Removed from the synonymy of Cacosternum boettgeri by Channing, 2001, Amph. Cent. S. Afr.: 292, where it had been placed by Poynton, 1964, Ann. Natal Mus., 17: 146. Channing, Brun, Burger, Febvre, and Moyer, 2005, Afr. J. Herpetol., 54: 145, noted that this species is only critically distinguishable from Cacosternum boettgeri by call. Pickersgill, 2007, Frog Search: 286-290, provided an account and discussed the ambiguity of application of the name. See also account by Du Preez and Carruthers, 2009, Compl. Guide Frogs S. Afr.: 376-377. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543-583, in their molecular study, suggested that Cacosternum platys is the sister taxon of Microbatrachella, this likely due to use of misidentified Genbank sequences ifrom Frost, Grant, Faivovich, Bain, Haas, Haddad, de Sá, Channing, Wilkinson, Donnellan, Raxworthy, Campbell, Blotto, Moler, Drewes, Nussbaum, Lynch, Green, and Wheeler, 2006, Bull. Am. Mus. Nat. Hist., 297, that are actually Microbatrachella capensis according to Channing, Schmitz, Burger, and Kielgast, 2013, Zootaxa, 3701: 536, who also provided comments on the biology of this species. Channing, Rödel, and Channing, 2012, Tadpoles of Africa: 337–338, provided information on comparative larval morphology. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 372–373, provided a brief account, photograph, and range map.
