Diagnosis of male. The male of this species is easily distinguished from other males of Arachnospila (Ammosphex) abnormis -species group (hypopygium ventro-preapically with tuft of long erect setae medially) by roof-like hypopygium without any row of setae or bristles baso-laterally (Figs 9, 10 vs. 1–8, 11, 12). The male of this species differs from very similar A. (A.) kurentzovi Lelej, 1995 by having hypopygium rounded apically (acuminate apically in A. (A.) kurentzovi) (Fig. 9 vs. 7). Genitalia as in Fig. 41.

Diagnosis of female. The female of this species is similar to that of Arachnospila (Ammosphex) abnormis (Dahlbom, 1842) by having apical spine of first protarsomere more than 0.5 of protarsomere 2 in length, by shiny frons, by ratio of first flagellomere length to its width 3.2–3.9, and by protarsomere 1 with three spines, but clearly differs by curved 2rs-m vein of fore wing (straight 2rs-m vein in A. (A.) abnormis) (Fig. 106 vs. 95). Clypeus as in Fig. 64. Metapostnotum as in Fig. 84.
