They say beauty is everywhere if we have eyes to see; a team of scientists looked at a tiny, 3-mm snail and saw art.
An international group of malacologists (researchers studying molluscs) led by Serbian PhD student Vukašin Gojšina and his Hungarian supervisor, Barna Páll-Gergely, was exploring snail diversity in Southeast Asia when a species unknown to science grabbed their attention, prompting them to name it after cubist artist Pablo Picasso.
Unlike most other snails, Anauchen picasso has rectangularly angled whorls that, according to the scientists, make it look “like a cubist interpretation of other snails with ‘normal’ shell shapes.”

The research team just published a 300-page article including the descriptions of 46 new species of microsnails from Cambodia, Myanmar, Laos, Thailand, and Vietnam.

“Although the shell sizes of these snails are less than 5 mm, they are real beauties! Their shells exhibit extraordinarily complexity,” they say. “For example, the aperture (the ‘opening’ of the shell) is armed with numerous tooth-like barriers, which are most probably useful against predators. Furthermore, several of the new species have an aperture that turns upwards or downwards, which means that some species carry their shells upside-down.”
These apertural barriers and the orientation of the last whorl on the shell were among the primary characters that helped the researchers tell different snails apart.

While many of these new species were collected recently, several, unknown to science until now, were found in the collection of the Florida Museum of Natural History, collected all the way in the 1980’s. It is likely (and in some cases, certain) that the locations where these snails were found have already been destroyed by deforestation and limestone quarrying, which are the major threats to locally endemic land snails in Southeast Asia.

In the heart of Canada’s Rocky Mountains, an unassuming yet remarkable butterfly has been quietly flying under our scientific radar for years. With a wingspan of an inch to an inch and a half, and wings that are brown on top and greyish brown with black spots below, this population was long thought to belong to the Half-moon Hairstreak (Satyrium semiluna). However, the isolated hairstreak butterflies of Blakiston Fan in Waterton Lakes National Park, Alberta, have now been recognized as a distinct species: Satyrium curiosolus, or the Curiously Isolated Hairstreak.
Satyrium curiosolus.
A recent study by an international collaborative team, published in ZooKeys, uncovered the unique evolutionary history of this population. The results were striking: Satyrium curiosolus has been completely isolated from its closest relatives for quite a while—possibly up to 40,000 years— becoming more and more genetically and ecologically unique along the way.
The science behind the discovery
“Our whole-genome sequencing of S. curiosolus revealed strikingly low genetic diversity and exceptionally high levels of historical inbreeding compared to the geographically nearest S. semiluna populations in British Columbia and Montana, more than 400 km distant,” says co-first author Zac MacDonald, a La Kretz postdoctoral researcher at University of California Los Angeles Institute of the Environment and Sustainability. Despite its small population size, genetic data suggest that S. curiosolus has likely maintained itself as a stable, independent lineage for tens of thousands of years. “Like the Channel Island Fox, S. curiosolus may have purged some of its harmful recessive genetic variation through a long, gradual history of inbreeding, allowing it to persist as a small and completely isolated population today,” MacDonald adds.

Satyrium curiosolus is found in a distinct habitat unlike any other population of S. semiluna that we know of. While its relatives thrive in sagebrush steppe, S. curiosolus occupies a single alluvial fan that is more accurately described as prairie-grassland, where it associates with different plants and ant species. Satyriumcuriosolus relies exclusively on silvery lupine (Lupinus argenteus) for larval development, a plant not known to be used by S. semiluna populations in British Columbia.

“Furthermore, we recently discovered that S. curiosolus larvae have mutualistic relationships with a particular species of ant (Lasius ponderosae), which has not been observed in other S. semiluna populations,” says James Glasier of the Wilder Institute/Calgary Zoo, who was also part of the study. Satyrium curiosolus caterpillars provide the Lasius ants with a sugary excretion called honeydew to eat, while in return the ants protect the caterpillar from parasites and predators. Caterpillars also retreat into ant galleries when disturbed, or when it gets too hot out, and adult females have been observed laying eggs right near the entrances to Lasius colonies under Silvery Lupines.
Why it matters
The recognition of S. curiosolus as a species has important implications, highlighting its unique evolutionary trajectory and emphasizing an urgent need for tailored conservation strategies.
The discovery of S. curiosolus is a powerful demonstration of how genomics is revolutionizing taxonomy and conservation.

