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). Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 332–333, provided a brief account, photograph, and range map. Kanga, Kouamé, Zogbass, Gongomin, Agoh, Kouamé, Konan, Adepo-Gourène, Gourène, and Rödel, 2021, Amph. Rept. Conserv., 15: 71–107, commented on conservation status, systematics, identification, range, and habitat on the Ivory Coast side of Mont Nimba.
