A new agamid joins Asia’s rich reptile fauna, officially described as new to science in the open-access journal ZooKeys.

“From 2009 to 2022, we conducted a series of field surveys in South China and collected a number of specimens of the Calotes versicolor species complex, and found that the population of what we thought was Calotes versicolor in South China and Northern Vietnam was a new undescribed species and two subspecies,” says Yong Huang, whose team described the new species.
Calotes wangi hainanensis, a newly discovered subspecies of Calotes wangi.
Wang’s garden lizard (Calotes wangi) is less than 9 cm long, and one of its distinguishing features is its orange tongue.
“Calotes wangi is found in subtropical evergreen broad-leaved forests and tropical monsoon forests in southern China and northern Vietnam, mostly in mountainous areas, hills and plains on forest edges, arable land, shrub lands, and even urban green belts. It is active at the edge of the forest, and when it is in danger, it rushes into bushes or climbs tree trunks to hide. Investigations found that the lizards lie on sloping shrub branches at night, sleeping close to the branches,” says Yong Huang.

It is active from April to October every year, while in the tropics it is active from March to November or even longer, and eats a variety of insects, spiders, and other arthropods.
For now, the researchers estimate that the new species is not threatened, but they do note that in some areas its habitat is fragmented.

“In addition, their bodies are used medicinally and the lizards are also eaten,” they write in their research paper.
This is why they suggest that the local government strengthen the protection of their ecological environment and pay close attention to the population dynamics.

Dikow, an esteemed entomologist specialising in Diptera and cybertaxonomy, is the new Editor-in-Chief of the leading scholarly journal in systematic zoology and biodiversity
Esteemed entomologist specialising in true flies (order Diptera) and cybertaxonomy, Dr Torsten Dikow was appointed as the new Editor-in-Chief of the leading open-access peer-reviewed journal in systematic zoology and biodiversity ZooKeys.
Today, Dikow is a Research Entomologist and Curator of Diptera and Aquatic Insects at the Smithsonian National Museum of Natural History (Washington, DC, USA), where his research interests encompass the diversity and evolutionary history of the superfamily Asiloidea – or asiloid flies – comprising curious insect groups, such as the assassin flies / robber flies and the mydas flies. Amongst an extensive list of research publications, Dikow’s studies on the diversity, biology, distribution and systematics of asiloid flies include the description of 60 species of assassin flies alone, and the redescription of even more through comprehensive taxonomic revisions.
During his years as a postdoc at the Field Museum (Illinois, USA), Dikow was earnestly involved in the broader activities of the Encyclopedia of Life through its Biodiversity Synthesis Center (BioSynC) and the Biodiversity Heritage Library (BHL). There, he would personally establish contacts with smaller natural history museums and scientific societies, and encourage them to grant digitisation permissions to the BHL for in-copyright scientific publications. Dikow is a champion of cybertaxonomic tools and making biodiversity data accessible from both natural history collections and publications. He has been named a Biodiversity Open Data Ambassador by the Global Biodiversity Information Facility (GBIF).
Dikow is no stranger to ZooKeys and other journals published by the open-access scientific publisher and technology provider Pensoft. For the past 10 years, he has been amongst the most active editors and a regular author and reviewer at ZooKeys, Biodiversity Data Journal and African Invertebrates.
“Publishing taxonomic revisions and species descriptions in an open-access, innovative journal to make data digitally accessible is one way we taxonomists can and need to add to the biodiversity knowledge base. ZooKeys has been a journal in support of this goal since day one. I am excited to lend my expertise and enthusiasm to further this goal and continue the development to publish foundational biodiversity research, species discoveries, and much more in the zoological field,”
ZooKeys is a peer-reviewed, open-access, rapidly disseminated journal launched to accelerate research and free information exchange in taxonomy, phylogeny, biogeography and evolution of animals. ZooKeys aims to apply the latest trends and methodologies in publishing and preservation of digital materials to meet the highest possible standards of the cybertaxonomy era.
ZooKeys publishes papers in systematic zoology containing taxonomic/faunistic data on any taxon of any geological age from any part of the world with no limit to manuscript size. To respond to the current trends in linking biodiversity information and synthesising the knowledge through technology advancements, ZooKeys also publishes papers across other taxon-based disciplines, such as ecology, molecular biology, genomics, evolutionary biology, palaeontology, behavioural science, bioinformatics, etc.
The moth, named Mirlatia arcuata, by a research team from Germany, Austria, and the United Kingdom, is one of the most remarkable discoveries in Lepidoptera of recent decades.
European Lepidoptera (butterflies and moths), with a currently known inventory of approximately 11, 000 species, are generally considered well-researched. However, a new genus and species from the Geometrid moth family described in the scientific journal ZooKeys tell a different story. The moth, named Mirlatia arcuata by a research team from Germany, Austria, and the United Kingdom, is one of the most remarkable discoveries in Lepidoptera of recent decades.
Decades-old UFO
In the early 1980s, Austrian amateur entomologist Robert Hentscholek collected three specimens of a moth species in southern Dalmatia, Croatia, which were integrated into his collection or given to colleagues without being identified. Decades later, the collection was sold to Toni Mayr, another hobbyist researcher from Austria, who immediately noticed the unusual insect that stood out from all known European species and couldn’t even be assigned to a known genus.

