Coniceromyia sakaii new species

( Figs. 3 , 9–10 , 15, 17–18, 25; Morphbank images 477865, 477866, 477867)

Recognition. This species is easily distinguished by the long, ventral setae on the wing, in addition to thickened costa and sinuous CuA1 wing vein. Foretarsomere 1 of C. sakaii lacks a basal seta and has a broad anteroapical process.

C. sakaii keys to couplet 6 in the Kung & Brown key (2000a). This species differs from C. hoggi , C. blomae and C. apicalis by the lack of darkening of the wing membrane, and by the presence of long, ventral setae on the wing.

Description. Body length 2.20–2.68 mm, mean 2.35 mm. Frons dark brown, subshiny. Frontal height 0.91–1.05 frontal width, mean frontal ratio 0.99. Flagellomere 1 orange, elongate pyriform. Palpus yellow. Scutum and scutellum yellow. Pleuron yellow. Anepisternal setae present. Legs yellow. Differentiated anterior to anterodorsal setae on foretibia present or absent. If present, 3–10 setae present, arranged in a straight or uneven row. Foretarsomere 1 with anterior excavation ( Fig. 3 ). Excavation without basal seta, with broad, laterally flattened anteroapical process. Foretarsus tapering apically; in one specimen, tarsal ratio 3.00:1.80:1.60:1.50:2.00. Posterior face of hind femur with small, blunt peglike setae on basal two-fifths, arranged in a broad oval basally, and tapering apically along ventral margin ( Figs. 9–10 ). Hind tibia with 2 dorsal to near-dorsal setae in basal half. Wing short, broad, with costa thickening apically, apex greater than twice thickness of basal half (Figs. 15, 17). Venter of wing membrane between veins M1 and A1+CuA2 covered in long, thin setae (Figs. 15, 17–18). Wing vein R2+3 entirely absent. Wing veins M1 and M2 relatively parallel. CuA1 sinuous, bent anteriorly near median. A1+CuA2 faintly present. Costal length 0.59–0.62 wing length, mean 0.61. Halter white. Abdominal tergite 1 yellow. Tergites 2–6 mostly yellow to light brown, laterally brown to dark brown. Venter of abdomen white. Left surstylus of genitalia broad ( Fig. 25 ). Left hypandrial lobe greatly expanded apically, triangular.

Distribution. Colombia.
