(Holotype: CIB610623, adult male, SVL 59.6 mm) has been recognized based on the collections from Nanjiang County, Sichuan Province in China, which was previously recognized as O. schmackeri. This new species can be distinguished from the latter by the combination of the following characteristics: (1) the sexual dimorphism ratio is smaller in size between males and females of O. nanjiangensis; 1∶1.34 (male to female), males’ mean SVL 55.6 mm, females’ mean SVL 74.6 mm, compared to the ratio of males (mean SVL 44.6 mm) to females (mean SVL 80.0 mm) of O. schmackeri is 1∶1.93, (2) vomerine teeth have two short series in O. nanjiangensis, compared to two long series in O. schmackeri; (3) dark spots present on green body back and have no light edge on O. nanjiangensis, while light-edged compared to dark spots with light edge on O. schmackeri; (4) rear
