Remarks

• Systematics: Aulacaspis yabunikkei is so similar to A. tubercularis that records of either species on Lauraceous plants may be open to criticism (Takagi, 1970). Takagi (2014) separated the yahunikkei complex of Aulacaspis occurring in Japan into three different species on the absis of the host plants, the body shape at full growth, and the median trullae. They are (A yahunikkei and two new species A neolitseae and A. sirodamo. The published descriptions and records made under the name A. yahunikkei should be revised from this new viewpoint, and a careful study is required. It is not knowable whether the records from other areas of Asia included forms corresponding to the revised concept of the species. (Takagi, 2014)
• Structure: Female scale circular, flat or slightly convex opaque white. Exuviae subcentral or marginal; first exuviae pale with yellowish brown caudal end. Ventral scale thin, white. Male scale small, narrow, sides nearly parallel, white, distinctly tricarinate (Kuwana, 1926). In the 2014 revision of the "yahunikkei" complex, Takagi described the body of the fully grown adult female as "attaining about, or somewhat more than, 1000µm in length; of the rosae type in shape; prosoma moderately swollen, about 0.5 times as wide as body length, roundish along free margin, or rather quadrate with lateral margins behind prosomatic tubercles straight; prosomatic tubercles slightly produced or merged into general outlline of prosoma; propygidial portsoma with lateral sides subparallel;"..."Second and third trullae with lobules well developed and a little dilated."
• Biology: In the 2014 revision of the "yahunikkei" complex, Takagi stated that this species is associated with CInnomomum japonicum and, in southern Japan, occasionally also with other species of Connomomum.
• General Remarks: Detailed description and illustration by Takagi (1970).
