A newly identified wasp species, Chrysonotomyia susbelli, has been discovered in Houston, Texas, marking the 18th new species identified by Rice University’s Scott Egan and his research team since 2014. The discovery, the fourth wasp species found on the university grounds in seven years, reveals the hidden world of parasitoid wasps and the intricate ecosystems that thrive outside our doors.

Chrysonotomyia susbelli is a parasitoid wasp, about 1 millimeter long, that emerges from galls, or tumorlike growths created by the gall wasp Neuroterus bussae found on southern live oak leaves. The galls serve as microhabitats within which larvae feed, develop and pupate. The research team’s study was published in the journal ZooKeys on Sept. 18.

“Chrysonotomyia susbelli represents the sixth species of its genus described from North America and the first globally known to parasitize cynipid gall wasps,” said Egan, an associate professor of ecology and evolutionary biology.
The wasp was discovered and named by Brendan O’Loughlin, a Rice senior and the study’s first author. “The wasp’s goldenrod color is almost identical to the official colors of Wiess College, my residential college,” O’Loughlin said.
To confirm the uniqueness of the species, the research team conducted a genetic analysis and a detailed study of the wasp’s physical features under a microscope. Its investigation also included a review of the historical literature to ensure that the species had not been previously described.

This research was complemented by DNA barcode data and observations of the wasp’s natural history, including host associations and a unique leaf-scanning behavior exhibited by female wasps. The researchers also modified the identification key of New World members, groups of species found exclusively in the Americas, to incorporate this new species.
Egan emphasized the importance of studying local biodiversity. “You don’t have to travel to a distant rainforest to find new and beautiful things — you just have to step outside and look,” he said.
The discovery hints at a previously unexplored ecological niche involving Chrysonotomyia parasitoids, cynipid gall wasps, and oaks, suggesting that there may be many more undiscovered species within this system.
“Generations of Chrysonotomyia susbelli have likely lived unnoticed on the oaks of Rice University since its founding,” Egan said.
Co-authors of the study include Pedro FP Brandão-Dias, Ph.D. graduate of ecology and evolutionary biology at Rice and current postdoctoral scholar at the University of Washington, and Michael Gates, parasitoid wasp specialist of the U.S. Department of Agriculture’s Systematic Entomology Laboratory at the Smithsonian National Museum of Natural History.

Despite its small size of less than 2 centimeters, the grumpy dwarfgoby has a surprisingly menacing appearance. Its large canines and fierce expression give it a rather intimidating look for such a small fish.
Lucía Pombo-Ayora, who gave the species its grumpy common name, comments on its distinctive appearance: “I imagine in its own tiny world, it is a fearsome predator. Its grumpy expression and large canines certainly make it look the part, despite its small size.”
The species’ bright red coloration actually helps it blend into its natural habitat. It can be found on the walls and overhangs of coral reefs, covered in red coralline algae. There, it lives in small holes and crevices, using its large canines to capture tiny invertebrates. The grumpy dwarfgoby appears to be a relatively rare species, which is likely why it remained undiscovered until now.
The researchers found the first specimens in the Farasan Banks in Saudi Arabia, with additional specimens later found near Thuwal in the Red Sea. It was researcher Viktor Nunes Peinemann who first found it during a diving expedition to explore the coral reef fish diversity. Initially, the researchers thought they had rediscovered the fiery dwarfgoby, Sueviota pyrios, which is only known from a single specimen collected in 1972. However, upon closer examination, they realized they were dealing with an entirely new, undescribed species.
“The ongoing discovery of distinctive new species like this grumpy dwarfgoby shows how much biodiversity remains undiscovered in the Red Sea,” Viktor Nunes Peinemann explains. “This is concerning given the recent environmental changes in the region. In some cases, species could go extinct before we even describe them.”
The region is known for its high levels of endemic species and the Grumpy dwarf goby is another addition to this unique fauna. Much of the Red Sea has experienced major disturbances resulting from climate change in recent years, including widespread coral bleaching and mortality. The fact that new species are still being discovered in this rapidly changing environment highlights the urgency of continued research and conservation efforts, the researchers believe.
They have published their discovery in the open-access scientific journal ZooKeys.

A new species of tarantula spider, Aphonopelma jacobii, has been discovered from the Chiricahua Mountains in southeastern Arizona. This small, black and grey tarantula species has fiery red hairs on its abdomen and can be found in the high-elevation habitats of the Chiricahua Mountains, where it survives through bitterly cold winters.

