New spider species discovered in Idaho, named in honour of the University of Idaho’s “Vandals”

Researchers at the University of Idaho have identified a new species of spider in the mountains of northern Idaho and given it a name that pays tribute to the university itself: Hexura vandal.

Researchers at the University of Idaho have identified a new species of spider in the mountains of northern Idaho and given it a name that pays tribute to the university itself: Hexura vandal.

The spider belongs to a small group of funnel-web spiders related to tarantulas. Until now, only two species in this genus were known, both living hundreds of miles away in the coastal forests and mountains of Oregon and Washington.

Finding a third species so far inland, in the Rocky Mountains near the town of Kooskia, came as a surprise to the research team, led by Arnau Calatayud-Mascarell, Ethan J. Briggs and Chris A. Hamilton. It extends the known range of the genus by roughly 500 kilometres and is the first new taxonomic work done on this group of spiders in almost fifty years.

Distribution and habitat of *Hexura* spiders including new records, records from iNaturalist, Gertsch and Platnick (1979), and The Burke Museum of Natural History in Seattle, Washington. Blue = H. picea, Pink = H. rothi, Yellow = H. vandal.

Associate Professor Dr. Chris A. Hamilton stated:

“It’s always exciting when you realize the samples you’ve been looking at are an undescribed new species. This is one of the main reasons we do this job – to document Earth’s incredible biodiversity and expand our foundational biological knowledge of our planet. It just makes it even more exciting when that undescribed diversity can be found in your backyard (figuratively speaking).”

The name is where the story becomes especially local. Rather than a Latin descriptor, the researchers chose “vandal”, which is a direct nod to the university’s own mascot. The nickname dates back to 1917, when student journalist Harry Lloyd McCarty described the men’s basketball team’s fierce style of play as “vandalizing” their opponents. The name stuck, and the University of Idaho remains the only Division I university in the United States with the Vandals as its mascot.

When discussing how the name was picked, Hamilton said:

“It didn’t take very long for the lab to sit down and decide what to name the new species. It was basically, this is really unique because it’s only found in Idaho and it’s not very far (relative) from campus. It’s black (sorry that it’s not black and gold like the school colors!). It’s a predator that attacks. It’s a Vandal.”

The discovery comes with a note of caution. Hexura vandal has so far only been found in a handful of sites within a very small area of forest in Idaho, despite repeated searches nearby. The region faces pressure from logging, and wildfires, which are becoming more frequent, and tend to strike during the spiders’ breeding season. Taken together, these factors have led the researchers to consider the micro-endemic species likely endangered, and they hope the discovery will help build the case for protecting its habitat.

The findings are described in a newly published scientific paper in ZooKeys by the research team, based at the University of Idaho’s Department of Entomology, Plant Pathology and Nematology.

University of Idaho, home of the Vandals, is Idaho’s land-grant university and the state’s first Carnegie R1 research institution — a ranking reserved for the top 4% of U.S. universities. From its residential campus in Moscow, U of I serves the state through centers in Boise, Coeur d’Alene, Idaho Falls and McCall, nine research and Extension centers, and Extension offices in 42 counties. With more than 12,000 students, U of I is a leader in student-centered experiential learning, interdisciplinary research, business and community service and global outreach. The Vandals compete as a founding member of the Big Sky Conference and as an affiliate in the Big West and Mountain Pacific Sports Federation.

The Pensoft Biodiversity Cup 2026 comes to a close

Now that the 2026 FIFA World Cup is over, it’s time for us to blow the final whistle on Pensoft’s Biodiversity Cup.

The floodlights have dimmed, the confetti has settled, and the 2026 FIFA World Cup has officially come to an end. A huge congratulations to Spain, who saw off Argentina 1-0 after extra time to lift their second World Cup trophy.

And with the football finished, it’s time for us to blow the final whistle on our own tournament too. Throughout the World Cup, we ran the Pensoft Biodiversity Cup alongside the real competition – a weekly knockout contest on our Instagram page, pitting some of the most remarkable species described in our journals against one another.

Every Thursday we opened the polls, and every Monday we brought you the result. Now that the dust has settled, we thought it was the perfect moment to look back at how the tournament unfolded.

