Head yellow with antenna (excluding arista) paler excluding brown spot at base of arista, ocellar tubercle brown with spot extending onto dorsomedial margin of back of head, face, occiput and parafacial light yellow, and gena white and silvery-tomentose. Notum dark brown with postpronotum, anterior margin of scutum and thin line down center of scutum (not attaining posterior margin) yellow. Pleuron and legs yellow.
