Neomuscina atincta Snyder 1949: 5 (key), 27 (description); Snyder 1954: 425 (key); Pont 1972: 50 (catalogue); d’Almeida 1992: 381 –386 (listed); d’Almeida 1993: 7 –16 (synanthropy); de Carvalho et al. 1993: 57 (catalogue); Couri & de Carvalho 2002: 153 (key); Couri & de Carvalho 2005: 9 (listed); de Carvalho et al. 2005: 93 (catalogue).

Diagnosis: acrostichal 0:1; dorsocentral 2:4; mid femur with two preapical setae; hind tibia with two dorsal median anterolateral setae; wing hyaline; male with intra-alar 1; proepimeron with three outstanding setae.

Color: general body coloration brown; scutum with four dark stripes of grey pruinosity; frons yellowbrownish, apex darkened; parafrontalia yellow; facialia and parafacialia light yellow, antenna and palpus yellow, humeral callus and apex of scutellum yellow; legs dark brown; calypters and halter yellow; wing hyaline.

Male. Length. Body: 6.1 mm; wing: 6.4 mm.

Head: eyes separated from each other by 0.8 mm, at level of ocellar tubercle; 13–14 pairs of frontal setae; ocellar seta small and convergent; postocellar seta small and divergent; inner vertical and outer vertical setae small and divergent.

Thorax: acrostichal 0:1; dorsocentral 2:4; intra-alars 2; proepimeron with three setae; fore tibia with a distinct submedian anterodorsal seta; apex of fore tibia with setae on anterodorsal, dorsal, posterodorsal and ventral surfaces; mid femur with a row of setae on posteroventral surface from base to middle; mid femur with two preapical setae, on posterodorsal and posterior surfaces; apex of mid tibia with setae on the anterior, dorsal, posterodorsal, posteroventral, ventral and anteroventral surfaces; hind femur with a complete row of anterodorsal, posteroventral and anteroventral setae; hind tibia with two median anterodorsal setae and five to six median anteroventral setae; wing with one dorsal and one or two ventral setae at apex of stem vein.

Comments: N. atincta was recorded for Brazil by d’Almeida (1992, 1993). Although the MNRJ’s collection has material from Rio de Janeiro State, including the localities studied by d’Almeida, it does not have representatives of this species. Similarly, the DZUP and MZUSP’s collections also do not have any specimen of N. atincta , which could indicate an identification error. Neomuscina atincta can be distinguished mainly by the two median anterodorsal setae on the hind tibia. Here we present only the redescription of the holotype, and do not provide drawings. The material collected by d’Almeida was not seen.
