Description. Male. Body length, 2.2 mm. Head. Frons brown, sparsely setulose, with well-defined median furrow. Flagellomere 1 brown, conical. Arista apical, about same length as flagellomere 1. Palpus light brown. Gena with two setae. Thorax. Scutum, scutellum, and pleural regions brown; anepisternum with thin, sparse setulae. Legs light brown, except foretibia and tarsi yellowish-brown. Foretibia with two dorsal setae and anterodorsal row of strong setulae. Foremetatarsus with anterior bare excavation, anterior preapical setulose process, group of setae at base of excavation, and strong seta at base of anterior preapical process ( Fig. 8 A’). Foremetatarsus ratio 0.3. Posterior face of hind femur with narrow basoventral band of tiny blunt setulae ( Fig. 21 C–D). Hind femur height/ length ratio, 0.3. Hind tibia with one dorsal seta in basal half. Wing ( Fig. 15C ). Costa swollen, 0.41 of the wing length; R 2+3 absent or vestigial; M 1 concave, curved posteriorly at apex; M 2 slightly sinuous, CuA 1 -M 2 /M 2 -M 1 ratio 1.8; CuA 1 sinuous. Halter base brown, apex light brown. Abdomen. Tergites dark brown, with shining pubescence. Hypopygium light brown ( Fig. 25D ). 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 projections. Hypoproct with two setae.

Distribution. Mid-elevation sites in Costa Rica ( Fig. 28C ).

Etymology. Name derived from the Latin word numerosus (many), referring to the high number of specimens collected of this species.

Variations. Specimens with one dorsal seta on foretibia; base of foremetatarsus slightly projected anteriorly.
