Neomuscina mediana Snyder 1949: 5 View in CoL (key); 19 (description); Snyder 1954: 424 (key); Pont 1972: 50 (catalogue); d’Almeida 1993: 7 –16 (synanthropy); de Carvalho et al. 1993: 58 (catalogue); Lopes & Khouri 1996: 959 (cited as near N. paramediana View in CoL ); Couri & de Carvalho 2002: 152 (key); Couri & de Carvalho 2005: 9 (listed); de Carvalho et al. 2005: 94 (catalogue); Schühli et al. 2011: 134 (listed).
Diagnosis: acrostichal 0:1; dorsocentral 2:4; mid femur with two preapical setae; hind tibia with one median anterodorsal setae; general body color dark brown; male: fifth sternite with strong basal projection; cercus blunt apically.
Color: general body coloration dark brown, near black; frons yellow, apex darkened; facialia, parafacialia, gena, antenna and palpus yellow; scutum with four dark stripes of grey pruinosity; humeral callus and apex of scutellum yellow; fore femur with the basal third dark brown; median and hind femora with the basal two thirds dark brown; calypters brownish yellow; halter dark yellow; wing hyaline, with dark cloud running from Sc apex to R1 apex and joining with dark cloud on r-m; R2+3 with dark cloud on the apex; dm-cu with a light dark cloud.
Male. Length. Body: 4.2–6.0 mm; wing: 4.5–5.2 mm.
Head: eyes separated from each other by 0.08–0.16 mm, at level of ocellar tubercle (in some males the frons is clearly visible); 10–11 pairs of convergent frontal setae (if the frons is visible, then the setae are strong); ocellar seta large and parallel; postocellar seta large and divergent; inner vertical seta small and convergent; outer vertical seta small and divergent.
Thorax: acrostichal 0:1; dorsocentral 2:4; intra-alar 1 (some males do not have intra-alar setae); apex of fore tibia with setae on anterodorsal, dorsal, posterodorsal and posteroventral surfaces; mid femur with a row of setae on posteroventral surface from base to middle, reappearing near apex; mid femur with two preapical setae, on posterodorsal and posterior surfaces; apex of mid tibia with setae on anterior, dorsal, posterodorsal, posterior, posteroventral, ventral and anteroventral surfaces; hind femur with a complete row of dorsal, posteroventral and anteroventral setae; hind tibia with one median anterodorsal seta and two or three median anteroventral setae; hind tibia with anterior, anterodorsal, dorsal, ventral and anteroventral setae at the apex; wing with one dorsal and one or two ventral setae at apex of stem vein.
Abdomen: fifth sternite with sharp basal projection; epandrium with moderate basal projection; cercus blunt apically.
Female (differing as follows): Length. Body: 5.4–6.5 mm; wing: 4.4–5.8 mm; eyes separated from each other by 0.29–0.33 mm, at level of ocellar tubercle; 9–10 pairs of frontal convergent setae, except for top two pairs, which are parallel; ocellar seta large and postocellar seta small, both divergent; inner vertical seta large and convergent, and outer vertical seta large and divergent; intra-alars 2; ventral microtrichia on segment VIII; sternite VIII with strong spike-like setae; epiproct with four setae, the setae in a square-shaped arrangement (2:2).
Comments: N. mediana can be distinguished mainly by its dark brown color, very close to black; some males have considerable variation in the distance between the eyes, and the frons is visible in many individuals. There are no differences in the terminalia of the specimens examined, which supports the hypothesis that the variation in the eyes is intraspecific. Some males lack intra-alar setae.
