Remarks
- Systematics: Pallulaspis quercus is unique in the presence of a lateral tubercle and a gland spine on the prepygidial segments (Takahashi, 1957b). After repeated observations of the type slides by Takagi, he determined that the type described by Takahashi was a second-instar nymph and not an adult female. He compared these specimens with second-instar nymphs of Lepidosapes glaucae and found "no appreciable difference between them. However, he declined to formally synonymize the two, stating that "the agreement of characters in this instar does not necessarily mean that the two forms are identical."
- Structure: Female scale moderately broadened posteriorly, convex on the median area, dark purplish brown, gray on the margin, 2.5 mm long. Adult female body almost parallel on the sides, scarcely convex laterally on the prepygidial segments, about 2.5 times as long as wide, not sclerotized (Takahashi, 1957b).
- General Remarks: Detailed description and illustration by Takahashi (1957b).
