Very similar externally to Runcina coronata. The body is dark, almost black with a two pale yellow areas, one on each side of the head. The posterior end of the notum is also translucent colourless. There is a dark, almost black, median band on the posterior end of the foot, the edges being a translucent yellow. Cervera et al (1991) discuss how many authors have confused this species with Runcina coronata.
