Reviewed by Perret, 1979, Bull. Soc. Neuchatel. Sci. Nat., 102: 10, who noted that it had frequently been confused with Ptychadena bibroni (= Ptychadena mascareniensis). Perret, 1997, Bull. Soc. Neuchatel. Sci. Nat., 120: 77, noted that records from Mont Nimba, Guinea, probably referred to an undescribed species. Rödel, 2000, Herpetofauna W. Afr., 1: 136-138, provided an account and noted that the species is likely more widespread. See discussion by Lamotte and Ohler, 2000, Zoosystema, 22: 569-583. Channing and Howell, 2006, Amph. E. Afr.: 314-315, provided an account for East Africa (Uganda and Tanzania).