Satyriumcuriosolus faces a somewhat unique challenge: its long-term isolation has resulted in very low genetic diversity, which means that the species has a reduced potential to adapt to changing climatic conditions. While conservationists often consider genetic rescue—introducing individuals from related populations to boost genetic diversity—as a solution to low genetic diversity, the distinctiveness of S. curiosolus raises concerns about potential outbreeding depression when mixed with S. semiluna. It is likely that the two species are not even reproductively compatible, meaning S. curiosolus may be on its own. Conservation efforts must now consider new solutions, such as establishing additional S. curiosolus populations, to help this butterfly persist as climate change threatens ecological change at Blakiston Fan.
A case study in genomics and conservation

“The discovery of S. curiosolus is a powerful demonstration of how genomics is revolutionizing taxonomy and conservation,” remarked co-first author Julian Dupuis, an Assistant Professor in the Department of Entomology at University of Kentucky. “While traditional taxonomic methods often rely on morphology alone, our study underscores the importance of integrating genomic and ecological data to uncover hidden diversity. With the rise of genomic tools, previously unrecognized species like S. curiosolus are being discovered, highlighting the need for conservation strategies that account for cryptic biodiversity.” Dupuis adds.
Collaboration in conservation
The Curiously Isolated Hairstreak reminds us that even the smallest and most overlooked species can hold extraordinary scientific and conservation significance.
“Our studies on S. curiosolus and S. semiluna highlight the importance of collaboration between academic scientists, nonprofit organizations, and conservation managers. All of this work was made possible through partnerships between academic researchers, Parks Canada, and the Wilder Institute/Calgary Zoo. By combining expertise in genomics, field ecology, and conservation management, we were able to produce findings that not only reshape our understanding of biodiversity but also provide actionable insights for species protection. Moving forward, these interdisciplinary collaborations will be critical for tackling complex conservation challenges and ensuring the long-term survival of species like S. curiosolus,” added MacDonald.
The future of Satyrium curiosolus
Title: S. curiosolus larvae being attended to by Lasius ponderosae ants.
Recognizing S. curiosolus as a distinct species is just the beginning, the researchers say. Future research should explore its evolution and interactions with other species like host plants and ants. Additionally, long-term monitoring by Parks Canada and the Wilder Institute/Calgary Zoo will be essential to assess how this species copes with climate change and what conservation actions are appropriate. “This is a wonderful example of how such monitoring can connect diverse approaches and impactful answers to a simple question like ‘that’s odd – why is it there?’”, says anchor author Felix Sperling, a professor at the University of Alberta and curator of the U of A’s Strickland Museum of Entomology.
“For now, the Curiously Isolated Hairstreak reminds us that even the smallest and most overlooked species can hold extraordinary scientific and conservation significance,” the researchers say in conclusion.

The initiative aims to make it easier to access and use biodiversity data associated with published research, aligning with principles of Findable, Accessible, Interoperable, and Reusable (FAIR) data.
The data portals offer seamless integration of published articles and associated data elements with GBIF-mediated records. Now, researchers, educators, and conservation practitioners can discover and use the extensive species occurrence and other data associated with the papers published in each journal.
A video displaying an interactive map with occurrence data on the BDJ portal.
The collaboration between Pensoft and GBIF was recently piloted with the Biodiversity Data Journal (BDJ). Today, the BDJ hosted portal provides seamless access and exploration for nearly 300,000 occurrences of biological organisms from all over the world that have been extracted from the journal’s all-time publications. In addition, the portal provides direct access to more than 800 datasets published alongside papers in BDJ, as well as to almost 1,000 citations of the journal articles associated with those publications.
“The release of the BDJ portal and subsequent ones planned for other Pensoft journals should inspire other publishers to follow suit in advancing a more interconnected, open and accessible ecosystem for biodiversity research,” said Dr. Vince Smith, Editor-in-Chief of BDJ and head of digital, data and informatics at the Natural History Museum, London.

