Description. Female ( Fig. 42 View FIGURE 42 ). Body length 8.6 mm; fore wing length 7.0 mm.

Colour. Head, two basal antennomeres, thorax, coxae, trochanters and tibiae black with bronze-green metallic lustre. Flagellum and apices of hind tibiae up to preapical spurs black. Tibiae, tarsi, apex of femora and abdomen dark yellow. On abdomen basal half of tergite 1, small lateral spots on tergites 2, 4, 5, 8, and tergites 6–7 almost completely (only in middle with yellow area) black with slight blue metallic lustre. Mandibles dark brown, in middle reddish. Mouthparts light brown. Wings hyaline, veins brown, whitish at wing base and at base of pterostigma. Pubescence yellowish-white.

Head. Head behind eyes slightly expanded. Distance between eyes 1.4 × vertical diameter of eye; eye with vertical diameter 1.8 × its horizontal diameter. Postocellar area not convex, with week lateral furrows. POL: OCL: OOL as 1.3: 1.0: 1.2. Medial fovea broad, flat, only at upper part depressed, open towards frontal area. Lateral carinae short, blunt, indistinguishable already at level of antenna sockets. Supraclypeal area strongly roundly convex, smooth, shiny, rarely punctured and without median keel. Malar space slightly more than diameter of frontal ocellus. Clypeus smooth and sparsely punctured, with slightly rounded medial notch on ventral margin. Labrum straight on ventral margin.

Antennae. Antennal length 0.9 × maximum head width; flagellum weakly curved at base, widened towards apex, apex broadly rounded; its setae short, dense, closely adherent.

Thorax. Mesopleuron in lower part with glabrous band; scutellum slightly convex, broadly rounded at apex.

Legs. Middle and hind tibia with preapical spurs; tibial spurs simple. Basal tarsomeres of hind tarsus longer than next three combined.

Wings. In fore wing, cell 3Rs with anterior margin about equal to posterior margin, expanded to external margin. Vein 3r-m slightly curved. Vein B of fore wing joins vein R well before (longer than vein Sc) junction point of vein M. Membrane of cell 1Rs almost glabrous, with sparse short setae. Wing margin between veins M and Cu non ciliate, with glabrous band along margin.

Abdomen. Abdomen oblong, almost parallel. Tergites in basal half smooth, in apical part densely pubescent. Saw sheath 1.7 × as long as wide, simple, parallel-sided, bluntly rounded at apex (ventral view), on inner surface with small, blunt spines; in lateral view triangular, broadly rounded at apex, slightly concave in middle on ventral margin.

Lance in lateral view strongly convex, narrowed at base, uniformly covered with annuli almost to base. Maximum width of lance greater than 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 medially ventral margin. Annuli nearly straight and dorsally inclined towards apex, in apical part indistinct.Annular spines (ctenidia) short, simple, several times shorter than width of annulus. Ventral margin with 17 well-distinct, strongly sclerotised serrulae. Serrulae smooth, with only indistinct denticles. In apical third serrulae triangular, oblique, rounded at apex, rest of serrulae papillate, bluntly rounded. Between serrulae one short, straight pore canal of marginal sensilla.

Male ( Fig. 43 View FIGURE 43 ). Body length 8.0 mm; fore wing length 6.5 mm.

In colouration as female, but abdomen entirely dark yellow, hind tarsi darkened on dorsal side, flagellum with bronze-green metallic lustre. Head behind eyes slightly constricted. Distance between eyes 1.2 × vertical diameter of eye; eye with vertical diameter 1.6 × its horizontal diameter. POL: OCL: OOL as 1.5: 1.0: 1.3. Antennal length 1.3 × maximum head width; flagellum with long erect setae on anterior surface, apex narrowed. In fore wing, cell 3Rs longer in height than in length. Subgenital plate in ventral view with rounded posterior margin.

Genitalia as in Fig. 43j View FIGURE 43 , gonostipes broad, convex on inner margin, tapering towards apex. Harpe parallel at base, rounded at apex, elongated, length 1.5 × width at base, densely covered with tiny setae. Valve of penis with valviceps sickle-shaped, curved at apex dorsally, flat, bluntly rounded at apex. Valviceps in dorsal view narrow, linear, slightly broadened at base and at apex; in lateral view very narrow and curved, with large dorsal notch in middle, apex widened and bluntly rounded, with many large pores. Dorsal process (ergot) clearly visible, slightly curved.

Remark. The original description is based on 5 female and 2 male syntypes originating from “Kopet-Dagh, Firjuza” ( Turkmenistan, Kopet Dagh) (translated from Gussakovskij 1935: 417). Four females and two males were found in ZISP. The female is here designated as the lectotype.
