Systematics: Chionaspis agranulata is close to C. lithocarpi, but can be distinguished by the total absence of thoracic granules on the ventral side of the body and by the number and size variation of dorsal macroducts (Chen, 1983). C. agranulata also resembles C. sivapuriana in having squat, broadly rounded median lobes. C. agranulata differs from C. sivapuriana in the basal zygosis of the median lobes not much produced anteriorly, in having many small submedian dorsal ducts on the 2nd to 5th abdominal segments, in the disc pores associated with the anterior spiracle much fewer (4-10), in lacking disc pores at the posterior spiracles, etc (Takagi, 1985).
Structure: Body of adult female elongate, slender. Median lobes stout and plump, wider than long, second lobes very small, but inner lobule pronounced. Dorsal macroducts tend to become smaller from the caudal rows forward (Chen, 1983).
General Remarks: Best description and illustration by Chen (1983).
