Diagnosis of male. The male of this species is easily distinguished from other males of the subgenus Ammosphex by having hypopygium not narrowed subbasally, gradually convergent to the apex, without any median carinae, and with one tuft of setae (not bristles) baso-laterally (Figs 15, 16 vs. 1–14, 17–37). Genitalia as in Fig. 48.
Diagnosis of female. The female of this species is similar to female of Arachnospila (Ammosphex) wolfi Lelej, 1995 by having ratio of eye width to half frontal width 0.9 and more, but clearly differs by having shiny frons (matt in A. (A.) wolfi) and propodeum laterally with long erect sparse setae (without long erect setae, at most with a few short setae in A. (A.) wolfi). Clypeus as in Fig. 58. Metapostnotum as in Fig. 78. Venation of fore wing as in Figs 96, 97.

Biology. The cleptoparasites of Arachnospila (Ammosphex) anceps are pompilids: Ceropales maculata (Fabricius) (Lelej 1995) and Evagetes crassicornis (Shuckard) (v.d. Smissen 2003).
The prey consists of spiders Clubiona Latreille (Clubionidae), Drassodes Westring (Gnaphosidae), Alopecosa Simon, Pardosa C.L. Koch, Trochosa C.L. Koch (Lycosidae), Pisaura Simon (Pisauridae), Evarcha Simon (Salticidae), Xysticus C.L. Koch (Thomisidae) (WiŠniowski 2009).
Female excavates a short burrow in the ground ending in a single cell. During excavation the paralyzed spider is hidden on a plant (WiŠniowski 2009).
