Female macroptera . Colour: yellow with light brown markings as follows: anterior area of head, slender transverse pronotal blotch, mesonotal anterior margin; tergites II–VII with antecostal ridge dark and brown markings anterolaterally, VII–VIII with faint shading medially, IX–X yellow; fore wing grey, darkest sub-basally, apex pale; antennal segments I–II pale, III pale medially, also base of IV; hind tibiae yellow, femora lightly shaded. Structure: Occipital apodeme close to but not confluent with posterior margin of eyes, ocellar area striate ( Fig. 21 ); antennal segments III & IV with apex constricted into short neck; pronotum transversely striate including blotch with markings between the striae, transverse row of setae along anterior margin of blotch ( Fig. 21 ); mesonotum and metanotum striate; metasternal plate with shallow emargination; fore wing second vein with one or two setae distally; tergites VII–VIII with complete comb of microtrichia on posterior margin but comb short medially on VII, no comb on remaining tergites; tergite IX with 2 pairs of mid-dorsal setae. Material studied . Holotype female, BRAZIL , Minas Gerais , 22.vi.1933 ( CAS ). Comments . This species is known from a single female. Specimens in USNM bearing this name are now considered to be the new species described below, N. ikelus sp. n . The holotype is not in good condition, but the striate ocellar area is characteristic, and there are fine lines between the pronotal striae in contrast to N. ikelus . The fore wing is extensively but weakly shaded, with an indistinct paler area medially and the extreme apex pale, and antennal segment III is distinctly shaded at base and apex.
