Species removed from the genus The genus ''Opheodrys'' at one time included two Asian species: ''O. herminae'', which is endemic to Japan, and ''O. major'', which is endemic to Central/South China, Taiwan, N.

The European colubrid called grass snake (''Natrix natrix'') is not closely related. The rough green snake is docile, often allowing close approach by humans, and rarely bites. Even when bites occur, they have no venom and are harmless. Description The rough green snake (''Opheodrys aestivus'') is bright green above and has a yellowish belly, affording it excellent camouflage in green vegetation and making them difficult to see in the wild even though they are relatively common in their habitat. It has keeled dorsal scales, which are arranged in 17 rows at mid-body. It grows up to in total length (including tail) and is very thin.
