Comment

See accounts by Poynton, 1964, Ann. Natal Mus., 17: 146–147, Poynton and Broadley, 1985, Ann. Natal Mus., 27: 174, Lambiris, 1988, Lammergeyer, 39: 110–111, Channing, 2001, Amph. Cent. S. Afr.: 287–288, Pickersgill, 2007, Frog Search: 284–286, and Du Preez and Carruthers, 2009, Compl. Guide Frogs S. Afr.: 364-365. See comment under Cacosternum striatus. Largen, 2001, Tropical Zool., 14: 344, commented on distribution. Channing and Howell, 2006, Amph. E. Afr.: 263-264, removed the Tanzania and Kenya population from this taxon as "Plimpton's Dainty Frog" (Cacosternum plimptoni). With the removal of "Plimpton's Dainty Frog" the status of the Ethiopian population remains questionable as noted by Zimkus, 2008, Herpetol. Rev., 39: 233. Bates and Haacke, 2003, Navors. Nas. Mus. Bloemfontein, 19: 1137–138, discussed the species in Lesotho. See account, photograph, and map for Ethiopia by Largen and Spawls, 2010, Amph. Rept. Ethiopia Eritrea: 198–199. Channing, Schmitz, Burger, and Kielgast, 2013, Zootaxa, 3701: 529–530, commented on this species and placed it phylogenetically and suggested that the Ethiopian population assigned to this species almost certainly is an unnamed species. Channing, Rödel, and Channing, 2012, Tadpoles of Africa: 332, provided information on comparative larval morphology.
