Coniceromyia stichochaeta sp. nov.

( Figs. 7A , 9G , 16A , 22 H–I, 25N, 28F)

Diagnosis (male). Anepisternum dorsally setulose, hind femur with narrow posteroventral band of tiny blunt setulae, left epandrial process with only one discernible process: a subepandrial wall extending from the hypoproct to its apex. This species is similar to C. amazonensis , C. brachypoda , C. dasypoda , and C. hadrochaeta from which it can be differentiated by its hind femur group of setulae of similar thickness and left epandrial process without any dorsal lobes.

Description. Male. Body length 2 mm. Head. Frons brown, sparsely setulose, with well-defined median furrow. Flagellomere 1 light brown, conical-elongate. Arista apical, slightly longer than flagellomere 1. Palpus light brown. Gena with two setae. Thorax. Scutum, scutellum, and pleural regions brown; anepisternum dorsally setulose. Legs yellowish-brown. Foretibia with two dorsal setae and anterodorsal row of strong setulae. Foremetatarsus with anterior excavation bearing a row of strong short setulae, anteroapical setulose process, strong curved seta at base of excavation, and strong seta near base of anteroapical process ( Fig. 9G ). Foremetatarsus ratio 0.42. Posterior face of hind femur with narrow basoventral band of tiny blunt setulae ( Fig. 22 H–I). Hind femur height/length ratio 0.37. Hind tibia with one dorsal seta in basal half. Wing ( Fig. 16A ). Costa swollen, 0.4 of the wing length; R 2+3 absent; M 1 concave, curved posteriorly at apex; M 2 approximately straight, CuA 1 -M 2 /M 2 -M 1 ratio 1.7; CuA 1 slightly sinuous. Halter white. Abdomen. Tergites brown. Hypopygium yellowish-brown ( Fig. 25N ). Left epandrial process with only one discernible process: a subepandrial wall extending from the hypoproct to its apex. Margin of right lobe of hypandrium without lateral projection. Two setae on hypoproct.

Distribution. Low and mid-elevation sites from Costa Rica to Western Colombia and Ecuador ( Fig. 28F ).

Etymology. Name derived from the Greek roots stichos (line, row) and chaite (long hair, seta), and refers to the row of strong setulae on the foremetatarsus excavation.
