Redescription of Rhacophorus chuyangsinensis Orlov, Nguyen & Ho, 2008 (Anura: Rhacophoridae) based on new collections from new south Vietnamese provincial records: Lam Dong and Khanh Hoa. -Rhacophorus chuyangsinensis Orlov, Nguyen, & Ho, 2008, which was de-scribed based on a type series consisting of three adult males only, is re-described based on extensive new collections from southern Vietnam. Our new records consist of 17 individuals, among them the first two females to become known. In our extended description we deal for the first time with adult female morphology and with so far unknown colour pattern in life. Our new records of R. chuyangsinensis for Lam Dong and Khanh Hoa provinces expand the originally known distribution of this species about 81 km to the Southeast of its type locality (Chu Yang Sin National Park, Dak Lak Province, southern Vietnam, 1,600 m a.s .1.). We further add additional information on the natural history of R. chuyangsinensis, which inhabits rocky forest streams at altitudes between 1,320-1,600 m a.s.l.
