  Maskell (1897a) states that Aulacaspis spinosa differs from A. rosae by being browner in color and having more numerous spines on the abdomen. In the Japanese form of this species the prosomatic tubercles are completely lacking, whereas in the Taiwanese form these tubercles are usually more or less pronounced, agreeing with the form described by Scott (1952). Since there is no other distinct difference between the two forms, the Taiwanese form may be included within A. spinosa (Takagi, 1970). The description of Diaspis rosae var. spinosa Maskell states that this scale insect, occurring in Japan on Smilax, has numerous spines; it gives no further clues for recognizing the insect. Samples of Aulacaspis collected on Smilax have been available from 23 localities in Japan, and some hundreds of adult females mounted from them have been examined. Takagi, 2016, states that he has have no doubt that all these specimens belong to one and the same species and that this species is identical with Maskell’s D. rosae var. spinosa, which has been treated as Aulacaspis spinosa since Kuwana (1926).
