Additional material.

3 ♀ (MTMA, NMS, RMNH), " Mongolia: Südgobi aimak, Somon Bulgan, Talyn bulag, 1350 m, Exp. Dr. Z. Kaszab, 1967", "Nr. 889, 5.vii.1967", " Rogas fahringeri Tel., ♀, det. Papp, 1976"; 1 ♀ (RMNH, ZJUH), " China: Ningxia, Yinchuan, 6.vii.1983, no. 840994, Xu Wenzhong, RMNH’99”.

Molecular data.

None.

Biology.

Unknown. Specimens have been collected in June-August. Presumed to be univoltine, but we have not seen reared material and the means of overwintering is unclear.

Diagnosis.

Maximum width of hypoclypeal depression 0.6-0.7 × minimum width of face; OOL 0.9 × diameter of posterior ocellus, largely smooth with spaced punctures; ventral margin of clypeus thin, anterior part shiny and distinctly protruding anteriorly (Fig. 320 ); mesoscutum shiny and moderately punctulate; precoxal area with only some rugulae medially; vein r of fore wing 0.5-0.6 × as long as vein 3-SR; tarsal claws rather slender and with yellowish or brown pecten, pecten remains removed from apical tooth (Fig. 321 ); hind tarsus fairly elongate and segment with medium-sized apical spines (Figs 307 , 321 ); pterostigma brownish yellow; wings subhyaline; head and mesosoma laterally and dorsally (except more or less dark brown propodeum) yellowish brown; fore wing longer than 5 mm.

Description.

Redescribed ♀ (RMNH) from Mongolia (Somon Bulgan). Length of fore wing 6.9 mm, of body 7.7 mm.

Head. Antennal segments of ♀ 58, length of antenna 1.1 × fore wing, its basal and subapical segments slender (Figs 316 , 317 ); frons largely smooth anteriorly and rugulose posteriorly; OOL 0.9 × diameter of posterior ocellus, largely smooth with spaced punctures, (but superficially coriaceous near eye) and with satin sheen; vertex largely smooth, but superficially rugulose behind ocelli; anterior part of clypeus nearly 5 × wider than long, medially distinctly wider than laterally, largely smooth, punctulate, its ventral margin thin and protruding forwards (Fig. 320 ); width of hypoclypeal depression 0.7 × minimum width of face (Fig. 318 ); length of eye 1.6 × temple in dorsal view (Fig. 319 ); clypeus near lower level of eyes; length of malar space 0.2 × length of eye in lateral view.

Mesosoma. Pronotum medio-dorsally flat, shiny and largely smooth; mesoscutal lobes largely smooth except for punctulation, shiny and densely setose; precoxal area of mesopleuron largely smooth medially, with only some superficial rugulae; remainder of mesopleuron finely punctate and antero-dorsally rugose; metapleuron remotely punctate and largely smooth medially; scutellum remotely punctulate; metanotum with fine complete median carina; propodeum weakly convex and densely rugose, its medio-longitudinal carina complete and fine.

Wings. Fore wing: r 0.5 × 3-SR (Fig. 310 ); 1-CU1 horizontal, 0.3 × 2-CU1; r-m 0.7 × 3-SR; 2nd submarginal cell medium-sized (Fig. 310 ); cu-a inclivous, straight; 1-M nearly straight posteriorly; 1-SR somewhat widened; surroundings of M+CU1, 1-M and 1-CU1 evenly setose but setae pale and easily overlooked. Hind wing: marginal cell linearly widened, its apical width 2.4 × width at level of hamuli (Fig. 310 ); 2-SC+R short and longitudinal; m-cu vaguely indicated; M+CU:1-M = 10:7; 1r-m 0.8 × 1-M.

Legs. Tarsal claws with rather inconspicuous and pale brownish pecten remaining far removed from apical tooth (Fig. 321 ); hind coxa largely superficially finely punctate, but dorso-anteriorly densely punctate; hind trochantellus rather robust; length of hind femur and basitarsus 4.4 and 6.0 × their width, respectively; length of inner hind spur 0.5 × hind basitarsus.

Metasoma. First tergite rather flat, 1.1 × as long as wide apically; 1st and 2nd tergites with fine medio-longitudinal carina and finely longitudinally (1st) or irregularly (2nd) densely rugose; medio-basal area of 2nd tergite triangular and medium-sized (Fig. 313 ); 2nd suture rather deep, finely crenulate and narrow; basal half of 3rd tergite finely rugulose, remainder of metasoma superficially micro-sculptured or nearly smooth; 4th and apical half of 3rd tergite without sharp lateral crease; ovipositor sheath wide, with medium-sized setae and apically truncate (Fig. 308 ).

Colour. Yellowish brown; antenna (except dark brown scapus and pedicellus), stemmaticum and ovipositor sheath black; tarsi, medio-posterior patch of propodeum, basal patch of 1st tergite and apex of hind tibia dark brown; veins rather dark brown at medial third of fore wing, remainder of veins pale brown or yellowish; pterostigma brownish yellow; wing membrane subhyaline.

Variation. Scapus entirely dark brown or largely yellowish brown; dark patches of propodeum and 1st tergite sometimes absent (♀ RMNH from Ningxia). Antennal segments: ♀ 56(2), 58(2), 59(1); ♂ 57(1), 59(1). Male is very similar with apical tergites type?1-2, setae short, sparse and hard to see, with fringe very short and negligible.

Distribution.

China (Ningxia), Mongolia.

Notes.

This Asian species is included here because it was reported from Poland (Huflejt, 1997). The record needs confirmation to rule out confusion with a similar European species.
