Comment

Gabon record provided by Lötters, Gossmann, Obame, and Böhme, 2001, Herpetofauna, Weinstadt, 23: 22. Rödel and Branch, 2002, Salamandra, 38: 236, reported a species, similar to Arthroleptis variabilis, but smaller, from Ivory Coast. Rödel and Bangoura, 2004, Tropical Zool., 17: 213, noted differences between Cameroon and West African populations that suggest that these represent different species. Lasso, Rial, Castroviejo, and De la Riva, 2002, Graellsia, 58: 21-34, provided notes on ecological distribution in Equatorial Guinea. Schiøtz, 1963, Vidensk. Medd. Dansk Naturhist. Foren., 125: 31, provided records for Nigeria. Frétey, 2008, Alytes, 25: 99-172, summarized the literature. Blackburn, Gonwouo, Ernst, and Rödel, 2009, Breviora, 515: 1-23, redescribed the species, compared it to relevant species, provided extensive citation to relevant literature, and noted that West Africa specimens (Ivory Coast, Ghana, Guinea, Liberia) correspond to various undescribed species. Rödel, Doumbia, Johnson, and Hillers, 2009, Zootaxa, 2302: 26, commented on records west of Nigeria being based on misidentifications. Larson and Zimkus, 2018, Herpetol. Conserv. Biol., 13: 244, briefly discussed the Gabon population. Dewynter and Frétey, 2019, Cah. Fondation Biotope, 27: 7, noted the literature for Gabon, provided photographs (p. 44) and noted that at least some specimens previously identified as this species from Gabon may actually be the more recently named Arthroleptis perretiChanning and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 266–267, provided a brief account, photograph, and range map. See brief account and photographs for Equatorial Guinea by Sánchez-Vialas, Calvo-Revuelta, Castroviejo-Fisher, and De la Riva, 2020, Proc. California Acad. Sci., Ser. 4, 66: 148. Kako-Wanzalire, Mongo, Ilonga, Mapoli, Mbumba, Neema, Tungaluna, Itoka, and Bogaert, 2021, Tropicultura, 39 (1: 1709): 1–19, briefly discussed habitat preference in north-central and northeastern Dem. Rep. Congo. See comment by Badjedjea, Masudi, Akaibe, and Gvoždík, 2022, Amph. Rept. Conserv., 16 (1: e301): 42–43, who noted a likely unnamed species in central Dem. Rep. Congo (as Arthroleptis sp. aff. variabilis).
