Description. Male. Body length 2.5 mm. Head. Frons brown except yellow anterior margin, shining, with few setulae, setae thin, median furrow not clear. Flagellomere 1 yellowish-brown, globose. Arista apical, four times longer than flagellomere 1. Palpus yellowish-brown. Gena with two setae. Thorax. Scutum and pleural regions yellowish-brown except scutum posterior third with three brown triangular maculae, scutellum light brown; anepisternum bare. Legs yellowish-brown, except apex of hind femur brown, elongated, with setae reduced. Foretrochanter with ventral projection bearing apical group of curved setulae. Foretibia with one dorsal seta and anterodorsal row of slightly stronger setulae. Foremetatarsus with anterior excavation, anteroapical setulose process, group of setulae at base of excavation, and strong seta near base of anteroapical process ( Fig. 8D ). Foremetatarsus ratio 0.32. Posteroventral face of hind femur with band of tiny blunt setulae ( Figs. 17 G–H). Hind femur height/length ratio 0.25. Hind tibia with one dorsal seta in basal half. Wing ( Fig. 13D ). Brown macula from posterior margin of Rs to C, reaching the apex of Sc, and another at the apical third of the wing; Costa considerably swollen, 0.47 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 0.9; CuA 1 sinuous. Halter yellowish-brown. Abdomen. Tergites brown. Hypopygium light brown. Left epandrial process rectangular in lateral view, with a subepandrial wall extending from the hypoproct to its apex. Margin of right lobe of hypandrium without lateral projection. Hypoproct without setae ( Fig. 24D ).

Distribution. Known from mid-elevation sites Central to West of Brazil ( Fig. 27B ).

Etymology. Name derived from the Latin word bellatulus (beautiful).
