Labium yellowish brown; apical half of segment IV darkened. Mesoscutum entirely chocolate brown; scutellum yellow, narrowly darkened anteromesally. Thoracic pleura yellowish brown. Hemelytron dark reddish brown; cuneus pale reddish brown, with darker apex; membrane pale smoky brown, semitransparent, with reddish veins. All coxae and legs pale brown, except for apical part of metafemur, base and apex of each tibia, and each tarsomere III dark brown; each tibia partly suffused with red. Abdomen pale brown.

Female: Almost similar to male, except for ovoid body shape.
