Hoplisoides leleji Mokrousov sp. nov. Figures 3A-H , 4A-E , 7A-B Material examined. Holotype , ♀ : Turkmeniya / 5 km S Firyuzy / Lelei 24.V.90 [ Turkmenistan , 5 km N Firjuza , 37°57'N , 58°06'E , 24.V.1990 , leg. A.S. Lelej ] // Holotype ♀ / Hoplisoides leleji / Mokrousov [ZISP]. Paratypes : 1♀ , 1♂ with same data as holotype [ ♀ in FSCV, ♂ in ZISP] . Diagnosis. Acetabular carina reaching omaulus, omaulus-sternaulus at junction with acetabular carina curved; female Head ratio H:W = 0.77; POL:OOL = 1.09; male head ratio H:W = 0.80; POL:OOL = 1.37; punctation of metanotum and propodeal dorsolateral surface with irregular punctures, with distinct smooth interspaces. More related to H. latifrons Spinola, differs by more space punctation of propodeum (coarse on H. latifrons ); omaulus-sternaulus at junction with acetabular carina distinctly curved (not curved at H. latifrons ). Female differs also: tentorial pit situated distinctly closer to antennal socket at frontoclypeal suture between eye and antennal socket (nearly at middle at H. latifrons ); flagellomeres shorter, F1 L/W = 1.81, F9 cubelike (F1 L/W = 2.42, F9 elongate at H. latifrons ); mid tarsomeres more robust. Male differs also: tentorial pit situated about middle at frontoclypeal suture between eye and antennal socket (distinctly closer to eye on H. latifrons ); flagellomeres shorter, F1 L/W = 1.23, F10 slightly longer than wide (F1 L/W ca. 1.5, F 10 distinctly longer than wide on H. latifrons ), antennal tyloids weaker developed, on basal flagellomeres very short (distinct on H. latifrons ). Morphological differences from all Palaearctic species given in key. Description. Female . Body length 9.6-10.6 mm (holotype 9.6 mm); fore wing length of holotype 7.2 mm. Head (Figs 3C-D ). Head ratio H:W = 0.77; POL:OOL = 1.09; eyes slightly convergent downwards. Frons above antennal sockets without longitudinal elevation (carina). Occipital carina well developed; it does not reach hypostomal carina at distance larger than diameter of anterior ocellus. Tentorial pit situated distinctly closer to antennal socket at frontoclypeal suture between eye and antennal socket (Fig. 3F ); flagellomeres shorter, F1 L/W = 1.81, F9 cubelike. Punctures deep, but scattered on frons (from below with several punctures only), clypeus and back side of head, more dense on vertex. Mesosoma (Fig. 3H ). Acetabular carina reaching omaulus, omaulus-sternaulus at junction with acetabular carina curved. No subomaulus. Metapostnotum well separated, with weak medial furrow and lateral folds diverging to posteriorly. Propodeal slope with strong median keel and irregular adjoining sculpture or transverse rugae. Punctation on pronotal collar and scutellum small and sparse; on mesonotum irregular, deep, but sparse; mesopleuron and sides of propodeum punctation sparse, with large smooth interspaces; dorsolateral parts of propodeum irregular punctured, with noticeable smooth interspaces. Wings (Fig. 3E ). Venation typical for genus; hindwing media diverging at cu-a. Legs. Foretarsal rake well developed, basitarsus with three rake setae before apex. Metasoma. T1 not elongate, approximately as long as width. Pygidial plate broad, sharply edged, with elongated little smoothed punctures. Punctation of T1 irregular, dense at base and sparse posteriorly; T2 with large, T3-T5 with smaller irregular punctures; S2 with large S3-S6 with smaller scattered punctures. Coloration (Fig. 3A ). Black and brown with rich yellow pattern. Yellow are: clypeus (except apical border), spot laterally of antennal socket and large spot along inner edge of eye, narrow strip at posterior margin of eye; scape and pedicel from below; pronotal collar and lobes, small spot on mesonotum near axilla, scutellum, large spot on mesopleuron, lateral large propodeal spot; metanotum on holotype marked yellow (black on paratype); wide apical bands on T1-T5 (T5 predominantly yellow) and apicolateral spot on S2. Apical border of clypeus, labrum, middle part of mandibula and basal flagellomeres from bellow brownish. Fore- and mid legs yellow with black coxae, trochanters, base of femora and apicoposterior spot on tibiae. Hind coxa and trochanter black; hindfemur and hindtibia posteriorly, hind tarsus completely brownish. Forewing with darkened area on radial cell, submarginal cell II and anterior part of submarginal cell III. Setation ill developed; head along inner edges of eyes and lateral parts of clypeus without silvery pubescence. Stout setae on clypeus, labrum and mandibles. Figure 3.

Male . Body length 8.0 mm. Head (Figs 4B-E ). Head ratio H:W = 0.80; POL:OOL = 1.37; eyes distinctly convergent downwards. Frons above antennal sockets without longitudinal elevation (carina). Occipital carina well developed; almost reaches hypostomal carina. Hypostomal carina near end of occipital carina with distinct lamellar elevation. Tentorial pit situated about middle at frontoclypeal suture between eye and antennal socket (Fig. 4B ). Clypeal lateral brush present, thin. Flagellomeres short, F1 L/W = 1.23, F10 slightly longer than wide. Antennal tyloids on F1-F9 thin; on F10 developed at base only; on F10 lacking. Punctation as at female. Mesosoma and wings as at female. Legs. Foretarsal rake poorly developed, tarsal rake spines short. Basal midtarsomeres symmetrical, not modified; apicoposterior spine on hind tarsomeres not longer than apicoanterior spine. Metasoma. Seven normally visible terga. Punctation similar to female. Coloration. Similar to female, but stripe along inner edge of eye reaches to clypeus; supraclypeal sclerite, mandibles (except apex), midcoxa apically, hind coxa and hind trochanters predominantly, hind tarsus with yellow pattern. Anterolateral spots on S2 large, brown spot on foretibia small. Antenna completely dark. Setation similar to female. Figure 4. Hoplisoides leleji Mokrousov, sp. nov., male, paratype: A habitus, lateral view B tentorial pit and adjacent area, frontal view C antenna, dorsal view D head, frontal view E head, dorsal view. Etymology. The species is named after famous Russian entomologist Arkady S. Lelej (FSCV), who collected the type series of the new species. Distribution. Turkmenistan. Figure 5.
