Male. Body length: 5.0– 5.5 mm; wing length: 5.0–6.0 mm.

Head. Eyes bare but with the usual minute and scattered hairs, separated at level of anterior ocellus by 0.12– 0.13 of head width; frons divergent towards lunule; ocellar triangle with a pair of setae and a few setulae; 13–14 pairs of frontal setae; postpedicel 2.0–2.4 times the length of pedicel; pedicel with 1 seta and a few short setulae; arista plumose, with about 16 cilia, bare apicad, and with some secondary plumes as far as level of 3rd to 5th cilia; vibrissa shorter than arista; 1 supravibrissal seta, less than half the length of vibrissa, and a few setulae that extend to level of apical fourth of postpedicel; about 5 subvibrissal setae followed by about 11 genal setae. Palpus expanded at apex.

Acrostichals 0+1; dorsocentrals 0+3; intra-alars 1+2; presutural 1; prealars 2, shorter than half the length of first supra-alar; supra-alars 2; postpronotals 3; notopleuron with 2 long, subequal setae and covered with ground-setulae; postalars 2; no intrapostalar; scutellum with 1 basal, 1 latero-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 3–4 long setae; prosternum broad and setulose; anepisternum with a posterior row of about 9 setae, without upcurved setae on upper-anterior corner, and covered with short setulae; katepisternals 1+2; anepimeron extensively setulose on posterior half; katepimeron bare; anatergite bare; katatergite setulose. Legs: fore femur with complete posterodorsal and posteroventral rows of setae, and a posterior row of setae longer on apical half; fore tibia with a dorsal row of short and strong setae, 1 anterodorsal and 1 posteroventral preapical setae, and anterior surface with a brush-like ctenidium of golden setulae; fore tarsus with some long setulae on basal segment; mid femur without a tubercle and with about 3 posterodorsal to posterior setae, and no ventral setae; mid tibia with a dorsal row of very short and strong setulae, 1 posterodorsal seta on middle third and 3 strong posterior setae, 1 on basal third, 1 on middle third and 1 on apical third, and 2 anteroventral, 1 posteroventral and 1 ventral apical setae; hind femur with an anteroventral row of setae, strongest on apical third, an anterodorsal row of setae on basal two-thirds, and a few posteroventral setulae on apical fourth; hind tibia with 5 long and subequal anteroventral setae on apical two-thirds, 9 short posterodorsal setae on apical half, 3 posteroventral setae on apical third and 1 on middle third, 1 dorsal and 1 anterodorsal preapical setae, 1 anteroventral and 1 ventral apical setae, and a posterior brush-like ctenidium; hind tarsus with a golden brush ventrally. Wing with a uniform covering of microtrichia; dm-cu almost straight; stem-vein bare before, and with 4 short setulae after, humeral cross-vein on dorsal surface, and ventrally with about 2 short setulae before, and bare after, humeral cross-vein; R2+3 bare on dorsal and ventral surfaces; R4+5 setulose from base to apex of wing; 3–4 strong setae on basicosta.

Abdomen. With a lateral tuft of setulae on syntergite 1+2, tergites 3–5 with normal setulae; sternite 1 setulose; posterior margin of sternite 5 concave and with many setae on membrane.
