Old Calabar , Nigeria . Distribution. This species is widespread in the Afrotropical Region ( Wilkerson et al. 2021 ). In the Middle East, it occurs in Saudi Arabia and Yemen ( Edwards 1914 ; Knight 1953b ; Lewis 1956 ; Mattingly & Knight 1956 ; White 1980 ; Büttiker 1981 ; Miller et al. 2002 ; Lemine et al. 2017 ; Wilkerson et al. 2021 ). It was recorded for the first time in Saudi Arabia by Büttiker (1981) . Remarks. Culex nebulosus is the only representative of its subgenus in the region ( Harbach 1988 ). Medical importance. In Africa, this species is involved in the transmission of Ntaya virus ( Brottes et al. 1966 ) and Babahoyo, Bagaza, M’Poko, Middelburg, Tai and Yaoundé viruses ( Adam & Digoutte 2005 ; Tantely et al. 2016 ). Females of Cx. nebulosus rarely attack humans ( Kerr 1933 ).
