Comment

See Laurent, 1972, Ann. Mus. R. Afr. Cent., Tervuren, Ser. Octavo, Sci. Zool., 194: 1-67, for the most recent revision of this genus. See Poynton, 1978, J. Herpetol. Assoc. Afr., 19: 8, and Frost and Savage, 1987, J. Herpetol. Assoc. Afr., 33: 24, for nomenclature; Hemisus, although linguistically neuter in gender must be treated as if it were masculine for reason of Article 30.1.3 of ICZN, 1999, Internatl. Code Zool. Nomencl., Ed. 4: 35. Channing, 2001, Amph. Cent. S. Afr.: 119-120, provided a key to the species of southern Africa. Channing and Howell, 2006, Amph. E. Afr.: 124-125, provided a key and accounts for East Africa. Du Preez and Carruthers, 2009, Compl. Guide Frogs S. Afr.: 214-221, provided a key and accounts for the species of southern Africa. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 112–115, provided brief accounts, photographs, and range maps for the species.