Here’s how each fixture played out, with the winning species (as voted for by you!) shown in blue bold:

Date	Species #1	Species #2
11/06	Nadzikambia goodallae	Ferreiraella populi
18/06	Hellwigia opalina	Neohelicomyces coffeae
25/06	Thecacera sesama	Dolichopoda balrogi
02/07	Pikelinia floydmuraria	Trachischium lalremsangai
09/07	Theridion himalayana	Pyralis papaleonei
19/07	Iberoscia zaragozai	Echinodorus nenufar

General recap of Pensoft’s Biodiversity Cup.

Our first week’s competition kicked off with a cloud-forest chameleon named after Jane Goodall, which faced off against a public-named deep-sea chiton from the abyssal Pacific:

Pikelinia floydmuraria vs Trachischium lalremsangai.

The snake slithered through – Trachischium lalremsangai defeated Pikelinia floydmuraria, its burrowing lifestyle proving harder to top than a rock-star spider name in this round.

Our second-to-last round paired the smiley-faced Himalayan Happy-Face Spider, Theridion himalayana, against Pyralis papaleonei, a papal-named moth endemic to Crete’s White Mountains:

Theridion himalayana vs Pyralis papaleonei.

The moth flew past the competition! Pyralis papaleonei took the win over Theridion himalayana, its rare papal namesake and striking wing bands proving enough to edge out even a face full of smiles.

Our own final on 19 July ended up mirroring the World Cup final to a tee, with a species from Spain going head-to-head with one from Argentina:

View this post on Instagram

Iberoscia zaragozai vs Echinodorus nenufar.

Representing Spain in the final was Iberoscia zaragozai, a newly described genus and species of cave-dwelling isopod, published only this April in our open-access journal Subterranean Biology.

Discovered in caves across Catalonia, Murcia and the Valencian Community, this blind crustacean measures barely 3-4 mm long, yet required a new genus to accommodate it, thanks to its unique features – right down to its antennal sensory structures.

Fittingly, it’s named in posthumous tribute to the Spanish arachnologist Juan Antonio Zaragoza-Miralles, in recognition of his decades of work on the cave-dwelling fauna of the Iberian Peninsula.

Standing in Argentina’s corner was Echinodorus nenufar, a new aquatic plant described in PhytoKeys back in January. Found in the temporary ponds and seasonal wetlands of the dry Chaco region of northern Argentina and western Paraguay, it earns its name – “nenúfar” being Spanish for water lily – thanks to its rounded floating leaves and creamy-white flowers, which give it an uncanny resemblance to a true Nymphaeaceae water lily.

Like the seasonal killifish it shares its ephemeral ponds with, it has evolved to complete its whole life cycle in habitats that can appear and vanish with the rains.

Two species, two countries, both barely a few months old to science. This is a proper final if ever there was one. And… just like their footballing counterparts, it was the Spanish contender that came out on top!

We had an absolute blast running the Biodiversity Cup alongside this year’s World Cup, and we hope it gave you a fun new way to discover some of the incredible species being described in our journals. Thank you to everyone who voted, shared and cheered along from the side lines.

New snake species named in honor of Steve Irwin

The species is glossy black, reaches up to a meter in length, and is non-venomous. It is believed to be endemic to the island.

A new species of wolf snake was discovered from the Great Nicobar Islands, India.

Researchers R. S. Naveen and S. R. Chandramouli of the Pondicherry University, Zeeshan A. Mirza of the Max Planck Institute for Biology and Girish Choure of Pune published the discovery in the open-access journal Evolutionary Systematics.

The team named the new species Irwin’s wolf snake, or Lycodon irwini, after the late Stephen Robert Irwin, the renowned Australian zookeeper, conservationist, television personality, and wildlife educator. “His passion and dedication to wildlife education and conservation have inspired naturalists and conservationists worldwide, including the authors of the paper,” they write in their study.

The adults of the new species are glossy black and can grow to a meter in length. The snakes are non-venomous and likely feed on reptiles, amphibians and small mammals. Currently, the species appears to the endemic to the Great Nicobar Island in the Andaman and Nicobar Archipelago. Based on the narrow distribution range and potential human threats to the species, the authors suggest that it should be considered Endangered.

“New species continue to be discovered, exemplified by Lycodon irwini, highlighting the ongoing progress in taxonomy and the incomplete understanding of herpetofaunal diversity and distribution in the region,” the researchers write in their paper.

Hidden in sacred forests: A newly described microendemic gecko from Madagascar

Reserves managed by local communities are essential for the survival of species like P. tsaranoro.

