Abstract:
Presented is a diagnosis of the male, female and nymph of Dermacentor rhinocerinus, and the first
description of the larval stage. Adult Dermacentor rhinocerinus parasitize both the black rhinoceros,
Diceros bicornis, and the white rhinoceros, Ceratotherium simum. Although various other large
mammals have been recorded as hosts for D. rhinocerinus, only the two species of rhinoceros are
primary hosts for adults in various areas of east, central and southern Africa.
Adults collected from vegetation in the Kruger National Park, Transvaal, South Africa were reared on
rabbits at the Onderstepoort Veterinary Institute, where larvae were obtained for the first time.
