Nagashima,  15 August 2001( DOAT).   Diagnosis.Being closely related to  S. sauteri(Poppius),  S. schuhi, new speciescan be distinguished by smaller size; narrower vertex; wider yellowish subbasal annulation on antennal antennomere II; antennomere III longer than IV; roundly inflated sensory lobe of left paramere; T-shaped apex of right paramere; anchor-shaped apex and roundly inflated sensory lobe of left paramere; narrowed sclerotised rings; and mesally separated interramal lobes, in addition to being associated with a herb from the Urticaceae,  Urtica dioica.   Description.Body ovoid, stout, rather box-like, small-sized; in female body larger and paler in colour ( Fig. 7G–I); basic colouration shiny dark reddish brown; dorsum polished, finely and sparsely punctate, with uniformly distributed, pale, simple, reclining or semi-erect setae on mesoscutum, scutellum and hemelytra. Head shiny pale brown, partly tinged with red, almost glabrous; eyes small; basal transverse carina on vertex with several upright setae, about as thick as pronotal collar ( Fig. 34K). Antenna dark brown; antennomere I with darkened apex, base and middle; antennomere II with pale ring at basal ⅓, as long as or slightly shorter than basal width of pronotum; base of antennomere III whitish, longer than IV. Labium pale brown, reaching but not exceeding apex of metacoxa; segment IV reddish brown. Pronotum shiny pale or reddish brown, shallowly punctate or rugose, almost glabrous ( Fig. 29K); calli sometimes with a pair of dark spots, flat; pleura pale brown; metathoracic scent efferent system greyish brown, with rather flat peritreme ( Fig. 35A); scutellum shiny fuscous, with creamy V-shaped margin. Hemelytron shining, pale brown or reddish brown, widely darkened posteriorly, declivous at cuneal fracture; cuneus yellowish brown apically, with dark apex; membrane pale smoky brown. Coxae and legs pale brown, partly tinged with red; meso- and metacoxa, and base of each femur more or less darkened; tibiae with dark spots or annulations at bases of pale brown spines; tarsomere III darkened; meta-tarsomere II as long as III; pretarsal structures as in Fig. 30C. Abdomen fuscous; female sterna VII–IX pale brown. Male genitalia ( Figs. 18A–D, 35D−F): Left paramere with roundly inflated sensory lobe ( Figs. 30D); right paramere with elongate hypophysis and T-shaped, flat apex ( Figs. 18C, 35E). Vesica widely membranous, with two lobal-sclerites, one of which is deeply notched; secondary gonopore thick-rimmed ( Figs. 18D, 35F). Female genitalia ( Figs. 18E–G, 35G−I): Genital chamber with small, narrow sclerotised rings that are separated to each other ( Fig. 35G); posterior wall lacking dorsal structure or lateral lobe; interramal lobe comparatively narrow, densely covered with spinules ( Fig. 35I), each lobe separated mesally ( Fig. 35H).  Fig. 31.

Schuh (Curator Emeritus, AMNH), one of the world’s most prominent heteropterists and my long-time mentor; an adjective.   Distribution. Nepal(Kathmandu Valley, Kasuki), Thailand( Chiang Mai).   Biology.In Kathmandu Valley, several adults of this new species were found to inhabit  Urtica dioicaL. ( Urticaceae) and to coexist on the herb with  Himalisundacoris duwalaeunder deciduous/evergreen mixed broadleaf forest ( Fig. 7J). On the other hand, the Taiwanese congener,  S. sauteri(Poppius), has been collected from the inflorescences and flower-buds of broadleaf trees, such as  Styrax formosanusMatsum.( Styracaceae) ( Fig. 7L). Chérot et al. (2017)reported that a PapuaNew Guinean congener,  S. zhengi Chérot, Gorczyca, Schwartz & Demol, 2017, was collected by canopy-fogging. 2006-08-02 NMTU, AMNH Nepal Mt.
