Diagnosis. Specimens of N. inca are distinguished from similar congeners of the araucaria group by the following characters: appearance generally dark, particularly the legs; face moderately setose; gena high; and structures of male terminalia with distinctive conformation. Medium-sized to moderately large shore flies, body length 3.30– 4.60 mm; generally dull, grayish brown to gray with some subshiny areas dorsally.

Head: Head ratio 0.72–0.74; frontal ratio 0.49–0.53; mesofrons with dark bluish green to greenish metallic luster, generally pilose laterally; ocellar triangle and parafrons nearly concolorous, microtomentose, brownish gray to charcoal gray; parafrons becoming more charcoal colored anteriorly; fronto-orbits with narrow strip through insertions of fronto-orbital setae subshiny, with some faint metallic luster, number of fronto-orbital setae usually 2. Antenna mostly concolorous, blackish brown. Facial ratio 0.97–1.03; mostly moderately setulose particularly along oral margin and toward posteroventral portions of face; dorsum of interfoveal hump with subshiny area more or less concolorous with mesofrons, otherwise face densely microtomentose, grayish brown to gray, paler along oral margin. Eye ratio 0.97–0.98; gena-to-eye ratio 0.51–0.53; gena high, coloration gray to whitish gray but with faint tinges of olivaceous green to brown posteriorly.

Thorax: Mostly microtomentose; scutum mostly brown, darker and subshinier posteriorly; anterior margin microtomentose, especially postpronotum, gray to brownish gray; pleural areas paler, more gray colored especially ventrally; anepisternum with central area, dorsal and sometimes posterior margins brownish, otherwise mostly gray; other pleural areas including coxae whitish gray, although lighter, whitish ventrally. Wing length averaging 3.83–3.96 mm; mostly palely infuscate, faintly brown; costal vein ratio 0.26–0.29; M vein ratio 0.76–0.80. Legs dark generally; femora gray, microtomentose, only slightly darker than ventral pleural areas; tibiae and tarsi mostly concolorous, reddish yellow.

Abdomen: Generally microtomentose and unicolorous, grayish olivaceous green to gray, becoming paler toward lateral margins, some specimens with faint bluish tinges of metallic luster; ventral surface of tergites frequently whitish gray. Tergite 5 of male somewhat trapezoidal, truncate apically. Male terminalia ( Figs. 79–81 View FIGURES 79 – 81 ): margins of epandrium in posterior view parallel, rounded dorsally; surstyli in posterior view roughly forming isosceles triangle with an apical process; surstylus in lateral view basically rectangular with an apical, digitiform, short process and a longer lateral prong, length of lateral prong about equal to width of surstylus at base, lateral prong with sub-basal tuft of setulae, anterior margin between apical process and lateral prong shallowly produced, shallowly triangular.