The discovery was rather unexpected. “We often hear about new species being discovered from remote corners of Earth, but it is remarkable that these spiders are found in our own backyard, albeit in somewhat difficult-to-access areas of our backyard,” said Dr. Chris Hamilton, assistant professor at the University of Idaho and co-lead author of a study in ZooKeys that reports on the spider. “With Earth in the midst of a human-mediated extinction crisis, it is astonishing how little we know about our planet’s biodiversity, even for conspicuous and charismatic groups such as tarantulas.”

The Chiricahuas, renowned for their exceptional biodiversity and high levels of endemism, compose part of the Madrean Archipelago (colloquially referred to as the Madrean Sky Islands), a complex of forested mountain ranges that span the cordilleran gap between the Colorado Plateau and Rocky Mountains in the southwestern United States and the Sierra Madre Occidental in northwestern Mexico. These montane forest “islands”—separated from each other by low-elevation deserts and arid grasslands—have evolved in isolation, leading to the origin of numerous short-range endemic species, and resulting in a mosaic of biodiversity unlike that of any other region in the United States.

The forests where these tarantulas live are threatened by several factors, perhaps most notably from climate change. Recent studies in the sky island region suggest that these forests will be “pushed off” the mountains over the next several decades as temperatures and precipitation continue to increase and decrease, respectively. Organisms adapted to these cooler and more humid mountain tops—such as these spiders—will likely become extinct as suitable habitat disappears.
Dr. Brent Hendrixson, professor at Millsaps College and co-lead author of the study adds, “These fragile habitats are also threatened by increased exurban development in the San Simon Valley and Portal areas, destructive recreational activities, and wildfires. In addition, there is some concern that these tarantulas will be exploited for the exotic pet trade due to their rarity, striking coloration, and docile disposition. We must consider the impact that unethical collectors might have on these spiders when determining the threats to this species and the implications for its conservation.”

Aphonopelma jacobii is named after Michael A. Jacobi, who helped find several of the first specimens which led to the description of this new species.
“This discovery represents the 30th species of tarantula documented from the United States. Aphonopelma is the most species diverse tarantula genus on the planet (at least for documented species). Our research adds to this number and continues to advance our understanding of the true species diversity in this incredibly interesting and important biodiversity hotspot,”Dr. Hamilton says in conclusion.

Accelerating global change continues to threaten Earth’s vast biodiversity, including in the oceans, which remain largely unexplored. To date, only a small fraction of an estimated two million total living marine species have been named and described. A major challenge is the time it takes to scientifically describe and publish a new species, which is a crucial step in studying and protecting these species. The current scientific and publishing landscape often results in decade-long delays (20-40 years) from the discovery of a new species to its official description. As an alternative to this, the Ocean Species Discoveries initiative was launched, offering a new platform for rapid but thorough taxonomic description of marine invertebrate species.
One of the newly described species, Lepechinella naces.
The project coordinated 25 different researchers and produced data on thirteen marine invertebrate taxa, including one new genus, eleven new species, and one redescription and reinstatement. The species, which originate from all over the globe and at depths from 5.2 to 7081 meters, are brought together in an open-access publication in the Biodiversity Data Journal.
Only by leveraging the collective strengths of global progress, expertise, and technological advancements, will we be able to describe the estimated 1.8 million unknown species living in our oceans.

This is the first of a series of publications related to SOSA’s initiative, in collaboration with Biodiversity Data Journal, presenting a revolutionary approach in new species descriptions, thanks to which the publication of new species takes years, sometimes even decades, less. The ARPHA publishing platform, which powers the Biodiversity Data Journal, further expedites species descriptions and their use in studies and conservation programs by employing a streamlined data publishing workflow. ARPHA automatically exports all species data, complete with images and descriptions, to GBIF—the Global Biodiversity Information Facility and the Biodiversity Literature Repository at Zenodo, from where other researchers can easily find and use them.

One of the new species described in the Ocean Species Discoveries is Cunicolomaera grata, a curious amphipod whose burrows along the seafloor perplexed scientists. Another is a wrinkly-shelled limpet called Lepetodrilus marianae that lives on hydrothermal vents, underwater volcanoes in the deep-sea where temperatures can reach 400 degrees C. Normally, the descriptions for these two very different species wouldn’t be in the same publication, but this new publication format allows for species descriptions from different marine invertebrate taxa to be published together in one ‘mega-publication,’ offering a huge incentive for researchers to make their discoveries public.

