A hair’s breadth away: New tarantula species and genus honors Gabriel García Márquez

With its extraordinary defensive hairs, a Colombian tarantula proved itself as not only a new species, but also a new genus. It is hypothesised that the new spider is the first in its subfamily to use its stinging hairs in direct attack instead of ‘kicking’ them into the enemy.

Described in the open access journal ZooKeys by an international research team, led by Carlos Perafán, University of the Republic, Uruguay, the name of the new spider genus honours an indigenous people from the Caribbean coast region, whose language and culture are, unfortunately, at serious risk of extinction. Meanwhile, its species’ name pays tribute to renowned Colombian author and Nobel laureate for his novel ‘One Hundred Years of Solitude’ Gabriel García Márquez.

The new tarantula, formally called Kankuamo marquezi, was discovered in Sierra Nevada de Santa Marta, Colombia. When examined, the arachnid showed something extraordinary about its defensive hairs and its genitalia. The hairs were noted to form a small oval patch of lance-shaped barbs, hypothesised by the scientists to have evolved to defend their owners by direct contact.

On the other hand, when defending against their aggressors, the rest of the tarantulas in this subfamily need to first face the offender and then vigorously rub their hind legs against their stomachs. Aimed and shot at the enemy, a ball of stinging hairs can cause fatal injuries to small mammals when landed into their mucous membrane (the layer that covers the cavities and shrouds the internal organs in the body). Once thrown, the hairs leave a bald spot on the tarantula’s belly.

“This new finding is a great contribution to the knowledge of the arachnids in Colombia and a sign of how much remains to be discovered,” point out he authors.

“The morphological characteristics present on Kankuamo marquezi open the discussion about the phylogenetics relationship between subfamilies of Theraphosidae tarantulas and the evolutionary pressures that gave rise to the urticating hairs.”

Celebration time: ZooKeys releases its 600th issue

With what already sounds like an annual tradition at this time of the year, we are delighted to announce yet another milestone that ZooKeys just reached. Our 600th issue is now out and we are just as proud with it as we were exactly five years and a month ago, when we printed out our first three-digit issue number on a ZooKeys cover.

However, we feel nowhere near getting tired of counting pages, covers and issues, nor do we believe this will ever going to happen. Quite the contrary, every year we take more and more pleasure in adding new achievements next to the name of ZooKeys and Pensoft.

Last year was no exception. During the past 13 months, we published a total of 673 articles, including research findings spectacular enough to reach out to not only the zoological fellowship, but to the wide audience from around the world. While our Impact Factor keeps on increasing, according to the figures Thomson Reuters released last week, we are gratified to observe our progressively growing impact on both the scholarly and the popular-science front.

Thanks to the discoveries, which found a suiting publication partner in ZooKeys, our authors and us made a lot of big headlines in outlets such as National Geographic, Science, CNN, BBC, Sky News, New York Times, Deutsche Welle, Der Standard, DR, Washington Post, Fox News, Huffington Post, The Guardian, NBC News, and a lot more. We had a bit of everything: record-breakers, species given mystic or splashy names and others bearing nerdy ones. Together, we also gave public voice to serious conservation issues, calling for immediate action.

Last June, we introduced you to the Hades centipede, known to be the world’s deepest-dwelling species of its kind. Who knew that the entrance to the Underworld is located in a Croatian cave?

Later on, in November, published with us snail species Acmella nana broke the World record for the tiniest land snail. Moreover, this happened only about a month after we published the previous ‘prizewinner’ Angustopila dominikae, and that one was already tiny enough to fit 10 of its shells within the eye of a needle at the very same time!

Our pages, which have been and always will be openly available to read for anyone who is online, were also the first to let you know about the existence of the Johnny Cash tarantula, the (Edward) Snowden crayfish, the two daddy longlegs: Smeagol and the ‘Master-of-the-crypt’ Behemoth, the Chewbacca beetle and the Brad Pitt wasp, among many others.

About two months ago, graduate student Madhu Chetri spotted the ancient Himalayan woolly wolf in Nepal. The new knowledge about the beautiful and, sadly, Critically Endangered carnivore, which he acquired, will hopefully help in preventing its otherwise imminent extinction.

