( Fig. 8 ) Type locality. Duars ( Jalpaiguri District ), Nagpur and the Jeypore Hill Tracts , India . Distribution. This species is found in the Afrotropical, Oriental and Palaearctic Regions ( Azari-Hamidian et al. 2019 ). In the Middle East, it occurs in Bahrain , Iran , Iraq , Oman , Saudi Arabia , United Arab Emirates and Yemen ( Knight 1953b ; Mattingly & Knight 1956 ; Kouznetsov 1976 ; Büttiker 1981 ; Wills et al. 1985 ; Service 1986 ; Minář 1991 ; Glick 1992 ; van Harten & Wagener 1994 ; Pecor et al. 2002 ; Knio et al. 2005 ; Rueda et al. 2008 ; Alahmed 2012 ; Al Ashry et al. 2014 ; Irish et al. 2016 ; Alahmed et al. 2019 ; Azari-Hamadian et al. 2019; Wilkerson et al. 2021 ). It was recorded for the first time in Saudi Arabia by Mattingly & Knight (1956) . Remarks. The An. fluviatilis complex includes three species, informally designated as species S, T and U, based on polytene chromosome banding patterns observed in populations in southern Asia. The species are not morphologically distinguishable ( Chen et al. 2006 ; Singh et al. 2006 ; Harbach 2013 ; Azari-Hamidian et al. 2019 ). Alahmed et al . (2019) stated that An. fluviatilis may consist of one or two of these informally designated species in Saudi Arabia . Therefore, it is important to investigate which species of the complex are present in the country. Medical importance. The An. fluviatilis complex includes important vectors of malaria in Asian countries ( Dev & Phookan 1998 ). One or more of the species is suspected of being a malaria vector in Yemen ( Kouznetsov 1976 ; Al-Eryani et al . 2016 ).
