Material examined. Saudi Arabia: 1 ♂, Al-Baha, Hadabah Hamra [19°16'31"N, 41°48'35"E], 381 m, 15.iv.2016, sweep net on Acacia , leg. Ahmed M. Soliman ( EFC) ; Egypt: 1 ♀, South Sinai, St. Catherine, Wadi Gebal [28°31'54''N; 33°54'18''E], 29.iv.2013, Malaise trap, leg. Edmardash ( EFC) .

Diagnosis. MALE: Body length: 7.0 mm; fore wing length: 4.0 mm. Morphometric ratios: Cxl/Cxh 3.58; Cxl/ Fml 0.8; tw/iEE 0.76; btl/btw 7.5; Pnl/Smw 1.36; tw/io 0.77; Pnl/Ew 1.93; GSl/Ptl 1.8; Ptl/T3l 2.0; Hdl/Ew 2.47; Ew/Tw 1.4; iEE/eEE 0.62; Ppl/Ew 1.66; io/oo 8.0; Ptl/alinotum 1.26; 1Cu/1cu-a 1.26.

This species is characteriZed by the presence of very large double whitish spots on sub-basal area of T4 that are very close and nearly touching each other ( Figs 18 & 21 ); petiole with basal 0.4 and subapical 0.1 ivory ( Figs 18 & 21 ); antenna yellowish and gradually darkened towards apex ( Fig. 18 ); all legs dark brown to black, except tarsi are all yellowish ( Fig. 18 ); vertex with area anterior to it with a large U-shaped carina followed by shorter transverse carina ( Fig. 19 ). Pronotal colo transversely strigate, rest of pronotum alutaceus ( Fig. 20 ); hind coxa coarsely transversely strigate ( Fig. 22 ), hind femur finely transversely striated ( Fig. 22 ); hind femora with small sub-basal tooth, a larger median and subapical triangular teeth and 2̄3 unequal tubercles in between as well as other 2 tubercles beyond last (subapical one), apices of all tubercles with a single fine short hair ( Fig. 22 ).

It differs from the Egyptian female in having body length 7.0 mm (in female 9.11 mm). Comparative morphometrics: Cxl/Cxh 3.58 (female 3.67); Cxl/Fml 0.8 (0.88); tw/iEE 0.76 (0.47); btl/btw 7.5 (5.94); Pnl/Smw 1.36 (1.29); tw/io 0.77 (0.59); Pnl/Ew 1.93 (1.99); GSl/Ptl 1.8 (1.19); Ptl/T3l 2.0 (2.24); Hdl/Ew 2.47 (1.99); Ew/ Tw 1.4 (1.49); iEE/eEE 0.62 (0.59); Ppl/Ew 1.66 (1.71); io/oo 8.0 (8.91); Ptl/alinotum 1.26 (2.2); 1Cu/1cu-a 1.26 (1.2). The body generally dark brown to black (in female the dark areas are reddish brown, lighter in color); two ivory spots on T4 very large and nearly touching each other (in female the two spots are quadrate and separated from each other by distance shorter than the diameter of each spot); hind coxa and femur finely transversely striated (alutaceus in female).

Distribution. Egypt ( Gadallah & Edmardash 2015), UAE (Aguiar & Jennings 2010; Aguiar et al. 2010), Saudi Arabia (Al-Baha region) (new record).
