Systematics: In the shape of the median lobes, the number and arrangement of the dorsal macroducts and other features this species is similar to the leaf-form of Chionaspis linderae, which occurs in Japan on deciduous Lauraceae. It differs from the latter in having definitely more numerous perivulvar disc pores (total 85-121 in C. clematidis; 37-65 in the leaf form of C. linderae, n=38), and also more numerous spiracular disc pores (in the leaf-form of C. linderae the anterior spiracle with 3-15 disc, n=42, and the posterior spiracle with 1-5, n=72). Further, in the leaf form of C. linderae the inner lobule of the 2nd lobe extends posteriorly beyond the apices of the median lobes, and the outer lobule of the 3rd lobe is reduced to marginal serrations (Takagi, 1985).
Biology: Chionaspis clematidis was collected at an altitude of 540 meters (Takagi, 1985).
