Systematics: Pseudaulacaspis nishikgi is allied to P. celtis, but is easily distinguishable from it by the characters of the abdominal areas and arrangement of the marginal glands in the pygidium (Kanda, 1941).
Structure: Female scale elongate, straight or curved, narrowed toward front, white, 1.5 mm long. 1st exuviae oval, brown, situated on or extending beyond the anterior end of the 2nd exuviae, which is rather large, circular and blackish or reddish brown. Adult female oblong. Pygidium wider than long, with numerous longitudinal lines on dorsum. Median lobes large, prominent, divergent, contiguous at base, slightly concave at outer margin, inner margin roughly serrate 3 or 4 times, with a spine near the base of each lobe. 2nd lobes small, divided, each lobule entire and tapering on distal part. Inner lobules longer than wide. Outer lobules smaller. 3rd lobes not developed (Kanda, 1941).
