Two new species of ticks from southern Africa whose adults parasitize the feet of ungulates: Rhipicephalus lounsburyi n. sp. and Rhipicephalus neumanni n. sp. (Ixodoidea, Ixodidae).
Theiler & Robinson (1953) described, as Rhipicephalus follis Dönitz, 1910, a tick species originating from Dordrecht, Eastern Cape Province. A comparison of this tick with the syntypes of R. follis has now shown, though, that these 2 entities are different and it is therefore redescribed below as Rhipicephalus lounsburyi n. sp. Its adults parasitize sheep and various wild ungulates, attaching primarily on their feet. The hosts of the immature stages are still unknown. It has now been recorded from several places in the Eastern Cape; once in Natal, at Impendle, and in the Western Cape near Swellendam and between Clanwilliam and Graafwater. A second species, which has in the past been confused with the dassie parasite, Rhipicephalus distinctus Bedford, 1932, is described as Rhipicephalus neumanni n. sp. Its adults also attach on the feet of sheep and goats. The hosts of the immature stages are unknown. It has been widely recorded in the Bethanien and Keetmanshoop Districts of Namibia and, in South Africa, from scattered localities in the Karoo.
