Membranes brown with concolour venation and distinctly visible, irregularly arranged spots. Dark markings on membranes visible in the base and lateral part of apical external cell as well as in the lateral and apical part of membrane ( Figs 1, 15 ). Pale setae on costal vein. Connexivum bicolorous whitish and brown with thin, short, black line on margin of brown part; on pale part of connexivum, small brown spot connected with external margin. Abdomen beneath yellowish with irregular brown markings and four distinct spots (two external, brown placed laterally, near posterior margin of sterna and two internal dark brown placed near anterior margin of sterna) on each sternum. In middle part of each abdominal sterna V-shaped markings with line in center ( Fig. 17 ). Pygophore yellowish with lateral, brown, irregular markings ( Fig. 2 ).

Structure: Medium-sized, robust body with distinct sculpturation on head, pronotum, and scutellum as well as on the margins of connexivum. Head with distinct granulations. Clypeal processes as well as processes on antennifers granulated. Clypeal processes are 2 times longer than antennifer processes. Long, thin setae on head are placed on granules. Granules in posterior area of postocellar part of head are distinctly larger. Basal part of the first labial segment with V-shaped indentation and distinctly visible labrum. Ocelli with mediumsized tubules with distinct suture between them. Eyes globular in dorsal view and slightly elongated in lateral view. Postocular part of head visible, wider than anteocular part. First antennal segment surpassing apex of head by half of its length and slightly curved; in middle part with few long setae and several medium-sized, erected setae. Second antennal segment with dense, regularly arranged, long and medium-sized setae. Long setae visible from 1/3 of length of segment. Third antennal segment with long and medium-sized setae. Labial segments with medium-sized, erected setae. Second labial segment surpassing posterior margin of eyes (almost reaching posterior margin of head). Anteocular part of head 1.7 times as long as postocular part. Pronotum with long setae placed on granulations. Anterior pronotal lobe with distinct granulations and longitudinal, dull areas without granulations ( Fig. 1). Apical part of anterior pronotal lobe with granulated lateral calli. Collar indentation rounded. Longitudinal depression with small and very rare granulations, distinctly hollowed in 1/3 of posterior part. Two large, connected granules visible in middle of 1/3 posterior part of mentioned depression. Posterior pronotal lobe distinctly granulated with central, longitudinal, wide depression. Posterior margin of posterior pronotal lobe not granulated. Scutellum granulated with long setae and rounded apex. Propleura with very distinct collar surrounding coxae. Meso- and metathoracic sterna with distinct sculpture and granulations. Sternal part of thorax without granulations. Inner and dorsal side of fore coxae and trochanters granulated with short setae. Fore coxae with three long spines, two longest near the basal and apical part. Middle and hind coxae and trochanters without granulations, with short setae. Fore femora fusiform with one line of large spines (irregular near apex) on ventral side as well as with line of medium-sized setae beneath. Dorsal part of fore femora with regularly arranged granulations with long setae placed on them. Fore tibiae with rather dense medium-sized setae on dorsal surface and small number of scarce setae on ventral surface. Middle and hind femora and tibia with medium-sized, regular setae. Hind femora wider in apical part. Hemelytra dull with setae placed on veins. Basal part of costal vein with small granules and very short, erected setae. Abdomen beneath dull with very short and very thin setae. Abdomen, in ventral view, with longitudinal, fine, and wide depression visible on each sterna (except II visible sternum). Posterior margin of each sterna (except II visible sternum) in the line of depression distinctly rounded. Dark spots slightly hollowed. Longitudinal sculpturation of connexiva distinctly visible in dorsal view. In ventral view sculpturation visible on posterior part of each connexivum and on tip of abdomen. Posterior part of each connexivum enlarged. External margin of connexivum with small granules and medium-sized setae.

Genitalia: Male - Pygophore with distinct transversal hollow in apical part with distinct ridge near apical margin ( Figs 2, 3 ). Ridge of pygophore distinctly convolute ( Fig. 3 ). Middle process of pygophore slightly bent on its right side with rounded apex ( Fig. 2 ). Both parameres ( Figs 4–9 ) slender, long, and distinctly curved (almost on 90º) in middle part. Ventral and dorsal part of each paramere with medium-sized setae, these slightly longer and more visible on dorsal side. Apical part of right paramere rounded in dorsal view. Apical part of left paramere flattened. Both parameres distinctly hollowed in middle of apical part in ventral view. Left paramere with very small process on inner side, this process with rounded apex. Phallosoma elongated ( Figs. 10–11 ) with wide, rounded membrane on lateral parts ( Figs. 12–14 ).
