Coniceromyia leia sp. nov.

( Figs. 4B , 8T , 14H , 20 A–B, 24U, 26D)

Diagnosis (male). Ventral face of foretibia mostly bare and shiny but with sparse differentiated thin setulae ( Fig. 26D ).

Material examined. Holotype ♂, COLOMBIA: Amazonas : PNN Amacayacu: Mocagua, 3.82ºS, 70.26ºW, 19–31.vii.2000, Malaise trap, 150m, A. Parente col. ( IAVH) [LACM ENT 073436].

Description. Male. Body length 2.3 mm. Head. Frons brown, sparsely setulose, with well-defined median furrow. Flagellomere 1 light brown, conical-elongate. Arista apical, about 1.5 flagellomere 1 length. Palpus yellowish-brown with thin, elongate ventral setae. Gena with two setae. Thorax. Scutum, scutellum, and pleural regions brown; anepisternum dorsally setulose. Legs yellowish-brown; hind femur brown at apex. Forefemur broadened ventrally with shallow excavation. Foretibia with two dorsal setae, short anterodorsal row of orange setulae, isolated anteroapical seta, and anterodorsal to dorsal excavation bearing small microtrichia. Ventral face of foretibia mostly bare and shiny but with sparse differentiated thin setulae, anterior row of setulae, and apical patch of fine, dense, orange setulae. Foremetatarsus with anterior excavation, setulose anteroapical process, patch of orange setae and long black seta at base of excavation, row of setulae on dorsal margin of excavation, and seta at base of anteroapical process ( Fig. 8T ). Foremetatarsus ratio 0.29. Posterior face of hind femur with basoventral group of tiny blunt setulae, tapering toward ventral margin, dorsal setulae thicker ( Figs. 20 A–B). Hind femur height/length ratio 0.38. Hind tibia with one dorsal seta in basal half. Wing ( Fig. 14H ). Costa swollen, 0.41 of the wing length; R 2+3 absent; M 1 concave, curved posteriorly at apex; M 2 sinuous, CuA 1 -M 2 /M 2 -M 1 ratio 1.33; CuA 1 slightly sinuous. Halter white.

Abdomen. Tergites dark brown, with shining pubescence. Hypopygium light brown ( Fig. 24U ). Left epandrial process with dorsal margin invaginated near base and with a digitiform projection. Other characteristics could not be seen as we decided to not dissect the only known specimen of this species.

Distribution. Known from a single low-elevation site in Colombia.

Etymology. Name derived from the Greek word leios (smoth, bald), referring to the mostly bare ventral face of foretibia.
