This species was previously recorded from Saudi Arabia by Dawah & Abdullah (2009) . It was described from Eritrea (as “ Ethiopia ”). In the Middle East it has been recorded from Oman and the United Arab Emirates ( Pont 1991 ; Deeming 2008 ). FIGURE. 28–31.

Biological remarks. Hosts include the Rhodes grass ( Chloris gayana Kunth ) which is grown widely in Arabia for feeding livestock and horses. Also it attacks cultivated Sorghum bicolor (L.) Moench and several other cereals and grasses ( Deeming 1971 ; 2000 ; 2008 ; Skidmore 1985 ; Pont 1991 ). In Oman this species is a serious pest of Rhodes grass ( Deeming 2000 ) and in Ethiopia of the staple cereal tef ( Eragrostis tef (Zucc.) Trotter ) ( Nigus & Damte 2018 ). Deeming (2019) deals in detail with larval diagnosis, various aspects of biology of immature stages, parasitic Hymenoptera and distribution of this species.
