Nianyu, Shangchuan Island, Taishan City, Guangdong Province of China. The diagnostic characters of O. laui are revised accordingly as follows: dorsal scales moderately keeled throughout, in 23(25):23:21(23) rows; 10 supralabials; 9-11 infralabials; two internasals, longer than wide, not touching with the loreal; one loreal, not touching with the eye; one or two preoculars; two postoculars; one or two posterior temporal scales; 170-176 ventrals in males, 152-159 ventrals in females; 58-61 pairs of subcaudals in males, 53-61 in females; body and tail dark olive above, with light yellow cross bars.展开更多

The new specimens are consistent with the type series in scale counts and body dimensions. However, two individuals lack yellow cross-bands that are apparent in the type specimens. A key to the ten Chinese species of Opisthotropis is provided.展开更多
