Comment

See accounts by Schmidt and Inger, 1959, Explor. Parc Natl. Upemba, Miss. G.F. de Witte, 56: 165–169, Inger, 1968, Explor. Parc Natl. Garamba, Miss. H. de Saeger, 52: 106–108, and Channing, 2001, Amph. Cent. S. Afr.: 310–311. Loveridge's records for Mozambique and Malawi are based on Phrynobatrachus acridoides; see Poynton, 1964, Ann. Natal Mus., 17: 140–141. See Poynton and Broadley, 1985, Ann. Natal Mus., 27: 158. Records of Phrynobatrachus perpalmatus from Cameroon by Perret and Mertens, 1957, Rev. Suisse Zool., 64: 73–78, are based on specimens of Phrynobatrachus steindachneri according to J.-L. Perret (personal communication). Channing and Howell, 2006, Amph. E. Afr.: 288–289, provided an account. Frétey, 2008, Alytes, 25: 99–172, summarized the literature and reported the species as occurring in Burundi, but without a specific locality. Not addressed by Zimkus, Rödel, and Hillers, 2010, Mol. Phylogenet. Evol., 55: 883–900, so not assigned to species group. Mercurio, 2011, Amph. Malawi: 231, provided an account for Malawi. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 272–273, provided a brief account, photograph, and range map. Gvoždík, Nečas, Dolinay, Zimkus, Schmitz, and Fokam, 2020, PeerJ, 8 (e8393): 1–52, discussed misidentifications.
