Material examined: 1♁, 1♀, Wadi Degla , 4.iv.1928 ( AUCE) ; 1♁, Suez Road , 15.ix.1929 ( AUCE) ; 1♁, Fayoum , 8.iii.1935 ( AUCE) ; 1♁, 1♀, Marsa Matruh, viii.1953, Dr. T. S. collector ( ASUA) ; 1♁, Kom Oshiem , 4.iv.1953, Aly collector ( ASUA) ; 1♁, Wadi El Natroun , 2.iv.1951, Roh. collector ( ASUA) .

Previous Egyptian Records: Tor (S. Sinai) ( Kohl 1891), Fayoum (El Khawagat), Kerdasa, Hammamat Faraoun (S. Sinai), Wadi Degla ( Mochi 1939; Honoré 1942; Roche 2007), Sinai Peninsula ( Roche & Zalat 1994), Dakhla Oasis, Kom Oshiem, Wadi El Natroun ( Gadallah 1996), Dahshour, Wadi El Tih ( Dollfuss 2017).

Extralimital distribution: Jordan, Kuwait, Libya, Sudan, United Arab Emirates.

Remarks. Characters of Egyptian specimens agree well with Guichard’s key (1994: 208, couplet 4). They also agree with de Beaumont’s description (1961: 202) as well as couplet 4 ( de Beaumont 1961: 211), but differ in the malar space length: in our specimens the male malar space equals 2/3 the length of F1, and about half length of F 1 in female (in male, equal to F1, and in female 2/3 length of F 1 in de Beaumont’s key). Our specimens agree also with de Beaumont’s figs 4, 5 (1961: 207).
