Indonesian ratsnake (Coelognathus subradiatus) in Baucau District, East Timor.

Coelognathus is a genus of five ratsnakes that were formerly assigned to the genus Elaphe. Based on morphological evidence and protein similarities, in 2001 Helfenberger re-validated the name Coelognathus that had originally been proposed by Leopold Fitzinger in 1843.[1] The distinction between Coelognathus and Elaphe was further supported by mitochondrial DNA sequence and additional morphological evidence in 2005.[2]
