(Figs 28−32)
Material examined. Holotype ♂: Egypt, Nahia, Giza [30°02'54"N, 31°07'40"E], 23.xi.1932 (leg.?) [CUE].
Description. MALE (holotype). Body length 11 mm. Colour. Black, except antenna, pronotum, metapleuron, posterior two-thirds of scutellum, tegula, metanotum, propodeum, metapleuron, legs, first metasomal segment and terminal hook ferruginous red; mandible ferruginous on basal third, reddish brown apically; palpi dark brown; scutellum and mespleuron partly red; T3−T7 chestnut posteriorly. Wings hyaline with yellow veins and pterostigma brown. Fore tibial spur reddish, mid and hind ones waxy white; eye black. Pubescence. Body including legs densely clothed with erect to recumbent white setae, such setae masking background of face, clypeus, pronotum and anterior half of mesoscutum; T1, T2 with well defined tuft of dense long white setae apicomesally (Fig. 31); metasomal segments 3−6 with well-developed apical fringe of white setae.
Head. In dorsal view slightly narrower than pronotum (0.8 ×) and convergent behind eyes; vertex punctulate, with a smooth area adjacent to each ocellus, with a distinct polished tubercle posterolaterally closer to eye than lateral ocellus; ocellocular distance (OOD) as long as interocellar distance (IOD); malar space 0.35 × LED; mandible slender, with very small subapical tooth. Antenna long, 2 × as long as mesosomal length; scape subquadrate, 0.7 × as long as its maximal width, distinctly shorter than F1 (0.2 ×); F1 distinctly long, 5 × as long as its width, slightly longer than F2 and 1.25 × as long as F3.
Mesosoma. Pronotum declivous in front, transversely ridged posterolaterally, with strongly concave posterior margin and broadly rounded humeral angle; basal half of mesoscutum and scutellum densely punctate, the former with median longitudinal polished ridge extending along its anterior half; notauli complete, strongly divergent anteriorly (Fig. 29); tegula smooth and bare; propodeal dorsal face areolate, posterior face abruptly declivous, shallowly concave and smooth (Fig. 30); hind coxa with strong lamina on outer surface. Mesopleuron punctatereticulate, with smooth area in front of mid coxa. Fore wing with closed brachial cell; hind wing with eight hamuli. Front femur swollen distally; hind inner tibial spur slightly shorter than basal tarsomere.
Metasoma. T1−T3 moderately reticulate-foveate (Figs 31, 32); T4−T7 finely punctate; S1 with distinct transverse carina posteriorly; S2, S3 densely punctate-reticulate, the latter with transverse smooth area subapically; S4−S6 with transverse smooth ridge widened medially, become finely punctate-reticulate laterally; S6 with a group of short reddish bristles laterally; S7 with transverse smooth ridge basally and puncticulate apically.
FEMALE unknown
Distribution. Egypt: Giza.
Remarks. This species closely resembles Apterogyna olivieri but differ in the following: with red pronotum and metapleuron, while scutellum and mesopleuron are partly red (all are entirely black in A. olivieri); mesosoma densely clothed with recumbent setae masking background beneath particularly on pronotum and anterior half of mesoscutum (Figs 28, 29) (mesosoma with scattered erect setae in A. olivieri (Fig. 20)); propodeal posterior face smooth (Fig. 30) (reticulate-punctate in A. olivieri); metasomal T1 and T2 with well-developed tufts of whitish setae apicomesally (Fig. 31) (ill-defined in A. olivieri (Fig. 22)); metasomal T3 densely and deeply punctate (Fig. 32) (with scattered superficial punctures in A. olivieri (Fig. 22)).
Etymology. The name similis (Latin, adjective) refers to the similarity of this species with A. olivieri Klug.
