Description. Male (according to original description). Body length 6.5 mm, wingspan 15.0 mm.

“Almost not differentiated from female. On head lateral carinae of median furrow more acute at base. Third antennomere longer than head and thorax combined, vein 2m-cu falling just beyond inner corner of cell 3Rs. Genitalia are characterized by presence of protuberances on penis valva, from which it acquires shape of a boot.”

Female ( Fig. 46 View FIGURE 46 ). Body length 7.4–7.6 mm; fore wing length 7.5–7.6 mm.

Colour. Body black with metallic blue lustre. Flagellum, mouthparts, tibiae and tarsi dark brown. Hind tibiae in basal half yellowish-white. Wings transparent, in basal part, under pterostigma and in cell C indistinctly darkened. Pubescence silvery-white.

Head. Head behind eyes slightly expanded. Distance between eyes 1.4 × vertical diameter of eye; eye with vertical diameter 1.7 × its horizontal diameter. Postocellar area not convex, with weak lateral furrows. POL: OCL: OOL as 1.1: 1.0: 1.4. Medial fovea broad, flat in lower part, with weak rounded pit in upper part, wide open above to frontal area, below to supraclypeal area. Lateral carinae harp, curved, not joined together. Supraclypeal area smooth, shiny, evenly spaced punctuated. Malar space slightly larger than diameter of frontal ocellus. Clypeus smooth, shiny, sparsely punctate, slightly emarginated on ventral margin. Labrum flat on ventral margin.

Antennae. Antennal length 1.3 × maximum head width; flagellum weakly curved at base, widened towards apex, apex narrowly rounded; its setae short, dense, partially bent.

Thorax. Mesopleurae in lower part with glabrous band; scutellum flat, narrow rounded at apex.

Legs. Middle and hind tibia with preapical spurs; tibial spurs simple. Basal tarsomeres of hind tarsus about equal to next three combined.

Wings. In fore wing, cell 3Rs with anterior margin slightly longer than posterior margin, expanded to external margin. Vein 3r-m angularly curved. Veins B and M of fore wing join up at same point on vein R. Membrane of cell 1Rs densely covered with short setae. Wing margin between veins M and Cu non ciliate, without glabrous band along margin.

Abdomen. Abdomen oval (in dorsal view), tergites smooth at base, in apical part very densely punctured and pubescent. Saw sheath 1.5 × as long as wide, simple, parallel-sided, broadly rounded at apex (ventral view), on inner surface with small, blunt spines; in lateral view narrow, triangular, rounded at apex, almost straight on ventral margin.

Lance in lateral view slightly convex, distinctly narrowed towards apex, with sharp apex, medially with pronounced annuli. Maximum width of lance equal to lancet width. Carina of apical part of dorsal margin with finely, irregular and indistinct denticles, remaining part of dorsal margin with longitudinal shallow fossa. Lancet with straight dorsal and convex ventral margin.Annuli almost straight at base, curved in apical half, dorsally inclined towards apex. Annular spines (ctenidia) short, simple, several times shorter than width of annulus. Ventral margin with 17 unclear serrulae. Serrulae rounded, with small denticles, in apical third almost indistinguishable. Between serrulae two unequal, slightly curved pore canals of marginal sensilla.

Remark. The holotype (male) of this species was requested for study by Dr M.C. Wei ( China) a long time ago and was not returned up to now despite constant demands to return (S.V. Vasilenko, personal communication). The specimen is currently unavailable for study and its status is unknown. The characteristics of the male are provided in accordance with the original description.

Stroganova described the species by females, but designated the male as the holotype. There are discrepancies in the dates of specimens. Thus, on the label of the holotype the date 23.07.56 (date of larval collection) is indicated, while in the original description it is 29.07.56 (date of larval collection) and 2.04.57 (date of adult emergence). Below the text in the biology section it is stated that larvae were collected on 21, 29.07.56. Of the 6 larvae collected, 4 adult specimens emerged, and only three are labeled as type series.