In the meantime, Deutsche Welle (DW) featured our Zorro fish along with the eight-legged Johnny Cash’s namesake in their rank list of the 7 “newcomer” species of the year.

While being in the spotlight is definitely a gratifying feeling, we also indulge in our successes achieved far from the eyes of the public, although we are certain that our authors will be just as excited to hear about. Such an accomplishment is our recently sealed partnership with open digital repository Zenodo, who are helping us, along with the rest of the journals, published by Pensoft, to keep our research findings safe and easily accessible by archiving all our articles in both PDF and XML format on the date of publication.

However, let’s not forget that nothing of all the above would be what it is without our authors, editors and reviewers, who have always done their best to keep ZooKeys at the World’s top open access academic journals. We’d especially like to thank our Most active authors, editors and reviewers for being substantial part of ZooKeys.

End of an era: New sixth volume Research on Chrysomelidae the last with its original editors

The new and sixth volume of Research on Chrysomelidae consists of five research articles devoted to the latest findings about the amazing family of over 37,000 leaf beetle species from more than 2,500 genera. Among the studies, conducted by authors from all around the world, there is a new species of potentially dangerous legume-feeding pest, as well as new information regarding the life cycle,ecological interactions, species richness factors and taxonomy of some leaf beetles.

The latest volume devoted to one of the most intriguing beetle families also marks a turning point for the entomologists sharing special fondness for the leaf beetles. While the “spiritus rector” of the Chrysomelidae research community, Prof Pierre Jolivet resigned from his position last year, now Dr Jorge Santiago-Blay is also stepping down from the editorial board.

The third of the original trio, Prof Michael Schmitt, Ernst-Moritz-Arndt-Universität, takes the opportunity to look back to the beginning of the community and pay tribute to his long-year colleagues in his Editorial. He also confirms that the series, by now traditionally published in the open access journal ZooKeys, is far from over.

“I thank Jorge Santiago-Blay from the bottom of my heart for his tireless engagement in fostering leaf beetle research and his friendship, and wish him All the Best for whatever he may entertain in the future,” read his words.

In his short publication accompanying the five-piece issue, Prof Michael Schmitt recalls the very beginning of his team’s existence, started in 2001. He does not omit to note the numerous obstacles surrounding the first issues. At a point, having completed the enormous book “The green book – New Developments in the Biology of the Chrysomelidae”, comprising 62 chapters by 111 authors, as well as the first two volumes of Research on Chrysomelidae, they were made to drop the series due to unsatisfying selling numbers.

However, everything changed after the conversation Prof Pierre Jolivet and Prof Lyubomir Penev, Pensoft Publishers, had at the 9th European Congress of Entomology, held in Hungary in 2010. There they agreed to publish the next Research on Chrysomelidae volume as a special issue in ZooKeys, one of Pensoft’s journals.

Shortly after, the collaboration turned out so successful that it is now resulting in a fourth consecutive special issue. In the meantime, last December, the 30th anniversary of Symposia on Chysomelidae was celebrated in another leaf beetle-themed ZooKeys issue. Moreover, the next issue is already planned. It will cover the proceedings of the 9th International Symposium on Chrysomelidae and will be edited by Prof Michael Schmitt and Dr Caroline Chaboo, University of Nebraska State Museum, USA.

“The present volume is the fourth, but certainly not the last, published by Pensoft. Although the pullout of Pierre Jolivet and Jorge Santiago-Blay marks a crucial cut in the history of Research on Chrysomelidae, I understand the reasons of their decision to step down,” concludes Prof Michael Schmitt. “I hope and wish that the series will prosper and remain accepted as a forum of leaf beetle research by the community of Chrysomelidae enthusiasts all over the world.”

The Godzilla goby is the latest new species discovered by the Smithsonian DROP project

As part of the Deep Reef Observation Project (DROP), initiated by the Smithsonian Institution, a new goby fish species was discovered in the southern Caribbean. Living at depths greater than conventional SCUBA divers can access, yet too shallow to be of interest for deep-diving submersibles, the fish will now be known under the common name of the Godzilla goby.

Its discoverers Drs Luke Tornabene, Ross Robertson and Carole C. Baldwin, all affiliated with the Smithsonian Institution, have described the species in the open access journal ZooKeys.

