19. Hyalomma nitidum Schulze, 1920 .

Afrotropical: 1) Benin, 2) Burkina Faso, 3) Cameroon, 4) Central African Republic, 5) Chad (south), 6) Equatorial Guinea, 7) Guinea, 8) Ivory Coast, 9) Mali (south), 10) Nigeria, 11) Senegal (Tomassone et al. 2005, Apanaskevich & Horak 2008 a, Uilenberg et al. 2013, Ouedraogo et al. 2021b).

Apanaskevich & Horak (2008a) emphasized the difficulties involved in morphologically separating adults of Hyalomma albiparmatum, Hyalomma nitidum and Hyalomma truncatum, adding that it is not possible to differentiate their larvae and nymphs. Thereafter, Sands et al. (2017b) stated that Hyalomma nitidum is most probably a synonym of the “northern lineage” of Hyalomma truncatum, a view supported by molecular evidence, while Schulz et al. (2020) stated that additional genetic studies are needed to confirm the hypothesis of Sands et al. (2017b).

Perveen et al. (2021) listed Hyalomma nitidum as found in Mauritania, based on Sylla et al. (2008), but the latter authors reported the presence of this tick only in southern Senegal.
