Color. Brown, slightly shiny. Antenna, most of corium, apical half of clavus dark yellow; eyes, and markings around ocelli black; spot under ventral margin of eye blackish brown; spot on corium next to clavus, anterior margin of distal half of corium, and most of membrane dark brown; head above, most of rostrum, legs, most of margins of membrane of hemelytron, and abdomen (except second sternite) grayish brown. Structure. Head, pronotum ( Figs. 2, 3 ), posterior 4/5 of scutellum, abdominal sterna, parameres with thick, scattered setae of varying lengths; antenna, except first segment, densely covered with short semierect setae, first antennal segment with scattered long, oblique, thick setae ( Figs. 4–5 ), second segment with a few trichobothria ( Figs. 7, 8 ), third ( Fig. 9 ) and fourth ( Fig. 10 ) segments with scattered, oblique, somewhat longer setae; basal 1/5 of scutellum, meso- and metathoracic pleura and sterna densely covered with short bent setae; femora and mid tibia with long, suberect or erect, thick setae ventrally. Head relatively short and thick, 1.3 times as long as wide, 0.6 times as high as long; anteocular portion about 3 times as long as postocular portion; first antennal segment thickest; first rostral segment thickest, second segment slightly shorter than combined length of the remaining segments and extending beyond posterior margin of eye; ocelli relatively large, distance between ocelli subequal to distance between eye and ipsilateral ocellus ( Fig. 2 ). Collar process distinctly tuberculate and with a thick seta distally ( Fig. 2 ). Anterior pronotal lobe convex but with longitudinal median depression, lateral pronotal angle round, posterior margin of pronotum distinctly convex posteriorly; stridulitrum consisting of about 190 transverse ridges; fore coxae long and thick, fore femora thickest ( Fig. 11 ), mid femora ( Fig. 12 ) slightly thicker than hind femora ( Fig. 13 ), mid and hind tibiae compressed; hemelytron extending slightly beyond abdominal tip. Abdomen slightly dilated laterally ( Fig. 1 ). Eighth abdominal sternite as shown in Fig. 14 . Parameres subtriangular, left paramere slightly longer than right, apical portion of left paramere more slender than that of right, medial surface of apex of paramere with a process ( Figs. 18–21 ); median pygophore process strongly curved, apex sharp ( Figs. 15–17 ). Phallus in resting position ( Figs. 22, 23 ) with basal plate short, basal plate bridge longer than basal plate; pedicel slightly longer than basal plate bridge in length ( Figs. 22, 23 ). Dorsal phallothecal sclerite moderately sclerotized, middle portion longitudinally depressed ( Figs. 23, 24 ); struts slightly longer than half length of phallosoma in resting position ( Fig. 24 ). Conjunctiva with two ventral lobes, basal one semicircular, apical one nearly rectangular ( Fig. 25 ). Basal portion of vesica densely covered with small processes and with a sacshaped process dorsally; apical portion with a long tubular process with many rows of smaller processes ( Fig. 25 ).