Formally called Varicus lacerta, the species name translates to ‘lizard’ in Latin and refers to the reptilian appearance of the fish. Its prime colors are bright yellow and orange, while the eyes are green.

The new goby also has a disproportionately large head and multiple rows of recurved canine teeth in each jaw. This is also why the research team has chosen the common name of the Godzilla goby.

Apart from its lovely coloration, the new fish stands out with its branched, feather-like pelvic-fin rays and the absence of scales.

The scientists caught the Godzilla goby thanks to the manned submersible Curasub, which had already helped in discovering several species over the course of the project. Last year, Drs Ross Robertson and Carole Baldwin had another new goby published in ZooKeys. That time, they even named it after the submersible. Earlier this year, the DROP team also described nine additional new species, many of which were collected by the Curasub.

The manned submersible Curasub reaches depths up to 300 m in search of tropical marine fishes and invertebrates. As a result, it provides new information on the fauna that inhabits poorly studied deep-reef ecosystems.

The sub relies on two hydraulic arms, one equipped with a suction hose, and the other designed to immobilize the fish with an anaesthetizing chemical. That way, not only do the researchers gather live specimens, which once collected, are deposited into a vented acrylic cylinder attached to the outside of the sub, but also individuals suitable for critical DNA analyses.

More than just hippos and crocs: The hidden biodiversity of the iSimangaliso Wetland Park

iSimangaliso Wetland Park, a UNESCO World Heritage Site in the sub-tropical north-eastern corner of South Africa has become famous for its birdlife, crocodiles and hippopotamuses that frolic in the warm estuarine waters of Lake St Lucia. However, there’s more to the park than the “big and hairy”, according to aquatic ecologist Prof Renzo Perissinotto at Nelson Mandela Metropolitan University (NMMU) in Port Elizabeth, whose research is published in the open access journal ZooKeys.

“Although we have spent several decades focusing on life in the estuary, we only recently came to realise that much of the wealth of biodiversity in the park exists in the small freshwater ponds that are adjacent to, but disconnected from, the main lake,” he says.

The St Lucia lake itself is generally brackish and is located on a large sandy expanse known as the Maputaland coastal plain. Dotted across the landscape of this coastal foreland are numerous temporary freshwater ponds, seeps and small streams that are disconnected from the brackish lake body.

A team of self-proclaimed “beetle nerds”, led by Prof Perissinotto, got together from NMMU and Plymouth University (UK) and uncovered more species of water beetles in these tiny water bodies than is known for any other similar-sized region in southern Africa.

The beetle collection trips were done over a 16-month period and revealed 68 species of predaceous water beetles alone, termed more formally as the “Hydradephaga”. The iSimangaliso Wetland Park houses approximately 20% of the total number of known species for this beetle group in the whole of southern Africa. Of the species collected during their expeditions, five have never been recorded in South Africa before, highlighting our poor understanding of aquatic insect distributions in this part of the world.

Most of the species collected (almost 80%) belonged to the family Dytiscidae, more commonly known as “diving beetles” due to their lifestyle that involves coming up for air and immediately diving back down to the depths to carry on hunting unsuspecting prey, which can be as large as small fish and amphibians.

Prof Perissinotto and his NMMU colleague Dr Matthew Bird, together with water beetle specialist Prof David Bilton (Plymouth University), collected specimens ranging from 1 mm to almost 5 cm in length (the tadpole eaters). According to Prof Bilton, “Irrespective of size, these water beetles are a crucial component of the iSimangaliso ecosystem in that they are the primary predators in these temporary wetlands, which generally lack fish. Their abundance and diversity can be used to gauge the overall health of wetland ecosystems as they are sensitive to pollution, for instance”.

Singing in the rain: A new species of rain frog from Manu National Park, Amazonian Peru

A new rain frog species has been described from Amazonian Peru and the Amazonian foothills of the Andes. The frog, given the name Pristimantis pluvialis, was found by researchers from Southern Illinois University Carbondale, the University of Michigan, and the National University of San Antonio Abad of Cusco in Peru. The discovery is published in the open access journal ZooKeys.

