Its name pays homage to the dark wizard Lord Voldemort, the fearsome antagonist of the Harry Potter series, drawing parallels with the ant’s ghostly appearance.
In the sun-scorched Pilbara region of north-western Australia, scientists have unearthed a mysterious creature from the shadows – a new ant species of the elusive genus Leptanilla.
The new species, Leptanilla voldemort – L. voldemort for short – is a pale ant with a slender build, spindly legs, and long, sharp mandibles. The species name pays homage to the dark wizard Lord Voldemort, the fearsome antagonist of the Harry Potter series, drawing parallels with the ant’s ghostly and slender appearance, and the dark underground environment, from which it has emerged.
Leptanilla voldemort was discovered during an ecological survey to document animals living belowground in the arid Pilbara region of north-western Australia. Only two specimens of the bizarre new ant species were found. Both were collected in a net that was lowered down a 25-metre drill hole and skilfully retrieved while scraping against the hole’s inner surface – an innovative technique for collecting underground organisms known as ‘subterranean scraping’.

Compared to other Leptanilla antspecies, L. voldemort has an extremely slender body as well as long, spindly antennae and legs. Together with its collection from a 25-metre-deep drill hole, this unusual morphologyhas left experts speculating as to whether it truly dwells in soil like other Leptanilla species, or exploits a different subterranean refuge, such as the air-filled voids and cracks that form within layers of rock deeper underground.

The long, sharp jaws of L. voldemort, however, leave little to the imagination.
“Leptanilla voldemort is almost surely a predator, a fearsome hunter in the dark. This is backed up by what we know from the few observations of specialised hunting behaviours in other Leptanilla antspecies, where the tiny workers use their sharp jaws and powerful stings to immobilise soil-dwelling centipedes much larger than them, before carrying their larvae over to feed on the carcass” said Dr Wong, lead author of the study.

The exact prey of L. voldemort, however, is not known, though a variety of other subterranean invertebrates, including centipedes, beetles and flies, were collected from the same locality.
There are over 14,000 species of ants worldwide, but only about 60 belong to the enigmatic genus Leptanilla. Unlike most ants, all species of Leptanilla are hypogaeic – their small colonies, usually comprising a queen and only a hundred or so workers, nest and forage exclusively underground. To adapt to life in darkness, Leptanilla workers are blind and colourless. The lilliputian members of the ant world, these ants measure just 1 to 2 millimetres – not much larger than a grain of sand – allowing them to move effortlessly through the soil. Due to their miniscule size, pale colouration, and unique underground dwellings, finding Leptanilla species is a challenge even for expert ant scientists, and much of their biology remains shrouded in mystery.
While Australia boasts some of the highest levels of ant diversity in the world – with estimates ranging from 1,300 to over 5,000 species – L. voldemort is only the second Leptanilla species discovered from the continent. The first, Leptanilla swani, was described nearly a century ago – from a small colony found under a rock in 1931 – and has almost never been seen since.
With its formation beginning approximately 3.6 billion years ago, the Pilbara is one of the oldest land surfaces on Earth. Despite the scorching summers and meagre rainfall, the region harbours globally important radiations of underground invertebrates. Adding to the unique biodiversity of this ancient landscape, the discovery of the enigmatic ant L. voldemort is a testament to the wizardry of nature and the mysteries of life in the depths of darkness.

The papillated redbait is a member of the family Emmelichthyidae. There are only 18 known species in this family, which are commonly called redbaits, rovers, or rubyfishes. These deepwater species can be found in warm, tropical waters and are usually bright shades of red, orange, and pink.
How did Bemis and her team make this remarkable discovery? To find out, we’ll have to first travel to a fish market in the Philippines.
A molecular mystery
As part of an interagency campaign to create a reference library of fish DNA “barcodes,” Bemis and her colleagues regularly travel abroad to collect fish specimens. Some come from seafood markets overseas where they are being sold for food. In the field, these new specimens are assigned a preliminary species identification. Then, they’re transported to the Smithsonian Institution and National Systematics Laboratory for genetic sequencing, data collection, and a secondary species confirmation.

