An international research team including the University of Göttingen has described seven previously unknown species of leaf insects, also known as walking leaves. The insects belong to the stick and leaf insect order, which are known for their unusual appearance: they look confusingly similar to parts of plants such as twigs, bark or – in the case of leaf insects – leaves.

This sophisticated camouflage provides excellent protection from predators as well as presenting a challenge to researchers. Genetic analysis enabled the researchers to discover “cryptic species”, which cannot be distinguished by their external appearance alone. The findings are not only important for the systematic study of leaf insects, but also for the protection of their diversity. The results were published in the scientific journal ZooKeys.
Taxonomy – meaning the naming, description and classification of species – is difficult in the case of leaf insects: individuals of different species can be difficult to tell apart, yet there can be huge variations within a species. “Individuals of different species are often counted as belonging to the same species based on their appearance. We were only able to identify some of the new species by their genetic characteristics,” explains the Project Lead, Dr Sarah Bank-Aubin, Göttingen University’s Animal Evolution and Biodiversity Department.

Some individual insects from India were previously thought to belong to a species that is widespread in Southeast Asia. But now the researchers have found out that they are a completely new species of leaf insects. Bank-Aubin emphasises: “The finding is important for species conservation: if all the individuals die out in India, it is not just a group within a species that is reduced, as was previously thought. In fact, a whole distinct species is being wiped out. This means that the Indian species is particularly important to protect.” Other newly discovered species come from Vietnam, Borneo, Java and the Philippines.

The researchers from Göttingen University worked with leaf insect expert Royce Cumming, City University New York. This research collaboration has led to the identification of over twenty new species. Dr Sven Bradler, who has been researching the evolution of stick and leaf insects at the University of Göttingen for more than 20 years, explains: “There are around 3,500 known species of stick and leaf insects and there are currently just over 100 described species of leaf insect. Although they only make up a small fraction of this diverse family of insects, their spectacular and unexpected appearance makes them unique.”

In the latest issue (1174th) of the scientific open-access journal ZooKeys, you can find our paper describing a new species of tarantula (family Theraphosidae) found in northwestern Iran.
This species belongs to Chaetopelma, a relatively small genus, distributed in Crete, Sudan, and the Middle East, and one of the only two tarantula genera inhabiting the Mediterranean region.
Our discovery is significant for several reasons. Firstly, it marks the first record of this genus in Iran and the third known species of tarantulas in this country. Additionally, it extends the known range of Chaetopelma spiders by almost 350 km eastwards.
We named this species Chaetopelma persianum, paying homage to its occurrence in Iran, which has historically been known as Persia. As a potential common name, we suggest “Persian Gold Tarantula”, where we are also making a reference to the “woolly, golden hairs’’ on its carapace.

For the purpose of our study, we only had one specimen: a female with a leg span of almost 9 cm, available. Yet, its distinct characteristics allowed us to confidently differentiate it from other known Chaetopelma species.
This tarantula is an obligate burrower and inhabits high elevations in well-vegetated mountainous regions of the northern Zagros Mountains. The holotype specimen was collected from a self-made ground burrow on sloped rocky ground, amidst sparse low vegetation and grasses.
It all started with local nature enthusiast Mehdi Gavahyan, who photographed a wandering male and sent me the photo. When I figured it was most likely an undescribed species, I asked him to team up with Amir Hossein Aghaei, a nature enthusiast and a friend of mine, and send me specimens of these spiders for further examination. Unfortunately, they only managed to collect that one female. However, it turned out to be enough for us to describe the Persian Gold Tarantula!
Additionally, thanks to local citizen scientists and naturalists, we later also got hold of photos of another two males of the same genus, taken very close to the type locality of the new species: one in Sardasht in West Azerbaijan Province of Iran, and the other in the surroundings of Sulaymaniyah in Iraq. While it is highly probable that both these males belong to Ch. persianum, this cannot be confirmed until further examination of collected material from both sexes is conducted.

During our research, we also noted that one species of Chaetopelma described from Cameroon is misclassified and should be transferred to another genus. However, this transfer is pending until the type material undergoes examination.
Looking ahead, we believe that more comprehensive investigations employing integrative methods would greatly benefit the taxonomy of Chaetopelma.

