This species ranges from western and southern Cameroon (where it avoids the coastal plain) south through Gabon and Congo to the Cabinda Enclave of Angola, and western Democratic Republic of Congo. In Cameroon it occurs at 500-800 m, but it occurs close to sea-level in Congo. The western limits of its distribution are unknown, and the boundary between this species and Hyperolius nasutus in Angola and the Democratic Republic of Congo are also unknown. It presumably occurs in Equatorial Guinea, and the species' distribution on the map includes this area, but there do not appear to be any records from this country yet.
Habitat and Ecology
It is a species of open secondary habitats in the forest zone that does not occur in closed-canopy forest. It breeds in marshes and pools (often human-made). It is able to colonize open habitats inside undisturbed forest, presumably travelling through unsuitable habitat to do so.
There is little information, but it appears to be a common species.
No threats are known, and it is presumably increasing with forest clearance.
It presumably occurs in some protected areas.
This species was removed from synonymy of Hyerolius nasutus (or Hyperolius acuticeps sensu Channing et al. (2002)) by Amiet (2005).
