Hammond det. 1978 (holotype and 4 paratypes in NHML ; 1 paratype in CRL ). Description: Proportions of holotype : length: 16.5 mm ; length of head: 2.6; total length of head: 3.0; breadth of head: 3.2; length of eye: 1.0; length of temple: 1.6; length of antenna: 3.3; length of pronotum: 3.1; breadth of pronotum: 2.9; length of elytron: 3.5; breadth of elytra: 3.7. Habitus: fig. 13. Integument entirely black except for apical margin of tergite VII and tergites VIII and IX reddish brown. Antennae and legs black. Head with some very sparse pale pubescence, the hairs long and very fine on frons and vertex, short, stouter and whitish on temples. Pronotum glabrous except for a few small scattered hairs and some larger, but still small short dark setae on lateral margins. Elytra glabrous near suture, in lateral halves with a longitudinal patch of rather sparse coloured hairs, brassy-coppery in inner part, whitish laterally. Abdominal tergites III-V with a patch of with a patch of long, recumbent black hairs in the middle near the anterior margin, the antero-lateral angles with sparse, short brassy yellowish hairs pointing in different directions; these patches larger and denser on tergite VII. Tibiae, especially protibiae, with conspicuous dense, long pale yellowish setae and a dense row of pale spines on inner faces. Sculpture of head relatively fine, composed as in many other species of isodiametrical umbilicate punctures in occipital and lateral areas, the interstices tending to coalesce into longitudinal rugae on vertex and frons; sculpture of pronotum equally fine or finer, the parallel rugae on anterior 1/4th very obliquely directed from mid-line towards lateral margins of scutellum; Mid-longitudinal band of pronotum only represented by a shiny irregular line near anterior and posterior margins; sculpture of abdominal tergites composed of very sparse fine punctures on a fairly shiny sericeous background of micropunctures and microsculpture; punctures of tergite VII coarser and less sparse. Male: sternite VII modified; sternite VIII with a very small emargination; aedoeagus: figs 13ad, 13al, the apex of the median lobe deeply excavate dorsally, the ventral side of spatulate apex with a pair of small teeth (both excavation and teeth visible in fig. 13al); basal sclerite and paramere unclear; ventral extension of the former apparently relatively short, sub-truncate; paramere apparently short, broad, the apical margin slightly concave, the anterior angles broadly rounded. This species is very similar to N. argentifer nov.sp. , below, differing in the sculpture of anterior part of pronotum, in the pale brassy pubescence on parts of elytra and tergites (entirely silvery in N. argentifer ), and most conspicuously by the sparse puncturation and alutaceous microsculpture of the abdominal tergites.
