Systematics: Aulacaspis formosana is close to Phenacaspis fujicola, but differs in the basal abdominal segment lacking lateral glands as large as those on the posterior segments and in the 3rd abdominal lobes distinct. Differs also from P. varicosa in lacking gland spines on the basal abdominal segment and in the shape of the 2nd and 3rd lobes, as well as in the median lobes roughly serrate (Takahashi, 1934).
Structure: Female scale white, thin, semitransparent, oval or nearly circular, very slightly convex, about 1.5 mm long. Larval skins pale brownish yellow, extending beyond the front margin of the scale (Takahashi, 1934).
General Remarks: Best description and illustration by Takahashi (1934).
