Culex (Culex) duttoni Theobald, 1901c (Fig. 29)

Type locality. Duke Town, Nigeria.

Distribution. This species is widespread in the Afrotropical Region (Wilkerson et al. 2021). In the Middle East and North Africa, it occurs in Morocco, Saudi Arabia and Yemen (Lewis 1956; Mattingly & Knight 1956; White 1980; Harbach 1985; Brunhes et al. 2000; Abdoon 2004; Al-Ali et al. 2008; Tantely et al. 2016; Lemine et al. 2017; Wilkerson et al. 2021). It was recorded for the first time in Saudi Arabia by Abdoon (2004).

Remarks. Culex duttoni combines features of the Pipiens and Sitiens Groups. It has a ringed proboscis and ringed tarsi similar to the species of the Sitiens Group and 2 to 4 lower mesepimeral setae like species of the Pipiens Group. That is why it is classified in a separate group (Duttoni Group) (Harbach 1988, and see key below).

Medical importance. Culex duttoni is involved in the transmission of Yaoundé and Uganda S viruses in Africa (Adam & Digoutte 2005; Tantely et al. 2016).
