Redescription. Colour. Black. Frontal vitta and fronto-orbital plate black; face, parafacial, antenna and gena black with grey-brownish pruinosity; palpus black; mesonotum metallic black with one silver-dusted central vitta along presutural acrostichals, pleura silver pruinose; postpronotal lobe silver pruinose; notopleuron silver or grey pruinose; legs black; haltere yellow; calypters brownish, upper calypter with brownish edge and on outer half white and opaque; wing without dark markings; abdomen black but last tergite and ventrally with silver pruinosity.
Male. Body length: 7.0–8.0 mm; wing length: 6.0 mm.
Head. Eyes bare but with the usual minute and scattered hairs, separated at level of anterior ocellus by 0.20– 0.22 of head width, frons divergent towards lunule; ocellar triangle with 4–5 pairs of setae; 14–16 pairs of frontal setae; pedicel with 2 setae and a few setulae; arista plumose, with 16–22 cilia, bare apicad, and with some secondary plumes as far as level of 5th to 6th cilia; vibrissa as long as arista; 1 strong supravibrissal seta, half as long as vibrissa, and many other setulae that extend to basal fourth level of postpedicel; 4–5 subvibrissal setae followed by 9–10 genal setae.
Thorax. Acrostichals 0+2, the first pair weaker; dorsocentrals 3+4; intra-alars 1+1; presutural 1; prealar 1, half the length of first supra-alar; supra-alars 2; postpronotals 4, the innermost weaker; notopleuron with 2 long, subequal setae and covered with ground-setulae; postalars 2; intrapostalar 1; scutellum with 1 basal, 2 discal and 1 apical pairs of setae, and latero-ventrally with many setae, the basalmost ones downcurved; postalar wall bare; suprasquamal ridge with short pile; proepisternal depression bare; proepimeron with about 5 long setae and a few long setulae; prosternum broad and setulose; anepisternum with a posterior row of about 9 setae, with 3–4 weak setae upcurved on upper-anterior corner, and covered with long setulae; katepisternals 1+2; anepimeron extensively setulose; katepimeron with 1 setula; anatergite bare; katatergite setulose. Legs: fore femur with a posterodorsal row of setae on apical two-thirds becoming shorter basad, and a complete posteroventral row of setae; fore tibia with an anterodorsal row of short and strong setae, a row of strong and very short dorsal setulae, 2– 3 long posteroventral setulae on middle third, many setulae on ventral surface, 1 anteroventral, 1 dorsal, 1 posteroventral and 1 ventral preapical setae, and anterior surface with a brush-like ctenidium of golden setulae; fore tarsus with a golden ctenidium and with some long setae on basal segment; mid femur without a tubercle, with 5–6 ventral setae on basal half, 1 anterior seta at middle third, and 3–4 posterodorsal to posterior preapical setae; mid tibia with an anterodorsal row of very short setae, 3–4 short setae on apical half, 3 strong posterior setae on middle third, a posteroventral row of 4–5 strong setae on basal two-thirds, 1 anterodorsal, 1 dorsal and preapical setae, and 2 anteroventral and 2 ventral apical setae; hind femur with an anteroventral row of setae, strongest on apical third, an anterodorsal row of setae, a ventral row of weak setae on basal half, 2 posterodorsal preapical setae and a few posteroventral setulae on apical fourth; hind tibia with 5–6 subequal anteroventral setae on apical half, an anterodorsal row of short setae of which 2 at middle are longer, a dorsal row of short but strong setulae, a posterior row of weak setae, a long and strong posterodorsal seta on apical third, some long posteroventral to ventral setae on apical half, the basalmost ones longer, 1 anterodorsal, 1 dorsal, 1 anteroventral preapical setae, 1 anteroventral and no posteroventral apical setae, and a posterior brush-like golden ctenidium; hind tarsus with a golden brush ventrally. Wing with a uniform covering of microtrichia; dm-cu sinuous; stem-vein bare on dorsal surface, and ventrally with about 3–5 short setulae before humeral cross-vein and bare after humeral cross-vein; R2+3 bare on dorsal and ventral surfaces; R4+5 setulose from base to midway to r-m on dorsal surface and at base on ventral surface; 5–6 strong setae on basicosta.
Abdomen. With a lateral tuft of setulae on syntergite 1+2; tergites 3–5 with setae laterally; tergite 4 with setae apically and tergite 5 with a few discal setae; sternite 1 setulose; posterior margin of sternite 5 concave and with setae on membrane (Fig. 144).
Terminalia. Outer margin of cercal plate slightly convex; cercal plate ventrally with one strong spine (Figs 145–147); surstylus with 3 setae basally; aedeagus with spicules on anterior membrane of distiphallus; gonopod with 2 setae on basal half; paramere with a few setulae on apical half (Fig. 148).
Female. Body length: 6.0–7.0 mm; wing length: 6.0–7.0 mm.
Similar to male, differing as follows: calypters yellowish; eyes separated at level of anterior ocellus by about 0.34–0.40 of head width; fronto-orbital plate with 2 proclinate setae, 5 proclinate setulae and 1–2 reclinate setulae; fore tibia without long posteroventral setulae; hind tibia without a row of setae but with 2 posterodorsal setae, 1 on basal third and another on middle third, and without setae on posteroventral to ventral surfaces.
