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]
Species
The following species are recognized as being valid:[3]
- Coelognathus enganensis (Vinciguerra, 1892)
- Coelognathus erythrurus (A.M.C. Duméril, Bibron & A.H.A. Duméril, 1854) – Philippine rat snake
- Coelognathus flavolineatus (Schlegel, 1837) – yellow-striped ratsnake
- Coelognathus helena (Daudin, 1803) – trinket snake
- Coelognathus radiata (F. Boie, 1827) – copperhead ratsnake
- Coelognathus subradiatus (Schlegel, 1837) - Indonesian ratsnake
Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Coelognathus.
