Redescription. Color. Body dull yellowish brown; head, anterior pronotal lobe, propleural episternum, meso- and metapleura of thorax, thoracic sterna, scutellum (except apical spine), most of all coxae, posterior half of connexival segment (including spine) blackish brown to black; posterior pronotal lobe, propleural epimeron dull yellowish brown to dull reddish brown; second antennal segment (except subapical annulation), third and fourth antennal segments, rostrum dull brown to blackish brown; subapical annulation on second antennal segment orange to yellowish brown; first antennal segment, apical spine of scutellum, lateral pronotal spines, ventral surface of abdomen, legs (except some annular markings) yellowish brown; apical portion of fore tibia brown; obscure subapical annulation on femora, two median indistinct broad annulations on tibiae; apical portion of fore tibia dark brown; abdominal tip suffused with black; hemelytra dull brown, with pale yellowish brown markings.

Structure. Most of body surface clothed with pale pubescence; antennae with short setae, two apical segments with few long setae; legs with short setae and sparse oblique long setae. Head cylindrical, without process or with indistinct round elevation behind antenniferous tubercles; anterior and posterior lobes of head subequal in length, anterior lobe with Y-shaped sulcus; first rostral segment subequal to second and extending beyond middle of eyes, apical segment shortest; first antennal segment subequal to pronotum in length, and nearly as long as half of second segment; eyes large and laterally protruded. Collar undeveloped, lateral processes cone-shaped produced; pronotum wider than long, median longitudinal sulcus not reaching posterior margin ( Fig. 53 ); anterior pronotal lobe subequal in length to half of posterior; lateral pronotal angles with long, suberect spines produced laterally; posterior lobe slightly rugose; apical spine of scutellum erect, long, acute and feebly pointed backwards; anterior angle of prosternum anteriorly with a short obtuse spine; femora of even thickness; basal half of fore tibia slightly thin, apical half distinctly broadened; femora beneath subapically with a short spine; fore femur subequal in length to fore tibia; forewing not reaching or just extending beyond abdominal tip. Pygophore oval, posterior margin broad and round ( Figs. 58–59 ), median process shown in Figs. 58, 59 ; paramere clubbed, most basal portion compressed, apex curved and with a small process ( Figs. 60–62 ). Basal plate bridge thin and subequal to basal plate in length, basal plate thick ( Figs. 64 ); pedicel broad and relatively short; struts mostly fused, straight, long and nearly extending to tip of phallosoma, apart at base, apex relatively widely separated ( Figs. 64 ); dorsal phallothecal sclerite relatively somewhat narrow apically ( Figs. 64 ); endosoma with two spoon-shaped sclerites ventral-laterally ( Figs. 64 ).
