Comment

The west African population, formerly known as Sclerophrys superciliaris chevalieri is not recognized as a distinct species. See account in Perret, 1966, Zool. Jahrb., Jena, Abt. Syst., 93: 312-313 (in the sense of including what is now Sclerophrys channingi). In the Bufo superciliaris group of Martin, 1972, in Blair (ed.), Evol. Genus Bufo: 62, and Tandy and Keith, 1972, in Blair (ed.), Evol. Genus Bufo: 160. Gabon records by Lötters, Gossmann, Obame, and Böhme, 2001, Herpetofauna, Weinstadt, 23: 22, and Frétey and Blanc, 2002 "2001", Bull. Soc. Zool. France, 126: 380, reported this species from Gabon. See brief comments by Rödel, Bangoura, and Böhme, 2004, Herpetozoa, Wien, 17: 108, regarding range and natural history. Schiøtz, 1963, Vidensk. Medd. Dansk Naturhist. Foren., 125: 22, provided records for Nigeria. Barej, Schmitz, Menegon, Hillers, Hinkel, Böhme, and Rödel, 2011, Zootaxa, 2772: 1-32, provided the most recent revision, recognizing the eastern Dem. Rep. Congo population as Amietophrynus channingi, and the populations in the eastern and western Guinean forest blocks as, respectively, Amietophrynus superciliaris chevalieri and Amietophrynus superciliaris superciliaris.  Jongsma, Tobi, Dixon-MacCallum, Bamba-Kaya, Yoga, Mbega, Mve Beh, Emrich, and Blackburn, 2017, Amph. Rept. Conserv., 11 (1: e144): 8–9, provided a record for southeastern Gabon and briefly discussed habitat and range. Dewynter and Frétey, 2019, Cah. Fondation Biotope, 27 : 18, summarized the literature for Gabon and provided photographs (p. 53). Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 74–75, 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. California Acad. Sci., Ser. 4, 66: 137–230. Ernst, Lautenschläger, Branquima, and Hölting, 2020, Zoosyst. Evol., 96: 251, noted the species to occur in Uigé Province of northwestern Angola, and suggested that revisionary work is warranted.
