New records of amphibians from Bac Kan Province, Vietnam

Since the establishment of the Nam Xuan Lac Habitat and Species Conservation Area in 2003 in Bac Kan Province, northern Vietnam, only two herpetological studies have been conducted: One recorded 14 species of amphibians from Ban Thi-Xuan Lac area in 2004 and a recent study reported 32 species of amphibians from this protected area in 2019. As a result of our field surveys in 2020 and 2021, a total of 23 species of amphibians was recorded from the Nam Xuan Lac Habitat and Species Conservation Area. Eight of them are recorded for the first time from Bac Kan Province, comprising one species of Microhylidae, two species of Megophryidae, one species of Dicroglossidae, two species of Ranidae and two species of Rhacophoridae. Besides morphological descriptions, we provide ecological notes of newly-recorded species of amphibians from Bac Kan Province.