“Currently, there’s a notable delay in naming and describing new animals, often because journals expect additional ecological or phylogenetic insights. This means many marine species go undescribed due to lack of data. OSD addresses this by offering concise, complete taxonomic descriptions without requiring a specific theme, refocusing attention on taxonomy’s importance,” says Dr. Torben Riehl, who is one of the researchers featured in Ocean Species Discoveries.

Reducing the time it takes to get from discovering a new animal to a public species description is crucial in our era of increasing biodiversity loss. The wrinkly-shelled limpet and two other species described in the Ocean Species Discoveries live in hydrothermal vent zones – an environment threatened by deep-sea mining. Another OSD species, Psychropotes buglossa, a purple sea cucumber (sometimes also called a gummy squirrel), lives in the North Atlantic, but similar species live in areas of high economic interest, where polymetallic-nodule extraction could soon endanger sea life. Threats like these risk driving species to extinction before we even get the chance to know and study them. Through efforts like SOSA’s Ocean Species Discoveries, we can get closer to understanding the biodiversity of our oceans and protecting it before it’s too late.

“Only by leveraging the collective strengths of global progress, expertise, and technological advancements, will we be able to describe the estimated 1.8 million unknown species living in our oceans. Every taxonomist specialized on some group of marine invertebrates is invited to contribute to the Ocean Species Discoveries,” says Prof. Dr. Julia Sigwart in conclusion.

Denver Museum of Nature & Science researchers discovered of a new species of cave-dwelling pseudoscorpion near the Flatirons in City of Boulder Open Space and Mountain Parks. David Steinmann, a research associate with the Zoology Department at the Denver Museum of Nature & Science, found the new pseudoscorpion along with his wife Debbie and son Nathan. The newly discovered species, Larca boulderica named after Boulder, marks the sixth cave-adapted species of the Larca genus from caves in North America.

In 2008, the Steinmann family went looking for invertebrates in a small cave west of Boulder when David saw an unusual-looking pseudoscorpion clinging to the bottom of a jagged stone. Steinmann sent the specimens to Mark Harvey, a pseudoscorpion expert at the Western Australian Museum, and Harvey determined that the tiny animals represent a new species. Harvey and Steinmann described and named Larca boulderica in a paper recently published in ZooKeys. The specimen used in the species description will now be deposited in the arachnology collection at the Denver Museum of Nature & Science.

“Dave Steinmann’s discovery of new species of pseudoscorpions from Colorado’s cave systems demonstrates how much we still have to discover about this planet’s biodiversity,” said Paula Cushing, senior curator of invertebrate zoology at the Museum. “Dave’s work in these challenging and unique habitats is critical in such discoveries.”
About the size of a sesame seed with crab-like pincers, Larca boulderica survives in dry and dusty habitats such as packrat middens. Boulder is the only place in the world they are known to live. Pseudoscorpions have been around for millions of years, including when Tyrannosaurus rex roamed the planet.

“Pseudoscorpions are fascinating creatures. They look like tiny scorpions without a stinger. Few people encounter them, and even fewer find them in caves,” said Frank Krell, senior curator of entomology at the Museum. “David Steinmann has found many tiny creatures in Colorado caves that nobody has found before. The city of Boulder is now immortalized in the name of this new species.”

It was discovered while working on the 1001 Seaforest Species project, which focuses on raising awareness about the rich kelp bed ecosystems of South Africa.

Published in the scientific journal ZooKeys, the study focuses on four species of galeommatoidean bivalves collected from the Western Cape region of South Africa. Among these is one new species, Brachiomya ducentiunus. This small clam, which is only 2 mm (less than 1/8th inch) in length, spends its life crawling between the spines of sea urchins.

The new species has so far only been found in one locality in False Bay, South Africa, where it was found attached to the burrowing sea urchin Spatagobrissus mirabilis in coarse gravel at a depth of about 3 m. It has not been observed free-living, without the host urchin.
Brachiomya ducentiunus was discovered while preparing and working on the 1001 Seaforest Species project, a research and storytelling program aimed at increasing awareness of regional kelp bed ecosystems colloquially referred to as ‘the Great African Seaforest’.

