Systematics: Nikkoaspis sikokiana is similar to N. shiranensis, but differs from the latter in the marginal gland spines longer than the plates and projecting beyond the apices of the latter throughout the 3rd to 5th abdominal segments and pygidium. In N. shiranensis the marginal gland spines, except those occurring just laterally to the median and 2nd lobes, are as long as or shorter than the plates (so that they may easily be overlooked when overlapping with plates). Furthermore, N. sikokiana is usually provided with 2 plates between the median and 2nd lobes, whereas N. shiranensis with one plate and only rarely with two in this space (Takagi, 1999a).
Structure: Female scale white, convex dorsally. Male scale felt-like, tricarinate dorsally. Adult female body 1.7 mm long, pyriform, broadest across base of abdomen; prepygidial segments little lobed laterally (Takagi, 1999a).
Biology: This species was collected at an altitude of 1000m (Takagi, 1999a).
General Remarks: Detailed description and illustration by Takagi (1999a).
