The body of this nudibranch is mostly transparent white in colour with cream coloured organs showing through the skin. There is a band of dark pigment along the midline of the back and extending into the inner surfaces of the rhinophore sheaths and a similar area of dark pigment on the inner faces of the cerata. Each ceratal tubercle is covered with a dark pigment patch, except for the elongate terminal tubercle which is transparent, showing white glandular bodies concentrated below the surface.
