( MZUSP) [MZ053403] . Paratypes: BRAZIL: 2♂, Rondônia: Guajará-Mirim: Rio Ouro Preto , 10°58’23”S 65°05’39”W, 20–27.x.1995, Malaise trap, J.A. Rafael & A.L. Henriques col. ( MZUSP) ; 2♂, Minas Gerais: Monte Azul: Serra de Montevidéu Formosa , 15°12’19.1”S 42°48’02.5”W, 30.xi–6.xii.2015, Malaise trap, 1141m, L.N. Perillo col. ( MZUSP & UFMG) .

Description. Male. Body length 1.6 mm. Head. Frons dark brown, sparsely setulose, with well-defined median furrow. Flagellomere 1 light brown, globose. Arista apical, four times longer than flagellomere 1. Palpus yellowish-brown. Gena with two setae. Thorax. Scutum, scutellum, and pleural regions brown; anepisternum bare. Legs yellowish-brown. Forefemur anteroventral margin slightly expanded ventrally, with slightly elongated setae in basal half. Foretibia with two dorsal setae and anterodorsal row of strong setulae. Foremetatarsus with anterior excavation, anteroapical setulose process, very strong curved seta at base of excavation, and strong seta near base of anteroapical process ( Fig. 9J ). Foremetatarsus ratio 0.37. Posterior face of hind femur with broad basoventral group of tiny blunt setulae, dorsal setulae thicker ( Fig. 23A ). Hind femur height/length ratio 0.29. Hind tibia with one dorsal seta in basal half. Wing ( Fig. 16D ). Costa considerably swollen, 0.39 of the wing length; R 2+3 absent; M 1 concave; M 2 basal two thirds approximately straight, apical third sinuous, diverging from M 1, CuA 1 -M 2 /M 2 -M 1 ratio 1.47; CuA 1 sinuous. Halter white. Abdomen. Tergites dark brown. Hypopygium yellowish-brown ( Fig. 25Q ). Left epandrial process rectangular in lateral view, with three apical lobes and a setulose subtle subepandrial elevation. Margin of right lobe of hypandrium without lateral projection. Two setae on hypoproct.

Distribution. Low and mid-elevation sites from Central to West of Brazil ( Fig. 28G ).

Etymology. Name derived from the Latin roots tri and lobus, referring to the three apical lobes of the left epandrial process.
