 Redescription   
 Color. Body mostly yellowish brown to reddish brown. Eyes dark with irregular paler markings; third and fourth antennal segments, second antennal segment (except apex and base) brown; ventral surface of thorax, lateral sides of abdomen beneath brownish yellow; connexivum (except some small spots and posterior angles) generally brownish red to dark brown; spots on connexivum and abdominal venter, posterior angles of connexivum white to light yellow brown; membrane of hemelytron light brown, transparent; wax patches on disk cell of corium present or absent; venter of abdomen black with lighter spots and markings of different sizes (Figs. 2–4), sometimes nearly totally black (Fig. 5).   
 Structure. Body of large size. Body clothed with short bent pubescence and vertical long setae; first antennal segment with scattered oblique setae, second to fourth segments densely clothed with oblique pubescence; rostrum with scattered oblique short setae; ventral surface of abdomen with many short setae; legs with long setae, ventral surface of fore legs densely clothed with short pubescence. Head vertex bulging, anteocular portion shorter than postocular, anterior lobe of head with a “ Y ”­shaped depression; transverse constriction of head slightly posteriorly curved, arced; eyes of medium size; ocelli small and widely separated, interocellar space about 2 times as long as distance between ocellus and ipsilateral eye; antennae slender, first segment longer than head and subequal to pronotum in length; second and third segments nearly of same length; first rostral segment thickest and extending beyond middle of eyes, second segment longest and subequal to first and third segments combined, third segment shortest. Pronotum nearly as long as wide, lateral margin slightly concave, posterior pronotal lobe nearly 3 times as long as anterior lobe; collar protruding with a small tubercle; anterior pronotal lobe with deep, broad longitudinal depression at middle, lateral sides of middle depression with small processes; posterior pronotal lobe large, strongly dilated laterally, middle part of posterior margin tongue­shaped and extending backwards, not reaching or reaching disk cell of corium, and disk of posterior lobe distinctly bulging with irregular wrinkles, lateral part deeply sunken with three low round elevations (Figs. 1, 6); lateral pronotal angles obtuse. Legs nodular, fore femur slightly thicker than mid and hind femora; claws developed. Hemelytron extending beyond abdominal tip, veins of corium strong. Abdomen dilated laterally; connexivum large. Abdominal tip of female as shown in Figs. 7, 8. Pygophore oblong, median pygophore process round and wide; paramere small, clavate, bent in middle, round at apex, apical half with long setae (Figs. 10, 11); basal plate bridge of phallus thin, basal plate thicker than basal plate bridge; pedicel short and wide; phallosoma ovate in dorsal and ventral view (Figs. 14, 15); struts separated near base, extending beyond middle of phallosoma (Fig. 14); anterior margin of dorsal phallotheca sclerite nearly straight and slightly concave in middle, a short tongue­shaped, light­colored sclerite attached to apex of dorsal phallotheca sclerite (Figs. 14, 15).
