Rhipicephalus nitens Neumann, 1904 . Afrotropical: 1) South Africa ( Walker et al. 2000 , Horak et al. 2018 ). Walker et al. (2000) cautioned that all parasitic stages of Rhipicephalus nitens can be very difficult to separate from those of Rhipicephalus appendiculatus and Rhipicephalus duttoni . Doss et al. (1974c) listed several authors that allegedly found Rhipicephalus nitens in “north Africa,” Democratic Republic of the Congo , Kenya and Uganda , but Walker et al. (2000) did not regard records from outside South Africa as valid, an opinion also accepted here.
