Remarks

• Systematics: This species belongs to the rosae type in body shape, having an enlarged prosoma, however, it has also a much broadened postsoma, which makes the whole body appear obovate in outline. It is very similar to Aulacaspis machili which occurs in Taiwan and Japan, The close similarity between these two species may largely be attributed to convergence, but is is also possible that they are really closely related to each other. In eith case, thee species afford another example that dividing the species of Aulacaspis into the typical forms (rosae) and the atypical ones is primarily a matter of convenience and does not necessarily have phylogenetic significance. (Takagi2.013)
• Structure: the adult female about 1400 µm long at maximum, pygidium 290-335 µm long, about 1.5times as wide as long. Prosoma swollen, depressed semicirular in rough (, about 1.5 - 1.7 times as wide as long: no obvious prosomatic tubercles. Postsoma robust; metahorax about 0.8-0.9 times as wide as prosoma, the free abdominal segments gradually narrowing caudad. Dorsal surface of prosoma tending to be scclerotized for a considerable part, with many small sclerotized patches; dorsal surface of prepygidial segments of postsoma with sclerotized patches submedially and submarginally. (Takagi, 2013) The second-instar male is noteworthy in having the ducts mostly deveroped into macroducts ofn both surfaces. (Takagi, 2013)
