Systematics: This species can be distinguished by its highly chitinised anterior half of the body and its remarkable distortions (Newstead, 1917). Hall (1929) states that Brain lists Asymmetraspis distorta as a synonym of Chionaspis distincta, but that the two species are obviously distinct.
Structure: Female puparium white, elongate, gibbose anteriorly, attenuated posteriorly; more or less straight, curved or contorted. Larval pellicle apical, dull red-brown, buff-yellow or sometimes dull crimson, margin generally paler; secretionary covering thin, white. Adult female more or less elongate; cephalothoracic area highly convex, generally distorted, asymmetrical and highly chitinized (Newstead, 1917).
