Rhipicephalus pulchellus ( Gerstäcker, 1873 ) . Afrotropical: 1) Djibouti , 2) Eritrea , 3) Ethiopia , 4) Kenya , 5) Somalia , 6) Tanzania , 7) Uganda ( Yeoman & Walker 1967 , Walker 1974 , Morel 1980 , Matthysse & Colbo 1987 , Iori et al. 1996 , Walker et al. 2000 , Lynen et al. 2007 , Kolonin 2009 , Byaruhanga et al. 2021 , Olivieri et al. 2021 ). The female, nymph and larva of Rhipicephalus pulchellus are morphologically close to the corresponding stages of Rhipicephalus humeralis , but the males of these species are easily separated morphologically ( Walker et al. 2000 ). Burridge (2011) listed Sudan within the natural range of Rhipicephalus pulchellus , but its presence there was not confirmed during this analysis. Okely et al. (2021 , 2022 ) listed records of this tick from Egypt but stated that it is a non-endemic tick. Egypt is therefore not included within the range of Rhipicephalus pulchellus .
