Coniceromyia valdesi   new species

Recognition. C. valdesi   is most easily differentiated from other patterned-wing Coniceromyia   by the break or weakening in wing vein M 2. The oval arrangement of ventral setae and lack of darkened pigment on the wing further distinguish this species from others.

C. valdesi   keys near couplet 12 in the Kung & Brown key (2000 a). The wing patterning of C. valdesi   is not due to darkening of the membrane, but rather to short, dense setae arranged in an oval, and the break or weakening in vein M 2. C. valdesi   lacks three striae on the wing, differentiating it from C. striativena Borgmeier. The   lack of darkening on the wing membrane between the anterior margin and M 1 prevent the second lead in the couplet from being followed.

Description. Body length 1.88–2.16 mm, mean 2.05 mm. Frons dark brown. Frontal height 1.05–1.13 frontal width, mean frontal ratio 1.08. Flagellomere 1 brown, pyriform. Palpus light brown. Scutum, scutellum, and pleuron dark brown to brown. Anepisternal setae absent. Legs mostly brown, femora darker than tibiae and tarsi. Foretibia with 2 dorsal to anterodorsal setae. Foretarsomere 1 broadened apically, with anterior excavation, covered in short, dense, orange setae; with long, anterobasal seta, seta approximately three-quarters length of foretarsomere 1; with narrow anteroapical process ( Fig. 4 View FIGURES 1 – 4 ). Foretarsus tapered apically. Tarsomeres 2–4 of foreleg about as long as wide. In one specimen, tarsal ratio of foretarsus 2.17:1.00:1.00:1.00:1.00. Basal one-third of posterior face of hind femur with triangular, ventral group of FIGURES 17–22. Scanning electron micrographs, wings, low magnification and high magnification. 17–18.

small, blunt peglike setae; arrangement of peglike setae tapered towards ventral margin ( Figs. 11–12 View FIGURES 9 – 12 ). Hind tibia with one dorsal seta in basal half. Costa slightly thickened (Fig. 16). Wing vein R 2 + 3 entirely absent. Wing membrane with fold visible across vein M 2; posterior to M 2 basally, anterior to M 2 apically (Figs. 19–20). Venter of wing membrane with elongate oval arrangement of short, dense setae posterior to M 2 (Figs. 16, 21– 22). Wing veins M 1 and M 2 parallel basally, diverging apically, with M 1 anteriorly directed at apex; M 2 relatively straight. Apical two-fifths of vein M 2 narrowed; M 2 with small break or weakening at narrowing (Figs. 16, 21– 22). CuA 1 relatively straight, curved anteriorly at apex. Costa length 0.42–0.46 wing length, mean 0.44. Halter white. Abdominal tergites brown to dark brown. Venter of abdomen brown or gray. Left surstylus of genitalia broad, truncate ( Fig. 26 View FIGURES 23 – 26 ). Left hypandrial lobe dorsoapically directed, with large dorsal expansion.

Distribution. Colombia.
