Ptychadena stenocephala (Boulenger, 1901)

Narrow-headed Grass Frog

Material: Two females, NGK-Nimba 0030, NGK-Nimba 0100 (Fig. 14B).

Comments: Two females of the Ptychadena stenocephala -complex (Rödel and Channing 2019) have been found at the edge of a roadside puddle near a heavily degraded forest in the Yéalé village (07°31.928’N, 008°25.401’W; 425 m asl). While they superficially resemble P. mascareniensis, e.g., by the ridges and a similar vertebral band (see e.g., Rödel and Glos 2019), they differ from the latter species by reduced webbing, and much more slender body shape (Channing and Rödel 2019). The exact taxonomic status of these frogs requires further research.
