Coniceromyia bisetosa sp. nov.

( Figs. 1E , 8E , 13E , 17 I–J, 24E, 27C)

Diagnosis (male). Foremetatarsus with two large setae at excavation base, dense curved setae at ventral margin of excavation, and row of short strong curved setulae at dorsal margin of excavation ( Fig. 8E ).

Description. Male. Body length, 2.5 mm. Head. Frons brown to dark brown, sparsely setulose, with well-defined median furrow. Flagellomere 1 brown, conical very elongate. Arista apical, about one quarter flagellomere 1 length. Palpus yellowish-brown, setose with many additional setae, ventral setae thinner. Gena with two to four setae. Thorax. Scutum, scutellum, and pleural regions brown; anepisternum bare. Legs light brown, except anterior face of forefemur, foretibia and foretarsus yellowish-brown; foretarsomere 5 brown. Foretibia with three dorsal setae and anterodorsal row of strong setulae. Foremetatarsus widening toward apex, with anterior excavation, anteroapical setulose process, two large setae at excavation base, dense curved setae at ventral margin of excavation, row of short strong curved setulae at dorsal margin of excavation, and seta near base of anteroapical process ( Fig. 8E ). Foremetatarsus ratio 0.44. Hind femur with narrow basoventral band of tiny blunt setulae ( Figs. 17 I–J). Hind femur height/length ratio 0.31. Hind tibia with one dorsal seta in basal half. Wing ( Fig. 13E ). Costa swollen, 0.41 of the wing length; R 2+3 vestigial; M 1 concave, curved posteriorly at apex; M 2 slightly concave, CuA 1 -M 2 /M 2 -M 1 ratio 1.27; CuA 1 slightly sinuous. Halter white. Abdomen. Tergites dark brown, with shining pubescence. Hypopygium light brown, left epandrial process with only one discernible process: a subepandrial wall extending from the hypoproct to its apex. Right lateral lobe of hypandrium with large lateral projection. Hypoproct with two setae ( Fig. 24E ).

Distribution. Known from four mid-elevation sites in Colombian and Venezuelan Eastern Andean Cordillera ( Fig. 27C ).

Etymology. Name derived from the Latin roots bi (two, double) and seta (bristle), referring to the two large setae at the base of foremetatarsus.

Variations. Although additional setae are present on the palpus, some specimens lack the thinner ventral setae. Some specimens have two dorsal setae on the foretibia, also different than the holotype.
