33. Rhipicephalus guilhoni Morel & Vassiliades, 1963 .

Afrotropical: 1) Burkina Faso, 2) Cameroon, 3) Central African Republic, 4) Chad (south), 5) Ethiopia, 6) Mali (south), 7) Mauritania (south), 8) Niger (south), 9) Nigeria, 10) Senegal, 11) South Sudan, 12) Sudan; Palearctic: 1) Chad (north), 2) Egypt ( Morel & Mouchet 1965, Pegram et al. 1987c, Walker et al. 2000, Morel 2003, Lorusso et al. 2013, Uilenberg et al. 2013, Sylla et al. 2021).

Rhipicephalus guilhoni had been confused with species of the Rhipicephalus sanguineus complex prior to its description by Morel & Vassiliades (1963), and Uilenberg et al. (2013) emphasized the extreme difficulties attending morphological separation of Rhipicephalus guilhoni from related species. Chitimia-Dobler et al. (2017b) suggested that Rhipicephalus camicasi is a synonym of Rhipicephalis guilhoni .

ElGhali & Hassan (2012) did not include South Sudan within the geographic distribution of Rhipicephalus guilhoni , but its presence in that country is based on Pegram et al. (1987c).

Bouhous et al. (2011) recorded specimens of Rhipicephalus guilhoni from Algeria, but according to these authors, additional studies are needed to confirm the presence of endemic populations in that country. Gargili et al. (2017) listed Rhipicephalus guilhoni as found in Uzbekistan based on a reference that does not support their statement, while Zambian records of this tick in Kobayashi et al. (2021) require confirmation.
