New records and an updated checklist of the herpetofauna from Tay Yen Tu Nature Reserve, north-eastern Vietnam

Since its establishment in 2002, several studies on the herpetofauna of this protected area have been carried out. For example, Nguyen et al. reported 25 species of snakes in 2002 and most recently, Hecht et al. reported 36 species of amphibians and 40 species of reptiles in the Nature Reserve in 2013.

Remarkably, two new species of amphibians and two new species of reptiles have been discovered from Tay Yen Tu Nature Reserve since 2005.As a result of our fieldwork in Tay Yen Tu Nature Reserve between 2015 and 2025, we recorded four species of amphibians and three species of reptiles for the first time from Bac Giang Province, comprising two species of Leptobrachella, one species of Kaloula, one species of Hylarana, one species of Takydromus, one species of Sinomicrurus and one species of Xenopeltis.
