Systematics: Acanthococcus torikurai is similar to Ac. glanduliferus Balachowsky 1933 in having two blunt enlarged setae on each margin of each abdominal segment, only a few enlarged setae on the dorsal abdominal segments, and the enlarged setae on the dorsum tending to get larger anteriorly. However, Ac. torikurai differs from Ac. glanduliferus as follows (contrasting character states in Ac. glanduliferus in parentheses): (i) in lacking small pores on hind legs (having small pores on hind legs); (ii) in lacking spinule on surface of meso- and metacoxae (having spinules on anterior surface of meso- and metacoxae); (iii) in lacking a cauda (having a cauda); (iv) in having different sized dorsomedial setae (dorsomedial setae are all of one size); (v) in lacking capitate ventral setae (having capitate ventral setae).
Structure: Slide-mounted adult female body oval, 2.5 (2.0–2.6) mm long, 1.8 (1.2–1.8) mm wide. Antenna 7 segmented, 282–289 (253–298) μm long. (Tanaka & Kamitani, 2023)