“This study marks a significant advancement in our understanding of the biodiversity and ecological interactions of galeommatoidean bivalves,” says lead author Paul Valentich-Scott. “By uncovering the hidden lives of these small but ecologically important organisms, we hope to contribute to the broader knowledge of marine biodiversity and the conservation of these unique habitats.”
Co-author Charles L. Griffiths, emeritus professor at the University of Cape Town, says, “A large proportion of smaller marine invertebrates remain undescribed in western South Africa and almost any project that samples specialized habitats turns up many new records and species.”

In a similar vein, co-author Jannes Landschoff, marine biologist at the Sea Change Trust, says “Creating foundational biodiversity knowledge is a most important step to the humbling realization of how fascinating and uniquely diverse a place is. I see this every day through our work in the rich coastal waters of Cape Town, where an extensive underwater kelp forest, the ‘Great African Seaforest,’ grows.”

All too often, researchers discover new species only to learn they are already at risk of extinction.
So when researchers from Shanghai Ocean University and Yunnan Agricultural University identified two new species from the upper Pearl River system in southwest China, they were likely unsurprised to find the fish facing major threats from pollution and overharvesting.
Beaufortiagranulopinna holotype from Lizhou River, a stream tributary of Bo′ai River of the Pearl River basin, at Tianlin County, Guangxi Province, China.
The new species, Beaufortia granulopinna and Beaufortia viridis, are members of the family Gastromyzontidae, also known as hillstream suck-loaches. They are highly specialised, with compressed bodies, flattened bottoms, and greatly expanded paired fins forming suction cup-like structures. These adaptations enable them to adhere to rocky substrates, resisting currents while feeding on algae and invertebrates.
Researchers discovered the new species during surveys studying aquatic life in various waterways in Yunnan and Guangxi between 2022 and 2024. The study, led by Jing-Chen Chen, offers new insights into the taxonomy and molecular phylogeny of the Beaufortia pingi species group, of which the two discoveries are likely members.
Beaufortiaviridis holotype from Wuming River, a stream tributary to the You River of the Pearl River basin, at Wuming District, Nanning City, Guangxi Province, China.
Although research on the Beaufortia pingi group is mostly in its initial stages, the situation is far from optimistic. These species have become popular ornamental fish in China, and aquarium trade operators reap substantial profits through their capture and sale. Among them are those who act with disregard for sustainability, using destructive harvesting practices.
Given the loaches’ preference for fast-flowing water, projects that obstruct rivers can easily lead to regional extinction. Their low pollution tolerance and sensitivity to changes in water quality also contribute to the significant reductions in population that many species are suffering.

In the habitat of B.viridis, Wuming District, Nanning City, most small tributaries have been modified into step-like reservoirs for water storage, and those near agricultural irrigation areas are polluted, rendering these areas unsuitable for their survival. Interestingly, however, a stable population was discovered inside a commercial eco-camping site left untouched to satisfy consumers’ pursuit of “pristine nature.”
The researchers suggest that future efforts should focus on increasing attention to these species, conducting fundamental research, and further exploring their scientific and economic potential. Simultaneously, it is crucial to enhance habitat conservation awareness, scientifically plan, and develop sustainably, ensuring harmonious coexistence between humans and nature.

