An Afrotropical species, all of whose parasitic stages are usually found on Rodentia: Thryonomyidae; adults and nymphs have been collected from Rodentia: Hystricidae, while adult ticks have been recovered from Mammalia (several orders). There are no records of Rhipicephalus simpsoni causing human parasitism.

Note: Santos Dias (1951b) described the nymph and redescribed the male and female of Rhipicephalus simpsoni . However, the nymph in Santos Dias (1951b) differs morphologically from the nymphs of Rhipicephalus simpsoni in Clifford and Anastos (1964) and Walker et al. (2000) with respect to the spurring of coxae II-III, and we therefore have provisionally excluded the description and redescriptions of Rhipicephalus simpsoni in Santos Dias (1951b) from the above lists.
