(Fig. 4)
Diagnosis. Frons with short setae between eyes; antenna with postpedicel entirely black; mesonotum with 5–7 acrostichals and 5 strong dorsocentrals on posterior third; katepisternum entirely covered with numerous setae; femora yellow; fore tibia with thick, golden-brown apical spines.
Description. Female (Fig. 4A). Body length 5.3 mm; wing 3.9 x 1.2 mm; antenna 0.6 mm. Head (Fig. 4B; partly covered with crystallized salt). Postcranium, vertex, frons and face dark blue-green, covered with grey pruinosity; head (excluding proboscis) slightly wider than high in anterior view; all setae white; postoculars forming single row of setae around posterior orbit; lower postoculars short; ventral postcranium with many sparse setae; frons with additional short setae between eyes; clypeus wider than face (52/40) and distinctly tectiform, covered with numerous long white setae; palpus elongate-ovate, mostly brown, yellow at apex, with grey pruinosity and yellow setae; proboscis brown-black and rather stout; antenna (Fig. 4C) with scape and pedicel mostly yellow, scape black at extreme base, pedicel brownish dorsally, postpedicel entirely black; pedicel simple, with corona of short white setae; postpedicel trapezoidal, bare, appearing bi-segmented, slightly longer than high at base (0.23/ 0.18 mm); basal part of postpedicel covering apical part dorsally with narrow process; apical part of postpedicel subtriangular (median view); arista-like stylus shorter than postpedicel, with two articles, apical, shortly pubescent; length (mm) of scape, pedicel, postpedicel, stylus (articles 1 and 2), 0.15/0.06/0.23/0.06/0.09. Thorax. Mesonotum, scutellum and pleura dark bluish green, covered with grey pruinosity; all setae white; mesonotum with 5–7 acrostichals on posterior 1/3, decreasing in size anteriorly; 5 strong dorsocentrals on posterior 1/3, greatly decreasing in size anteriorly; rest of mesonotum covered irregularly with numerous short setae (Fig. 4F); scutellum with 2 pairs of strong marginal bristles and many setae dorsally, more than half as long as major setae; proepisternum and katepisternum entirely covered with numerous setae, longer on lower part of proepisternum; notopleuron with additional short setae. Legs. Coxae mostly greenish black, yellow at apex; legs yellow with femora and last tarsomeres orange yellow, tibiae and basitarsi light yellow; legs including fore and mid coxae densely covered with white setae, without black vestiture; fore coxa without strong bristles; hind coxa with several white lateral setae, without bristle; fore femur (Fig. 4D) strongly swollen, with irregular anteroventral and posteroventral rows of very short brown bristles in apical half; fore tibia gradually swollen distally, with 1 anterior and 2 posterior thick golden-brown apical spines, reaching mid-length of basitarsus; fore tarsomeres with only short white apical setae; fore tarsomere 5 with large pulvilli and strongly curved claws; mid femur not swollen, with 2–5 anterodorsal bristles In apical half; mid tibia (Fig. 4E) with 3 anterodorsal, 3 posterodorsal, 1 anteroventral, 2 posteroventral, 4 short apical and 1 very long apicoventral bristles; all bristles light brown; mid tarsomeres with a few short light apical setae; tarsomere 5 with white pulvilli and black claws; hind femur slightly swollen and curved, with 3 white dorsal bristles in middle; hind tibia simple, with 3 anterodorsal, 3 posterodorsal, 1 ventral, 4 apical bristles; hind tarsus simple, with white pulvilli and black claws; femur, tibia and tarsomere (from first to fifth) lengths (mm): fore leg: 1.17/0.98/0.31/0.12/0.1/0.1/0.2, mid leg: 1.09/1.28/0.83/0.29/0.19/0.14/0.17, hind leg: 1.95/1.47/0.66/0.25/0.17/0.17/0.2. Wing (Fig. 4G). Hyaline, veins yellow; costa with mainly black setulae, with white setulae at base; R 1 slightly thickened, long, reaching costa behind mid length of wing; lengths of parts of costa between R 2+3 and R 4+5 versus between R 4+5 and M 1 (in mm), 0.42/0.18; crossvein dm-m straight; length of dm-m to apical part of M 4, 0.28/0.47; anal lobe wide; anal angle acute; lower calypter yellow, with whitish cilia; halter pale yellow. Abdomen (Fig. 4A). Tergites 1–5 wide and rounded, mostly shiny blackish green, with weak pruinosity; tergites covered with short white vestiture and each with row of white bristles near tergal margins; sternites 2–4 well developed, blackish green, with longitudinal median suture and short setae; sternite 5 entire; other segments retracted; terga 9+10 divided medially into two hemitergites, each bearing 6 thick spines (Fig. 4H); cercus brown, elongate-ovate, with a few long white setae.
