description |
Males are very dark overall in coloration. They have a yellow venter, tawny to ferruginous legs, and a pale yellowish face that contrasts with a bold but narrow fuscous to black transverse band between the eyes and another on the margin of the head. The pronotum is yellowish with dark speckling, the scutellum is dark. The wings are a deep brown to black with a pale spot along the commissure (inner edge of the wings) near the apex. Females come in several color forms/phases, typical of members of Oncopsis. In Phase D (52% of females), the head, pronotum, and scutellum are yellow, contrasting with ferruginous tinted wings. Phase C (0.5%) is similarly colored but has darker ferruginous markings on the wings. In the second most common form, phase B (41%), the scutellum and pronotum are a bold ferruginous color that contrasts with a yellow head; the wings are largely ferruginous with a whitish V-shaped mark in the middle [of the back] and two clear "windows" closer to the apex. In phase D (7%), the females are colored similar to brown males but have a face that is more or less ferruginous. The female pregenital sternite has a prominent to very small notch on the posterior margin. Adult males are 4.9-5.9 mm long, while females are 5.1-5.9 mm. (Hamilton 1983)
Nymphs are ferruginous with a white, pale tip to the abdomen that contrasts with the darker rusty base of the abdomen. |

This species is similar to O. sobria, specifically the males. The nymphs of citra are distinctive in coloration among members of this genus. (Hamilton 1983) |
