flies, are curious insects, which have received their common name due to their extremely predatory behavior. The assassin flies prey on a great variety of insects, including beetles, moths, butterflies, wasps, other flies, as well as some spiders, as early as their juvenile stage of development. When hunting, they would ambush their prey and catch it in flight. Then, they would pierce the victim with a short and strong proboscis, while injecting venom. Once in the body of the prey, it quickly dissolves the insides, so that the assassin fly can suck them out.

The published study was spawned by the collection of new specimens of previously described assassin flies of the species Trichoura tankwa by the junior author in December 2015. These specimens could not be easily identified and so the authors started to look at all available specimens in natural history museums.

image-2The new species, called Trichoura pardeos, was discovered in Tierberg Nature Reserve by the authors in 2004, a small conservation area located on the north banks of the Gariep River in the Northern Cape province of South Africa. The habitat comprises almost entirely a large rocky hill, where the vegetation is scarce and dominated by drought-resistant plants, such as aloes. The fly is predominantly red-brown in colour, with silvery, white and yellowish markings.

Having noted morphological variation between the species inhabiting areas with differently timed yearly rainfalls, the entomologists suggest that two groups within the studied genus have adapted to these different patterns in western and eastern South Africa. They also expect that species representing Trichoura could be also dwelling in Namibia, Botswana, Mozambique and possibly Zimbabwe.

Unfamiliar bloodline: New family for an earthworm genus with exclusive circulatory system

New earthworm family, named Kazimierzidae, has been established for a South African indigenous genus of 21 species. Although the circulatory system in the group has been regarded as exclusive upon their original description in 2006, their raising to a family status have only recently been confirmed by a research team from South Africa.

Scientists Mrs Thembeka Nxele, Dr Danuta Plisko (original discoverer of the genus Kazimierzus, now known as family Kazimierzidae), affiliated with Natal Museum (NMSA), Oliver Tendayi Zishiri, affiliated with University of KwaZulu-Natal, and Dr Taro Mwabvu, University of Mpumalanga, looked into the earthworm collection at the NMSA, as well as the type material and the available literature. Their study is published in the open access journal African Invertebrates.

When compared to the rest of the members in the family Microchaetidae, where the former genus had been placed, the studied earthworms show a number of distinct characters, including an “exclusive” circulatory system. In these species it is a simple single tube stretching along the whole body.

All 21 earthworm species, now members of the newly established family, can only be found in small areas restricted in the western and south-western Atlantic coast of South Africa. These locations have long been known for their endemic invertebrates and diverse flora.

In their paper, the authors note that it is actually the restricted range, and therefore the specific ecological requirements, that might have led these earthworms to become that different from other species. Their distribution and, hence, poor dispersal ability, are also the reason why the newly established group would be particularly vulnerable if the habitat is transformed.

“The species distribution of earthworms in Southern Africa is presently poorly known hence the urgency for extended study on earthworm diversity and their distribution patterns,” point out the scientists. “Extensive earthworm collection in the western Atlantic coast may bring more data on this and other taxa.”