“The programme will provide a scalable solution for more than thirty of the journals we publish thanks to our partnership with Plazi, and will foster greater connectivity between scientific research and the evidence that supports it,” said Prof. Lyubomir Penev, founder and chief executive officer of Pensoft.
On the new portals, users can search data, refining their queries based on various criteria such as taxonomic classification, and conservation status. They also have access to statistical information about the hosted data.
Together, the hosted portals provide data on almost 325,000 occurrence records, as well as over 1,000 datasets published across the journals.
A team from the Leibniz Institute for the Analysis of Biodiversity Change (LIB) has discovered groundbreaking ways for rapidly digitizing collection data. Data of insect specimen labels can now be easily read with just a smartphone – and all wirelessly and using only free, already available apps!
Screenshots from a mobile phone showing the steps of scanning of real-time data collection, and examples of labels: A step 1: marking of the text to be captured via touch screen of the mobile phone (example – printed labels scanned on pin) B step 2: select from menu bar (at the right side under three dots) “Copy to computer” (example – printed labels scanned separately). C Capture of multidirectional printed labels scanned separately from the specimen in “Google Lens” D Capture of multiple distorted, printed labels scanned on the pinned specimen in “Google Lens” E Initial capture of a printed label scanned separately from the specimen in “Google Keep” F Extracted data resulting from E.
Why is this important?
Around 1.1 billion objects in the largest natural history museums worldwide remain undigitized and manual extraction of specimen label information for taxonomic revisions, another source for biodiversity data mobilization, is very time consuming. By digitizing these data, we can preserve valuable knowledge about our biodiversity, especially in times of climate change and human biodiversity crisis when many species are going extinct before they are even discovered.
This innovation will accelerate and advance global research and the preservation of our biological knowledge. And the best part? It’s not expensive and accessible to everyone – from professionals to amateur scientists!

Importance of the study
“This discovery not only expands our understanding of cloud forest biodiversity but also highlights the urgent need to conserve these ecosystems in the face of growing environmental threats,” said Andrea Varela, lead researcher of the study.

The paper also examines the impact of the Andes on the diversification of this group. Colonization events across the Andes have been very rare; in the studied group, only two such events were recorded, over 14 million years ago, both from the Amazon towards the Pacific basin. These findings underscore the crucial role of the Andean barrier in the evolution and distribution of these species, offering a unique perspective on the complex biogeographic history of the Andes—one of the most biodiverse ecosystems on Earth.

“We have not only revived Francis Walker’s species Topiris candidella, from 1863, but also expanded our understanding of an entire group of small white moths.”
A moth neglected by experts for a century is found to have been collected by Alfred Russel Wallace 169 years ago
Cutting-edge techniques allowed scientists to show the moth as belonging to a genus comprising 14 species, 11 of which are new to science
One of the new species has been named after Greta Thunberg
Alfred Russel Wallace
Scientists at the Natural History Museum (NHM), London, have discovered that a long-overlooked moth specimen in the Museum’s collection was in fact collected by explorer and naturalist, Alfred Russel Wallace, in 1855. This was at the same time as he was formulating his own revolutionary ideas on the origins of species which he would go on to share with Charles Darwin.
The small white moth, Topiris candidella, was described in 1863 by Francis Walker but was dismissed in 1927 by leading entomologist Edward Meyrick as “better neglected” having suffered substantial damage due to historic storing practices. The moth has remained overlooked for nearly a century, until now.
Using a cutting-edge DNA sequencing method, NHM scientists extracted genetic material from a single fragment of one of the specimen’s remaining legs and connected it to a group of moths found throughout South East Asia.
The scientists were able to prove that rather than being a single neglected species, Topiris is in fact a genus of 14 species, including 11 species which are new to science and described today in the paper published in ZooKeys.
One of these species is named Topiris thunbergella, in honour of Greta Thunberg and her work in raising awareness of the environmental pressures on the native forests of South East Asia.