Since getting involved with this project in 2021, Bemis and teammate Dr. Matthew Girard of the Smithsonian National Museum of Natural History have analyzed thousands of samples. None have made a bigger splash, though, than two small pink fish collected from a Philippine fish market on the island of Cebu.
While collecting data from these specimens, Girard made an exciting observation. Their genetic sequences did not match their initial species identification as golden redbaits—or any other species in the genetic library, for that matter. So which species did Girard and Bemis have on their hands?

In search of answers, Bemis and Girard examined other aspects of the specimens’ biology, including their anatomy. They discovered that these fish differed from the golden redbait in several ways, including:
A different number of gill rakers, structures inside the mouth that help fish to feed
A different number of pectoral fin rays
Two fleshy structures called papillae on the pectoral girdle
These differences, combined with the genetic data, provided evidence that the two specimens were not golden redbaits, but a previously undiscovered species. With only two confirmed specimens, Bemis and Girard wondered if other individuals could be identified in global natural history collections.

After some detective work, Bemis and Girard spotted a third specimen they hypothesized might also be the undescribed species. A fish with similar color also identified as a golden redbait had been collected from a fish market in the Philippines by the Kagoshima University Museum in Japan. Bemis and Girard studied the specimen and confirmed their hypothesis with genetic and anatomical data. This specimen became the third record of papillated redbait and, ultimately, the holotype for the species—the specimen upon which a new species description is based.
More to discover
Even after describing new species, there’s always more to learn. Bemis and Girard are energized that there is still much to discover about the papillated redbait and the redbait family, which is relatively poorly known. Any opportunity to add to this small body of knowledge and study redbait species in greater detail is valuable. “I’ve had researchers that work on fish taxonomy say to me, ‘I didn’t even know this family existed.’ That’s how little we know about this group,” Girard emphasizes.
Bemis also notes that because data on the papillated redbait comes from only three specimens purchased in fish markets, she still has lots of questions. For example, Bemis says that they don’t yet know if the new species occurs outside Philippine waters, or the exact habitat in which they occur. “We also don’t know anything about their reproduction or what they eat—really basic aspects of their biology remain to be studied. Now that we recognize that it is different, we only have more to study as new specimens of papillated redbait are collected,” Bemis says.
“It is always a happy and productive moment working with U.S. scientists,” says Dr. Mudjekeewis “Mudjie” Santos of the Philippine National Fisheries Research and Development Institute. Santos was instrumental in the collection of specimens, providing fisheries data on the papillated redbait, and coining a name for the new species in Tagalog, the national language of the Philippines.

One thing is for certain, though. There are more species just waiting to be discovered, and they might be right under our noses. “I think the craziest thing is that the papillated redbait is a new species that came from a market,” Girard says. “The fact that there are undescribed species being sold without us even realizing it underscores how much we still have to learn about marine biodiversity.”

European researchers have discovered a new species of osmiine bee with an unusual geographic distribution.
Hoplitis onosmaevae is currently found exclusively in the Mercantour National Park in the French Alps and disparate mountainous regions in Turkey and Northern Iraq. The distance of more than 2000 km between these areas highlights a significant biogeographic disjunction.
Distribution map of Hoplitisonosmaevae.
Described in the open-access journal Alpine Entomology, the new bee species demonstrates unique ecological characteristics such as its distinct nesting behaviour in dead wood.
Presumed to only harvest pollen from Onosma species, it has a long proboscis, which is likely an adaptation to collect nectar from the long-tubed flowers of this genus.
Male Hoplitisonosmaevae with unfolded proboscis.
The strongly disjunct distribution of Hoplitis onosmaevae has important implications for conservation. The species likely has a very narrow ecological niche, making it highly susceptible to future changes in its habitats, for example due to changes in agricultural practices or to climate change.

