(Figs. 1A, B, 2 F−H, 20G–O)
Type material. Holotype: female, INDONESIA: Bali, Tabanan, Bedugul Area, 8°16′S, 115°09′E, local collector, 8–12 August 1996 (ZRC) (AMNH _ PBI 00378778).
Diagnosis. This new species is currently known only by a single female specimen and recognised readily by the following characters: Pale ivory brown general colouration; relatively large size; weak basal transverse carina on vertex; darkened apex of clypeus, annulated antennomere I; dark, short, interrupted stripes along veins on hemelytra; and semi-circular dorsal structure and narrow, less-spinulate, subtriangular interramal lobe on posterior wall.
Description. Holotype female: Body generally pale ivory brown (Fig. 1A, B); dorsal surface shining, impunctate, with sparsely distributed, pale, short, reclining setae. Head shiny creamy brown; basal carina on vertex reduced, flat; apex of clypeus and ventral half of buccula infuscate. Antenna dark brown, relatively short; antennomere I pale brown, with obscure basal half and darkened extreme apex; antennomere II pale basal half (except for dark base), shorter than basal width of pronotum; base of antennomere III pale. Labium pale reddish brown, reaching apex of metacoxa; apical ¼ of segment IV darkened. Pronotum polished, with a pair of small, circular spots on calli; collar about as thick as base of antennomere II; thoracic pleura milky brown; metathoracic scent efferent system as in Fig. 20I; scutellum shining, tinged with red at apex. Hemelytra with rather uniformly distributed, short, reclining setae; clavus and corium with dark, short, fragmentary stripes; paracuneus with a dark, small spot; apex of cuneus fuscous; membrane pale greyish brown, semi-transparent, with brown veins. All coxae and legs pale brown; metafemur with two brown, apical rings that are obliterated posteriad; tibia with small dark spots at bases of spines; apical part of each tarsomere III dark brown; pretarsal structure as in Fig. 20K. Abdomen pale brown, speckled with reddish brown ventrally. Female genitalia (2F−H, 20L–O): Sclerotised rings ovoid, rather small, separated to each other mesally (Figs. 2F, 20L); Posterior wall with a row of spines on anterior part of interramal sclerite interrupted mesally (Figs. 2G, 20M); dorsal structure wide, semi-circular, with densely distributed spinules (Fig. 20N, O); interramal lobe small, subtriangular (Figs. 2G, 20M).
