This species differs from all known congeners by the following characters: head nearly completely black (sometimes with yellow patch beneath scapes and eyes). Pronotum lateral lobe either black with small brown spot on postero-ventral corner, or black in dorsal half and yellow in ventral half. Male FW with basal area brown with tint of black, otherwise mostly hyaline; veins mostly yellow. Female FW with dorsal field mostly infumated black, with veins dark brown and lighten towards lateral field and apical areas. Legs red brown; FIII black dorso-basally without bands or stripes on external surface; with a distinct black ring before hind knee; hind knee black.Abdomen with tergites black, sternites mostly black. This species is similar to N. crucius   sp. nov. and N. rindu   sp. nov. but differs by the combination of these characters: frons nearly completely black (without black cross marking as in N. crucius   sp. nov.), dorsum of head completely black (vs with yellow margins in N. crucius   sp. nov. or pale with dark patterns in N. rindu   sp. nov.) and lateral lobe either with ventral half yellow or with an oval yellow spot at the anterior end (vs with a characteristic dorsal yellow band that extends ventrally in N. rindu   sp. nov.).

Scapes black, posterior end red brown. Antennae red brown with some segments black and with wide whitish rings. Eyes dark green when alive and red brown when dried. Frons generally black, sometimes with yellow to cream-coloured bands above and beneath antennal cavity and along ventral margins of eyes ( Fig. 10A View Fig ). Mouthparts dark red brown to black. Maxillary palpi creamcoloured; apical segment black apically ( Fig. 10A View Fig ). Head lateral side black ( Fig. 12A View Fig ). Pronotum generally black, covered with white setae; dorsal disk trapezoidal, posterior margin bisinuated ( Fig. 11A View Fig ).

Cell d2 narrower than d1. Apical field short and rounded, with 2 wide cell alignments posterior to mirror and a narrow apical alignment; veins yellow. Lateral field with 5–6 projections of Sc. Epiproct black. Subgenital plate pale cream, its median area and anterior and posterior margins black.

Pseudepiphallus sclerotized, relatively large and broad compared to congeners, anterior margin somewhat broad and straight, posterior margin also straight, lateral margins faintly converging posteriorly. Posterior apex with paired lophi longer than wide (at base), subacute at apex, sclerotized laterally only and covered with strong short setae; spaced apart from one another. Rami swollen preapically, anterior apex somewhat truncated. Pseudepiphallic parameres narrow, divergent posteriorly, their basis membranous, with a sclerotized lobe on anterior apex. Ectophallic arc transverse, complete, with anterior and posterior margins straight. Ectophallic fold strong rounded lateral sclerites appearing bean-shaped. Ectophallic apodemes long and thin, straight and slightly divergent basally.

FOREWINGS. FW colouration ( Fig. 14A View Fig ): cells on dorsal field mostly infumated black, gradually becoming yellow near CuA, M and R veins; veins generally black or dark brown, also gradually becoming yellow towards CuA, M and R veins; veins near apical area also yellow. Sc projections cream-coloured basally, black apically. Lateral field dark. FW venation: 6–7 strong longitudinal veins on dorsal field, sometimes not smooth; lateral field with 6 projections of Sc.

GENITALIA. Ovipositor: on average longer than FIII; apex thin with both dorsal and ventral edges smooth.
