description: Arachnospila (Ammosphex) kasparyani Loktionov & Lelej, sp. nov.
(Figs 8–10, 21, 22)
Type material. Holotype, ♂, RUSSIA, Tuva, 13 km SW Samagaltai, Dyttyg-Khem River, 8.VII.2013 (V. Loktionov, M. Proshchalykin) [IBSS]. Paratype, 1 ♂, RUSSIA, Tuva, 13 km SW Samagaltai, Dyttyg-Khem River, 19.VII.2014 (AL, MP, VL) [IBSS].
Diagnosis. MALE. Apical half of volsella lacking setae. Penial valve apically without spicules. Metasomal T1 and basal half of T2 ferruginous-red. FEMALE. Characters unknown
Description. MALE. Length of body 6.0– 6.5 mm. Length of fore wing 4.5–5.0 mm. Width of head 1.1× its height. Ocelli small, ratio POD/OOD 1.0–1.1 ×. Width of gena medially 0.4–0.5 × width of eye medially (lateral view). Clypeus weakly convex, anterior border weakly emarginate with narrow smooth rim. Labrum weakly convex, anterior border straight. Malar space weakly developed. Length of flagellomere 1 2.0 × its width. Relation of scape, pedicel and two first flagellomeres 30:13:24:26. Apical flagellomere pointed on the apex. Length of mesosoma dorsally 2.0–2.1 × its maximum width. Length of pronotum medially 0.4 × its width; posterior pronotal border angulate. Pronotum weakly broadened posterad, with more or less parallel sides. Length of metanotum medially 1.3–1.4 × length of metapostnotum. Metapostnotum matt with distinct or indistinct delicate transverse striae, posterior border without median smooth shiny triangle. Length of propodeum medially 0.7 × its maximum width. Wings slightly infuscated; fore wing with darker apical part as in Fig. 21; hind wing as in Fig. 22. Posterior border of S6 arcuate, emarginated. Hypopygium as in Figs 9, 10. Genitalia as in Fig. 8.
Gena and propleura with pale brown scattered erect setae. Mandible with few strong curved setae. Other body parts lacking setae. Body with iridescent mainly silver pubescence. Legs with sparse brownish pubescence. Body regularly micropunctate. Body and legs black. Mandible brownish apically; T1 (except extreme basal portion), T2 (except apical half) and S2 (except apical half) ferruginous-red.
FEMALE. Unknown.
Comparison. The male of this species is very similar to those of Arachnospila (Ammosphex) ausa (Tournier, 1890) and A. (A.) orientausa Loktionov & Lelej, 2011 by having similar shape of genitalia and hypopygium. New species clearly differs from A. (A.) orientausa by lacking setae in apical half of volsella (with setae in A. (A.) orientausa), and differs from A. (A.) ausa by having penial valve apically without spicules (with three spicules in A. (A.) ausa), as well as by having ferruginous-red T1 and basal half of T2 (ferruginous-red T1, T2 and basal portion of T 3 in A. (A.) ausa). The differences from other males of the subgenus Ammosphex, which are distributed in the Russian Far East and East Siberia, are given in the key below.
Etymology. Named after Dmitriy R. Kasparyan [ZISP], an excellent authority in Ichneumonidae.
Distribution. Russia (Tuva).
Ecology. Inhabits steppe areas, where occurs in riverside forest biotopes.