Dr David Lees, Senior Curator for Microlepidoptera at the Natural History Museum, adds, “This discovery highlights the incredible potential of modern DNA analysis to reveal the evolutionary history of species, even from fragmented and long-forgotten specimens.
“By applying this innovative sequencing technique, we have not only revived Francis Walker’s species Topiris candidella, from 1863, but also expanded our understanding of an entire group of small white moths.”
During their research, David and fellow moth expert, Mark Sterling, found that a hidden label under the pin of the broken moth bore the handwritten letters “SAR”, a clue that this moth had been collected by Alfred Russel Wallace as part of over a thousand moths he collected at Rajah Brooke’s Forest retreat.

This was in December 1855, just months before he published his ‘Sarawak Law’ paper, which eventually led to a joint reading (at Darwin’s request) of their theories of evolution through natural selection.
Beyond the scientific breakthrough, the study has wider conservation implications. Of the 24 species reviewed in their paper, only three have been recorded since 2000, highlighting the urgent need for biodiversity monitoring in this region.
Mark Sterling added, “The 80 million specimens currently held in the Natural History Museum’s collections continue to be a critical resource for understanding biodiversity and assessing the effects of environmental change.”

Recognizing the Sundaic rhinoceros as a separate genus not only improves scientific understanding but also has important implications for conservation efforts.
A new study revealed significant differences in the appearance and behaviour of the two one-horned Asiatic rhinoceros species, challenging long-standing classifications and supporting a re-evaluation of their status.

The study, led by zoologist Francesco Nardelli and paleontologist Kurt Heißig, highlights how millions of years of evolutionary pressures have shaped the distinct adaptations of the Indian (Rhinoceros unicornis) and Sundaic (Rhinoceros sondaicus)rhinoceroses. The critically endangered Sundaic rhinoceros has a slender skull, a broader and lower back of the head, and a shorter nose and teeth suited for browsing leaves. In contrast, the Indian rhinoceros has a more robust skull and taller teeth adapted for grazing on grasses.
“Adaptations of large terrestrial mammals to various environments are linked to the diversity of food items they can consume, which is reflected in the variation of their dental and cranial morphologies,” the researchers write in their paper, published in the journal ZooKeys. “In rhinoceroses, these adaptations are identified in their teeth structure and head posture.”
The Sundaic rhinoceros, now confined to Java’s Ujung Kulon peninsula, is a browsing species with uniquely polygonal-patterned skin and, unlike any other living rhinoceros, hornless females. In contrast, the Indian rhinoceros is a grazer of riverine grasslands in northern India and Nepal. With deep skin folds and a heavier build, the Indian rhinoceros is considerably larger than its Sundaic relative. It is superseded in size only by the elephant and the white rhinoceros, with males weighing more than 2,000 kg and females reaching 1,600 kg.

Fossil evidence confirms that these differences evolved independently over a long period of time. The authors maintain that they represent fundamental anatomical and ecological distinctions and reflect deep evolutionary adaptations.
The behaviour of the two species also differs significantly, with the Sundaic rhinoceros being solitary wanderers and Indian rhinoceros forming temporary crashes.
“Both species possess unique adaptations for survival, emphasising the importance of understanding their systematics for effective conservation,” the researchers write in their paper.
Based on these findings, the scientists propose a more precise scientific name for the Sundaic rhino: Eurhinoceros sondaicus. “Recognizing Eurhinoceros sondaicus as a distinct genus provides a more accurate reflection of its evolutionary history and ecological specialization,” they assert. “This refined classification not only enhances our understanding of rhinoceros evolution but also provides a clearer framework for conservation planning, helping to tailor strategies for the protection of these critically endangered animals.”

The frog Alsodes vittatus is an elusive creature – described in 1902, it managed to go undetected for more than a century. Now, after a decade of investigation, a research team has rediscovered it, in its first sighting after 130 years.
A female individual of Alsodes vittatus.
Researchers from the Laboratory of Systematics and Conservation of Herpetozoa (SyCoH) of the University of Concepción, Chile – Dr. Claudio Correa, engineer in renewable natural resources Edvin Riveros Riffo, and biologist Juan Pablo Donoso, have published their extraordinary discovery in the journal ZooKeys.
Alsodes vittatus was scientifically described in 1902 by Rodulfo Amando Philippi, a German naturalist living in Chile. French entomologist Philibert Germain had discovered the species in 1893 at the former Hacienda San Ignacio de Pemehue in La Araucanía Region, Chile, and brought three specimens to Philippi for description. Since then, no one has seen the species again, despite multiple search efforts.