“The consideration of the few known populations of this species in France is very important in the conservation field,” says lead author Matthieu Aubert, freelance entomologist and member of the Observatoire des Abeilles association.
“This study highlights the incredible diversity of wild bees and that we still have a lot to learn from our environment, even in western Europe,” he continues.
The researchers emphasise the need for detailed conservation plans in the southwestern Alps to ensure the survival of Hoplitis onosmaevae, considering its highly specialised ecological niche and consequently its vulnerability to habitat changes. Their proposals for initial conservation steps can be found in the full research paper.

In 2023, the world of biodiversity saw some amazing discoveries . Our taxonomy journals published hundreds of new species, so selecting a Top Ten was tough, but here we go – get to know these beautiful new species, and maybe think about all the amazing diversity that still remains unexplored on our planet.
10. The walking leaf
It’s very often that undescribed species hide in plain sight for years, but it’s easy to understand why when they look like that! Leaf insects look confusingly similar to leaves – this sophisticated camouflage provides excellent protection from predators, but also presents a challenge to researchers.
“There are around 3,500 known species of stick and leaf insects and there are currently just over 100 described species of leaf insect,” researcher Dr Sven Bradler says. This is why when Phyllium ortizi and six other leaf insect species were found, it made for a really special discovery.
Lime-green in colour, Phyllium ortizi is so far only known from Mindanao Island, Philippines.
The Eastern Forest Hedgehog (Mesechinus orientalis) was discovered in southwestern China. It is a small-bodied hedgehog, smaller than most of the other species in its genus, its spines as short as 1.8-2 cm. It has a brown nose, with black whiskers that shorten towards the nose.
The species is currently known from southern Anhui and northwestern Zhejiang, where it lives in scrubland and subtropical broad-leaf evergreen forests at elevations from 30 to 700 m.
The researchers found out that genus Mesechinus, to which the new species belongs, dates back to the early Pleistocene and started appearing around 1.71 million years ago, while M. Orientalis diverged from its congeners some 1.1 million years ago.

8. The bumpy salamander
Tylototriton zaimengwas found in the eponymous Zaimeng lake in Manipur, India. It is a medium-sized salamander has a massive wide head that could take up as much as a quarter of its total length. Its most distinctive feature are the knob-like warts along its body.
The salamander has an earthy-brown body with orange markings along its head and orange-brown warts down its back and sides. Its tail fades from brown at the base to yellow-orange at the tip.
#NewSpecies! New crocodile newt from India just snuck in:
An unexpected discovery, this new treefrog species was found in the Amazon lowlands of central Peru. The research team, led by Germán Chávez, was surprised that a new species could be hiding in plain sight in an otherwise well-explored part of the Amazon. No matter how many times they returned to the site, they only found two specimens, which made its scientific description challenging.
Its name, Scinax pyroinguinis, literally means “groins of fire”. It is a reference to the orange, flame-like pattern on the groins, thighs and shanks, but also to the wildfires in the area where it was found, which are a serious threat to its habitat.
Pinguicula ombrophila is part of the butterwort family, a group of insectivorous flowering plants consisting of around 115 species. Its leaves have a sticky texture, enabling it to capture and digest small insects.
For carnivorous plants, insects can be an additional source of nutrients to help them compensate the nutrient deficiency of the substrate they’re growing in. This gives them a competitive advantage over other plants and enables them to thrive in challenging habitats.
While the majority of butterworts are found in the northern hemisphere, this species was discovered in the elevated regions of southern Ecuador, near the Peru border. The research team found it on a nearly vertical rock face at 2,900 metres. Its name means “rain-loving butterwort”, highlighting the plant’s preference for very wet conditions.
Sinocyclocheilus longicornus(from the Latin words “longus”, meaning long, and “cornu”, meaning horn) comes from Southern China. It is only known from a dark vertical cave at an elevation of 2,276 m in the province of Guizhou. It is around 10-15 centimeters long and lacks pigmentation in its scales, which gives it it a ghostly whitish appearance. Since its eyes are small and probably not much help in a completely dark environment, it relies on barbels that look like tiny whiskers to feel its way around.
The researchers that found it are not quite sure what its “horn” is used for, but it might have something to do with navigating its way in the dark and dreary environment it inhabits.
Sinocyclocheilus longicornus is also featured in the SHOALS report on freshwater fish species described in 2023.
Sibon irmelindicaprioae was described as a new species together with four more tree-dwelling snake species from jungles of Ecuador, Colombia, and Panama. They all belong to Dipsadinae —a subfamily of snakes found in North and South America.
Also known as DiCaprio’s snail-eating snake, this species was named after actor and film producer Leonardo DiCaprio’s mother, Irmelin DiCaprio. The actor himself chose the name to honour his mother and raise awareness about the threats these snakes face.
Its habitat in Panama is affected by large-scale copper mining. The open-pit mines, some of them visible from space, make the areas uninhabitable for snail-eating snakes.
“These new species of snake are just the tip of the iceberg in terms of new species discoveries in this region, but if illegal mining continues at this rate, there may not be an opportunity to make any future discoveries,” says Alejandro Arteaga, who led the study to describe them.

