Comment

The species figured as Astylosternus corrugatus by Perret, 1966, Zool. Jahrb., Jena, Abt. Syst., 93: 378-379, is Astylosternus perreti; see Amiet, 1973, Ann. Fac. Sci. Cameroun, 13: 140. Lasso, Rial, Castroviejo, and De la Riva, 2002, Graellsia, 58: 21-34, provided notes on ecological distribution in Equatorial Guinea. Channing, Rödel, and Channing, 2012, Tadpoles of Africa: 123–125, reported on comparative tadpole morphology. Neil and Jongsma, 2017 "2016", Herpetol. Rev., 47: 623–624, provided a record for Estuaire Province, Gabon. Dewynter, Chirio, Melki, Cordier, and Frétey, 2017, Cah. Fondation Biotope, 11: 19, provided a brief account and photographs of this species from the Mount Koumouna-Bouali area of Gabon. Griesbaum, Hirschfeld, Barej, Schmitz, Rohrmoser, Dahmen, Mühlberger, Liedtke, Gonwouo, Doumbia, and Rödel, 2019, Zoosyst. Evol., 95: 133–160, redescribed larval morphology. Dewynter and Frétey, 2019, Cah. Fondation Biotope, 27: 11, summarized the literature for Gabon and provided photographs (p. 46). See brief account, range map, and photographs for Equatorial Guinea in Sánchez-Vialas, Calvo-Revuelta, Castroviejo-Fisher, and De la Riva, 2020, Proc. California Acad. Sci., Ser. 4, 66: 137–230.
