Mid to small sized dark flies, 13 17mm. Femora entirely black. The dorsal epandrial lobe projection is excised and sharp at its apex, and forms a shallow, oval cavity with the lower, ventral projection (Figs. 10, 53, 54). The distal, ventral gonostylus apex is distinctly rounded (usually seen externally, without dissection) (Fig. 23).
Head: Face yellow and gray pollinose. Gibbous area in lateral aspect unevenly contoured, projecting sharply above; ventral margin tapering into oral margin and gena. Gena gray tomentose with black hair. Mystax dense, dorsal portion black, medially white, ventral short white hair. Palpus hair yellow basally, black apically. Lower occipital fringe with light yellow hair; medial portion with longer black proclinate hair; upper, dorsal area with black, strongly proclinate hair. In lateral aspect, dorsal proclinate hair extends over eye margin. Distance between dorsal margin of facial gibbosity and antennal base equal or less the length of antennal segment 1 (scape).

Basal areas of hind femur, in anterior and anterodorsal aspect, yellow and black tomentose; 4 anterior bristles and 3 short apical bristles; anterodorsal surface with 2 long apical bristles, a semi circlet of weak short apical bristles; a ventral fringe of long white and black hair. Fore tibia reddishyellow; basal apex with a short band of black, wider ventrally, distal apex black; black tomentose; 1 anterior apical bristle; 1 basal anterodorsal bristle, 2 apical bristles; posterolateral surface with 3 long yellow apical bristles and a fringe of long yellow and black hair; a ventral fringe of thick yellow tomentum extends half way apically. Mid tibia with 3 anterodorsal bristles, an apical circlet of bristles; posterolateral surface with 2 bristles; ventral surface with long yellow hair. Hind tibia with 3 long anterior bristles, a circlet of apical bristles, anterodorsal surface with 3 weak bristles, a fringe of thick yellow tomentum extends half way apically to first elongated tarsal segment; ventral surface with 2 apical bristles, a short fringe of thick yellow tomentum on apical surface. Tarsomeres with apical bristles, black dorsally, yellow ventrally. Wings: Tinged brown at apex and margins. Abdomen: Dull black. Tergites 6–8 shiny blue black. Tergites 1 5 short black tomentose; tergite 1 with short yellow medial hair, long yellow lateral hair and bristles on tergites 3–5; lateral hair absent on subsequent tergites; tergites 5–7 with short black tomentum. Sternites 1–5 with long yellow hair, shorter apically. Dorsal epandrial lobe projection excised, sharp at apex forming shallow oval cavity with lower ventral projection (Figs. 10, 53, 54). Gonostylus apex rounded (Fig. 23). Ovipositor elongated, compressed, similar to N. angusticornis (Fig. 65).