The collector was contacted to provide more information, and it turned out that a male and a female specimen of the same species had been given to another collector who had since passed away. The female specimen was rediscovered in 2015 in the collection of the Natural History Museum in Vienna, while the whereabouts of the other specimen remained unknown. The unique male was finally presented to the Tyrolean Federal State Museums by Toni Mayr.

In 2022, a research team was formed to identify this enigmatic moth, and it was finally described as a new genus and species in early November 2023. It was given the name Mirlatia arcuata, where Mirlatia is an aggregate of the stems of two Latin words that translate loosely as “bringing a surprise,” a reference to the surprising discovery of this curious new moth.
Cold-adapted or introduced?
Wing venation of a male Mirlatia arcuata.
The discovery of such a large and distinctive moth species in a well-explored region like southern Croatia might seem unlikely. However, according to researcher Peter Huemer of the Tyrolean State Museums (Ferdinandeum), who took part in the study, there was surprisingly little research conducted in that area during the moth’s flight season in March. “It’s possible that Mirlatia arcuata is a cold-adapted, winter-active species that would need to be sought in the middle of winter,” he says.
The hypothesis of introduction from other continents was discarded by the study authors for several reasons. Axel Hausmann from the Zoological State Collection in Munich examined all known moths from cold regions in the northern and southern hemisphere and could not identify a similar species from these regions. Furthermore, the collecting location in Podgora is not in close proximity to a port, and during the Yugoslavian era, the traffic in Dalmatian ports was rather limited. Also, Split and other Croatian ports were rarely visited by ships from other continents during the communist period. Additionally, Robert Hentscholek had never collected in the tropics, ruling out the possibility of a labeling error.
Many questions, few answers
Despite all efforts, the relationships of the new genus and species have not been definitively clarified. Even the assignment to the subfamily Larentiinae is not entirely secure and is based on a few features like wing venation. Initial genetic data from the mitochondrial COI barcode, as well as characteristics of the tympanal organ (auditory organ), point to a largely independent systematic position of the species. Further investigations of the entire genome could provide more clarity.

Even less is known about the biology of the new species, apart from the fact that its known habitat consists of coastal rock biotopes with Mediterranean vegetation. In March 2022, Slovenian lepidopterologist Stane Gomboc initiated a comprehensive search, but it turned out to be unsuccessful. It’s possible that the moth’s flight season has already ended due to climate warming.
The study authors hope they will soon rediscover Mirlatia arcuata and know more about its habitat requirements and biology.

