( Figs 17View FIGURES 15 – 23, 46View FIGURES 41 – 49, 54View FIGURES 50 – 66, 87View FIGURES 80 – 91)

Female macroptera. Colour: body bicoloured ( Fig. 87View FIGURES 80 – 91), head brown with postoccipital area paler, pronotal blotch dark brown with anterior area pale with dark reticulate lines; mesonotum and metanotum dark brown, tergites II– VII with antecostal ridge dark brown, II–IV brown laterally, V–VI mainly yellow but shaded brown medially, VII– IX dark brown, X light brown; fore wing brown with sub-basal pale band, an indistinct pale median area and apex sometimes a little paler, clavus dark at base with dark setae; antennal segments I–II weakly shaded, III–IV pale with apex light brown; hind tibiae yellow, femora brown.

Structure: Occipital apodeme confluent with posterior margin of eyes, ocellar area with widely spaced striae, setal pair III on margins of ocellar triangle ( Fig. 17View FIGURES 15 – 23); antennal segments III & IV with short constricted apical neck; pronotum boldly reticulate on anterior and posteromedian areas, blotch striate with transverse row of setae on anterior margin ( Fig. 17View FIGURES 15 – 23); mesonotum striate, median setal pair anterior to the lateral ( Fig. 46View FIGURES 41 – 49); metanotum anterior half transversely striate, posterior half longitudinally striate, two pairs of setae on anterior margin; metasternal plate with distinctive anterior emargination ( Fig. 54View FIGURES 50 – 66); fore wing second vein with 2 setae distally; tergites II–VI with comb of microtrichia incomplete medially, VII with minute teeth medially, VIII with complete comb; tergite IX with 2 pairs of mid-dorsal setae; sternites without microtrichia medially.

Measurements (holotype female in microns): Body length 1185, Head, length 63, width 1680; ocellar setae III length 24. Pronotum length 113, width 185. Fore wing length 685. Antennal segments I–VIII length 23, 34, 54, 51, 43, 48, 10, 13.

Male macroptera. Male similar to female, but tergites V and VII light brown; sternites without pore plates.

Measurements (paratype male in microns): Body length 940, Head length 63, width 140; ocellar setae III length 15. Pronotum length 100, width 165. Fore wing length 565. Antennal segments I–VIII length 23, 35, 49, 46, 36, 38, 8, 10.

Material studied. Holotype female, BRAZIL, Santa Catarina State, Nova Teutônia [Seara], on Myrtaceae  , 5.xii.1949 (JDH 2077) (F. Plaumann) ( USNMAbout USNM). 

Paratypes: 31 females and 4 males collected with holotype (JDH 2077) ( USNMAbout USNM); Rio Grande do Sul State  , Cambará do Sul, Parque Nacional Aparados da Serra, 1 female on Myrcia retorta  , 27.i.2013 (A. Cavalleri) ( UFRGSAbout UFRGS)  .

Comments. Along with N. basilaris  , N. fimbriatus  and N. daedalus  , this is one of four species with the anterior area of the pronotum boldly reticulate. Unlike the others, the pronotal blotch is dark brown in contrast to the pale anterior third of the pronotum. As indicated above, the colour of the fore wings is variable with the distal paler areas indefinite.
