Comment

In the Astylosternus diadematus group of Amiet, 1978 "1977", Ann. Fac. Sci. Cameroun, 23–24: 99–227. Removed from the synonymy of Astylosternus diadematus by Amiet, 1978 "1977", Ann. Fac. Sci. Cameroun, 23–24: 99, where it had been placed by Parker, 1936, Proc. Zool. Soc. London, 1936: 135–166. Deckert, 1938, Sitzungsber. Ges. Naturforsch. Freunde Berlin, 1938: 150, recognized this species without comment on Parker's earlier action. Gabon record provided by Lötters, Gossmann, Obame, and Böhme, 2001, Herpetofauna, Weinstadt, 23: 23. 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: 89–90, reported on comparative tadpole morphology. Jongsma, Tobi, Dixon-MacCallum, Bamba-Kaya, Yoga, Mbega, Mve Beh, Emrich, and Blackburn, 2017, Amph. Rept. Conserv., 11 (1: e144): 6, provided a record for southeastern Gabon and briefly discussed habitat and range. Griesbaum, Hirschfeld, Barej, Schmitz, Rohrmoser, Dahmen, Mühlberger, Liedtke, Gonwouo, Doumbia, and Rödel, 2019, Zoosyst. Evol., 95: 133–160, redescribed larval morphology. Larson and Zimkus, 2018, Herpetol. Conserv. Biol., 13: 244–245, briefly discussed the populations in Gabon. Deichmann, Mulcahy, Vanthomme, Tobi, Wynn, Zimkus, and McDiarmid, 2017, PLoS One, 12 (11: e0187283): 14, provided molecular evidence for Astylosternus batesi being a species complex or that identifications need to be verified. Dewynter, Chirio, Melki, Cordier, and Frétey, 2017, Cah. Fondation Biotope, 11: 9, provided a brief account and photographs of this species from the Mount Koumouna-Bouali area of Gabon. Dewynter and Frétey, 2019, Cah. Fondation Biotope, 27: 10, summarized the literature for Gabon and provided photographs (p. 46). Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 232–233, provided a brief account, photograph, and range map. See brief account, range map, and photographs for Equatorial Guinea in Sánchez-Vialas, Calvo-Revuelta, Castroviejo-Fisher, and De la Riva, 2020, Proc.
