NEW RECORDS OF SNAKES (Reptilia: Squamata: Serpentes) FROM SON LA PROVINCE
PHAM VAN ANH, NGUYEN THI BICH NGOC, NGUYEN THI MEN, NGUYEN LAN HUNG SON, NGUYEN QUANG TRUONG
SUMMARY
Based on recently herpetological collection from Copia and Sop Cop nature reserves, we herein report six new records of snakes from Son La province, comprising five species of the family Colubndae {Pararhabdophis chapaensis. Amphisma khasiensis, Dendrelaphis pictus. Pareas hamptoni, Pareas maculanus) and one species ofthe family Viperidae (Ovophis monticola). Pararhabdophis chapaensis. a poorly known and an endemic species of Vietnam, was rediscovered after 80 years since Bourret's (1934) description based on a single specimen from Sa Pa. Lao Cai province. Our results bring the species number of snakes to 44 belonging to 30 genus and 6 families in Son La province. In addition, we provide further morphological and natural history data of afore mentioned species
