Systematics: Pseudaulacaspis taiwana is close to P. kinshinensis, but differs as follows: larval exuviae pale yellow, with no ridge on 2nd; pygidium narrower, nearly as long as wide, with fewer dorsal orifices and circumgenital pores, with no median gland (Takahashi, 1935).
Structure: Female scale snowy white, flattened, thin, expanded towards the hind margin, nearly triangular, longer than wide, broadly rounded on the hind margin, about 1.6 mm long, without striae and ridges on the secretion. Larval exuviae pale yellow, at the anterior end of the scale, 2nd exuviae slightly covered with secretion, lacking ridges, about twice as long as wide, about 0.785 mm long. Adult female body parallel on sides. Pygidium slightly wider than long, not more sclerotic than other parts of body, with many longitudinal dorsal lines (Takahashi, 1935).
General Remarks: Best description by Takahashi (1935).