A team of international herpetologists has described a new gecko species that has managed to hide in plain sight among the granite boulders around the western flanks of the Andringitra Massif, in south-eastern Madagascar. “Paragehyra tsaranoro is named after the Tsaranoro valley, where it was first observed,” explains first author Francesco Belluardo from the Department of Bioscience and Territory at the University of Molise (Italy). “It is not only endemic to Madagascar, but also what we describe as a microendemic species—restricted to an extremely small range.”

In this case, P. tsaranoro has only been found in three small forest fragments, all located within approximately 15 kilometers of one another. These patches are remnants of a once-larger and continuous forest that has been destroyed by the widespread deforestation that continues to impact Madagascar’s biodiversity.

“The findings emphasise the importance of conducting research on small forest fragments, as they are essential for completing the inventory of Malagasy herpetofauna,” the researchers write in their study, which was published in the journal ZooKeys.

Given its very limited range and the ongoing threats to its habitat, the authors recommend listing this new gecko as Critically Endangered on the IUCN Red List. Like many endemic species in Madagascar, its existence might be threatened by deforestation, which means destruction and fragmentation of its already limited habitat. The research team, composed also of Angelica Crottini, Javier Lobón-Rovira, Gonçalo M. Rosa, Franco Andreone, Malalatiana Rasoazanany, Costanza Piccoli and Ivo Oliveira Alves call for stronger support for local communities in conserving the species. In fact, most of its known range lies outside Madagascar’s network of protected areas, and the only conservation measures come from reserves managed by local communities—areas created to support sustainable livelihoods and protect local biodiversity.

“Building on previous research in the region, it appears that this landscape is full of hidden biodiversity gems, including other microendemic reptile species found nowhere else in the country. These community-managed reserves act as important refuges for local wildlife,” says Belluardo. “Interestingly, many of these small forest fragments are known locally as ‘Forêts sacrées’, or sacred forests, because they host boulders that serve as ancestral tombs for the local Betsileo people. Protecting this cultural heritage has also helped safeguard local species, suggesting once again that conserving biodiversity often goes hand-in-hand with preserving cultural traditions.”

Rare grasshopper thought extinct rediscovered after 40 years

Unique to the island of São Nicolau, the insect is a “living fossil” that has shown remarkable resilience, surviving for millions of years.

The Monte Gordo Grasshopper (Eyprepocprifas insularis) has proved to be a rare and elusive species: its last, and, until now, only sighting was a single specimen found in 1980. This is why researcher Dr. Michel Lecoq declared it extinct in 1996.

Scale bar: 1 cm. Photo credit: Christophe Herve, MNHN, Paris.

After more than 40 years of no records, an exciting discovery happened thanks to a holiday Rob Felix took with his fellow researcher Annelies Jacobs in Cape Verde, the insect’s only known location, “to look for birds and other interesting stuff for field biologists like us. Before going on our trip, we looked for information about this peculiar grasshopper that was thought to be extinct for a long time. We were hoping and dreaming that maybe we could find it again.”

“During a night walk on our first evening on São Nicolau to a colony of a unique seabird species, the Fea, I stumbled upon a grasshopper sitting on the path. When I looked closer in the torch’s light, I immediately recognised its unique appearance. I shouted out loud: it’s Eyprepocprifas! To my surprise, correct at once because it’s not the most easily pronounceable genus name,” he says.

In the following days, Rob and Annelies found several other specimens in Monte Gordo Natural Park and its surroundings.

Endemic to the island of São Nicolau, this grasshopper is a “living fossil,” meaning it hasn’t evolved significantly for millions of years and has few or no living relatives.

“E. insularis must have been there for a very long time and has been able to withstand the severe ecological conditions,” the researchers write in their paper, which was published in the Journal of Orthoptera Research.

This montane grasshopper has shown remarkable resilience, surviving in the challenging environment of Cape Verde’s islands and enduring periods of intense drought and strong winds that can introduce new species from the African continent.

“The rediscovery of the only endemic brachypterous (short-winged) grasshopper, Eyprepocprifas insularis, on São Nicolau, an island with a volcanic origin dating back approximately five million years, provides significant insight into the island’s ecological and evolutionary history,” the researchers write.

They say this rediscovery is a crucial first step toward the insect’s conservation: as a threatened species restricted to a small area, E. insularis might actually be closer to extinction than we think. Now that it has been found again, we have the opportunity to take steps to protect this unique species and its habitat.

