Diagnosis. Frons yellow except for area around insertion of antennae brown; face brown with an inverted Wshaped yellow spot; scape dark brown; pedicel dark brown with whitish-yellow dorsoapical spot; first flagellomere pale yellow; palpus brown; scutum brown with postpronotal lobe and postero-lateral margin slightly paler; scutellum yellow; legs yellow except basal ¾ of fore tibia brown, base and apex mid of hind tibiae brown, tarsi whitishyellow with basal half of first tarsomere of fore tarsus brown.

Description. Holotype male. Body: 3.6 mm. Wing: 3.3 mm. Thorax: 1.5 mm. Head ( Fig. 64 View FIGURES 62 – 71 ). Frons yellow except for area around insertion of antennae brown. Face brown with an inverted W-shaped yellow spot and fine yellow setae. Parafacial yellow. Gena yellow with dense whitish microtomentum and conspicuous long thin yellow setae. Antenna: scape dark brown; pedicel dark brown with whitish-yellow dorsoapical spot; first flagellomere whitish-yellow, long-oval; arista sub-basal dorsal, yellow basally and brown on the remaining part, 13 dorsal and 4 ventral long brown rays. Mouthparts: proboscis pale brown with diffuse yellow spots; palpus brown, at least 3 times longer than wide, with short black setulae; clypeus bulged, yellow with brown borders. Postcranium brown above foramen, yellow below, laterally and on upper margin, with sparse whitish microtomentum and a band of dense whitish microtomentum on lateral margin of eye; setae sparse, yellow, short and thin. Eyes with interfacetal setae somewhat numerous, conspicuous. Setae: 1 medial and 1 lateral elongate vertical pair of the same length, 1 short orbital pair inserted slightly above middle of frons, all yellow; 1 postocellar pair, shorter, divergent and brown; ocellar pair not differentiated.

Thorax brown with postpronotal lobe and posterolateral margin slightly paler, with dense, short yellow coating setulae, lateral and postero-lateral margins with dense yellow microtomentum. Scutellum yellow with dense yellow microtomentum. Pleurae with scattered yellow microtomentum except for a shiny bare area that extends from anepisternum to katepisternum. Setae: 1 postpronotal and 2 notopleural, both short; 1 postsutural supra-alar, 1 postalar and 1 dorsocentral prescutellar, all elongate; all setae brown; 2 pairs of long yellow scutellar setae; 1 strong black katepisternal seta on upper margin plus some fine yellow setae below; scutellar setae yellow, fine setae on katepisternum yellow, and remaining setae brown.

Legs yellow except for: basal ¾ of fore tibia brown, base and apex of mid and hind tibiae brown, tarsi whitishyellow with basal half of first tarsomere of fore tarsus brown. Femora with antero- and posteroventral series of black spine-like setae, larger and more conspicuous on fore femur; mid tarsus with small black apical spines on ventral surface of tarsomeres 1–4. Apicoventral spine of midtibia very short, inconspicuous.

Wing ( Fig. 53 View FIGURES 51 – 58 ) brown, pale brown on margins; longitudinal fold crosses dm-cu in the middle.

Abdomen brown with dense yellow microtomentum; setae very weak, short, yellow and scattered. Tergite 1+2 divided longitudinally by unsclerotized median line on basal half; sternites sclerotized, small, sternite 6 with deep quadrangular cleft on distal margin ( Fig. 14 View FIGURES 7 – 15 ); tergite 6 free from syntergosternite 7+8. Terminalia: phallus short, membranous ( Fig. 12 View FIGURES 7 – 15 ); cercus large with rounded inner protuberance near base ( Fig. 11 View FIGURES 7 – 15 ); postgonites long, upcurved posteriorly, with dorsal projection near base; ejaculatory apodeme as in Figure 13 View FIGURES 7 – 15 .

Female. As in the male except for: first tarsomere of fore tarsus wholly yellow. Terminalia ( Fig. 15 View FIGURES 7 – 15 ): syntergosternite 7 slightly widened, strongly sclerotized; sternite 8 pentagonal with deep incision posteriorly ( Fig. 15 View FIGURES 7 – 15 ); cercus small.
