description: Arachnospila (Ammosphex) moczari Loktionov & Lelej, sp. nov.
(Figs 14–16, 25, 26)
Type material. Holotype, ♂, RUSSIA, 13 km SW Samagaltai, Dyttyg-Khem River, 9.VII.2013 (V. Loktionov, M. Proshchalykin) [IBSS]. Paratypes, RUSSIA, Tuva: 2 ♂, 20 km SSW Erzin, Tore-Khol Lake, 2, 3.VII.2013 (VL, MP); 1♂, 25 km SE Erzin, Tes-Khem River, 5.VII.2014 (VL, MP) [IBSS].
Diagnosis. MALE. Volsella apically broadened and rounded, inner side of volsella apically with a few short erect setae. Gonostyli densely covered with very long hairs. Hypopygium ventrally with maximum width on the midline. FEMALE. Characters unknown.
Description. MALE. Length of body 5.0– 6.5 mm. Length of fore wing 3.8–5.0 mm. Width of head 1.1–1.2 × its height. Ocelli small, ratio POD/OOD 1.0–1.2 ×. Width of gena medially 0.4–0.5 × width of eye medially (lateral view). Clypeus weakly longitudinally convex, anterior border emarginate, with narrow smooth rim. Labrum flat, anterior border straight. Malar space weakly developed. Length of flagellomere 1 1.8–2.1 × its width. Relation of scape, pedicel and two first flagellomeres 18–23:9–11:16–21:19–24. Apical flagellomere pointed on the apex. Length of mesosoma dorsally 1.9–2.1 × its maximum width. Length of pronotum medially 0.3–0.4´its median width, posterior pronotal border angulate. Pronotum distinctly broadened posteriorly, its anterior width 0.8 × maximum posterior width. Length of metanotum medially 1.2–1.5 × length of metapostnotum. Metapostnotum with 2–3 distinct (sometimes very fine) transverse striae near anterior border, and gentle micropunctation in posterior portion. Posterior border of metapostnotum with small median smooth shiny triangle. Median length of propodeum 0.7–0.8 × its maximum width. Wings slightly infuscated with darker apical part, venation of fore wing as in Fig. 25, venation of hind wing as in Fig. 26. Third radio-medial (submarginal) cell of fore wing trapeziform, or nearly trapeziform, or petiolate. Posterior border of S6 broadly arcuate, emarginated. Hypopygium as in Figs 15, 16. Genitalia as in Fig. 14.
Frons and vertex with few long pale brown erect setae. Gena and propleura with longer scattered pale-brown setae. Pronotum, sides of propodeum, fore coxa with few short, grey erect setae, or lacking setae. Mandible with few long pale brown curved setae. Other body parts lacking setae. Lower part of face, basal half of mandible, gena, pronotum, pleurae, propodeum, fore coxa with iridescent, mainly silver pubescence (denser on lower part of face). Ferruginous-red metasomal segments with silver micropubescence. Black metasomal segments and legs with brownish micropubescence. Body regularly micropunctate. Body and legs black. Sometimes outer eyes orbit with small yellowish spot; mandible dark brown apically; T1 (except extreme basal portion), T2 and T3 (except apical half), S1, S2 (completely or except apical portion) and sometimes S3 (except apical half) ferruginous-red.
FEMALE. Unknown.
Comparison. The male of this species is similar to European Arachnospila (Ammosphex) wesmaeli (Thomson, 1870) by having similar shape of hypopygium and genitalia, but differs from it by having few short erect setae along inner side of volsella apically (dense and long setae in A. (A.) wesmaeli), by having broadened and rounded volsella apically (narrowed and pointed in A. (A.) wesmaeli), by having maximum width of hypopygium ventrally midline (near to base in A. (A.) wesmaeli).
Etymology. Named after László Móczár, who celebrate in 2014 his hundredth birthday, and for his large contribution to the studies of Pompilidae.
Distribution. Russia (Tuva, Republic of Altai).
Ecology. Inhabits steppe areas, where occurs in sandy and forest biotopes along rivers and lakes.