3. The Tolkien frog
You probably guessed it by now – this stream frog from the Ecuadorian Andes was named after J.R.R. Tolkien, the author of The Hobbit and The Lord of the Rings.
At about 66 millimeters (2.5 inches) long, Hyloscirtus tolkieniis tiny enough to fit in the palm of your hand, but that doesn’t stop it from being simply stunning. With pale pink eyes and gold-speckled toes, it looks like it came straight out of Middle-earth. It was found at an elevation of 3190 meters in Río Negro-Sopladora National Park, a protected area of páramo and cloud forests.
I'm at a nerd convention today so here's the nerdiest frog I could find. Frog of the day is Hyloscirtus tolkieni, named for J. R. R. Tolkien. Photo is from the paper describing its recent discovery! https://t.co/DsQmzm7Np2pic.twitter.com/fpKBST6Uux

“The new species of frog has amazing colours, and it would seem that it lives in a universe of fantasies, like those created by Tolkien. The truth is that the tropical Andes are magical ecosystems where some of the most wonderful species of flora, funga, and fauna in the world are present. Unfortunately, few areas are well protected from the negative impacts caused by humans. Deforestation, unsustainable agricultural expansion, mining, invasive species, and climate changes are seriously affecting Andean biodiversity”, said Diego F. Cisneros-Heredia, one of the researchers behind this discovery.

