Abstract:
This tick, originally referred to as Rhipicephalus species Ill by Yeoman & Walker (1967), was first collected
from a sitatunga, Tragelaphus spekei, and then occasionally from cattle, in Tanzania. Further collections,
mostly from sitatunga, have since been seen from Uganda and Zambia. Descriptions of the adults of this
species are given, together with information on their hosts and their distribution.
