A New Species of the Genus Rhacophorus (Anura: Rhacophoridae) from Southern China

A new species of rhacophorid of the genus Rhacophorus is described from the Shiwandashan National Nature Reserve, Guangxi, Southern China. Rhacophorus pinglongensii sp. nov. is compared with congeners from China and other parts of Southeast Asia. The new species is distinguished from its congeners by combination of following characters: (1) small size (adult male, SVL 32.0-38.5 mm); (2) smooth and green dorsum; (3) flanks, axilla, ventral surface of forearms, inguinal, anterior and posterior surfaces of thighs, ventral surface of shank, and dorsal surface of feet covered with black blotches with white spots or white spots with a faint orange tint; (4) ventral surface of feet and webbing tangerine; (5) supratympanic fold weak; (6) outer margin of forearms and feet with low dermal ridges; (7) calcars absent on heels; (8) iris silver, diffusing to ecru laterally with light khaki ring along margin. The new species is closely related to R. dorsoviridis, R. moltrechti, and R. nigropunctatus based on adult morphology. Currently, this species is known only from mid-elevation montane evergreen forest in the Shiwandashan National Nature Reserve, Guangxi, China.
