( Figs. 7E, F , 13 , 26A–I , 27A–I )

Type material. Holotype: male, NEPAL: Kathmandu Valley : Lalitpur , Godawari, Mt. Pulchoki (1,500–1,800 m), 27°34′45″N, 85°22′44″E, on Urtica dioica, T. Yasunaga , 4 August 2006 ( NMTU) ( AMNH _ PBI 00378782 ) . Paratypes: 2 males, 2 females, same data as for holotype ( AMNH, TYCN, ZRC) ; 1 male, 2 females, same data as for holotype, except for date 2 August 2006 ( TYCN) .

Diagnosis. This new species is recognised by the following characters: Moderate size; yellowish brown, oily shiny, dorsum, with darkened clavus and posterior corium ( Fig. 7E, F ); and bright greenish or yellowish white scutellum, in addition to the characters provided in the above key.

Description. Body oval, slightly elongate; basic colouration pale brown with widely darkened hemelytra ( Fig. 7E, F ); dorsum polished, impunctate ( Fig. 26C ). Head pale whitish brown, smooth, with fuscous apical half (including jugum, lorum, buccula, and clypeus); vertex with faint, weak basal transverse carina ( Fig. 26B ); frons (in fresh specimens) tinged with red. Antenna dark brown; antennomere I partly and irregularly pale at middle; antennomere II shorter than basal width of pronotum; extreme base of antennomere III creamy yellow. Labium pale reddish brown, reaching anterior margin of metacoxa; apical half of segment IV darkened. Pronotum pale brown, more or less darkened posteriorly, almost glabrous; calli (in fresh specimens) with a pair of dark small spots, partly suffused with red; pleura uniformly pale reddish brown; metathoracic scent efferent system as in Fig. 26G ; mesoscutum and anterior half of scutellum with sparsely distributed, short setae ( Fig. 26D ); mesoscutum dark reddish brown; scutellum greenish or yellowish white, with fuscous extreme apex. Hemelytron dark brown, oily shiny, smooth, with uniformly distributed, pale, short, simple setae ( Fig. 26C ); basal ⅔ of clavus pale brown; subapical part of cuneus narrowly pale; membrane pale smoky brown, semi-transparent, with dark brown veins. All coxae and legs pale brown; each femur with two red, subapical rings; metafemur with broader reddish annulation at middle; apical part of each tarsomere III darkened; pretarsal structure as in Fig. 26I . Abdomen pale reddish brown; apical half of male genital segment (pygophore) fuscous. Male genitalia ( Figs. 13 A−G, 27A–E): Hypophysis of left paramere elongate ( Fig. 13A ), with barb-like apex ( Figs. 13B , 27B ); right paramere bulbous, ovoid, with short, pointed hypophysis ( Figs. 13D, E , 27C ); vesica with three notched lobal-sclerites ( Figs. 13F , 27D ). Female genitalia ( Figs. 13H, I , 27F–I ): Genital chamber circular, with elongate oval sclerotised rings ( Figs. 13I , 27F ); posterior wall with widened interramal lobes ( Figs. 13H , 27H ).

Measurements. See Table 1.

Etymology. Named to honour Dr. Ram Keshari Duwal, a Nepalese heteropterist (now working at CNC); a noun in the genitive case.

Distribution. Nepal (Lalitpur, Kathmandu Valley).

Biology. All available specimens of this new species were found from Urtica dioica L. ( Urticaceae ).
