( Figs 63–66 ) Female macroptera . Strongly bicoloured; head brown with postoccipital region and anterior half of pronotum yellow; pronotal blotch and pteronota, also meso and metasternum, dark brown; abdominal segment I yellow with antecostal ridge interrupted medially, II–VI yellow scarcely shaded anterolaterally, antecostal ridge slightly darker, VII–X dark brown; legs mainly brown, hind tibiae variably yellow to brown, all tarsi yellow; forewings with pale sub-basal area before light brown band but uniformly pale in distal half. Head with occipital carina close to eyes; ocellar triangle transversely striate with markings in between the striae; ocellar setae III within anterior margins of triangle; three pairs of postocular setae, median pair long; postoccipital region transversely striate; mouth cone unusually long, extending to mesosternum. Pronotum anterior third transversely reticulate with few internal markings; blotch transversely striate with many markings between the major lines; posterior margin of blotch deeply concave, posteromedian discal setae arise behind the dark area. Mesonotum and metanotum with many small linear markings between the major sculpture lines, metanotal reticulation irregular but mainly linear. Metasternal anterior margin with shallow emargination. Forewing with no setae on second vein; wing apex with long sub-apical lobe. Tergites I–VI medially without marginal microtrichia; IV–V with few discal microtrichia medially. Sternites II–VII medially without marginal microtrichia, discal microtrichia not extending to setae S2. Measurements . Holotype female in microns: Body length 1020. Head, length 290; width across eyes 150. Pronotum, length 85; width 175. Forewing length 660. Antennal segments III–VIII length 55, 48, 48, 45, 8, 15. Male . Similar to female, abdominal segment VII yellow; sternites V–VII with broadly transverse glandular area. Material studied . Holotype female, Northern Territory , Katherine, from Fabaceae shrub, 19.vii.1993 (LAM 2485), in ANIC . Paratypes : 6 females , 5 males collected with holotype ; Northern Territory , Top Springs, 50km east, 1 female from grasses, 24.vii.1993 . Western Australia , Kununurra, 2 female , 1 male from Tephrosia coriacea fls, 25.ii.2005 ; Mt Keith, 1 female swept, v.1995 . Comments . As indicated in the key above, this species is closely related to N. haydni but has the mouth cone unusually elongate. It apparently replaces that eastern Australian species in the north of this continent.
