‘Leaf-toed' creature found ‘wandering' at night in Cambodia. It's a new species
Nearby scientists noticed the spotted animal — and discovered a new species.
A team of researchers visited some poorly known karstic rock formations in Battambang Province in March 2024 to survey reptiles and amphibians. Karstic habitats generally have high levels of biodiversity so the team expected to find some interesting animals, according to a study published June 30 in the peer-reviewed journal Zootaxa.
During their visit, researchers encountered over a dozen unfamiliar-looking geckos, the study said. Intrigued, they took a closer look at the lizards, analyzed their DNA and quickly realized they'd discovered a new species: Dixonius noctivagus, or the Battambang leaf-toed gecko.
Battambang leaf-toed geckos are considered 'small,' reaching just over 4 inches in length, the study said. They have 'flat' snouts and 'moderate'-sized eyes with a 'reddish'-gold mosaic-like pattern. Its 'short' fingers and toes have 'expanded,' 'leaf'-like pads.
Photos show the new species' coloring. Overall, its body is light brown with darker brown blotches almost resembling leopard spots.
Battambang leaf-toed geckos were found on karstic boulders, 'a cement wall' and on the ground nearby, the study said. Several female geckos were found pregnant with 'two eggs, indicating that breeding probably occurs in February and March.'
Researchers said they named the new species after the Latin words for 'night' and 'vagrant or wandering' because of its 'nocturnal activity.'
The new species' common name refers to the site in Battambang Province where it was first discovered and, so far, the only place where it has been found. The range of these geckos 'undoubtedly extends farther in all directions,' researchers said.
Battambang Province is in western Cambodia and along the border with Thailand. Cambodia also borders Laos and Vietnam.
The new species was identified by its scale pattern, coloring, pores and other subtle physical features, the study said. DNA analysis found the new species had at least 7% genetic divergence from other related geckos.
The research team included L. Lee Grismer, Pablo Sinovas, Evan Quah, Sothearen Thi, Phyroum Chourn, Sophea Chhin, Seiha Hun, Anthony Cobos, Christian Ching, Matthew Murdoch, Jeren Gregory, Eddie Nguyen, Alex Hernandez, Amanda Kaatz and Jesse Grismer.
The team also discovered two more new species of gecko in the same rocky habitat: the Kamping Poi bent-toed gecko and Khpoh slender gecko.
'Small and cryptic species like these newly described geckos often escape notice,' study co-author Sinovas said in a June 30 news release from Flora & Fauna. 'Bringing them to light is just the beginning of an exciting journey, one we hope will lead to the protection of these remarkable karst landscapes.'
'Cambodia's karst landscapes remain largely uncharted, their vast biodiversity still underreported, yet they face increasing pressure from human activities — from tourism development to industrial-scale destruction caused by mining for building materials,' Sinovas said in the release. 'We must prioritise the protection of these fragile karst ecosystems before rare species are lost forever.'

‘Leaf-toed' creature found ‘wandering' at night in Cambodia. It's a new species
Night stretched across western Cambodia, coaxing a 'leaf-toed' creature from its hiding place and onto the boulders. Its 'reddish'-gold eyes scanned the surrounding landscape, but it wasn't the only one searching. Nearby scientists noticed the spotted animal — and discovered a new species.

In Berlin's new zoo of sorts, you watch archaeologists, not animals
What was life in Berlin like centuries ago? And what traces did people leave behind? Visitors can watch these questions being answered in real time at Germany's new zoo-like lab where you can watch archaeologists at work behind glass. Petri Berlin is designed as a workshop and laboratory building, aiming to give visitors insights into the work of archaeologists. Through large windows, visitors can observe them at work on various floors. "Here, visitors can trace the journey of a find — from excavation, through cleaning, restoration and cataloguing, to its display as an exhibit," said director Anne Sklebitz at a press conference launching the Petri Berlin exhibition. The detective work behind the research often remains hidden, but can now be seen as it happens, the archaeologist said. "Petri Berlin is not a museum, but a workshop and laboratory building that offers visitors insights into the work of archaeologists," commented state archaeologist Matthias Wemhoff. The seven-storey building is divided thematically: Finds are cleaned on the first floor and restored on the second. There are also interactive stations where visitors can get hands-on experience. A highlight of the new centre is the remains of a medieval Latin school from the 14th century. The entire archaeology lab was built on the foundations of this school. In the basement, visitors can admire parts of the walls. The school stood on central Berlin's Petriplatz, one of the oldest parts of the city and the site of the former Petri Church, then centre of the city of Cölln, one of the two nuclei of Berlin. Foundation remains of the church are also on display in the exhibition. Initially, the museum is officially only German-language, but tours and workshops are on offer and most Berlin museum workers can easily switch into English.

This bright nova is making a rare appearance. How to glimpse it in Michigan
If you thought you saw a new star in Michigan's night sky recently, you may have glimpsed V462 Lupi, a rare nova in the Lupus constellation. The stellar explosion from one of Lupus' dim stars took on a very bright appearance, first spotted by astronomers in mid-June, according to Though viewing was strongest in the southern hemisphere, the Lake Superior area in northern Michigan observed the rare celestial object, per Sky & Telescope. Here's what to know. A nova is a stellar explosion in a binary system of two stars orbiting each other, per NASA. This classical nova formed from a dim star in the Lupus constellation, according to Astronomers at Ohio State University first observed the bright object on June 12, per Live Science. An astronomer at the University of Cape Town in South Africa then identified it as a classical nova on June 16. This constellation, Latin for wolf, can be found in the southern hemisphere in the night sky, according to Constellation Guide. Lupus is between Centaurus and Scorpius. Nova V462 Lupi has been observed around Lake Superior, per Sky & Telescope.