Thanks to recently collected samples, it was described and named after its preferred habitat, the boulders surrounded by the last remaining forests at these sites.
Named after its habitat preference, Paroedura manongavato, from the Malagasy words “manonga” (to climb) and “vato” (rock), is a bouldering expert. Part of its “home range” is also very well-known to rock climbers for its massive granitic domes. “Its description represents another step into the crux (in climbing jargon, the most difficult section of a bouldering problem) of resolving the taxonomy of the recently revised P. bastardi group, where the new species belongs, and reaching a total of 25 described species in this genus, all exclusively living in Madagascar and Comoros,” says C. Piccoli from CIBIO – Research Center in Biodiversity and Genetic Resources, Portugal. She and her team just published a paper describing the new gecko.
Thus far, this species has only been found in Anja Reserve and Tsaranoro, both of which are isolated forest patches in the arid south-central plateau of Madagascar. These sites, at a distance of ca. 25 km, have a peculiar conformation, with huge granitic boulders close to rocky cliffs and surrounded by vegetation. The survival of P. manongavato, defined as microendemic for being restricted to a very narrow distributional range, thus depends on the preservation of these small forest patches. Subsequently, the authors proposed an evaluation of its conservation status as Critically Endangered, a category designated for species threatened of extinction by the International Union for Conservation of Nature.
Its discovery history is long, starting during the Malagasy summer of 2010, when the first evidence of another Paroedura species was found in Anja, together with the recently described P. rennerae in 2021. Distinguishing these two species on the field is a difficult task. Both species have prominent dorsal-enlarged keeled scales and a similar dorsal pattern, although adults of P. manongavato have an overall less spiky appearance, less contrasted dorsal markings, and a smaller body size compared to P. rennerae. The need to collect more samples brought researchers A. Crottini, F. Andreone, and G. M. Rosa to return to Anja in 2014, and collect the future holotype (i.e. the name-bearing and description reference individual) of this new species. Later in 2018, F. Belluardo, J. Lobón-Rovira, and M. Rasoazanany, visited Anja and Tsaranoro again and were able to collect several tissue samples and high-resolution photos of the reptiles living in the area, including the new gecko species. This cumulative data collection was fundamental to advance with its description.
Published in the open access journalZooKeys, this study highlights the importance of conducting herpetological inventories in Madagascar to improve our understanding of species diversity and progress with species conservation assessments. “The description of this species shows the importance of collaborative efforts when documenting biodiversity, especially for those range-restricted and isolated species at greatest risk of disappearing,” points out the leading author of this study C. Piccoli.

The species was previously known on the commercial tarantula market as the “Chilobrachys sp. Electric Blue Tarantula” but no documentation existed describing its distinctive features or natural habitat.
In an exciting discovery, a new species of tarantula with electric blue coloration was found in Thailand.

“In 2022, the bamboo culm tarantula was discovered, marking the first known instance of a tarantula species living inside bamboo stalks. Thanks to this discovery, we were inspired to rejoin the team for a fantastic expedition, during which we encountered a captivating new species of electric blue tarantula” researcher Dr. Narin Chomphuphuang said.
Following the announcement of Taksinus bambus in Thailand, he and his research team, along with JoCho Sippawat, a local wildlife YouTuber, embarked on a survey expedition in the Phang-Nga province. During their survey, they not only identified this new tarantula species by its distinctive electric-blue coloration but also discovered its unique natural history. This is the first tarantula species ever found in a Thai mangrove forest.

“The first specimen we found was on a tree in the mangrove forest. Collecting them was challenging due to the muddy and waterlogged ground. These tarantulas inhabit hollow trees, and the difficulty of catching an electric-blue tarantula lies in the need to climb a tree and lure it out of a complex of hollows amid humid and slippery conditions. During our expedition, we walked in the evening and at night during low tide, managing to collect only two of them,” Narin said.

“Allow us to introduce our exciting discovery: a new species of tarantula that exhibits a mesmerizing blue-violet hue, reminiscent of electric blue sparks. The secret behind the vivid blue coloration of our tarantula lies not in the presence of blue pigments, but rather in the unique structure of their hair, which incorporates nanostructures that manipulate light to create this striking blue appearance,” Narin said.
Blue is one of the rarest colors to appear in nature, which makes blue coloration in animals particularly fascinating. The scarcity of the color blue in nature can be attributed to the challenges associated with absorbing and reflecting specific wavelengths of light. Blue is difficult to produce in nature because, to appear blue, an object needs to absorb very small amounts of energy while reflecting high-energy blue light. This is challenging, because blue light has shorter wavelengths and higher energy compared to other colors. Generating molecules capable of absorbing this energy is complex, making blue in nature relatively rare.

In essence, what we perceive as a blue tarantula is, in fact, a result of how light interacts with the nanostructure-covered hairs on the tarantula’s body, causing some colors to cancel each other out and allowing only blue to be reflected. These biological photonic nanostructures create a remarkable iridescent effect that changes as you alter your viewing angle, making the tarantula even more captivating.

What’s even more fascinating is its ability to not only display blue but also a beautiful violet hue. Violet light occupies only a small portion of the visible light spectrum, and there are very few nanostructures precise enough to exclusively scatter violet light. Moreover, violet wavelengths are even more energetic than blue.

In terms of coloration, female and juvenile male C. natanicharum exhibit unique characteristics attributed to the presence of two distinct types of hair. Notably, they possess a more pronounced metallic-blue coloration on various parts of their bodies, while violet hues are predominantly observed in specific areas such as the chelicera, carapace, and certain leg segments. In adult male C. natanicharum, a similar coloration pattern is retained on the chelicera, carapace, and legs, although it appears less intense compared to females. Furthermore, there is a notable shift in coloration on their legs and body, transitioning to white due to the increased density of white setae.

