Dreyer (1935) provided the first description of the Florisbad skull and assigned it to a new species Homo (Africanthropus) helmei Dreyer, 1935. Writing shortly after, Drennan (1935) interpreted the skull as more closely resembling Neanderthals and thus offered an alternative name, Homo forisbadensis (helmei). As both names refer to the same type specimen, Drennan's is an objective junior synonym to Homo (Africanthropus) helmei Dreyer, 1935.
