(Figs. 41–45, 59, 72)
Diagnosis. Head triangular in frontal view; frons shiny brown; face shiny yellow; antenna yellow; palpus brown; scutum and scutellum brown, postpronotal lobe pale brown; legs brown except apexes of tibiae pale yellow and tarsi whitish-yellow; fore femur with slender elongate setae on postero-ventral surface; surstylus elongate, articulated with hypandrium; female hypoproct small, ellipsoid.
Description. Holotype male. Body: 1.5 mm. Wing: 1.3. Thorax: 0.65. Head (Fig. 72). Frons shiny brown. Face shiny yellow, with elongate, thin yellow setae. Parafacial pale brown. Gena yellow, with short yellow setae. Antenna yellow; pedicel with few short brown setae; first flagellomere oval-elongate; arista sub-basal dorsal, yellow basally and dark brown distally, with 6 dorsal and 3 ventral brown rays. Mouthparts: proboscis yellow; palpus dark brown, short, clavate, with rounded apex and thin brown setae; clypeus dark yellow, U-shaped. Postcranium brown, paler on lateral margin, with band of dense whitish microtomentum on lateral margin of eye, and fine brown setae on lateral margin and postgena. Eyes with very short and fine, sparse, pale interfacetal setae. Setae: 1 lateral vertical and 1 medial vertical pairs long but medial pair twice longer than lateral pair; 1 orbital pair inserted below middle of frons, as long as lateral vertical pair; 1 short, divergent postocellar pair; 1 ocellar pair directed downward, convergent, fine, elongate, longer than postocellar pair, inserted laterally on ocellar triangle; all setae pale brown.
Thorax shiny brown with pale brown post-pronotal lobe, very fine, sparse pale brown microtomentum on notopleuron and mesopleuron, except anepisternum and katepisternum with anterior part without microtomentum. Scutum covered by short pale brown setulae. Setae: 1 postpronotal; 2 notopleural; 1 post-sutural supra-alar; 1 postalar; 1 dorsocentral prescutellar very long; katepisternum with 2 developed setae on upper margin and a few more short setulae on lower margin; 2 scutellar pairs as long as dorsocentral prescutellar, apical pair convergent; all setae brown.
Legs predominantly brown, tibiae with pale yellow apexes and tarsi whitish-yellow. Fore femur with slender elongate setae on postero-ventral surface, shortened on mid and hind femora; mid tarsus with small ventral apical brown spines on tarsomeres 1-3. Apicoventral spine of mid tibia pale brown reaching midlength of basal tarsomere.
Wing (Fig. 59) brown on basal portion and slightly paler apically; the longitudinal fold crosses the vein dm-cu above the middle.
Abdomen brown with coating setae short, thin and yellow. Tergites 1+2 about 1/3 of length of abdomen, divided longitudinally by an unsclerotized median line on basal half; sternite 6 concave anteriorly (Fig. 44); tergite 6 and syntergosternite 7+8 fused laterally. Terminalia: phallus short, slender (Fig. 42); cercus small, membranous, widely separated (Fig. 41); postgonites short (Figs. 41, 43); surstylus elongate, discrete, articulated with hypandrium (Figs. 41, 42); ejaculatory apodeme small.
Female. As in the male. Terminalia (Fig. 45): syntergosternite 7 well sclerotized; sternite 8 rather triangular; hypoproct small, ellipsoid; cercus small.