Endangered and exceptional: Discovery of new insect species highlights Kosovo biodiversity hotspot

A remarkable discovery from Kosovo’s Bjeshkët e Nemuna National Park underscores the region’s high biodiversity and urgent need for conservation.

A new species of caddisfly, Tinodes lumbardhi, was found in a sidestream of the Lumbardhi i Deçanit River in Kosovo’s Bjeshkët e Nemuna National Park. The discovery, made by Professor Halil Ibrahimi of the University of Prishtina and his research team, underscores the region’s high biodiversity and urgent need for conservation.

*Tinodes lumbardhi*, the new species from Lumbardhi i Deçanit River in Kosovo

The aquatic insect is small, with its wings less than 5 mm long. Its name, “lumbardhi,” honors the local Albanian name for the river, meaning “the white river.”

“The discovery of Tinodes lumbardhi is both a celebration of Kosovo’s unique natural heritage and a wake-up call for conservation,” said Professor Halil Ibrahimi. “The survival of these species depends on our ability to protect their fragile habitats.”

The type locality of *Tinodes lumbardhi*, a shelter for several other rare species of caddisflies.

Hosting several rare and endemic species, Bjeshkët e Nemuna, a mountainous region in western Kosovo, is a hotspot for caddisfly diversity. Despite this richness, however, Kosovo’s freshwater ecosystems face escalating threats from human activities. Hydropower development, pollution, and water extraction have severely degraded habitats like the Lumbardhi i Deçanit River, leading in some areas to impoverished insect communities and an alarming absence of fish. Sidestreams like the one where T. lumbardhi was found serve as critical refuges for rare species but remain vulnerable to environmental pressures.

Caddisflies, known for their sensitivity to environmental changes, are key bioindicators of freshwater ecosystem health. These small insects are not only vital for biodiversity but also for maintaining ecological stability in the face of threats such as climate change and habitat destruction.

Heavy environmental pressures endanger the aquatic fauna of Lumbardhi i Deçanit River in Kosovo.

Kosovo’s caddisfly fauna has seen significant advancements in recent years, with contributions from Ibrahimi and his team shedding light on the region’s ecological treasures. Their work has revealed species such as Potamophylax kosovaensis and Potamophylax coronavirus, emphasizing the importance of ongoing research and conservation efforts.

The discovery of Tinodes lumbardhi adds to the growing recognition of Bjeshkët e Nemuna as a biodiversity hotspot of international significance. In their research paper, published in Biodiversity Data Journal, the researchers call for urgent targeted conservation measures to mitigate the impacts of hydropower development and other anthropogenic threats in the region. “Protecting these rare species and their habitats is not only a moral imperative but also a crucial step toward sustaining the ecological integrity of Kosovo’s freshwater systems,” says Halil Ibrahimi in conclusion.

Fourteen years after the Gulf of Mexico oil spill, endemic fishes face an uncertain future

A study investigating the spill’s impact on endemic fish species suggests potential loss of biodiversity.

The 2010 Gulf of Mexico Deepwater Horizon was the largest accidental oil spill in history. With almost 100 million gallons (379 million liters) of oil combined with dispersants suggested to remain in the Gulf, it is one of the worst pollution events ever. More than a decade later, its long-term effects are still not fully understood.

In a new study, researchers from Louisiana State University and Tulane University examined the endemic Gulf of Mexico fish species that may have been most impacted by the oil spill to see how their distribution has changed over the years. To get their data, they studied museum specimens from natural history collections, looked at relevant literature, and combed biodiversity databases.

With 1541 fish species known from the region, and 78 endemic fish species, the Gulf of Mexico is one of the most biologically rich and resilient marine environments in the world, but how much of this diversity is still left intact?

The study found that 29 out of the Gulf’s 78 endemic fish species haven’t been reported in museum collections since 2010. The Yucatan killifish, for example, which is considered endangered, was last reported pre-spill, in 2005, off the Yucatán Peninsula.

Six of the non-reported species are considered of greatest concern, because their areas of distribution largely overlap with the affected area – although the authors note that their absence in the Gulf in recent years cannot automatically be attributed to the oil spill.

