Coniceromyia balbiae   sp. nov.

( Figs. 1C View FIGURE 1 , 8C View FIGURE 8 , 13C View FIGURE 13 , 17 View FIGURE 17 E–F, 24C)

Diagnosis (male). Left epandrial process bifurcated into a dorsal and a ventral lobe ( Fig. 24C View FIGURE 24 ); spacing between wing veins M 2 and CuA 1 not widened (CuA 1 -M 2 /M 2 -M 1 ratio 1.66). These characteristics are shared with C. dolichopoda   and C. megalosoma   , from which C. balbiae   can be differentiated by its considerably smaller body length, legs not elongated, and foretibia without posterodorsal row of strong setae.

Material examined. Holotype ♂, BOLIVIA: La Paz: 40km N Caranavi: Cumbre Alto Beni, 15.83ºS, 67.56ºW, 7–14.iv.2004, Malaise trap, 1600 m, B. Brown, E. Zumbado col. [LACM ENT 194073] GoogleMaps   . Paratypes: 1♂, same as holotype; 3♂, same but 12–15.iv.2003, Brown, Marcotte, Zumbado col.; 1♂, same but 14–21.iv.2004, B. Brown, E.

Description. Male. Body length, 2.4 mm. Head. Frons dark brown, shining, sparsely setulose, with welldefined median furrow. Flagellomere 1 light brown, conical very elongate. Arista apical, about one-third flagellomere 1 length. Palpus light brown. Gena with two setae. Thorax. Scutum, scutellum, and pleural regions brown; anepisternum bare. Legs yellowish-brown. Foretibia with two dorsal setae and anterodorsal row of strong setulae. Foremetatarsus with anterior excavation mostly bare except for two to three tiny setulae which may be difficult to see, anteroapical setulose process, group of setae at excavation base including one long curved seta, row of setulae at dorsal margin of excavation and strong curved seta at base of anteroapical process ( Fig. 8C View FIGURE 8 ). Foremetatarsus ratio 0.36. Posterior face of hind femur with semicircular basoventral group of tiny blunt setulae tapering toward ventral margin ( Fig. 17 View FIGURE 17 E–F). Hind femur height/length ratio 0.41. Hind tibia with one dorsal seta in basal half. Wing ( Fig. 13C View FIGURE 13 ). Costa swollen, 0.39 of the wing length; R 2+3 vestigial; M 1 concave, curved posteriorly at apex; M 2 concave, CuA 1 -M 2 /M 2 -M 1 ratio 1.66; CuA 1 slightly sinuous. Halter white. Abdomen. Tergites brown to dark brown, with shining pubescence. Hypopygium light brown ( Fig. 24C View FIGURE 24 ). Left epandrial process bifurcated into a dorsal and a ventral lobe. Ventral lobe with many strong setulae at medial face. Right subepandrial plate expanded posteriorly.

Distribution. Known from two mid-elevation sites in Western Bolivia.

Etymology. Named in honor of Maria Isabel P. Balbi, technician of our lab in Brazil and dear friend who has greatly inspired and supported this work.

Variations. Specimens with brown basodorsal macula on forefemur; base of midfemur brown, and brown hind femur; R 2+3 may be completely absent; M 2 variable, concave to sinuous.
