The wings are hyaline to slightly whitish, with pale veins, and the species is usually brachypterous.  Males are distinctive, with a deep semi-circular groove in the end of the genital segment, seen in side view; they have a black scutellum with a small white tip, and also some black markings at the anterior sides of the pronotum. Females are paler, with a mottled brown/white abdomen and dark-margined keels on the frons.
