A global team of scientists has identified and named a new species of leaf-tailed gecko from northern Madagascar - Uroplatus garamaso. Leaf-tailed geckos are masters of disguise. Some species have skin flaps all over the body and head, as well as flat tails. During the day, they lie head down on tree trunks, spreading their skin flaps and blending in with their surroundings, making themselves almost invisible. As night falls, they become active, weaving among the slender branches of the forest understory in search of invertebrate prey.

Dr. Frank Glaw, curator of reptiles at the Bavarian State Zoological Collection and first author of this study, said: "When we first discovered this species in 2000, we It was already suspected that it might be new to science. It took many years for us to accumulate enough information to confidently describe it as a new species. Image credit: Dr. Jörn Köhler, Hessian State Museum, Darmstadt, Germany
The research team collected data on the genetics, morphology and distribution of the species. They conducted multiple expeditions to northern Madagascar, expanding their knowledge of this new species. The findings were recently published in the open-access scientific journal Salamandra.

One of the challenges in the research work was that Uroplatus garamaso is very similar to another species, Uroplatushenkeli, and has been confused with it in the past. Dr. Jörn Köhler from the Hessian State Museum in Darmstadt explains: "This is very common among reptiles in Madagascar. There are many of these so-called 'cryptospecies' awaiting classification."

Through careful analysis, the author discovered some distinguishing characteristics of these two types of geckos. Dr. Philip-Sebastian Gehring from the University of Bielefeld in Germany said: "The real key is that we found that the tip of the tongue of U. henkeli is black, while the tip of the tongue of U. garamaso is pink. The new species has a body length of 20 cm, which is slightly smaller than U. henkeli and has a narrower tail." TAGPH 28
Dr. Fanomezana Ratsoavina of the University of Antananarivo in Madagascar, who studied leaf-tailed geckos, said: "This new species is the latest in a series of new Uroplatus geckos described in Madagascar over the past few years."

Dr. Mark Scherz, Curator of Reptiles at the Natural History Museum of Denmark, said: "We are close to completing the taxonomic catalog of this genus, but this is just the beginning of our understanding of its evolution and ecology. The color of the bill is very useful in identifying different species, but its function is completely unknown. There is still a lot we don't know about these geckos, from their wider evolutionary relationships to their behavior."
