Description. Female ( Fig. 28 View FIGURE 28 ). Body length 8.8 mm; fore wing length 7.5 mm.

Colour. Head, thorax, two basal antennomeres, coxae, trochanters and femora, saw sheath black with light blue metallic lustre. Flagellum, mouthparts, fore tibiae and tarsi, apex of middle tibiae, apex of basal and remaining wholly of middle tarsomeres dark brown. Most part of middle and hind tibiae yellow. Apex of hind tibiae up to preapical spurs, hind tarsus black. Abdomen yellow-reddish. Wings uniformly darkened, brownish, under pterostigma with indistinct darker spot. Veins in basal half reddish, from pterostigma brown. Pterostigma dark brown. Pubescence yellowish-white.

Head. Head behind eyes slightly expanded. Distance between eyes 1.3 × vertical diameter of eye; eye with vertical diameter 1.8 × its horizontal diameter. Postocellar area convex, with weak lateral furrows. POL: OCL: OOL as 1.0: 1.2: 1.0. Medial fovea broad, triangular, flat, with weak rounded pit in upper part, open. Lateral carinae sharp, converging downwards, joining in long blunt but clearly defined keel median carina. Supraclypeal area convex, densely punctuated and wrinkled. Malar space nearly equal diameter of frontal ocellus. Clypeus smooth, shiny, sparsely punctate, with distinct medial semi-circular notch at half its width on ventral margin. Labrum with flat, weakly rounded ventral margin.

Antennae. Antennal length 1.4 × maximum head width; Flagellum weakly curved at base, narrow, apex narrowly rounded; its setae short, dense, closely adherent.

Thorax. Mesopleuron in lower part with glabrous band; scutellum slightly convex, narrowly 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 angularly curved. Veins B and M of fore wing join up at same point on vein R. Membrane of cell 1Rs densely covered with long setae. Wing margin between veins M and Cu ciliate, with sparse setae longer than width of vein M.

Abdomen. Abdomen oval (in dorsal view), to apex distinctly narrowed. Tergites in basal half shining, almost glabrous; in apical part pubescent. Saw sheath 1.7 × as long as wide, simple, parallel and widely rounded at apex (ventral view), on inner surface with long, blunt spines; in lateral view narrow, triangular, narrowly rounded at apex, slightly convex on ventral margin.

Lance in lateral view slightly convex, apex sharp, medially covered with annuli. Maximum width of lance equal to lancet width. Carina of apical part of dorsal margin well defined, with indistinct irregular denticles, remaining part of dorsal margin with longitudinal deeply fossa. Lancet with straight dorsal and convex ventral margin. Annuli almost straight, slightly inclined towards apex, in apical part indistinct. Annular spines (ctenidia) short, simple, several times shorter than width of annulus. Ventral margin with 18 well-distinct serrulae, barely distinguishable at apex. Serrulae almost smooth, with only indistinct denticles. Serrulae triangular, in apical half with unequal sides, oblique. Between serrulae two unequal, straight pore canals of marginal sensilla.

Male ( Fig. 29 View FIGURE 29 ). Body length 7.6 mm; fore wing length 6.5 mm.

In colouration as female, but tibiae yellow, two basal tarsomeres on fore and middle tarsi, and base of first tarsomeres of hind tarsus yellow. Head with blue-green metallic lustre. Sternites and apical tergites of abdomen dark reddish, other tergites brown with blue-violet metallic lustre. Lateral keels parallel. Distance between eyes 1.2 × vertical diameter of eye; eye with vertical diameter 1.8 × its horizontal diameter. POL as OCL as OOL. Antennal length 2.2 × maximum head width; Flagellum with long erect setae on anterior surface. Subgenital plate in ventral view with flat posterior margin.

Genitalia as in Fig. 29j View FIGURE 29 , gonostipes broad, convex on inner margin, tapering towards apex. Harpe parallel at base, narrowed at apex, elongated, little longer than width, evenly covered with dense fine setae. Valve of penis narrow, arrow-shaped, pointed at apex. Valviceps in dorsal view elongate, apex triangular, acute, with rounded lateral lobe directed backwards from apex, with small notch in medial part; in lateral view dorsally slightly concave, apex acute, triangular, strongly sclerotised, with many pores and scale-like sculpture on lateral surface of lateral lobe, ventrally slightly convex at base. Dorsal process (ergot) barely noticeable.

Remark. The original description is based on one female and two male syntypes originating from “Tularud” ( Iran, Tula Rud-e Bala) (translated from Gussakovskij 1935: 409). One female and two males were found in ZISP. The female from Tula Rud-e Bala is here designated as the lectotype.
