[1][3] It is only known from Labé—the type locality which could refer to several places in Guinea—and from Beyla, Guinea and Tingi Hills, Sierra Leone.

[1][3] Hampton Wildman Parker named this species in honour of Fernand Angel, a French zoologist and herpetologist from the National Museum of Natural History.

[2][4] Angel helped Parker to get access to specimens at the National Museum of Natural History that were included as paratypes in the species description.

The snout is rounded and prominent, with nostrils close to its tip.

Geotrypetes seraphini is known to be viviparous and not to dependent on water for breeding, and this might well apply to this species too.