Between 1995 and 2002, several researchers unsuccessfully tried to find it in the Pemehue area, at the northwestern end of the former estate. In 2015 and 2016, new expeditions led by Claudio Correa and Juan Pablo Donoso managed to locate two populations of Alsodes in the same area, but the individuals they saw lacked A. vittatus’ distinctive white or yellow stripe on the back, suggesting they likely belonged to a different species.

“The main challenge in locating it was the lack of precision in the description of its type locality,” say the researchers. “In Germain’s time, the Hacienda San Ignacio de Pemehue was an estate of enormous size, and the naturalist did not specify the exact place where he collected the specimens.”
To locate the species, Correa and his team had to reconstruct the route that Germain could have followed within the estate by studying his publications and other historical documents. In 2023 and 2024, Claudio Correa and Edvin Riveros followed the reconstructed route, entering the former estate from the southeastern end. There, they found two populations of A. vittatus in the Lolco and Portales river basins in La Araucanía region, confirming the existence of this enigmatic species after more than a century without records.

This is an important milestone for South American herpetology and the conservation of biodiversity in the southern cone. Most of the other species in the genus Alsodes are either threatened with extinction or we don’t know enough about them to assess their status, and shedding light on where and how they live is the first step in protecting them.
“The rediscovery of A. vittatus allowed us to obtain, more than a century after its description, the first biological and ecological data on the species. Field observations also indicate that this amphibian faces several significant threats and that it could be considered endangered,” the researchers warn. “In a broader context, this rediscovery demonstrates the limited biological, evolutionary and biogeographic knowledge of the amphibians that inhabit the southern cone of South America, emphasizing the urgency of their study and conservation.”

When Rebecca Tarvin was a graduate student studying toxins in the skins of poisonous frogs, she and her colleague Mileidy Betancourth-Cundar collected a frog in Colombia that they suspected was a new species. It differed in coloration from a similar Colombian frog in the genus Epipedobates and had a different mating call.

In 2022, eight years later and a newly appointed assistant professor of integrative biology at the University of California, Berkeley, Tarvin met up with Colombian biologists to collect more of these frogs and confirm a new species. Such “holotype specimens” are necessary to document a new species for posterity. Collecting specimens and identifying new species also helps scientists track the impact of environmental changes and understand the evolutionary origin of traits such as skin toxins, which may one day have medical uses.

Collecting the frogs was easy; they seem to thrive along roadsides and in semiurban areas. But what to name the species? A Colombian colleague played for the team a tape of local marimba-based music called bambuco, and one style, called bambuco viejo, or currulao, stood out. The name Epipedobates currulao seemed appropriate, and with this month’s publication of a paper describing the new species in the journal ZooKeys, it’s now official.

“We ended up going with currulao because we liked how it brought in the human perspective,” Tarvin said. “The frog is part of the sound landscape; when they call, it’s part of the background noise in the region. Similarly, currulao is more than just a genre of music. It’s also the cultural practices around the music, the gathering, dancing and the relationship-forming aspects of the experience.”

Tarvin is still investigating the toxins produced by frogs in the genus Epipedobates, which is small, containing about eight species, but is the most recently evolved group of poisonous frogs in South America. By comparing the genetics of these frogs with other poison frog groups, she hopes to understand how their chemical defense technique evolved. Most poisonous animals are brightly colored to advertise their unpalatability, such as the Monarch butterfly’s bright orange color and the gaudy orange, black and blue of poison dart frogs. But Epipedobates frogs are more subtly colored, if not downright drab. Perhaps, she said, bright coloration evolves after the frogs develop their toxic defenses.

Epipedobates acquired its chemical defenses more recently than any other group in the poison frog family and shows the largest range in color and defense, Tavin said, but they’re also interesting because of how they acquire their toxicity.
“What’s unique about poison frogs, specifically, is that they sequester toxins from their food, so it’s an entirely different kind of defense that requires an entirely different physiology, compared to venom-producing animals, like snakes and bees,” she said. “Poison frogs eat arthropods that have small amounts of chemicals that can be either toxic or distasteful. And then they accumulate those to levels that become relevant for their own predators.”
Tarvin offers one piece of advice: Because they’re covered in poisons, don’t lick your fingers after picking one up.

