Comment

Discussed by Perret, 1988, Arch. Sci., Genève, 41: 279–281. See Largen and Dowsett-Lemaire, 1991, Tauraco Res. Rept., 4: 151–152, for Rep. Congo records. Frétey and Blanc, 2002 "2001", Bull. Soc. Zool. France, 126: 386, reported this species from Gabon. Frétey, 2008, Alytes, 25: 99–172, summarized the literature. Jacobsen, 2009, Afr. Herp News, 47: 2–20, reported this species from east-north-central Central African Republic. In species group B of Zimkus, Rödel, and Hillers, 2010, Mol. Phylogenet. Evol., 55: 883–900. Nagy, Chifundera, Collet, and Gvoždík, 2013, Herpetol. Notes, 6: 413–419, provided a record from Bas-Congo, southwestern Dem. Rep. Congo. Baptista, Conradie, Vaz Pinto, and Branch, 2019, In Huntley, Russo, Lages, and Ferrand (eds.), Biodiversity in Angola: 256, noted specimens in Luki, Dem. Rep. Congo, near Angola (both the Cabinda enclave and northwestern Angola proper), suggesting its possible occurrence there. Dewynter and Frétey, 2019, Cah. Fondation Biotope, 27: 33, summarized the literature for Gabon and provided a photograph (p. 61). Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 298–299, provided a brief account, photograph, and range map. In the Phrynobatrachus calcaratus group of Goutte, Reyes-Velasco, and Boissinot, 2019, ZooKeys, 824: 53–70. See brief account and range map for Equatorial Guinea in Sánchez-Vialas, Calvo-Revuelta, Castroviejo-Fisher, and De la Riva, 2020, Proc. California Acad. Sci., Ser. 4, 66: 137–230.