2. The enigmatic Nautilus
2023 was a great year for nautilus biodiversity: three species were described as new to science, including Nautilus samoaensis, which you see here. Like its name tells you, it was found off the coast of American Samoa.
Studying nautilus diversity is no easy feat – with setting spiky traps, hauling them over on board, and, eventually, burping nautiluses, it is surely a memorable experience.
Judging by the fossil record, nautiloids were once quite plentiful throughout the oceans. Today, however, they are represented by just a handful of species.
In addition, these fragile animals remain threatened by wildlife trade as they are hunted for their shells, which according to Mongabay can sell for up to about $1,000 each on the black market.
Found in Thailand’s Phang-Nga province, Chilobrachys natanicharum features an enchanting phenomenon: a neon blue-purple coloration that gives it a unique look.
There is no blue pigment in this tarantula’s body: the secret behind its striking color comes from the unique structure of its hair, which incorporates nanostructures that manipulate light in an effect that creates the blue appearance. Depending on the light, it can also appear violet.
Before it was described as a new species, Chilobrachys natanicharum was actually known to experts from the commercial tarantula trade market as “Chilobrachys sp. Electric Blue Tarantula,” but this is the first time that it’s discovered in its natural habitat.
Its name, in fact, resulted from an auction campaign, the proceeds from the auction have been channeled to bolster the education of Lahu children in Thailand and to aid impoverished cancer patients.
With more than 30,000 native plant species, including thousands found nowhere else on Earth, China is known for its abundant flora. New species are frequently discovered in the country due to its size and variety of ecosystems.
These five new species with distinct flowers were recently published in Pensoft’s open-access journal PhytoKeys.
Belonging to the daisy family (Asteraceae), Melanoseris penghuana was observed growing on steep grassy slopes along the valley edge of Jiulonggou, Mt. Jiaozi Xueshan, at an elevation of approximately 3,200 m.
Through data analysis from two field surveys, the conservation status of this species was classified as Vulnerable. However, located within the Jiaozi Xueshan National Nature Reserve where human disturbance is minimal, its habitat is relatively well protected.
Hydrangea xinfeniae belongs to the family Hydrangeaceae and was discovered in the Huagaoxi National Nature Reserve in Shuiwei Town, Sichuan Province. It grows on moist soils under the broadleaved forest at an elevation of 1,200–1,300 m.
Currently known from only three relatively small populations of the type locality, its conservation status is assessed as Data Deficient.
This new species of cherry blossom belongs to the rose family (Rosaceae). It is currently known only from Wuyishan National Park, Fujian and Jiangxi Province, where it grows in various habitats such as the margins of evergreen broad-leaved forests, valleys, or roadsides, at an altitude of 600–1,000 m.
Belonging to the madder family (Rubiaceae), Ophiorrhiza reflexa grows in moist areas under evergreen broad-leaved forests in the limestone region of Napo County, Guangxi.
Researchers found three populations of the species with more than 1,000 individuals at each site during field investigations. The three sites all belong to Laohutiao Provincial Nature Reserve, which is well-protected and not under threat. Ophiorrhiza reflexa is preliminarily assessed as Least Concern.
Ligularia lushuiensis belongs to the daisy family (Asteraceae). It is currently known only from its type locality, Lushui, northwestern Yunnan, where it grows in alpine meadows at an elevation of 3,322 m.
Currently known only from a small population at its type locality, the single population researchers discovered consists of no more than 200 mature individuals. Overgrazing may threaten the habitat of this species, and it has been preliminarily categorised as Critically Endangered.
There are about 25,000 islands in the Pacific Ocean. The most remote of them are in North and East Polynesia, the Hawaiian Islands, and French Polynesia. Biologists have been attracted to these regions since the 18th century, but French Polynesia has received much less attention compared to the Hawaiian Islands.

Contributions to our knowledge of the pseudoscorpions of French Polynesia date from the 1930s and are associated with the Pacific Entomological Survey. Since then, the French Polynesian pseudoscorpion fauna has consisted of only four known species.
A female individual of Olpium caputi.
Thanks to international cooperation, a team of enthusiastic scientists has published the first discovery of a new species of pseudoscorpion from French Polynesia. Between 2017 and 2020, they studied French Polynesia’s fauna and environment for the French Polynesian Agricultural Service and as a part of a large-scale survey of arthropods. During their research work, they collected a few pseudoscorpion specimens on Huahine and Tahiti in the Society Islands.
Among them is a new species named Olpium caputi, collected by sieving moss at 1,450 m about sea level on the Mont Marau Summit, Tahiti, one of the Society Islands archipelago. Its scientific name honours Zuzana Čaputová, the President of Slovakia.
“As a female leader, she takes a strong stance and supports women and scientists. Even in the 21st century, women in science or top positions are rare. The rarity of the research in French Polynesia, the uniqueness of the discovery, and the fact that the new species is a female, led us to name it after this inspiring woman who can be a role model of courage and perseverance for many women,” says Jana Christophoryová, who led the study.
The paper is published in the open-access, peer-reviewed journal ZooKeys.
The team:
Katarína Krajčovičová of Bratislavské regionálne ochranárske združenie – BROZ, Bratislava, and Jana Christophoryová of Comenius University, Bratislava, are both zoologists, who specialize in the taxonomy, distribution, and ecology of pseudoscorpions. Frédéric Jacq, botanist, and Thibault Ramage, entomologist, are independent naturalists who have been working on improving the faunistic and taxonomic knowledge of French Polynesia for over 15 years.

