Coniceromyia ochyrosticha sp. nov.

( Figs. 5D , 8 B’, 15D, 21E, 25E)

Diagnosis (male). Forefemur with posteroventral row of seven strong setae near apex; foretibia with three to five dorsal setae ( Fig. 5D ).

Material examined. Holotype ♂, VENEZUELA: Mérida: Mérida: La Montaña , 31.iii–1.iv.1988, Malaise trap, 2436m, A.T. Finnamore, C. Baxfield col. [LACM ENT 049264] . Paratypes: 1♂, same as holotype but 3.iv.1988, pan trap; 1♂, same but 8.40°N, 71.13°W, 8.iv.1988; 1♂, same but 10–14.iv.1988.

Description. Male. Body length, 3.1 mm. Head. Frons brown to dark brown, sparsely setulose, with well-defined median furrow, and elongate frontal setae. Flagellomere 1 brown, conical elongate. Arista apical, about half flagellomere 1 length. Palpus light brown. Gena with two setae. Thorax. Scutum, scutellum, and pleural regions brown; anepisternum bare. Fore and mid leg yellowish-brown, except base of femora brown; hind leg light brown. Forefemur with posteroventral row of seven strong setae near apex. Foretibia with three to five dorsal setae, anterodorsal row of strong setulae, and short setulae on ventral face. Foremetatarsus with anterior bare excavation, anteroapical setulose process, excavation ventral margin slightly projected anteriorly near base, group of short setae at excavation base, row of short strong setulae on excavation anterior margin, and strong seta at anteroapical process base ( Fig. 8 B’). Foremetatarsus ratio 0.34. Posterior face of hind femur with narrow basoventral band of tiny blunt setulae ( Fig. 21E ). Hind femur height/length ratio 0.32. Hind tibia with one dorsal seta in basal half. Wing ( Fig. 15D ). Costa swollen, 0.43 of the wing length; R 2+3 vestigial as a tiny remnant attached to costa or absent; M 1 concave, curved posteriorly at apex; M 2 nearly straight to slightly sinuous, CuA 1 -M 2 /M 2 -M 1 ratio 1.6; CuA 1 sinuous. Halter base brown, apex yellowish-brown. Abdomen. Tergites dark brown, with shining pubescence. Hypopygium light brown ( Fig. 25E ). Left epandrial process with only one discernible process: a subepandrial wall extending from the hypoproct to its apex. Margin of right lobe of hypandrium with a subtle lateral projection. Hypoproct without setae.

Distribution. Known from a single high-elevation site in Venezuela.

Etymology. Name derived from the Greek roots ochyros (strong) and stichos (line, row) referring to the row of seven strong setae near the apex of the forefemur.