Several individuals of P. pluvialis were found during nocturnal surveys near Manu National Park, a region recognized as having the highest diversity of reptiles and amphibians of any protected area.

The species has also been collected within the private conservation area Bosque Nublado, owned by the Peruvian NGO Perú Verde, and within the Huachiperi Haramba Queros Conservation Concession, the first such type of concession granted to a native community in Peru.

The new species is likely found within the park as well, bringing the number of known amphibian species in this area to 156. Similarly to other species within its genus, which is among the largest vertebrate genera, the new rain frog exhibits direct development. This means that it is capable of undergoing its entire life cycle without a free-living tadpole stage.

It can be distinguished from other members of its genus by call, skin texture, and the presence of a rostral papilla. It was given the name “pluvialis”, translatable to “rainy” from Latin, to denote the incredibly rain-soaked habitat it lives in (>8 meters of rain yearly), and because it was found calling only after heavy rains.

Unfortunately, when a fungal disease, known as the amphibian chytrid fungus, arrived in the area back in the early 2000s, many frog species in and around the region began to decline. Out of the studied ten individuals of the presently described new species, four were found to be infected. However, the impact of the disease on these particular rain frogs is still unknown, and their numbers do not seem to have decreased.

“This discovery highlights the need for increased study throughout the tropics, for example Manu NP and its surrounding areas have been well studied, but despite these efforts, new species are being continuously discovered,” points out first author Alex Shepack, a PhD student in the laboratory of co-author Dr Alessandro Catenazzi at Southern Illinois University.

Finding the real treasure of the Incas: Two new frog species from an unexplored region

Inaccessibility and mysticism surrounding the mist-veiled mountains of the central Andes make this region promising to hide treasures. With an area of 2197 km2, most of the Llanganates National Park, Ecuador, is nearly unreachable and is traversed only by foot. However, fieldwork conducted by researchers from the Museo de Zoología at Catholic University of Ecuador resulted in the discovery of a more real and tangible gem: biodiversity.

Among other surprises, during their expeditions the researchers discovered two new species of rain frogs, formally named P. llanganati and P. yanezi. The new species are characterized by the spiny appearance typical of several species inhabiting montane forests. The study was published in the open access journal ZooKeys.

The new rain frogs belong to the megadiverse genus Pristimantis. They are direct-developing frogs, which means that they lack a tadpole stage and therefore do not undergo metamorphosis.

The Neotropical Andes houses a spectacular radiation of Pristimantis, especially in the Montane Forests of the eastern slopes of the Ecuadorian Andes. The species richness of this genus is still underestimated as a consequence of their cryptic morphology and the still sparse amphibian inventories in unexplored regions such as the Llanganates National Park.

The discovery reminds the authors of a mystic local legend dating from the 16th century, when the Inca Empire fell into the hands of Spanish conquerors. Word has it that in exchange for the young emperor’s life, Atahualpa, Incas offered to fill an entire room with tons of gold. However, the Spaniards broke their promise and the emperor was executed. A small group of loyal Incas led by General Rumiñahui decided to hide both, the mummy of Atahualpa and the gold, in the depths of the jungle of the Llanganates National Park.

One of 8 new endemic polyester bees from Chile bears the name of a draconic Pokemon

Among the eight new bee species that Spencer K. Monckton has discovered as part of his Biology Master’s degree at York University, there is one named after a popular draconic creature from the Japanese franchise Pokémon. Called the stem-nesting Charizard, the new insect belongs to a subgenus, whose 17 species are apparently endemic to Chile, yet occupy a huge variety of habitats.

The young scientist, who is currently a PhD student at the University of Guelph, studying sawfly systematics and phylogeography, has his work published in the open access journal ZooKeys.

Known as polyester bees, the family to which the new species belong is characterized by the curious secretions these bees produce. Once applied to the walls of their nest cells, the secretion dries into a smooth, cellophane-like lining.

The new bee species are endemic to Chile, yet they occupy a huge variety of habitats ranging from the hyper-arid Atacama Desert in the north, to moist forests of monkey puzzle trees in the south, spanning elevations from the Pacific coast to more than 3200 metres above sea level. All of them are also solitary and nest in hollow plant stems.