A group of scientists led by researchers of Khamai Foundation discovered five dazzling new species of eyelash vipers in the jungles and cloud forests of Colombia and Ecuador. This groundbreaking discovery was made official in a study published in the open-access journal Evolutionary Systematics.
Prior to this research, the captivating new vipers, now recognized as among the most alluring ever found, were mistakenly classified as part of a single, highly variable species spanning from Mexico to northwestern Peru. The decade-long study initiated with an unexpected incident wherein one of the authors was bitten by one of these previously undiscovered species.

Eyelash vipers stand out due to a distinctive feature: a set of enlarged spine-like scales positioned atop their eyes. These “lashes” bestow upon the snakes a formidable and fierce appearance, yet the true purpose of this feature remains unknown. What is definite, however, is that certain populations exhibit longer, and more stylized eyelashes compared to others. The variations in the condition of the eyelashes led researchers to hypothesize the existence of undiscovered species.
The clue that led the researchers to suspect that there were new species of eyelash vipers was the fact that some populations in the cloud forests of Ecuador had almost no “lashes.” Photos by Lucas Bustamante and Jose Vieira.
Eyelash vipers are also famous for another feature: they are polychromatic. The same patch of rainforest may contain individuals of the turquoise morph, the moss morph, or the gold morph, all belonging to the same species despite having an entirely different attire. “No two individuals have the same coloration, even those belonging to the same litter (yes, they give birth to live young),” says Alejandro Arteaga, who led the study.
For some of the species, there is a “Christmas” morph, a ghost morph, and even a purple morph, with the different varieties sometimes coexisting and breeding with one another. The reason behind these incredible color variations is still unknown, but probably enables the vipers to occupy a wide range of ambush perches, from mossy branches to bright yellow heliconias.

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

What’s with the venom?
“The venom of some (perhaps all?) of the new species of vipers is considerably less lethal and hemorrhagic than that of the typical Central American Eyelash-Viper,” says Lucas Bustamante, a co-author of the study. Lucas was bitten in the finger by the Rahim’s Eyelash-Pitviper while taking its pictures during a research expedition in 2013. “I experienced intermittent local pain, dizziness and swelling, but recovered shortly after receiving three doses of antivenom in less than two hours after the bite, with no scar left behind,” says Bustamante.
Researcher Alejandro Arteaga examines the fangs of Central American Eyelash-Pitviper (Bothriechis nigroadspersus) in the Darién jungle of Panamá.
How threatened are these new species?
One of the study’s key conclusions is that four of the species in the group are facing a high risk of extinction. They have an extremely limited geographic range and 50% to 80% of their habitat has already been destroyed. Therefore, a rapid-response action to save the remaining habitat is urgently needed.

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

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

A new species of shark, which lived shortly after the mass extinction of the dinosaurs, was discovered when palaeontologist Jun Ebersole came across a 100-year-old box of teeth at the Geological Survey in Alabama, USA.
“Having documented hundreds of fossil fish species over the last decade, I found it puzzling that these teeth were from a shark that I didn’t recognise,” says Ebersole, Director of Collections, McWane Science Center, Birmingham, AL, who quickly realised the teeth belong to a new species.
The shark is a new species of Palaeohypotodus (pronounced pale-ee-oh-hype-oh-toe-duss), which means “ancient small-eared tooth,” in reference to the small needle-like fangs present on the sides of the teeth. Scientists believe it may have looked like a modern sand tiger shark.

Living approximately 65-million-years ago in the Paleocene era, Palaeohypotodus bizzocoi was likely a leading predator as the oceans recovered following the death of the dinosaurs, when more than 75% of life on Earth went extinct.
In Alabama, much of the southern half of the state was covered by a shallow tropical to sub-tropical ocean during the Paleocene.