“Understanding the impacts of catastrophic environmental events such as the 2010 Gulf of Mexico Oil Spill does not end when the wellhead is capped or when the last drops of oil cease to flow. The disaster only begins to end when the data no longer show impacts of the event. We are far from the beginning of the end for the Deepwater Horizon Oil Spill. Lingering chemicals, lost generations of wildlife and a continued ecosystem imbalance may all be factors that prevent an environment from rebounding from such cataclysmic events,” the authors note in their research article.

However, they also point out that nature’s ability to recover should not be overlooked.

“The Gulf of Mexico continues to face many challenges, from the Dead Zone, to climate change, loss of coast habitats and continued oil spills. Efforts like this report aim to bring attention to vulnerable species that continue to be impacted by human activities and to the unique endemic fauna of the region,” the researchers write in conclusion.

Five dazzling new species of eyelash vipers discovered in Colombia and Ecuador

The groundbreaking discovery was made official in a study published in the open-access journal Evolutionary Systematics.

A group of scientists led by researchers of Khamai Foundation discovered five dazzling new species of eyelash vipers in the jungles and cloud forests of Colombia and Ecuador. This groundbreaking discovery was made official in a study published in the open-access journal Evolutionary Systematics.

Prior to this research, the captivating new vipers, now recognized as among the most alluring ever found, were mistakenly classified as part of a single, highly variable species spanning from Mexico to northwestern Peru. The decade-long study initiated with an unexpected incident wherein one of the authors was bitten by one of these previously undiscovered species.

Distribution of the palm pitvipers of the *Bothriechis schlegelii* species complex, including the five new species described in Arteaga et al. 2014.

Eyelash vipers stand out due to a distinctive feature: a set of enlarged spine-like scales positioned atop their eyes. These “lashes” bestow upon the snakes a formidable and fierce appearance, yet the true purpose of this feature remains unknown. What is definite, however, is that certain populations exhibit longer, and more stylized eyelashes compared to others. The variations in the condition of the eyelashes led researchers to hypothesize the existence of undiscovered species.

The clue that led the researchers to suspect that there were new species of eyelash vipers was the fact that some populations in the cloud forests of Ecuador had almost no “lashes.” Photos by Lucas Bustamante and Jose Vieira.

Eyelash vipers are also famous for another feature: they are polychromatic. The same patch of rainforest may contain individuals of the turquoise morph, the moss morph, or the gold morph, all belonging to the same species despite having an entirely different attire. “No two individuals have the same coloration, even those belonging to the same litter (yes, they give birth to live young),” says Alejandro Arteaga, who led the study.

For some of the species, there is a “Christmas” morph, a ghost morph, and even a purple morph, with the different varieties sometimes coexisting and breeding with one another. The reason behind these incredible color variations is still unknown, but probably enables the vipers to occupy a wide range of ambush perches, from mossy branches to bright yellow heliconias.

Where do these new snakes live?

Three of the five new species are endemic to the eastern Cordillera of Colombia, where they occupy cloud forests and coffee plantations. One, the Rahim’s Eyelash-Pitviper, stands out for occurring in the remote and pristine Chocó rainforest at the border between Colombia and Ecuador, an area considered “complex to visit” due to the presence of drug cartels. The Hussain’s Eyelash-Pitviper occurs in the forests of southwestern Ecuador and extreme northwestern Peru. The researchers outline the importance of conservation and research in the Andes mountain range and its valleys due to its biogeographic importance and undiscovered megadiversity.

What’s with the venom?

“The venom of some (perhaps all?) of the new species of vipers is considerably less lethal and hemorrhagic than that of the typical Central American Eyelash-Viper,” says Lucas Bustamante, a co-author of the study. Lucas was bitten in the finger by the Rahim’s Eyelash-Pitviper while taking its pictures during a research expedition in 2013. “I experienced intermittent local pain, dizziness and swelling, but recovered shortly after receiving three doses of antivenom in less than two hours after the bite, with no scar left behind,” says Bustamante.

Researcher Alejandro Arteaga examines the fangs of Central American Eyelash-Pitviper (*Bothriechis nigroadspersus*) in the Darién jungle of Panamá.

How threatened are these new species?

One of the study’s key conclusions is that four of the species in the group are facing a high risk of extinction. They have an extremely limited geographic range and 50% to 80% of their habitat has already been destroyed. Therefore, a rapid-response action to save the remaining habitat is urgently needed.

Who is honored with this discovery?

