Male

Head. Third antennal segment acuminate; yellow. Face silvery pollinose. Frons, upper part shining brown, lower part silvery pollinose; eyes touching for distance equal to 1.5 times ocellar triangle. Occiput slightly greyish pollinose.

Thorax. Humeri black. Mesonotum (viewed obliquely from front) probably greyish pollinose (surface greasy); similarly on the side. Scutellum greyish pollinose, almost bare, only some weakly developed pale hairs. Dorsocentral hairs very weakly developed. Halter yellow, base brown.

Legs. Trochanters amber coloured, base of femora yellow, femora brown, knees and tibiae yellow. Third trochanter with long projection, f3 thickened and bent, hind tibia bent in the middle. Tarsal segments yellow, last segment brown. Ventroapical row of 3–6 weak spines on first four femora; no spines on 3rd femur, only some whitish hairs. Subapical (distal) spines on first four tibiae present. No anteromedial hairs on 3rd tibia. Hind trochanter with short whitish hairs on ventral side. Pulvilli slightly longer than last tarsal segment.

Wing. Fourth costal section 1.2 times as long as third costal section. Cross-vein R-M at 1/3 of discal cell. Pterostigma almost fully coloured. Hairs on tegula absent.

Abdomen. Viewed obliquely from front tergites brownish pollinose, sides more silvery pollinose. Hairs missing, 2 dark lateral spines on first tergite. Postabdomen in dorsal view: S7 visible; T5 0.7 times as long as ST8. Genitalia without dissection: ST8 swollen, no m.a., EP and SS yellow and small compared to ST8.

Genitalia. Surstyli subsymmetrical, their inner projection in long; epandrium small, slightly asymmetrical; ST8 very large, without m.a. (Fig. 21D). The borders of SES are not clear, with a patch of hairs on the left and dispersed hairs on the right; gonopods flat and rounded; phallic guide with hook-like projection on the left in ventral view ( Fig. 21E View FIGURE 21 ), membranous ventrally, with minute hairs dorsally; phallus trifid, splitting only on distal part, apices pointed ( Fig. 21A View FIGURE 21 ); ejaculatory apodeme parachute-shaped, with 3 lobes; sperm pump with 3 appendages ( Figs 21B, F View FIGURE 21 ).

Female

As male except for the following characters. Frons, eyes separated; silver-grey pollinose except in front of ocellar triangle for length equal to 2–3 times ocellar triangle, colour-change continuous. Humeri yellow-brown, femora not thickened, trochanters without projection, t3 slightly bent. Pulvilli and claws about 1.5 times as long as last tarsal segment. Abdomen golden-brown pollinose, slightly greyish laterally. Dispersed whitish hairs on segments. Female ovipositor as in Figs 40H–I View FIGURE 40 .
