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.