For example, Ch. olivaceum, a species with seven junior synonyms and one of the broadest ranges within the entire family, covering an area of approximately 1,493,978 km2, might potentially have cryptic species within its range. Moreover, the disjunct distribution of Ch. olivaceum in Turkey, where it occurs both in the southern regions and as far north as Istanbul, raises the possibility of distinct species status for the latter population, which is geographically isolated from the rest of the recorded occurrences. Integrative studies incorporating molecular data could offer insights into this.
Additionally, further collection efforts in lesser-sampled or completely unexplored regions, such as Saudi Arabia, Syria, Iraq, eastern Turkey and western Iran, could lead to the discovery of additional Chaetopelma species or records. These findings would be instrumental in gaining a more comprehensive understanding of the taxonomy and distribution of this genus.
When people think about corals, most picture the multi-hued reef-builders that reside in balmy waters off tropical beaches. But not all corals stick to the shallows. For example, most members of the order Antipatharia do not live within 160 feet of the surface. Some even reside at depths deeper than 26,000 feet. Commonly known as black corals due to their ink-colored skeletons, these corals are staples of deep-sea ecosystems around the world.
However, black corals remain enigmatic due to the challenges of studying them in the deep sea. This makes it difficult for scientists to assess how black corals, whose skeletons (which are made out of chitin, the same material that composes an insect’s exoskeleton) are prized components of jewelry, are responding to threats like poaching, ocean acidification and climate change.
“Describing these species is fundamental information to make conservation decisions,” said Jeremy Horowitz, a postdoctoral researcher at the National Museum of Natural History who specializes in studying black corals. “You have to know it before you can protect it.”

In a paper published this week in the journal ZooKeys, Horowitz and his colleagues at the museum and the University of Puerto Rico described Aphanipathes puertoricoensis, a new species of black coral that sports branching features found in multiple coral groups that diverged roughly 100 million years ago.

The new black coral species was discovered in April 2022 during a joint Smithsonian and National Oceanic and Atmospheric (NOAA) expedition to a stretch of the Caribbean Sea just south of Puerto Rico. Here, the seafloor bottoms out into a network of deep-sea canyons and seamounts that remain largely unexplored.
The expedition, led by research zoologist Andrea Quattrini, the museum’s curator of corals and one of Horowitz’s co-authors on the new paper, aimed to explore some of this abyssal terrain and catalog some of the creatures that reside there. Many of these animals live far deeper than human divers can go. So the researchers deployed a remotely operated unmanned vehicle (ROV) called the Global Explorer to depths as deep as 4,000 feet below the ocean’s surface.

Over seven dives, the ROV mapped 180 square nautical miles of the deep-sea floor. It collected a suite of biological samples and hours of footage for the researchers to parse on the research vessel above. They observed ghostly, blob-like predators called tunicates, gangly bristle stars, vibrant comb jellies and tiny crustaceans with fused eyes that live inside glass sponges. They even collected a colony of small invertebrates called bryozoa that had not been collected since a Smithsonian expedition to the Puerto Rico Trench in 1933.

They also found a multitude of species new to science. While exploring a canyon nearly 1,200 feet below the surface, the ROV came across a scraggly patch of black coral reminiscent of a deep-sea tumbleweed. As the ROV snipped off one of the coral’s spindly branches, Quattrini sent Horowitz, who was back in Washington, a picture of the coral on the ROV’s live feed. “She shared a picture of this coral and I immediately had no idea what it was,” Horowitz said.
When the expedition’s trove of specimens arrived in Washington, Horowitz could finally take a closer look at the puzzling coral. With long, coiled branches emanating from a short stalk like a tiny tree, the coral sported features found in multiple genera, or groups, of black coral that diverged long ago.

To assign the new species in the right group, Horowitz placed a fragment of the coral specimen underneath a high-powered scanning electron microscope at the museum. That gave him a microscopic view of the miniscule spines that line the coral skeleton. Like a fingerprint, a coral species’ spines have their own distinct shape. Comparing these spines to known black coral species allowed Horowitz to get a better idea of where this new species may slot into the black coral family tree. To be sure, the researchers also used cutting edge techniques to compare the new species’ genetic code with other corals.
All this work allowed the researchers to find a taxonomic home for the new species in the genus Aphanipathes. They christened the black coral with the species name puertoricoensis in homage to the island near where it was found.

