Description. Male. Body length, 2.2 mm. Head. Frons brown, sparsely setulose, with well-defined median furrow. Flagellomere 1 light brown, conical-elongate. Arista apical, about as long as flagellomere 1. Palpus yellowish-brown. Gena with two setae. Thorax. Scutum, scutellum, and pleural regions brown; anepisternum bare. Legs yellowish-brown. Foretibia with two dorsal setae and anterodorsal row of strong setulae. Foremetatarsus with anterior excavation, anteroapical setulose process, excavation ventral margin strongly projected anteriorly, forming a triangle, group of setae at base of excavation, and strong seta at base of anteroapical process ( Fig. 8M ). Foremetatarsus ratio 0.35. Posterior face of hind femur with narrow basoventral band of tiny blunt setulae ( Fig. 19 A–B). Hind femur height/length ratio, 0.38. Hind tibia with one dorsal seta in basal half. Wing ( Fig. 14A ). Costa swollen, 0.38 of the wing length; R 2+3 absent or vestigial as a tiny remnant attached to costa; M 1 slightly concave, curved posteriorly at apex; M 2 basal half approximately straight, slightly sinuous near apex, CuA 1 -M 2 /M 2 -M 1 ratio 1.8; CuA 1 slightly sinuous. Halter white. Abdomen. Tergites dark brown, with shining pubescence. Hypopygium light brown ( Fig. 24N ). Left epandrial process with a subepandrial wall extending from the hypoproct to its apex and a medially directed setulose projection near its base. Hypoproct with two setae.

Distribution. Low-elevation sites in Central America to Caribbean Coast of Colombia, Venezuela, and Trinidad ( Fig. 27G ).

Etymology. Name derived from the Greek letter delta (triangle) and podos (foot), referring to the triangular projection of the foremetatarsus.
