In The Arthropod Parasites of Vertebrates in Africa South of the Sahara (Ethiopian Region) edited by F. Zumpt (1961), Dr. R. F. Lawrence compiled the trombidiform mites and listed in the genus Radfordia Ewing (syn: Austromyobia Lawrence and Cryptomyobia Radford) the following species: R. affinis (Poppe), R. davisi (Radford), R. ensifera (Poppe), R. forcipifer Lawrence and R. rotundata (Lawrence). Radfordia davisi was based on a single nymphal specimen, found on the Norwegian Rat (Rattus norvegicus (Berkenhout)), at Freetown, Sierra Leone. We have not seen the holotype or any specimens which could be referred to it, and it is also not comparable with the other specimens listed above, which are based on the adult stage. Specimens of the other four species are before us, as well as two new species, namely R. elegantula from the Pygmy Mouse (Mus minutoides A. Smith) and R. praomys from the Multimammate Rat (Praomys natalensis (A. Smith)). All these will be discussed in alpha­betic order.
