Material examined. Holotype of Didineis bucharica Gussakovskij—♂, Uzbekistan, Guzar, 26.V 1929 (Antova) ( ZIN).

Recognition. Didineis bucharica is related to D. crassicornis , both species having an unusually short flagellum (flagellomeres VI–IX as long as wide in female and shorter than wide in male). The female of D. bucharica differs in having a densely punctate and shiny lateral surface of the mesopleuron (finely rugose and mat in crassicornis ) and the practically impunctate metasomal tergum II (finely and somewhat densely punctate in crassicornis ). The male is unique in having flagellomeres I–III concave ventrally ( Fig. 2 ).

Description. Body black. Metasomal base red in female ( Schmid-Egger 2011), black in male. Clypeus, band on inner eye margin, and scape yellow. Flagellum black in female, reddish ventrally and black above in male. Legs black with red foretibia in female ( Schmid-Egger 2011), red in male. Frons densely punctate (punctures less than one diameter apart). Scutum finely, somewhat sparsely punctate (punctures more than one diameter apart). Lateral surface of mesopleuron densely punctate (punctures less than one diameter apart), shiny. Metasomal tergum II practically impunctate. Female flagellomeres VI–IX as long as wide. Male flagellomeres I–III concave, flagellomeres VI–IX shorter than wide, foretibia not modified.

Distribution. United Arab Emirates, Uzbekistan.
