( Figs 1−21 View FIGURES 1−3 View FIGURES 4−9 View FIGURES 10−16 View FIGURES 17−20 View FIGURE 21 )

Diagnosis. The new species is close to North African species, P. dewitzi (Kohl, 1889) , sharing with it the following characters: mandibles yellow except at apex; pronotal collar light yellow and notched medially, laterally rounded; head behind compound eyes distinctly narrow; mid basitarsus with four spines; pygidial plate rounded apically. The new species differs from P. dewitzi and other related species of Pseudoscolia by the body size, free margin of clypeus slightly emarginate mesally, basomedian area slightly emarginate apically; postocellar area densely punctate; compound eyes not reaching mandibles; pronotal collar with shallow notch medially; scutellum completely black; mesopleuron densely reticulo-punctate dorsally; fore basitarsus with five spines; Gt 1 -Gt 5 each with yellowish white fascia, densely punctate antero-dorsally, Gs 1 -Gs 5 immaculate, pygidial plate triangular, broad basally with lateral carina, micro-sculptured. New species also differs from the species described from Central Asia and Arabia by the body size, emarginate clypeal median lobe, scutellum coloration, medial notch on pronotal collar, coloration & bands on metasoma and punctation on body as described below.
