Lateral areas of face, pronotum, basal triangles of scutellum, darker; vertex reddish brown; two nearly contiguous irregular transverse bands anteriorly on head, area between inner margin of eye and clypeus, disc of scutellum, a large patch on clavus, yellowish white; clypellus dark brown apically; fore and mid legs pale yellow; forewing with some pale areas in distal cells. Male genitalia: lateral internal pygofer process elongate, strongly upturned apically, tapered to apex. Paramere with straight digitate apical process, tapered to apex; inner margin subapically with small heel-like process and large, strongly upturned, apically crenulate process, separated by a hyaline band.
