See comment under Phlyctimantis verrucosus. Reviewed by Perret, 1986, Bull. Soc. Neuchatel. Sci. Nat., 109: 19–26. Laurent, 1976, Ann. Mus. R. Afr. Cent., Tervuren, Ser. Octavo, Sci. Zool., 213: 21–23, provided and account. De la Riva, 1994, Rev. Esp. Herpetol., 8: 130, provided a record for Equatorial Guinea. Frétey and Blanc, 2002 "2001", Bull. Soc. Zool. France, 126: 383, reported this species from Gabon. See comment under Phlyctimantis boulengeri. Lasso, Rial, Castroviejo, and De la Riva, 2002, Graellsia, 58: 21–34, provided notes on ecological distribution in Equatorial Guinea. Gvoždík and Kopecký, 2012, Herpetol. Rev., 43: 98, provided a record for Cameroon and commented on the range. See account for Cameroon by Amiet, 2012, Rainettes Cameroun: 424–431.. Schiøtz, 1999, Treefrogs Afr.: 319–320, provided a brief account and map. Jongsma, Tobi, Dixon-MacCallum, Bamba-Kaya, Yoga, Mbega, Mve Beh, Emrich, and Blackburn, 2017, Amph. Rept. Conserv., 11 (1: e144): 14, provided records for southeastern Gabon and briefly discussed habitat and range. Baptista, Conradie, Vaz Pinto, and Branch, 2019, In Huntley, Russo, Lages, and Ferrand (eds.), Biodiversity in Angola: 258, doubted that this species will be found in Angola. Dewynter and Frétey, 2019, Cah. Fondation Biotope, 27: 30, summarized the literature for Gabon and provided photographs (p. 59). As the ranges seem to be highly provisional, it seems that the ranges of and the boundary between and the populations within Phlyctimantis leonardi and Phlyctimantis boulengeri need to be assayed at a molecular basis to determine how many lineages and the ranges that compose both nominal species (DRF). Dewynter and Frétey, 2019, Cah. Fondation Biotope, 27: 30, summarized the literature for Gabon. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 132–133, provided a brief account, photograph, and range map. See brief account, range map, and photographs (as Phlyctimantis cf. leonardi) for Equatorial Guinea in Sánchez-Vialas, Calvo-Revuelta, Castroviejo-Fisher, and De la Riva, 2020, Proc. California Acad. Sci., Ser. 4, 66: 137–230, who suggested that the complex needs revision.