Two of the new species of vipers, the Rahim’s Eyelash-Pitviper (Bothriechis rahimi) and the Hussain’s Eyelash-Pitviper (B. hussaini), are named in honor of Prince Hussain Aga Khan and Prince Rahim Aga Khan, respectively, in recognition of their support to protect endangered global biodiversity worldwide through Focused On Nature (FON) and the Aga Khan Development Network. The Shah’s Eyelash-Pitviper (B. rasikusumorum) honors the Shah family, whereas the Klebba’s Eyelash-Pitviper (B. klebbai) and the Khwarg’s Eyelash-Pitviper (B. khwargi) honor Casey Klebba and Dr. Juewon Khwarg, respectively, for supporting the discovery and conservation of new species.

What is next?

Khamai Foundation is setting up a reserve to protect a sixth new species that remained undescribed in the present study. “The need to protect eyelash vipers is critical, since unlike other snakes, they cannot survive without adequate canopy cover. Their beauty, though worthy of celebration, should also be protected and monitored carefully, as poachers are notorious for targeting charismatic arboreal vipers for the illegal pet trade of exotic wildlife,” warns Arteaga. Finally, he and his team encourage the support of research on the venom components of the new species of vipers. This will promote their conservation as well as help communities that regularly encounter eyelash pitvipers.

The most beautiful Vanilla: an unusual new species from Brazil’s Campos Rupestre

Brazilian Campos Rupestres have many endemic species, and a new study published in the journal PhytoKeys has just added one more.

One of the most beautiful vanilla orchid species in the Neotropical region grows in one of the most hostile environments in the Brazilian Cerrado, the Brazilian Campos Rupestres of the Espinhaço Range. “The Espinhaço refuges evolved between the Atlantic Forest and Amazonia Biomes as a consequence of extreme environmental conditions and climatic fluctuations during the Tertiary and Quaternary periods,” explains Emerson Ricardo Pansarin, one of the researchers behind the discovery of a new vanilla orchid.

What makes Vanilla rupicola remarkable is the fact that it grows on rock outcrops. “In this locality, Vanilla rupicola shows a reptant habit on rock outcrops and rooting in rock clefts. The elevation is from 800 to 1300 m a.s.l.,” the researchers write in their paper. Its flowers produce a sweet fragrance that can be noticed during the hottest hours of the day.

“For years we traveled through the mountains of the Espinhaço Range until we found the flowering population,” says Emerson Ricardo Pansarin.

“Vanilla rupicola emerges in an essentially Amazonian clade. It seems plausible that the ancestor of this new taxon derived from an Amazonian taxon adapted to the environmental conditions of the Espinhaço Range and evolved in this particular environment,” he adds.

Vanilla rupicola is a rare species currently known to grow in a mountain-chain of Diamantina, in the ERMG Espinhaço Range, and the researchers tentatively classify it as Endangered.

Pensoft’s science illustrator Denitsa Peneva wins first place at a prestigious international contest

“Dormice of Europe (Gliridae)” – an illustration combining watercolour and pencil – and Denitsa Peneva won at the Illustraciencia competition in the “Nature Illustration” category.

“Dormice of Europe (Gliridae)” – an illustration combining watercolour and pencil – and its author Denitsa Peneva won at the Illustraciencia competition in the “Nature Illustration” category. This year, the contest saw over 500 works.

Since 2009, the annual international event convened by the Spanish National Research Council and the Catalan Association of Scientific Communication has been recognising scientific illustrations with the aim to popularise science within the wider society.

Denitsa’s illustration depicts five dormouse species known from Europe: the Roach’s mouse-tailed or ground dormouse (Myomimus roachi), the forest dormouse (Dryomys nitedula), the European edible dormouse (Glis glis), the hazel dormouse (Muscardinus avellanarius) and the garden dormouse (Eliomys quercinus). Each of the rodents is seen on a plant that is typical either for its habitat or diet. Respectively, one of the species – which is a carnivore – is shown next to a snail.

Curiously, “Dormice of Europe (Gliridae)” was inspired by last year’s 11^th International Dormouse Conference, which took place in Svilengrad, Bulgaria. The locality was not chosen at random. It had just recently been found to house a large population of the rarest dormouse species for Europe. At the time, the Roach’s mouse-tailed or ground dormouse (Myomimus roachi), a species endemic to the Balkans, had not been encountered for almost 40 years.