More than 99.9% of global species diversity is found within soils, according to a new review paper published in ZooKeys.
Comparing different studies on soil biota, author Robert J. Blakemore challenges previous estimates, which suggested a much lower proportion of life in soils. “Most life is found in Soil and most is microbial, affected by the current mass extinction event having profound effects influencing all evolution on Earth,” he says.
From the review paper: “Micro monde” progressions with microbial proportions greatly increased from Blakemore after Larsen et al.
“Soil filters and stores freshwater stocks (being subject to Earth tides!) and, as well as ~ 99% of human food, it provides most building materials plus many of our essential medicines/antibiotics. Thus, an important metric must be the scope and snapshot status of living or dormant Soil biota.”
One of the most recent estimates suggests that the soil realm is home to approximately 2.1 x 1024 taxa, which is thought to be more than 99.9% of global species biodiversity, mainly comprised of bacteria and other microbes.
The more you look, the more you find (lhs, pin-head after SCIENCE 2002; rhs, Bacteria on a pin tip courtesy Dr Kateryna Kon of Kharkiv National Medical University).
“Soil also supplies >99.7% of calorific food (just 0.3% from ocean plus 0.3% from aquaculture mostly fed with farmed stockfeed); with just about 6% total global protein from all fish; soil filters and stores most freshwater and is thus responsible for hydrological-recycle rainfall on land,” Blakemore says.
“My other paper last year on Biomass shows Soil houses >99% of organic carbon and it is the loss of this vital resources that is the greatest contributor to atmospheric carbon increase, despite the ‘greening’ effect on land.”
However, this immense biodiversity is under threat. “Soil erosion is one of our greatest global issues of concern, and one of the most ignored. Droughts, floods, deserts, poisoning, capping and so on are affecting all soils and, due to this massive soil loss, plants are incapable of thriving. At the same time deforestation continues, mainly clearing for cattle pastures or soy fields to feed CAFO cows (or other stock),” the author says.
The loss of soil biodiversity has far-reaching consequences, leading to ecosystem degradation, reduced food production, and loss of potentially valuable resources, such as sources of medicines and antibiotics. Furthermore, soil loss inevitably results in silent species loss, mostly of microbes that are most dominant in soils, but also of more obvious soil macrobes, and specifically of earthworms, which are vital for soil health.
Around 7,000 ‘true’ earthworm species have been described, but estimates suggest the total number of earthworm species may be closer to 30,000-35,000 globally. “Due to their high endemicity and Soil’s heterogeneity, their unknowns are legion,” the author notes in his paper.
From the review paper: Global Soil Biodiversity Atlas (GBIF 2016) reporting ~ 667,000 soil biota or just about one third of known 2 million). Note that earthworms have 7,000 known and > 30,000 estimated species. Bacteria had 15,000 known species but estimated over one million (< 1.5% described). However, when microbes (excluding viruses) are properly considered and counted, as herein, soil unknowns are much higher (likely just < 0.0001% known at best). Vascular plants add ~ 400,000 species (cf. Anthony et al. 2023 with 466,000 angiosperm “Plantae”).
Earthworms enhance microbial activity, improve soil structure, and promote plant growth, which is why Blakemore suggests that “a simple solution to soil degradation is to attempt, in any way and at all times, to preserve and enhance earthworm populations.”
“Healthy soils are carbon-rich, hugely biodiverse and are a massive sponge for water – neither flooding nor drying during climatic extremes,” the author says, a reminder that healthy soils are not only vital for maintaining biodiversity, but also indispensable in supporting essential functions of planet and human survival.
“Due to the most pressing problem of topsoil erosion and irreversible extinction losses, a major shift should be realizing the overwhelming importance and fragility of our precious Soil,” Robert Blakemore writes in his paper.
Calling for a change in attitudes and funding to recognise the true scope of soil biodiversity, he encourages the formation of a dedicated Soil Ecology Institute that would catalogue, research and reverse the mass degradation of our planet’s most crucial, yet most neglected ecosystem – that of the Soil Realm.