Horowitz believes its resemblance to other groups of black coral reveals how helpful a simple body type is for survival in the deep-sea. “This simple morphological structure is evolving over and over again, probably because the conditions are the same in these different areas,” he said. “This simple structure is what works.”
The team is still examining the specimens collected and expects to name additional new species in the near future. There are also plans to go back and conduct further field research in the deep-sea canyons and ridges off Puerto Rico. “Every time we go back to this region, we find new species,” Horowitz said.
But there is also plenty to uncover closer to home. The piece of black coral from Puerto Rico recently joined the museum’s 4,000 other black coral specimens — the largest such collection in the world. Many of these black coral specimens likely represent undescribed species hiding in plain sight. According to Horowitz, “we don’t even have to go offshore to find new species.”

In busy Los Angeles, few people pay attention to what’s under their feet, but a new underground movement has people looking at the subterranean world just below the surface. A team of scientists discovered a new species of millipede crawling just beneath the soil surface in Los Angeles and Orange counties.
These never-before-seen creatures are pale, blind, thin, inch-long burrowers with the ability to produce a silk-like sticky substance, similar to spider silk. Measuring in at 0.5 millimeters wide and 2 1/2 centimeters long, these creatures are about the width of the a thin graphite lead of a mechanical pencil and about as long as a small paperclip.

Despite being so small, they are described as having a gaping toothy mouth and over 480 legs. The species in question is called the Los Angeles Thread Millipede, formally named Illacme socal.

“We hope that this discovery will encourage conservation efforts to protect these unique creatures and their habitats,” said Marek. “The discovery of Illacme socal highlights the importance of research into subterranean fauna.”
The discovery of Illacme socal was made possible by funding from the National Science Foundation. The research team included scientists from Virginia Tech, West Virginia University, and the University of California, Berkeley. The findings were published in the journal ZooKeys.
The team captured a video of the millipede burrowing and moving through small spaces and crevices underground. This is the first-ever video of this species in action and provides insight into the unique behaviors of these fascinating creatures.
This research discovery highlights the importance of habitat preservation efforts to protect the environment and prevent the loss of biodiversity. The millipede was found in two parks in the Los Angeles and Orange counties but almost certainly lived in other parts of the metropolis in the past.
The fact that populations of this species is living in two small well-known areas that are near constant development emphasizes the need for conservation efforts to protect this and other threatened organisms.

The Colombian Pacific region, nestled within the heart of the Chocó Biogeographic Region, has unveiled some of its remarkable biological wonders. Recognized as one of the world’s most enigmatic biodiversity hotspots, this area has remained largely unexplored, particularly when it comes to spider diversity. A groundbreaking biological expedition, conducted at the Jardín Botánico del Pacífico (JBP) in Bahía Solano, has revealed some taxonomic novelties that are set to redefine our understanding of this captivating ecosystem. The area not only serves as a tourist attraction but also plays a pivotal role in the conservation of the tropical rainforests and mangroves in the region.
Led by a team of dedicated researchers, the study focused on Mygalomorphae spiders, aiming to shed light on their intricate world. This enigmatic spider group includes tarantulas, trapdoor spiders, funnel-web spiders, millimeter-sized spiders with little use of the silk, and bald-legged spiders with the ability to attach substrate to their bodies. They are predatory, mostly terrestrial, and very often have restricted geographic distributions and high levels of endemism.
In this first-of-its-kind exploration of the Colombian Pacific rainforest, the team discovered and documented four remarkable spider species. One of them is Ummidia solana, an exceptional trapdoor spider. Additionally, the researchers identified three species of tarantulas: Euthycaelus cunampia, Neischnocolus mecana, and Melloina pacifica.

“These taxonomic breakthroughs represent the first recorded instances of their respective genera in the region, expanding their geographical distribution. Each species was meticulously illustrated, described, and scientifically discussed, offering valuable insights into their morphological characteristics, taxonomy, and biogeography. The results of this study serve as a significant contribution to our understanding of the region’s biological diversity, known for its exceptional species richness and endemism,” say the researchers.

Let us delve deeper into the newfound species. Ummidia solana, derived from the municipality of Bahía Solano, captures the essence of the stunning Colombian Pacific coast, with its mesmerizing landscapes and abundant vegetation. This discovery also marks the first record of the Ummidia genus within the Chocó Biogeographic Region.
Melloina pacifica, named after the Colombian Pacific region it inhabits, represents the first described species of the Melloina genus in Colombia. While Melloina is known to thrive in diverse ecosystems, including caves, this specific record expands the genus’ known distribution, previously documented solely in Venezuela and Panama.

