30. Rhipicephalus geigyi (Aeschlimann & Morel, 1965). Afrotropical: 1) Benin, 2) Burkina Faso, 3) Cameroon, 4) Central African Republic, 5) Chad (south), 6) Gambia, 7) Ghana, 8) Guinea, 9) Guinea-Bissau, 10) Ivory Coast, 11) Liberia, 12) Mali (south), 13) Niger (south), 14) Nigeria, 15) Senegal, 16) Sierra Leone, 17) South Sudan, 18) Sudan, 19) Togo, 20) Uganda (Keirans 1985 b, Matthysse & Colbo 1987, Terenius et al. 2000, Morel 2003, Walker et al. 2003, Ntiamoa-Baidu et al. 2004, ElGhali & Hassan 2012, Lorusso et al. 2013, Uilenberg et al. 2013, Kartashov et al. 2021, Ouedraogo et al. 2021 b, Sylla et al. 2021). Many records of Rhipicephalus geigyi have been published under the name Boophilus geigyi. Rhipicephalus geigyi was widely confused with Rhipicephalus decoloratus prior to its description by Aeschlimann & Morel (1985). Ronghang & Roy (2016) allegedly found Rhipicephalus geigyi in India (Oriental Zoogeographic Region), but its presence there requires confirmation, as well as the claim by Kobayashi et al. (2020) that this species is present in Zambia (Afrotropical Region).
