Unless otherwise stated the records in the host/parasite checklist refer to adult ticks. The number in brackets appearing after a tick's name represents the number of collections made from the host species under which it is listed. It has been difficult to determine the exact number of records for R. fulvus. Consequently where the name of this tick appears in the host/parasite list it is followed by (+) which indicates that it has been collected from a particular host species.

When a tick's name appears in bold type this indicates that the animal under which it is listed is a preferred host of the adults. However, when the hosts of the immature stages are entirely unrelated to those of the adults the names of these ticks also appear in bold type under the names of the preferred hosts of their immature stages. These ticks are R. follis, R. gertrudae and R. simus. When more collections of their immature stages have been made we feel sure that the same will apply for R. compositus, R. lounsburyi, R. lunulatuSy R. muhsamae, R. neumanni, R. planus, R. praetextatus, R. senegalensis and R. zumpti and perhaps other species too.

Despite the fact that the immature stages of R. pravus, R. sp. near pravus and R. warburtoni are found on hares, on which their adults also occur, they undoubtedly have a preference for elephant shrews. The names of these ticks are also typed in bold under their respective elephant shrew hosts. We are confident that the same will apply for R. punctatus and R. sp. near punctatus once additional collections of their immature stages have been made.
