161. Ixodes nairobiensis Nuttall, 1916 .

Afrotropical: 1) Democratic Republic of the Congo, 2) Kenya, 3) Malawi, 4) South Sudan, 5) Tanzania, 6) Uganda ( Elbl & Anastos 1966b, Yeoman & Walker 1967, Walker 1974, Matthysse & Colbo 1987, Kolonin 2009).

Elbl & Anastos (1966b), Morel (2003) and Kolonin (2009) included South Africa within the geographic distribution of Ixodes nairobiensis , but Theiler (1962), Walker (1991) and Horak et al. (2018) rejected the presence of this tick in that country, stating that Ixodes nairobiensis has been confused with Ixodes elongatus , and Theiler (1962) believed that Ixodes nairobiensis had also been confused with South African specimens of Ixodes bedfordi . Consequently, we do not include South Africa within the range of Ixodes nairobiensis . Hoogstraal (1956a) listed Ixodes nairobiensis as an East African tick, but Hoogstraal (1956a) and Morel (2003) included Angola and Zimbabwe within its range. Elbl & Anastos (1966b) treated the records in Hoogstraal (1956a) as valid, but Angola and Zimbabwe were not included within the range of Ixodes nairobiensis by Kolonin (2009). Angola and Zimbabwe are here provisionally considered to lie outside the geographic distribution of Ixodes nairobiensis .