“This time period is understudied, which makes the discovery of this new shark species that much more significant,” Harrell says. “Shark discoveries like this one give us tremendous insights into how ocean life recovers after major extinction events and also allows us to potentially forecast how global events, like climate change, affect marine life today.”
As part of their study of this ancient fish, the team compared the fossil teeth to those of various living sharks, like Great Whites and Makos. According to Cicimurri, shark teeth differ in shape depending on where they are located in the mouth.
“By studying the jaws and teeth of living sharks, it allowed us to reconstruct the dentition of this ancient species and showed that it had a tooth arrangement that differed from any living shark,” Cicimurri says.

The new species has been named Palaeohypotodus bizzocoi for the late Dr. Bruce Bizzoco (1949-2022) of Birmingham, AL. Bizzoco served as a Dean at Shelton State Community College, archaeologist, and was a long-time volunteer at McWane Science Center.
This discovery is part of an ongoing project led by Ebersole and Cicimurri to document Alabama’s fossil fishes. Together, they have confirmed over 400 unique species of fossil sharks and bony fishes, which, according to Ebersole, makes Alabama one of the richest places in the world in terms of fossil fish diversity.

Researchers have discovered two new freshwater hyphomycete (mould) species, Acrogenospora alangii and Conioscypha yunnanensis, in southwestern China.
This discovery, detailed in a study published in MycoKeys, marks the addition of these species to the Acrogenospora and Conioscypha genera, further enriching the diversity of freshwater fungi known in the region.
A research team consisting of Lu Li, Hong-Zhi Du and Ratchadawan Cheewangkoon from Chiang Mai University, Thailand, as well as Vinodhini Thiyagaraja and Rungtiwa Phookamsak from Kunming Institute of Botany, China, and Darbhe Jayarama Bhat from King Saud University, Saudi Arabia, employed comprehensive morphological analysis and multi-gene phylogenetic assessments in their study.
Notably, Acrogenospora alangii was identified on submerged branches of the medicinal plant Alangium chinense, highlighting a unique ecological association.

Freshwater fungi are highly diverse in China and frequently reported from submerged wood, freshwater insects, herbaceous substrates, sediments, leaves, foams, and living plants.
Most species are well-known as saprobes (organisms that live on decaying organisms) and they play an important role in ecological functioning as decomposers, but also can be pathogens as well as symbionts on humans and plants.
This research underscores the ecological and taxonomic richness of freshwater fungi in China, a country already recognised for its diverse fungal habitats. The findings contribute valuable insights into the roles these organisms play in freshwater ecosystems and emphasise the importance of ongoing biodiversity studies in these environments.

Zoosystematics and Evolution kicked off the year with research papers introducing 12 exciting new species from around the world. The journal, published by Pensoft on behalf of Museum für Naturkunde, is known for being at the forefront of animal research and, in particular, for sharing exciting new discoveries like those below.
Four jumping spiders from India
Four new species of Phintella were discovered in India. Generally striking in appearance, the genus now has 18 recognised species in India – second only to China.
Pleurobranchaea britannica, a newly discovered sea slug, is the first of its genus found in British waters. The unusual translucent creature also represents the second valid Pleurobranchaea species from European seas.
In the Tenasserim Mountain Range of western Thailand, researchers discovered Bungarus sagittatus, a new species of venomous elapid snake. The name sagittatus is derived from sagittata meaning arrow, referencing the dark triangular shape on its subcaudal scales which resembles a barbed arrow.
Researchers described two new species, Ariosoma gracile and Ariosoma kannani, from Indian waters, based on the materials collected from the Kochi coast, Gulf of Mannar and the West Bengal coast, along the Bay of Bengal.
Xanthomelon amurndamilumila was discovered on the North East Isles, offshore from Groote Eylandt, Australia. Its conservation status is of concern on North East Island because of habitat degradation caused by feral deer.
A new Eurasian minnow, Phoxinus radeki, was discovered in the Ergene River (Aegean Sea Basin). Salmo brunoi, a new species of trout, was discovered in the Nilüfer River, a tributary of the Susurluk River.
Ditha shivanparaensis may look like a scorpion, but looks can be deceiving. Rather, it is an arachnid, newly discovered from the tropical montane cloud forests or ‘sholas’ of the Western Ghats of India.
