Comment

Discussed by Perret, 1979, Bull. Soc. Neuchatel. Sci. Nat., 102: 15, as subspecies of Ptychadena pumilio. Removed from the synonymy of Ptychadena pumilio by Poynton and Broadley, 1985, Ann. Natal Mus., 27: 153, who mentioned that Perret (in litt.) disputed the synonymy of of Ptychadena smithi Guibé, 1960. See also Poynton, 1964, Ann. Natal Mus., 17: 132. Account in Schmidt and Inger, 1959, Explor. Parc Natl. Upemba, Miss. G.F. de Witte, 56: 109-111. See also brief account by Lambiris, 1988, Lammergeyer, 39: 85-86. Rödel, 2000, Herpetofauna W. Afr., 1: 95, discussed briefly the issue of possible conspecificity of this species with Ptychadena pumilio. Records of Ptychadena pumilio in South Africa refer to Ptychadena taenioscelis. See accounts by Channing, 2001, Amph. Cent. S. Afr.: 341-342, Channing and Howell, 2006, Amph. E. Afr.: 315-316, Minter and Passmore, 2004, in Minter et al. (eds.), Atlas Frogs S. Afr. Lesotho and Swaziland: 294-296, Lötters, Wagner, Bwong, Schick, Malonza, Muchai, Wasonga, and Veith, 2007, Fieldguide Amph. Rept. Kakamega Forest: 25-26, and Du Preez and Carruthers, 2009, Compl. Guide Frogs S. Afr.: 324. Schiøtz, 1963, Vidensk. Medd. Dansk Naturhist. Foren., 125: 24, provided records for Nigeria. Lötters, Rotich, Koester, Kosuch, Muchai, Scheelke, Schick, Teege, Wasonga, and Veith, 2006, Salamandra, 42: 165 -179, provided a Kenyan locality. Pauwels and Rödel, 2007, Herpetozoa, Wien, 19: 135-148, tentatively regarded Ptychadena taenioscelis as synonymous with Ptychadena pumilio. Pickersgill, 2007, Frog Search: 147-150, provided an account and rejected any close relationship of Ptychadena taenioscelis and Ptychadena pumilio. Jacobsen, 2009, Afr. Herp News, 47: 2-20, reported this species from east-north-central Central African Republic. Bwong, Chira, Schick, Veith, and Lötters, 2009, Salamandra, 45: 129-146, discussed the assignment of a population in western Kenya to this taxon and outstanding questions regarding the systematics of this species. Mercurio, 2011, Amph. Malawi: 268-270, provided an account for Malawi. Harper, Measey, Patrick, Menegon, and Vonesh, 2010, Field Guide Amph. E. Arc Mts. Tanzania and Kenya: 270–271, provided a brief account and photograph. Ohler and Frétey, 2014, J. E. Afr. Nat. Hist., 103: 100–101, provided a brief discussion of a collection from northern Mozambique. Deichmann, Mulcahy, Vanthomme, Tobi, Wynn, Zimkus, and McDiarmid, 2017, PLoS One, 12 (11: e0187283): 22–23, discussed the possibility of this nominal species (in the sense of being a complex) in Gabon and Rep. Congo. Dewynter, Chirio, Melki, Cordier, and Frétey, 2017, Cah. Fondation Biotope, 11: 25, 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: 38, summarized the literature for Gabon, provided photographs (p. 64, as Ptychadena cf taenioscelis), and briefly summarized the taxonomic difficulties. Phaka, Netherlands, Kruger, and Du Preez, 2017, Bilingual Field Guide Frogs Zululand: 59, provided a photograph, Zululand regional map, and a brief account of life history and identification. See Bittencourt-Silva, 2019, Amph. Rept. Conserv., 13 (2: e181): 11, for comment on population likely of this species in western Zambia and confusion with Ptychadena pumilioSpawls, Wasonga, and Drewes, 2019, Amph. Kenya: 42, provided a photograph, range map, and brief characterization. Channing and Rödel, 2019, Field Guide Frogs & Other Amph.
