Description. Abeautifulspecieswithshinyblackbodyandbrightyellowlegs. Head 0.33 (0.31–0.34) mmlong, facialplatedefinitelyconvexinlateralview. Parafacialiavery narrow and with extremely thin white hairs. Posterior fronto-orbital very strong ( 0.175– 0.19 mm), anterior pair thin and only 0.08 mm. Frontal vitta shiny black. Interfrontal seta minute, only 2 (3) pairsmostanteriorly. Ocellar, outerandinnerverticalpairsstrong, occipitalsandpostocellarsnotdeveloped. Vibrissa 0.20–0.22 mmlong, peristomals 0.08 mm orshorter. Genalsetafine, 0.10 mm, severalshortgenalsetaealsodiscernible. Scapeminute, pedicellarge, longerthan 1stflagellomere, withawreathoflongapicalsetae, long- est one is the ventral one ( 0.11 mm, dorsal one 0.10 mm). First flagellomere more conical withadistinct (thoughnotsharp) dorsalapex. Aristaverylong, 0.74–0.79 mm, itscilia only 0.02 mmlong, orsomewhatless.

Acrostichals thin, notarrangedregularly, ca. 6–8 rowsanteriorly. Posterior kepst 0.20 mm, anteriorpair minute. Wing membrane light brown, veins (including C) ochre. Second / third costal sections: 0.70/0.54, ratio 1.3. Firstandsecondcostalsectionswithlongermarginalsetae ( 0.05 mm vs. 0.04 mm). R 4+5 terminates almost at wing tip. Inter-crossvein section of M 1+2, 0.20, M-M cross- vein 0.10 mm. Discal cell edgy, M 3+4 distinct on a distal section of 0.14–0.15 mm. Alulasmall, verynarrow, narrowlyroundedapicallywith 0.08–0.09 mmlongapicalhair. Halterwax-yellow. Legsentirelyyellow, exceptforforetibiaanddorsalapicalpartsof femora, withsomeobscurebrownishhue. Midtibiawithamoderatelylongantero-dorsal at 18/41 and at 33/41 each, a longer subdorsal at 14/41, a large subdorsal at 35/41, a pos- terodorsal seta at 33/41. Ventro-apical seta of mid tibia short and thick. Hind tibia with a 0.10–0.11 mmlongdorsalpreapicalseta.

Abdomen long, almost as long as head and thorax combined. Male sternite 5 (Fig. 66) medio-caudally with a long sagittal process, without short setae. The body of sternite 5 is withoutacombofflatblackspinebutwithsomelongsetae. Subepandrialsclerite (Fig. 67) ratherlargeanddark.
