Diagnosis

Body length 2.2–2.9. Pronotum longer than median head length. Dorsum generally yellowish brown. Hemelytron with four interrupted, longitudinal, brown stripes; embolium with four black spots ( Fig. 21A ).

Males: fore femur with a pair of spines on proximal third ventrally, four spines on distal third; fore tibia with two spines on distal third ventrally; palar claw widened distally, apex rounded. Median lobe of sternite VII and free lobe ( Fig. 22A ) as in diagnosis of subgenus. Left paramere: shaft relatively thick, with sickle-shaped apex, mesial side before apical part covered with small scales ( Fig. 22C ). Right paramere: shaft long and slender, gently curved at distal third and tapering from there towards a narrowly rounded apex ( Fig. 22B ).
