The male of this species is similar to males of Arachnospila ( Ammosphex ) yasumatsui Wolf and Móczár, 1972 and A . ( A .) wolfi Lelej, 1995 by having flattened hypopygium with short erect scattered setae, but is easily distinguished from the former by having penial valve not narrowed preapically and rounded apically (Fig. 47 vs . 51), and differs from the latter by having penial valve less setose, not constricted preapically (Fig. 47 vs . 52), by metasomal segments 1 and 2 ferruginous-red (metasomal terga 1 and 2 at most with brown-reddish spot baso-laterally in A . ( A .) wolfi ). Genitalia as in Fig. 47. Diagnosis of female. The female of this species differs from other females of the subgenus Ammosphex by having ratio of eye width to half frontal width 0.8 and less (0.9 and more in Arachnospila ( Ammosphex ) anceps (Wesmael, 1851) and A . ( A .) wolfi Lelej, 1995), by protarsomere 1 with three short spines of tarsal comb (four long spines in A. ( A. ) kaszabi Wolf and Móczár, 1972), by first flagellomere length 3.2–3.9 × its width (4.1 × and more in other females), by apical flagellomere length almost 3 × its width (2 × in A. ( A. ) orientausa sp. nov. ), and by mesopleuron and propodeum with silver or gray micropubescence (brownish micropubescence in some other females). Clypeus as in Fig. 72.

Biology. The cleptoparasite of Arachnospila ( Ammosphex ) trivialis is the pompilid Evagetes crassicornis (Shuckard) (v.d. Smissen 2003). The prey consists of spiders Pardosa C.L. Koch, Trochosa C.L. Koch (Lycosidae), Xysticus C.L. Koch (Thomisidae) and also Agelenidae, Clubionidae, Gnaphosidae (WiŠniowski 2009). Female nests in the ground mainly in pre-existing cavities, sometimes excavated in loose soil (WiŠniowski 2009). : Published as part of Loktionov, Valery M. & Lelej, Arkady S., 2011, Review of the subgenus Ammosphex Wilcke, 1942 of the genus Arachnospila Kincaid, 1900 (Hymenoptera: Pompilidae) of the Russian Far East and East Siberia, pp. 1-30 in Zootaxa 3137 on page 24, DOI: 10.5281/zenodo.202611 : {"references": ["Day, M.
