Diagnosis

Body length 1.2–2.4. Pronotum about as long as median head length, slightly narrower than head width. Hemelytron ( Fig. 1F ) generally pale, with four indistinct, broken longitudinal brownish stripes.

Males: fore femur with a row of seven spines in proximal and middle third; fore tibia with three spines distally; palar claw narrow, apical part slightly recurved. Median lobe of sternite VII with two long setae and a pointed apex. Free lobe sub-rectangular, posterior margin nearly straight, angles rounded, lateral angle with ca eight long setae ( Fig. 3D ). Left paramere: shaft styliform, apical part slightly constricted

but not twisted ( Fig. 3F ). Right paramere: shaft evenly curved, from distal fourth tapering towards narrowly rounded apex ( Fig. 3E ).
