Note: These species pages are in various stages of completion. Some are basically finished; others are very much under construction. Please be patient while I work on this section.

Godman’s Garter Snake previously included the garter snake populations now known as Bogert’s Garter Snake, Thamnophis bogerti, Conant’s Garter Snake, Thamnophis conanti, and Liner’s Garter Snake, Thamnophis lineri. Rossman and Burbrink’s 2005 paper created those three new species on the grounds that each population formerly belonging to T. godmani was morphologically distinct and geographically isolated from the others.

Thamnophis godmani has been retained for populations from Guerrero, where it has been found in pine-oak and cloud forest in the Sierra Madre del Sur.

Very little is known about the four species in this complex.

If you have experience with this species and would like to share, please contact me.
