Diagnosis. Body length: 4.0 mm. Body colour: see Fig. 11 (A–F). Metanotum yellow; apex of median lobe of clypeus roundly projected, smooth and shiny ( Fig. 11B ); scutum densely finely punctate; punctures somewhat more spaced on scutellum, with more than a puncture diameter apart ( Fig. 11C ); metanotum smooth ( Fig. 11C ); depressed sides of scutellum densely finely pubescent; propodeum finely reticulate ( Fig. 11A, C ); mesepimeron with small rounded area smooth and shiny ( Fig. 11D ); fore and midfemora all black ( Fig. 11E ); fore and middle tibiae with small yellowish to whitish spot, hind tibia with whitish band along basal half dorsally. Material examined: 1♀ , Farasan, Abdulmajeed farm [16 Q 42.07970’N; 42 Q 08.5781’E], 23–30.ix.2022 . Distribution: Saudi Arabia (new record), Spain , Syria , United Arab Emirates . Comments. This species is a new record for Saudi Arabia . Characters of the specimens collected from Farasan agree with de Beaumont’s key (1964: 55, couplet 5). It differs from the Syrian specimens of de Beaumont (1964: 59) in having the pale areas of body yellowish (whitish in the Syrian specimens). It also agrees well with Schmid-Egger’s key (2011: 582, couplet 4).
