Coniceromyia pectinella sp. nov.

( Figs. 5F , 8 D’, 15F, 21H–I, 25G, 26H)

Diagnosis (male). Forefemur with an oval dorsoapical excavation bearing a comb of apically-directed curved setae ( Fig. 26H ), foretibia with row of six short strong setae extending from posterior region to ventroapical margin ( Fig. 5F ), foremetatarsus slightly inflated, with anterior excavation bearing fine, dense, orange small setulae and group of large curved setae at base of excavation ( Fig. 8 D’).

Material examined. Holotype ♂, ECUADOR: Pichincha: 17 km E Santo Domingo: above Tinalandia , 9– 13.v.1987, Malaise trap, 1150 m, B. Brown, L. Coote col. [LACM ENT 345887].

Description. Male. Body length, 2.7 mm. Head. Frons light brown, sparsely setulose, with weak median furrow. Flagellomere 1 light brown, conical elongate. Arista apical, subequal to flagellomere 1 in length. Palpus light brown. Gena with two setae. Thorax. Scutum, scutellum, and pleural regions light brown; anepisternum bare. Foreleg yellowish-brown, except forefemur light brown; mid and hind leg light brown. Forefemur with an oval dorsoapical excavation bearing a comb of apically-directed curved setae. Foretibia with three dorsal setae, anterodorsal row of strong setulae, and row of six short strong setae extending from posterior region to ventroapical margin. Foremetatarsus slightly inflated, with anterior excavation bearing fine, dense, orange small setulae, anteroapical setulose process, group of large curved setae at base of excavation, and strong seta at base of anteroapical process ( Fig. 8 D’). Foremetatarsus ratio 0.34. Posterior face of hind femur with broad basoventral group of tiny blunt setulae tapering toward ventral margin ( Fig. 21 H–I). Hind femur height/length ratio 0.37. Hind tibia with one dorsal seta in basal half. Wing ( Fig. 15F ). Wing margin slightly projected as a lobe between M 1 and M 2. Costa swollen, 0.39 of the wing length; R 2+3 vestigial as a tiny remnant attached to costa; M 1 concave, not curved posteriorly at apex; M 2 concave, CuA 1 -M 2 /M 2 -M 1 ratio 1.25; CuA 1 sinuous. Halter white. Abdomen. Tergites brown, with shining pubescence. Hypopygium yellowish-brown ( Fig. 25G ). Left epandrial process with a subepandrial wall extending from the hypoproct to its apex and a medially directed setulose projection near its base. Margin of right lobe of hypandrium without projection. Hypoproct with one seta.

Distribution. Known from a single mid-elevation site in Ecuador.

Etymology. Name derived from the Latin root pecten (comb), referring to the comb of apically-directed curved setae on the forefemur.
