Description. Male. Body length, 1.8 mm. Head. Frons brown, sparsely setulose, with weak median furrow. Flagellomere 1 light brown, globose. Arista subapical, about 2.5 times flagellomere 1 length. Palpus yellowishbrown. Gena with two setae. Thorax. Scutum, scutellum, and pleural regions brown; anepisternum bare. Legs yellowish-brown. Forefemur with two to three ventral rows of thin elongated setae. Foretibia with two to three dorsal setae and anterodorsal row of strong setulae. Foremetatarsus with anterior excavation, long anteroapical setulose process, group of setae at excavation base, and strong seta at base of anteroapical process ( Fig. 8B ). Foremetatarsus ratio 0.32. Hind femur with narrow basoventral band of tiny blunt setulae ( Fig. 17 C–D). Hind femur height/length ratio 0.33. Hind tibia with one dorsal seta in basal half; preapical seta shifted basally. Wing ( Fig. 13B ). Costa swollen, 0.44 of the wing length; R 2+3 absent; M 1 concave, not curved posteriorly at apex; M 2 sinuous, CuA 1 -M 2 /M 2 -M 1 ratio 1.7; CuA 1 sinuous. Halter brownish white. Abdomen. Tergites brown, with shining pubescence. Hypopygium light brown ( Figs. 24B ). Left epandrial process with a dorsal medially-directed setulose projection near hypoproct and a large irregular projection near apex. Margin of right lobe of hypandrium with a lateral projection. Hypoproct without setae.

Distribution. Known from mid and high-elevation sites in the Andes of Colombia, Ecuador and Venezuela.

Known from a single mid-elevation site in Colombia.

Etymology. Name derived from the Greek roots anisos (unequal) and krossos (fringe), referring to the ventral row of unequal setae on the forefemur.
