Systematics: Chionaspis gilli is close to C. etrusca, but can be told from it as follows: in C. gilli, the median lobes are elongate and narrow, strongly divergent, poorly sclerotized, without, rarely with, irregular notches on both mesal and outer margins, and with 2 gland spines and 1 long seta just overlapping with the median lobes, and protruding distinctly beyond the apex of pygidium; further, in the second pair of lobes only the inner lobule is distinct and elongate, and the outer lobule is reduced to very small projections; while in C. etrusca, the median lobes are well developed, short and broad, conspicuous, notched on both inner and outer margins, straight and rounded apically, and the gland spines and setae beside the median lobes are not as long as those in the new species (Liu & Kosztarab, 1987).
Structure: Scale of adult female very similar to that of C. etrusca, oystershell-shaped or pear-shaped, white or dirty white, about 1.6-2.5 mm long, terminal exuviae yellowish brown, occupying about one third of total length of test. Ventral test thin, adheres to surface of host when dorsal test is removed (Liu et al., 1989).
General Remarks: Detailed description and illustration by Liu et al. (1989).
