The background colour of the animal is dark blue-black. There is bright orange-yellow line at the parapodial edge, and a broad light blue band running parallel to the parapodial edge just below the edge. It is separated from the orange-yellow edge by a thin line of blue-black. The rhinopores are also light blue except for the tip which is blue-black. A dorsal patch of blue also occurs on the posterior tip of the foot. The anterior margin of the foot has an orange line.
