Systematics: Aulacaspis robusta is close to A. kadsurae, but may be distinguishable from the latter by having more numerous gland spines on the 3rd and 4th abdominal segments; the dorsal macroducts are also generally more numerous in A. robusta (Takagi, 1970).
Structure: Adult female scale subcircular or broadly oval, somewhat convex, greyish or pale brownish white, about 3-3.5 mm in length, about 2.5mm in width. Larval skins near the margin, pale yellowish brown (Takahashi, 1931a). Adult female at full growth robust; prosoma distinctly broader than postsoma, broadest subbasally; prosomatic tubercles low and roundish; peribuccal scleroses well formed. Anterior spiracles each with a large group of disc pores; posterior spiracles each with disc pores in irregular clusters. Perivulvar disc pores numerous. In the Taiwan form, the prosoma is much broadened subbasally, about 1.5–1.7 times as wide as long and nearly half-circular in outline, the metathorax is also remarkably broadened, and the whole postsoma gradually narrows posteriorly. In the Borneo form, the prosoma is less broadened, about 1.3–1.4 times as wide as long and roughly quadrate in outline, the metathorax is not particularly broadened, and the prepygidial postsomatic segments are nearly the same in width.