Species of the crab family Xanthidae go by many names: gorilla crabs, mud crabs, pebble crabs, rubble crabs – the list goes on. But when it was time to name a tiny, ‘furry’ new species from China, researchers drew unlikely inspiration from the video game League of Legends.
Gothus teemo was named after the character Teemo from the immensely popular MOBA (Multiplayer Online Battle Arena) thanks to its distinctive appearance.
Gothus teemo male holotype (left), Teemo (right).
Loosely resembling a raccoon, Teemo is small and fluffy with a brown and white intermingled fur coat. The new species’ small size, densely covered short setae (bristles), and brown-striped colouration quickly drew comparisons.
Published in the open-access journal Zoosystematics and Evolution, the discovery was made during an expedition to the coral reefs of the South China Sea. There researchers discovered the new species in the Xisha Islands (Paracel Islands) and Nansha Islands (Spratly Islands).
Illustration of Gothus teemo by by Fei Gao.
The team collected specimens while scuba diving, photographing them and conserving them for further study. The specimens are now housed at the Marine Biological Museum, Chinese Academy of Sciences in Qingdao, China.
This new-to-science crab represents not only a new species, but also an entirely new genus. Sticking to a theme, researchers named the genus after a game – albeit one created 2,500 years before League of Legends!
The ancient Chinese board game, Go.
They chose the name Gothus for the genus, drawing inspiration from the ancient Chinese strategy board game, Go. The name alludes to the intermingled black and white patterns on the carapace of Gothus species, beneath which lie circular granules resembling the pieces of the game.
As part of their study, the researchers suggested the reclassification of the species Actaea consobrina into the genus Gothus. This reclassification was based on both morphological and molecular evidence.
Actaea consobrina, proposed as Gothus consobrina.
Gothus teemo is by no means the only new species named after a video game character. Just last week, we shared a story from our Biodiversity Data Journal about a blind spider named after the Monster Hunter character Khezu – check out the story below!
Gothus teemo is yet another reminder that countless unknown creatures are just waiting to be discovered. The coral reefs of the South China Sea continue to be a rich source of new and fascinating species. And, who knows, perhaps there’s a Gothus tristana out there, too.

Deep within a cave in the Du’an Yao Autonomous County of Guangxi, China, researchers discovered a pale, eyeless spider unknown to science.
This discovery, detailed in the open-access Biodiversity Data Journal adds a remarkable member to the Otacilia genus. And, as is often the case, the scientist behind the revelation turned to popular culture to name the new species.
They settled on Otacilia khezu.
Khezu in Monster Hunter.
The Khezu wyvern features in the popular video game series Monster Hunter. It is known for its blindness and unsettling appearance, just like newly discovered species. By naming the spider Otacilia khezu, the researchers highlight its troglobitic – or cave-dwelling – nature, particularly the complete absence of its eyes.
“Its long, elastic neck stretching out while it clings to a wall or the ceiling is a sight straight out of a nightmare. Make sure you do not get overwhelmed by its horrific appearance.”
Otacilia khezu, like many troglobitic creatures, lacks eyes and pigmentation, has elongated appendages, and has developed heightened sensory adaptations to navigate and thrive in its dark environment.

The research team led by Yejie Li, Langfang Normal University, note the significance of the discovery, as it marks the first recorded troglobitic Otacilia species in China. Prior to this, only two troglobitic Otacilia species had been identified, both in Laos.
The species is one of many spiders named after influential fictional characters. In fact, one spider was named after a character and the actor playing him.
The documentation and publication of this new species set the stage for further studies on the ecological roles of troglobitic spiders and their evolutionary adaptations.
Chinese civillians can rest assured that Otacilia khezu is considerably less dangerous than its namesake when they keep an eye out for the eyeless arachnid.

Researchers have described a remarkable new species of velvet worm from the Ecuadorian Amazon.
Take a look below:

While the Tiputini velvet worm (Oroperipatus tiputini) may look friendly, it is an accomplished hunter that shoots a sticky substance from a pair of glands to trap its prey.
However, lead author Jorge Montalvo from the USFQ Museum of Zoology, notes that the species also has a softer side, with the mother taking care of her considerably lighter-coloured young after they are born.
Adult female with her offspring.
Velvet worms, also known as onychophorans or peripatus, are rare and unique invertebrates often referred to as “living fossils” because they evolved over 500 million years ago, long before the appearance of dinosaurs.
Currently, only about 240 velvet worm species are known, inhabiting tropical regions in the Americas, southern Chile, Africa, Southeast Asia, Oceania, and New Zealand.

Published in the open-access journal Zoosystematics and Evolution, the discovery was more than 20 years in the making. It also represented the first study of Ecuadorian velvet worms for over 100 years.
“The research on this new species took several decades. I discovered the first individual of this new species in 2001, and we finally managed to describe it as part of Jorge Montalvo’s graduation thesis, who is now my colleague at the Museum of Zoology at USFQ. To complete the description, we used not only macromorphological descriptions but also high-magnification images obtained with a scanning electron microscope.”
Diego F. Cisneros-Heredia, one of the authors and director of the USFQ Museum of Zoology, Ecuador.
The researchers named the species after the Tiputini Biodiversity Station (TBS), part of the Yasuní Biosphere Reserve. The name recognises the hard work of the station’s management, research, and field team in protecting biodiversity.
