Confirmation of the distribution of Gonyosoma prasinum (Blyth, 1855) and Boiga multomaculata septentrionalis Köhler, Charunrochana, Mogk, Than, Kurniawan, Kadafi, Das, Tillack & O’Shea, 2023 (Serpentes, Colubridae) in China

Gonyosoma prasinum (Blyth, 1855) was once considered a widely distributed species. Later, it was revealed that it is a species complex and has been divided into three species. Presently, Gonyosoma prasinum (Blyth, 1855) is known to be only distributed in India, Myanmar and Bhutan and there is no confirmed record of its occurrence in China. Boiga multomaculata septentrionalis Köhler, Charunrochana, Mogk, Than, Kurniawan, Kadafi, Das, Tillack & O’Shea, 2023 is a subspecies of B. multomaculata described from Kachin State, Myanmar. It is known to be distributed in Myanmar and India and is speculated to be also distributed in China. Recently, two snake specimens were collected from Yingjiang County, Dehong Prefecture, Yunnan Province, China. Based on morphological comparison and phylogenetic analysis, we determine that the two specimens belong to Gonyosoma prasinum and Boiga multomaculata septentrionalis , respectively. Therefore, we confirm the distribution of these two species in China.
