Description. ( Fig. 1 A View Fig ) Tylus convex, transversely rough, except apical lobe, jugum and anterior half of pronotum with sparse punctures; anterior margin of pronotum concave, delimited by a series of setigerous punctures. Ventral margin of prosternal carina prosternal rounded ( Fig. 2 A View Fig ). Head, III, IV, and V antennal segments, pronotum, scutellum, and abdomen dark brown. Hemelytra, legs, and rostrum pale yellow.

Head. Anterior half without punctures, tylus tranversally rough except apical lobe which has four fine and long spines; rostrum short reaching base of mesosternum.

Thorax. Pronotum with anterior margin concave, delimited by a series of setigerous punctures, anterior half elevated with sparse punctures, anterolateral margins slightly carinated, and posterior half densely punctuated. Propleura dull and smooth; prosternal carina low and with ventral margin lobulated ( Fig. 2 A View Fig ). Mesopleura with evaporatorium expanded towards posterior and lateral margins. Metapleura flat with evaporatorium reaching middle part of pleura; peritreme elongated with dark brown border; posterior margin of evaporatorium with setigerous punctures well defined ( Fig. 3 A View Fig ). Legs. Fore tibia flat, with five spines on external margin ( Fig. 4 A View Fig ); fore femur with a bifid long spine on posterior mesial region of ventral surface; internal and external margins of hind femur smooth, with a simple spine near apex on ventral surface ( Fig. 5 A View Fig ). Scutellum. Triangular, with acute apex; disc dark brown with sparse punctures. Hemelytra. Corium with regularly distributed punctures; clavus with three rows of punctures; membrane hyaline, slightly passing apex of abdomen.

Abdomen. Ventrally convex, and covered by fine hairs.

Male genitalia. Parameres large and broad with acute apex, and three long setigerous punctures on central area ( Fig. 6 A View Fig ).
