New information 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.
