Diagnosis. Distinguished from the other congener, N. nagamasai sp. nov., by its medially darkened, wider vertex; dark striae on frons; brown ring near base of antennomere I; basally annulated antennomere II; longer labium reaching apex of metacoxa; widely concaved median part of metathoracic scent efferent system; and darker pronotum and hemelytra, in addition to allopatric distribution pattern of each species.

Description. As in generic description. Basic coloration pale brown; dorsum relatively shining, with dark maculae ( Figs 3C–D View Fig ), almost glabrous ( Figs 3C View Fig , 15L View Fig ). Head pale grayish brown; vertex irregularly darkened mesially, wide, 0.28–0.30 (J) / 0.32–0.34 (♀) times as wide as head across eyes; frons with several dark brown striae. Antenna pale brown; segment I with brown ring near base; segment II with dark apical 1/3 and two annulations in middle and at base, about as long as metafemur; apical half of segment III and apical 3/4 of IV brown. Labium shiny pale brown, slightly exceeding apex of metacoxa; segment I and apical 1/3 of segment IV dark reddish brown. Pronotum brown, irregularly and widely speckled with fuscous maculae (as in Figs 3C–D View Fig ), with creamy yellow collar and posterior margin; pleura castaneous, somewhat matte; metathoracic scent efferent system with creamy yellow, widely and semi-circularly concaved medially ( Fig. 15M View Fig ); scutellum yellowish white, with triangular fuscous macula at base and dark apex. Hemelytron shiny pale brown, with dark brown, rather squared macula on median corium; apical part and inner half of clavus darkened; base of corium darkened; cuneus fuscous brown, margined by scarlet fascia, with creamy yellow apex; membrane pale smoky brown, semitransparent. Coxae and legs pale brown; procoxa partly reddish brown; legs pale brown; metafemur sometimes with brown rings apically; apical part of metatibia partly darkened; metatarsomere II shorter than III ( Fig. 15I View Fig ); pretarsal structures as in Fig. 15J View Fig . Abdomen castaneous brown. Male genitalia ( Figs 5E–G View Fig , 6F–G View Fig , 16L–P View Fig ): left paramere with stout sensory lobe and sharp hypophysis ( Figs 5E View Fig , 16N View Fig ); vesical spicules and lobal sclerites elongate ( Figs 5G View Fig , 6G View Fig , 16O–P View Fig ). Female genitalia ( Figs 5H View Fig , 16H–J View Fig ): sclerotized rings semi-circular, relatively small, separated from each other mesally ( Fig. 5H View Fig ).

Measurements. See Table 1.

Etymology. Named for Nepal; latinized as an adjective.

Biology. The adults were collected by sweep-netting the inflorescences of Mallotus sp. ( Euphorbiaceae ). However, its accurate breeding host is yet to be confirmed with immature forms.

Distribution. Nepal (Makawanpur District, or subtropical savanna-zone of southern Himalayas).
