Description. Male. Length = 5.1–5.3 mm (n = 8).

Head. Fronto-orbital, parafacial plates and postocular strip with yellowish-gray microtomentum. Frontal vitta black. Six frontal setae. Gena and postgena with golden microtomentum. Palpus yellow or light brown.

Thorax. Chaetotaxy: dorsocentrals 2+4 (first two weak); intra-alars 3+2; supra-alars 1+3, notopleurals 1 subprimary; anepisternals 5; merals 5. Ctenidium consisting of three spines. Mid femur with three median setae and with a differentiated posteroventral seta. Wing hyaline; with dark spot beginning in the terminal portion of vein R 1, filling the distal third of cell r 1 and the upper half of the distal half of cell r 2+3; vein R 4+5 setulose dorsally to crossvein r-m.

Abdomen. Tergites brown with a band of grayish microtomentum on anterior 4/5 of dorsal and lateral surfaces. Sternites 2 and 3 yellow with a median brown strip on posterior margin and sternite 4 brown, with yellowish setulae and with marginal setae.

Terminalia. Sternite 5 brown; cleft deep, nearly reaching middle of sternite; lobe rounded, with a tuft of short setulae and with two prominent thick setae basally; arm very narrow and small, with rounded apex ( Fig. 30E View FIGURE 30 ). Cercus shorter than epandrium, almost straight, with a small apical protuberance on dorsal margin in lateral view ( Fig. 30A View FIGURE 30 ). Cercal prongs parallel with a preapical tuft of long setulae on inner lateral margins in dorsal view ( Fig. 30B View FIGURE 30 ). Surstylus almost triangular, covered with setulae, except on anterior margin and with long and fine setae apically ( Fig. 30A View FIGURE 30 ). Pregonite wide and short (shorter than postgonite), with rounded apex and distal half perpendicular to base; posterior margin with short and pointed setae ( Fig. 30C View FIGURE 30 ). Postgonite almost straight, with narrow and pointed apex curved anteriorly; posterior margin with a long seta (longer than postgonite) and small pointed setae ( Fig. 30D View FIGURE 30 ). Basiphallus short, about half as long as distiphallus, with proximal region narrowed and curved dorsally. Distiphallus elongate, with dorsal margin sinuous and apical margin rounded with a small concavity close to ventral margin ( Fig. 30F View FIGURE 30 ). Ventral margin of distiphallus with region just above basal portion of vesica twisted, bearing a pointed projection with serrated apex ( Fig. 30F View FIGURE 30 ). Vesica dome-shaped ( Fig. 30F View FIGURE 30 ). Lateral and median styli small, about one-third width of the widest portion of lateral wall of distiphallus, and both inserted close to apical surface of distiphallus ( Fig. 30F View FIGURE 30 ).

Etymology. This species is named in honor of our friend and young dipterist Sofia Lins Leal Xavier de Camargo.

Distribution. NEOTROPICAL—Brasil (Acre, Amazonas, Pará).

Remarks. This species is similar to N. travassosi and N. distincta in having vein R 2+3 with setulae ventrally and a dome-shaped vesica. The lack of a small apical point on the surstylus and the presence a small concavity near the ventral margin of the distiphallus differentiate this species from N. travassosi and N. distincta , in which the apical surface of the distiphallus is entirely convex. In addition, the shapes of the ventral margin of the distiphallus of these three species are remarkably distinct. In N. distincta the ventral margin shows a glossiform plate-like projection strongly curved towards basal portion of the distiphallus, whereas in N. travassosi the glossiform plate-like projection is directed anteriorly. In N. sofiae sp. nov. the projection is twisted and not glossiform.
