New records of megophryids (Amphibia: Anura: Megophryidae) from Son La Province, Vietnam

Abstract. BACKGROUND: The family Megophryidae is one of the most poorly known groups of amphibians in Son La Province, Vietnam. In the herpetofaunal list of Vietnam in 2009 only two species of megophryids were recorded from this province and recent studies have documented five additional species of Megophryidae from Son La Province. NEW INFORMATION: Based on recent field work in northern Vietnam, we report six new provincial records of the family Megophryidae from Son La Province, namely Leptobrachium ailaonicum, Leptobrachella sungi, Megophrys feae, M. jingdongensis, M. microstoma and M. parva. In addition, morphological data were provided for each species, based on newly collected specimens. Our findings bring the species number of the family Megophryidae to 13 in Son La Province.
