The colubrid snake Brygophis coulangesi (Domergue 1988) rediscovered in north-eastern Madagascar

A description and biological notes on the second known specimen of the opistoglyph colubrid snake Brygophis coulangesi (Domergue 1988) are provided together with a re-analysis of the holotype. The new specimen was collected in north-eastern Madagascar, from the Anjanaharibe-Sud Chain and it has a large range extension of about 500 km. It is similar in morphology and colouration to the holotype, found in 1968 at Fiherenana Forest, central-eastern Madagascar. Comments are also provided about the similarity of Brygophis with the genus Geodipsas.
