DIAGNOSIS

Suspensorium with pair of narrow stick-shaped processes ( Fig.3A View FIG [ssp]).Ventral phallobase lobe large and long, narrowing to its apex ( Fig. 3B View FIG [vlphb]). Each dorso-lateral phallobase lobe with nearly semicircular process basally ( Fig. 3A View FIG [bpphb] and with one long narrow and one small hook-shaped subapical processes ( Fig. 3A View FIG [spphb]). First metatarsomere with six intermediate apical spines.

DESCRIPTION

Total length (from the apex of clypeal proboscis to the apex of fore wing): male – 4.1 mm.

Hind wings with basal cell large, oval ( Fig. 2 View FIG ). Sc + R 2, M 4, CuA 2, CuP 1, Pcu 1. Sc + R furcates in apical half of the wing, branches short. Between radius and median there are several secondary veins forming two triangular cells. Median firstly furcates near to wing middle, and again – in apical half of the wing. Posterior branch of median (M 4) zigzag-shaped. Cubitus anterior furcates near to wing middle. Anterior branch of CuA (CuA 1) zigzag-shaped.

General coloration of upper side brown to dark brown ( Fig. 1 View FIG A-C). Genae under the eyes, scapus and pedicel, and postclypeus dark brown. Anteclypeus and trochanters of the legs light yellow. Fore wings brown with some veins white. Hind wings light brown. Abdominal sternites light brown, with yellow greenish spots. Fore and middle femora dark brown. Fore and middle tibiae dark brown, with light brown apices. Hind femora brown. Hind tibiae light yellow brownish. Tarsi brown. Apices of spines black.

Male genitalia

Pygofer narrowing from its base to its apex under the anal tube (in lateral view), with distinctly convex hind margin ( Fig. 3A View FIG ). Anal tube wide and short, widening apically (in dorsal view) ( Fig. 3E View FIG ), lateral margins turned down (in lateral view) ( Fig. 3A View FIG ). Anal column (paraproct) long, ½ as long as anal tube. Suspensorium with pair of narrow stick-shaped processes ( Fig.3A View FIG [ssp]) which are apparently fixed by the basal lobes of the phallobase ( Fig. 3A View FIG [bpphb]). Phallobase curved at almost right angle (in lateral view).Ventral phallobase lobe large and long, narrowing to its apex ( Fig. 3B View FIG [vlphb]). Each dorso-lateral phallobase lobe with nearly semicircular process basally ( Fig.3A View FIG [bpphb]) above the suspensorium process and with one long narrow and one small hook-shaped subapical processes ( Fig. 3A View FIG [spphb]). Phallobase membranous dorsally. Aedeagus with pair of long and narrow ventral hooks which arising basally and directed to the apex of phallobase ( Fig. 3A, B View FIG [vh]). Style with massive plate and rounded caudo-dorsal angle ( Fig. 3C View FIG ); capitulum on distinct neck, wide, slightly narrowing apically (in dorsal view) ( Fig.3D View FIG ); apical tooth small, lateral tooth well developed.