“This species was previously found on the commercial tarantula market. There, it was known as the “Chilobrachys sp. Electric Blue Tarantula” but no documentation existed describing its distinctive features or natural habitat. The exact location where the Electric Blue Tarantula lived remained a mystery until our recent discovery. This has led us to speculate that C. natanicharum may be present in the southern region of Thailand, especially in the remaining forest areas close to where it was found,” Narin said.
The habitat of C. natanicharum includes mangrove forests (left) and highland (right) Photos by Narin Chomphuphuang
According to a study just published in the journal ZooKeys, C. natanicharum exhibits adaptability in inhabiting evergreen and mangrove forests, where tarantulas live inside tree hollows. They can be found at elevations ranging from sea level to highland areas, and live in both arboreal and terrestrial burrows within evergreen forests, at elevations of up to 57 m.
“Unlike our previous discovery, the bamboo culm tarantula, which is specifically associated with bamboo, the electric blue tarantula demonstrates remarkable adaptability. These tarantulas can thrive in arboreal as well as terrestrial burrows in evergreen forests. However, when it comes to mangrove forests, their habitat is restricted to residing inside tree hollows due to the influence of tides, and they cannot be found living terrestrially within mangroves.” Narin said.

The scientific name of Chilobrachys natanicharum was chosen after an auction campaign for naming the new species. The winner of the auction campaign was Nichada Properties Co., Ltd., Thailand, which suggested a combination of the names of Mr. Natakorn Changrew and Ms. Nichada Changrew, who are company executives.
All proceeds from the auction were donated to support the education of Lahu children in Thailand and poor cancer patients.
“The Lahu people are an indigenous hill tribe in northern Thailand (Musoe) and are known for their vibrant culture and traditional way of life. Unfortunately, many Lahu children are denied access to education due to poverty, leaving them with limited opportunities for their future. The goal is to help change this by providing educational opportunities for Lahu children, giving them a chance to break out of the cycle of poverty. Additionally, cancer remains a significant public health issue globally, affecting millions of people each year. Many cancer patients struggle with financial hardship, which can make accessing quality care even more difficult. We believe that everyone deserves access to quality healthcare, regardless of their financial situation,” the researchers write in their paper.

“We often encounter the question, ‘What are the benefits of studying new species of tarantulas?’ It’s essential for the general public to understand the significance of taxonomy as a fundamental aspect of research. Taxonomy serves a vital role, ranging from the basic, such as when people inquire on social media about the name of a spider, to conducting crucial research aimed at preserving these species from extinction.” Narin said.

Mangrove forests are invaluable ecosystems offering numerous benefits. However, they face the looming threat of deforestation, which is a destructive process caused by activities such as logging, commercial development, pollution, overfishing, and the impacts of climate change. The electric blue tarantula, the first tarantula species discovered in the mangrove forests of Thailand, is also one of the world’s rarest tarantulas. “When we examine the causes behind the decline of mangrove forests, it becomes apparent that many of these threats are human-induced, both directly and indirectly. This raises a critical question: Are we unintentionally contributing to the destruction of their natural habitats, pushing these unique creatures out of their homes? Or should we advocate for the protection of mangrove forests, not only for the sake of the Electric-Blue Tarantula but also for the preservation of this remarkable jewel of the forest?,” the researchers ask.