Euthycaelus cunampia pays tribute to Don José and Don Antonio, members of the Emberá indigenous community from Mecaná, Chocó. Their transition from hunting traditions to becoming touristic and academic guides for the JBP inspired the species name. Notably, this discovery marks the first published record of the Euthycaelus genus and the subfamily Schismatothelinae outside the Andean Region and Eastern Cordillera for Colombia.

Lastly, Neischnocolus mecana, named after a township in Bahía Solano, underscores the commitment of the Jardín Botánico del Pacífico community to conserve the region’s rich biodiversity. This is the fourth described species of the Neischnocolus genus in Colombia and represents its first record in the Chocó biogeographic region and the Colombian Pacific. Notably, this description expands the known geographic range of the genus.
“This groundbreaking study serves as a testament to the potential existence of undiscovered species and the need for comprehensive taxonomic research,” the scientists say in conclusion.

A spectacular crocodile newt from the Central Highlands of Vietnam was just published in the international peer-reviewed open-access academic journal ZooKeys.
“It is an exceptional discovery as it is one of the most colourful species in the genus Tylototriton. This is also the first time that a crocodile newt species is recorded from the Central Highlands of Vietnam. Occurring at elevations from 1,800 to 2,300 m above sea level, this discovery sets an elevational record for the genus in the country, with former distribution ranges between 250 m and 1,740 m.”
says discoverer and first author of the study Trung My Phung.
Furthermore, the discovery by the Vietnamese-German researcher team, which was supported by the Vietnam Academy of Science and Technology and the Cologne Zoo (Germany), represents the southernmost distribution range of the genus known to date.
The habitat of the new species is located approximately 370 air km away from the nearest Tylototriton population, which makes it an important discovery in terms of evolution and zoogeography.
The name “ngoclinhensis” refers to the type locality of the new species, Ngoc Linh Mountain. Restricted to evergreen montane forest, the Ngoc Linh Crocodile Newt is currently known only from the Ngoc Linh Nature Reserve, Kon Tum Province, in the Central Highlands of Vietnam. This is the eighth salamander taxon described from Vietnam, and is the thirty-ninth Tylototriton species officially recognized.

Crocodile newts, scientifically known as the genus Tylototriton,include nearly 40 species inhabiting montane forest areas throughout the Asian monsoon climate zone. Remarkably, 15 of these species have been described in the past five years, and there remain several unnamed taxa, which contain cryptic species that are morphologicallydifficult to distinguish.
Established in 1986, Ngoc Linh Nature Reserve is a key biodiversity area for rare species like the endangered Golden-winged Laughingthrush and the Truong Son Muntjac. The Ngoc Linh Crocodile Newt certainly will represent another flagship species of this protected area and its surroundings, say the researchers.
“[The Central Highlands is] where the highest amphibian species diversity was recorded for Vietnam, with 130 species, while also containing the highest number of regionally occurring, micro-endemic amphibians, amounting for 26 species,”
This recent discovery is another remarkable case, “demonstrating that the Central Highlands play a special role in Vietnamese amphibian diversification and evolution,” by the words of co-author Dr. Cuong The Pham from IEBR.
The Ngoc Linh Crocodile Newt belongs to the group of range-restricted, so-called micro-endemic species, which face the greatest risk of extinction because of their presumably small population size. Unfortunately, on top of its special zoogeographic situation and rarity, its particularly colorful appearance will likely make it highly attractive to illegal collectors.
“Therefore, this discovery is of high conservation relevance,”
Now, conservation activities on site have priority, but the team is already working on breeding conservation measures, which is in line with the One Plan Approach to Conservation, developed by IUCN’s Conservation Planning Specialist Group, which combines in-situ and ex-situ efforts and various expertises for the optimum protection of a species.
“This has already been successfully implemented for another recently discovered, micro-endemic crocodile newt species from Vietnam, Tylototriton vietnamensis, of which already more than 350 individuals could have successfully been reproduced at the Cologne Zoo in Germany and also at the Melinh Station for Biodiversity in Vietnam, which is a promising example for IUCN’s Reverse the Red campaign and the idea of the conservation zoo”,
says Prof. Dr. Thomas Ziegler, Vietnam conservation team member and coordinator from Cologne Zoo, Germany.