Although the new bee species might lack the fiery breath of the dragon-like Pokémon, much like its namesake, it is normally found around mountains. Also, like the fictional species, the new bee has a distinctively long, snout-like face and broad hind legs, with antennae in place of horns.

However, the stem-nesting Charizard bee, as well as the other new species, are tiny creatures that measure between 4 and 7 mm in length. Unlike the predominantly orange colouration of the Pokémon, both males and females are mostly dark brown to black, patterned with variable yellow markings.

Yet, sometimes these yellow markings can turn orange when specimens are preserved, as was the case for the first specimen that Spencer Monckton observed of this species, which, he says, “cemented the comparison”.

In his research paper Spencer Monckton not only describes eight new endemic polyester bees, but he also provides thoroughly illustrated keys for identification of both the males and females of each of the species.

The first long-horned beetle giving birth to live young discovered in Borneo

A remarkably high diversity of the wingless long-horned beetles in the mountains of northern Borneo is reported by three Czech researchers from the Palacký University, Olomouc, Czech Republic. Apart from the genera and species new to science, the entomologists report the first case of reproduction by live birth in this rarely collected group of beetles. The study was published in the open access journal ZooKeys.

Generally, insects are oviparous, which means that their females lay eggs and the embryonic development occurs outside the female’s body. On the other hand, ovoviviparous species retain their eggs in their genital tracts until the larvae are ready to hatch. Such mode of reproduction is a relatively rare phenomenon in insects and even rarer within beetles, where it has been reported for a few unrelated families only.

The long-horned beetles are a family, called Cerambycidae, comprising about 35,000 known species and forming one of the largest beetle groups.

“We studied the diversity of the rarely collected wingless long-horned beetles from Borneo, which is one of the major biodiversity hotspots in the world,” says main author and PhD student Radim Gabriš. “The mountains of northern Borneo, in particular, host a large number of endemic organisms.”

The scientists focused on the group which nobody had studied in detail for more than 60 years. They found surprisingly high morphological diversity in this lineage, which resulted in the descriptions of three genera and four species new to science.

“During a dissection of female genitalia in specimens belonging to the one of the newly described genera, named Borneostyrax, we found out that two females contained large larvae inside their bodies,” recalls Radim Gabriš. “This phenomenon have been known in a few lineages of the related leaf beetles, but this is the first case for the long-horned beetles.”

However, according to the authors, the modes of reproduction remain unknown for many beetle lineages besides Cerambycidae, so the ovoviviparity might be, in fact, much more common. Further detailed studies are needed for better understanding of the reproductive strategy in this group.

Hollywood star Brad Pitt shares a name with a new wasp species from South Africa

Not only did an international research team discover two new endoparasitic wasp species in South Africa and India, and significantly expanded their genera’s distributional range, but they also gave a celebrity name to a special one of them.

While thinking of a name for the new wasp, Dr Buntika A. Butcher, Chulalongkorn University, Thailand, recalled her long hours of studying in her laboratory right under the poster of her favourite film actor. This is how a parasitic wasp from South Africa was named after Hollywood star Brad Pitt. The researchers have published their findings in the open access journal ZooKeys.

The new wasp species, called Conobregma bradpitti, belongs to a large worldwide group of wasps parasitising in moth or butterfly caterpillars. These wasps lay their eggs into a host, which once parasitised starts hardening. Thus, the wasp cocoon can safely develop and later emerge from the ‘mummified’ larva. Despite their macabre behaviour, many of these wasp species are considered valuable in agriculture because of their potential as biological control.

Brad Pitt’s flying namesake is a tiny creature measuring less than 2 mm. Its body is deep brown, nearly black in colour, while its head, antennae and legs are brown-yellow. The wings stand out with their much brighter shades.

Interestingly, the wasp with celebrity name unites two, until now, doubtful genera. Being very similar, they had already been noted to have only four diagnostic features that set them apart. However, C. bradpitti shared two of those with each. Thus, the species prompted the solution of the taxonomic problem and, as a result, the two were synonymised.

In their paper, the authors from Chulalongkorn University, Thailand and the University of Calicut, India, also describe another new species of parasitic wasp. It is the first from its subtribe spotted in the whole of India, while its closest ‘relative’ lives in Nepal.
