Redescription. Colour. Black, with blue reflections. Frontal vitta and fronto-orbital plate shining black on upper half, with white pruinosity on lower half and parafacial; face and inner portion of gena brown with white pruinosity, outer portion of gena without pruinosity; antenna brownish dorsally and yellowish ventrally; palpus yellow; legs brown; calypters brown, on outer half white and opaque; haltere white; mesonotum and abdomen with blue reflections, without pruinosity.

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

Head. Eyes bare, separated at level of anterior ocellus by 0.19–0.21 of head width; frons divergent towards lunule; ocellar triangle with a pair of setae and a few setulae; 11–13 pairs of frontal setae; postpedicel 1.8–2.1 times the length of pedicel; pedicel with 2 setae and a few setulae; arista plumose, with 17–19 cilia, bare apicad, and with some secondary plumes as far as level of 4th to 5th cilia; vibrissa longer than arista; 1 strong supravibrissal seta, less than half the length of vibrissa, and a few setulae that extend to level of middle of postpedicel; 5–6 subvibrissal setae followed by 9–10 genal setae. Palpus expanded at apex.

Thorax. Acrostichals 0+1; dorsocentrals 0+2; intra-alars 1+2; presutural 1; prealars 2, strong; supra-alars 2; postpronotals 3; notopleuron with 2 long, subequal setae and covered with ground-setulae; postalars 2; intrapostalar 1; scutellum with 1 basal, 1 latero-discal and 1 apical pairs of strong setae, and latero-ventrally with many setae, the basalmost ones downcurved; postalar wall and suprasquamal ridge with short pile; proepisternal depression bare; proepimeron with about 4 long setae; prosternum broad and bare; anepisternum with a posterior row of about 9 setae, without upcurved setae on upper-anterior corner, and covered with short scarce setulae; katepisternals 1+2; anepimeron setulose on anterior half and extensively setulose on posterior half; anatergite with short pile; katatergite setulose. Legs: fore femur with a posterodorsal row of short setae on apical two-thirds, and a posteroventral row of setae; fore tibia with an anterodorsal row of short and strong setae, 2–3 long posteroventral setulae, 1 dorsal, 1 anterodorsal and 1 posteroventral preapical setae, and anterior surface with a ctenidium of golden setulae; fore tarsus with some long setae on basal segment; mid femur without a tubercle, anterodorsal surface with a row of short setae and 3 agglutinated spines apically, 4 posterodorsal to posterior setae on apical half, and 6 ventral setae on basal third; mid tibia with an anterodorsal comb-like ctenidium of very short spinose setulae on basal half and fine setae on apical half, 1 posterior seta on middle third, a posteroventral row of 4 strong setae, 1 on basal third, 1 on mid third and 2 on apical third, and 1 anteroventral, 2 posteroventral and 2 ventral apical setae; hind femur with an anteroventral row of setae, strongest on apical third, an anterodorsal row of setae, and a few posteroventral setulae on apical fourth; hind tibia with 7 short and subequal anteroventral setae on apical two-thirds, 1 anterodorsal seta on middle third, a dorsal row of short but strong setulae, a posterodorsal row of short setae ending with 3 stronger on middle third, 1 dorsal and 1 anterodorsal preapical setae, 1 anteroventral and 2 posteroventral apical setae, and a posterior brush-like ctenidium; hind tarsus with a golden brush ventrally. Wing with a non-uniform covering of microtrichia; dm-cu sinuous; stem-vein with 1 short setula before, and bare after, humeral cross-vein on dorsal surface, and with 2 short setulae before, and bare after, humeral cross-vein on ventral surface; R2+3 bare on dorsal and ventral surfaces; R4+5 setulose from base to just before r-m on dorsal surface and beyond node on ventral surface; 1–3 strong setae on basicosta.

Abdomen. Tergites 3–5 with a few setae laterally; sternite 1 setulose; posterior margin of sternite 5 concave and with many setae on membrane.

Terminalia (figs 20–23 in Pamplona 1986b). Outer margin of cercal plate convex; cercal plate ventrally strongly curved; surstylus with setae basally and setae apically; aedeagus with many spicules on anterior membrane of distiphallus; gonopod with one long and strong seta on basal half and 2 setulae on apical half; paramere with some setae apically and setulae on middle third.

Female. Body length: 6.0 mm; wing length: 5.0–6.0 mm.

Similar to male, differing as follows: face and gena yellowish-brown; eyes separated at level of anterior ocellus by 0.41–0.42 of head width; fronto-orbital plate with 2 proclinate setulae and 2 reclinate setulae; mid femur without anterodorsal agglutinated spines apically; hind femur with 2 anteroventral setae on middle third and no ventral setae.