“Brian has provided critical support to visiting researchers for many years,” writes the team of researchers in their new study in the journal ZooKeys.
When introducing a new species to science, taxonomists always get to choose its scientific name. And while there are some general rules to naming, there’s also relative freedom. Often, new species are named after the area where they were found, or their key diagnostic features, but researchers may also choose names that recognize those who helped or inspired them in their career: prominent scientists, celebrities, and, sometimes, their grandma, or their dog. In Amazonia, a new species of butterfly was discovered whose name honors the decades-long work of someone who has worked patiently behind the scenes in museum collections to provide invaluable support to researchers.
Caeruleuptychia harrisi
Caeruleuptychia harrisi was named in recognition of Brian P. Harris, museum specialist at the Smithsonian National Museum of Natural History, “for his tireless effort in facilitating butterfly research at USNM by going above and beyond to support visiting researchers,” according to a study which was just published in the journal ZooKeys. “Brian has provided critical support to visiting researchers for many years, including several co-authors on the paper,” writes the team of researchers, led by Harvard University’s Shinichi Nakahara.
In fact, Harris personally collected the type specimen that later facilitated the scientific description of the new species. After collecting it in Brazil, he deposited it at USNM, where it could be studied as a reference for this species.

“I think it is really important to recognize someone who has dedicated а good amount of his lifetime providing technical help to support research,” says Shinichi Nakahara.
Brian Harris started working at the Smithsonian Institution in July 2005. There, he served as a museum specialist for Lepidoptera (moths and butterflies) and Hymenoptera (ants, bees, and wasps) until he retired in July 2019.
Caeruleuptychia harrisi
“Brian’s job curating Lepidoptera and Hymenoptera collections is critical for us visiting researchers to conduct research based on these specimens, but sadly this kind of technical support is often not well recognized well in the current scientific community,” says Shinichi Nakahara. “I visited the Smithsonian’s Lepidoptera collection three times, in 2015, 2018, and 2023 (after his retirement!), and Brian provided me with the best support I could ever receive in all of these three visits. It was evident to me that he wanted us visitors to make the most out of the collections and he went out of his way to support my short visits to the collection.”
“He always communicated with me in advance about which butterfly group I wanted to examine, would set up an imaging system in advance, and even tried to help me find field notes left by a deceased collector by taking me to the stock room and spending time exploring the museum with me!,“ he adds.
Before working at the Smithsonian Institution, Brian Harris spent 18 years at the Natural History Museum of Los Angeles County (LACM). In the mid-1970s and early 1980s, he played drums for a band before starting at LACM.

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

The central region of Texas is a known hotspot of biological wonders. For the last five years, Dr. JoVonn Hill, an Assistant Professor and Director of the Mississippi Entomological Museum (MEM) at Mississippi State University, and his colleagues have made scientific expeditions to the area that have now revealed an extraordinary find.
The team uncovered seven previously unknown flightless grasshopper species, six of them endemic to the Edwards Plateau, which underscores the region’s extraordinary biodiversity.
With this discovery, Dr. Hill is paying tribute to two iconic musicians. In recognition of the “immense contributions” of Texas legends Willie Nelson and Jerry Jeff Walker, he has named two of these flightless grasshopper species after them.

“Melanoplus nelsoni and Melanoplus walkeri immortalize the enduring contributions of these legendary musicians and their connection to Texas,” he says.
Melanoplus walkeri.
“After these last few summers [of field studies], just like Mr. Nelson, we too have a little Texas in our souls,” he writes in his study, which was just published in the journal ZooKeys.
On Melanoplus walkeri, he writes: “Walker’s songs such as Hill Country Rain, Leavin’ Texas, and Sangria Wine brought me and my field team joy while traveling between field sites and added to the amazing ambiance of the Edwards Plateau.” In fact, the artist recorded his most influential album not far away from the spot where the new species was discovered.
Additionally, the team acknowledges the cultural heritage and deep connection to the region of the Comanche and Tonkawa tribes, naming two species after them, Melanoplus commanche and Melanoplus tonkawa respectively.
“These designations recognize the profound historical and cultural significance of the tribes in the region,” Dr. Hill explains.
Melanoplus tonkawa.
“These seven newly described species, alongside two preexisting ones, form a cohesive species group, highlighting their shared characteristics and evolutionary relationships,” Dr. Hill says in conclusion. “The formation of this new species group presents a significant contribution to our understanding of the diverse ecosystems present in central Texas,” he adds.
Melanoplus commanche.
The discovery of these seven flightless grasshopper species and the formation of a new species group underscore the ecological uniqueness of central Texas, Dr. Hill says. He and the staff of the Mississippi Entomological Museum remain committed to scientific exploration and understanding, promoting the conservation of biodiversity, and inspiring a sense of wonder and appreciation for the natural world.
