LiuKoRh1989: pp.18 ( Adult (F) ) [Key to the species of Chionaspis in North America]

Systematics: The bark form of C. platani is similar to this species in general appearance, but it has a more pointed apex of the median lobe; also the outer lobule of the third pair of lobe is distinct, and it has so far only been found on Platanus. C. styracis can be told form C. hamoni and C. longiloba by the distinctly different shape of the median lobes, the marginal serrations of all marginal lobes and the reduction of the outer lobule of the third lobe (Liu et al., 1989).
Structure: Test of adult female elongate, oystershell-shaped, white or dirty white, quite small, about 2.1-3.0 mm long and 0.6-1.0 mm wide. Exuviae at pointed end, first instar exuviae light yellow, second light brown, occupying about one fourth of test length. Ventral test white and very thin. Adult female spindle-shaped, distinctly segmented and laterally lobed, broadest at abdominal segment I or metathorax (Liu et al., 1989).
General Remarks: Detailed description and illustration by Liu et al. (1989).