Today, 16 September 2023, we are celebrating our tenth anniversary: an important milestone that has prompted us to reflect on the incredible journey thatBiodiversity Data Journal (BDJ) has been through.
From the very beginning, our mission was clear: to revolutionise the way biodiversity data is shared, accessed, and harnessed. This journey has been one of innovation, collaboration, and a relentless commitment to making biodiversity data FAIR – Findable, Accessible, Interoperable, and Reusable.
Over the past 10 years, BDJ, under the auspices of our esteemed publisher Pensoft, has emerged as a trailblazing force in biodiversity science. Our open-access platform has empowered researchers from around the world to publish comprehensive papers that seamlessly blend text with morphological descriptions, occurrences, data tables, and more. This holistic approach has enriched the depth of research articles and contributed to the creation of an interconnected web of biodiversity information.
In addition, by utilising ARPHA Writing Tool and ARPHA Platform as our entirely online manuscript authoring and submission interface, we have simplified the integration of structured data and narrative, reinforcing our commitment to simplifying the research process.
One of our most significant achievements is democratising access to biodiversity data. By dismantling access barriers, we have catalysed the emergence of novel research directions, equipping scientists with the tools to combat critical global challenges such as biodiversity loss, habitat degradation, and climate fluctuations.
We firmly believe that data should be openly accessible to all, fostering collaboration and accelerating scientific discovery. By upholding the FAIR principles, we ensure that the datasets accompanying our articles are not only discoverable and accessible, but also easy to integrate and reusable across diverse fields.
As we reflect on the past decade, we are invigorated by the boundless prospects on the horizon. We will continue working on to steer the global research community towards a future where biodiversity data is open, accessible, and harnessed to tackle global challenges.
Ten years of biodiversity research
To celebrate our anniversary, we have curated some of our most interesting and memorable BDJ studies from the past decade.
Recently, news outlets were quick to cover a new species of ‘snug’ published in our journal.

We extend our heartfelt gratitude to our authors, reviewers, readers, and the entire biodiversity science community for being integral parts of this transformative journey. Together, we have redefined scientific communication, and we will continue to push the boundaries of knowledge.
A new species of spiny mouse has been discovered in Ecuador, making it the 14th of its genus to be identified in the past five years. Neacomys marci, which was previously confused with another species, is around the length of a tennis ball, with a long tail, pale suede belly fur and a white throat.

Discovered in the Chocó biogeographic region in northwestern Ecuador, it is the 24th formally recognised species in its genus, which has seen significant upheaval in recent years.
Neacomys is a widely distributed genus of small spiny or bristly rodents that occupy habitats in eastern Panama and the northern half of South America. Since 2017, studies of the genus have been remarkably dynamic, resulting in the description of several new species.

However, as there are still many unexplored areas in South America and adjacent Central America (Panama), some of the currently recognised species have not been studied thoroughly, and the true diversity of the genus may be underestimated.
The Chocó biogeographic region is considered one of the most diverse biodiversity hotspots in South America, but one of the least studied despite its great size (along the Pacific coasts of Panama, Colombia and Ecuador). The rainforests of northwestern Ecuador have high biodiversity and endemism due to the influence of the Chocó and the Andes Mountains.

Major reviews of museum collections and increased field collection efforts have helped scientists understand Neacomys marci and other species. Molecular analysis is also being used to assist with more accurate animal group identification.
The new species was named after Marc Hoogeslag of Amsterdam, the Netherlands, who was co-founder and leader of the International Union for Conservation of Nature – Netherlands Land Acquisition Fund, which helps local groups around the world establish new ecological reserves and conserve endangered species. The EcoMinga Foundation‘s Manduriacu Reserve, home to this new species, is one of many reserves that have benefited from Hoogeslag’s program.

Tom Hardy and his Marvel character Venom have given their names to a newly discovered Australian spider. The genus Venomius and its only current species Venomius tomhardyi were described following an expedition to Tasmania.
Tom Hardy portrays Eddie Brock and his alter-ego Venom, an antihero closely associated with Spider-Man, across two Marvel films and gives his name to the sole species of the new genus. The distinctive black spots on the arachnid’s abdomen reminded the scientists of Venom’s head, inspiring them to select the unusual name.

The genus belongs to the Araneidae family of spiders, or Araneae, that build upright circular webs to capture prey. Despite resembling the related genus Phonognatha as both do not have tubercles on the abdomen, the newly described spiders are distinct in their behaviour of creating silk-lined holes in the branches of trees for shelter, as well as their different genitalia.
The holotype of the new species was discovered and subsequently preserved at the Queen Victoria Museum and Art Gallery following an expedition to Tasmania, Victoria, South Australia and Western Australia.
“This is part of a long-term research that aims to document the entire Australian spider fauna, which will be of extreme importance for conservation management plans and the continuation of the decadal plan for taxonomy and biosystematics in Australia and New Zealand.”

Researchers also sourced supplementary specimens from scientific arachnology collections, with researchers examining approximately 12,000 records in Australian and overseas institutions.
“It is really important to keep describing new spiders to assess the total biodiversity of these predators in Australia,” added the study’s first author MSc Giullia Rossi.

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.
An adult female of Pulchriphyllium anangu, one of the newly described species, observed July 2016 at Kadumane Estate, India by iNaturalist user @ashwinv (Ashwin Viswanathan) https://www.inaturalist.org/observations/29374627)
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.
