Description: Males have a face that is distinctly bowed in profile, and the pronotum is arched and strongly declivous anteriorly. Males are ferruginous, with the face marked black on the lower half; the legs are tawny yellow. The tegmina is a deep ferruginous in the males, darker along the costa, the crossveins, the apex, and along the commissure between the pale markings/spots. Females have a weakly bowed face that recedes in profile. Females are ferruginous overall, being darker on the scutellum; sometimes they have a fuscous band across the pleura. The legs are pale ferruginous to tawny yellow and are conspicuously banded, with the femora being ferruginous, chocolate-brown, or blackish-brown color. The tegmina is similar to the male's, but paler and semihyaline ferruginous; usually it is not as dark on the costa compared to the male. The female pregenital sternite is semicircular to quadrate, and is usually infuscated along the margins. Adult males are 4.6 to 4.9 mm long, while females are 4.7 to 5.0 mm. (Hamilton 1983)

Nymphs of this species are ferruginous, with the base of the abdomen paler. (Hamilton 1983)
