Description. Body oval, slightly elongate; basic colouration pale orange-brown ( Fig. 11G ); in female, clavus and apical part of corium darkened ( Fig. 11I ). Head pale orange-brown; vertex smooth, with faintly delimitated basal transverse carina ( Fig. 29B ); lorum, jugum, and buccula reddish brown; apical half of clypeus fuscous. Antenna dark brown; antennomere I pale brown, with darkened base and apex; antennomere II with pale subbasal annulation; base of antennomere III yellowish brown. Labium pale reddish brown, reaching middle part of metacoxa; apical part of segment IV dark reddish brown. Pronotum uniformly pale, almost glabrous ( Fig. 29A ); calli with a pair of reddish spots in female; pleura shiny pale reddish-brown; metathoracic scent efferent system pale brown, with small, semi-circular peritreme ( Fig. 29D ); scutellum pale creamy brown. Hemelytron pale orange-brown, with sparsely distributed, pale, simple, semi-erect setae; clavus and apical half of corium darkened in female; basal half and apex of cuneus sanguineous; membrane pale greyish brown, semi-transparent, with brown veins. All coxae and legs pale brown; metafemur with two or three reddish annulations apically; apex of each tibia dark reddish brown; apical half of each tarsomere III darkened; meta-tarsomere II as long as III ( Fig. 29E ); pretarsal structure as in Fig. 29F ; parempodia relatively short. Abdomen almost uniformly pale reddish brown. Male genitalia ( Figs. 13D–F , 29G–K ): Hypophysis of left paramere with sharp apex ( Fig. 29H ); right paramere ovoid, with short, pointed hypophysis ( Figs.13F , 29I ); vesica with distinctly notched lobal-sclerite ( Figs. 13D , 29J, K ); secondary gonopore comparatively large. Female genitalia ( Figs. 13H, I , 29L–O ): Sclerotised rings relatively large, subtriangular ( Fig. 29L ); dorsal margin of posterior wall with sparsely distributed, scaly micro-structures, lacking field of spinules ( Fig. 29N ); interramal lobes mesally separated to each other ( Fig. 29M ).
