Remarks
The specimens examined agree well with the original description by Hayashi (1975)[1]. As in Anachlorocurtis occidentalis sp. n., the specimens examined of Anachlorocurtis commensalis vary in the dorsal armament of the carapace and rostrum (Fig. 5G–L). In adult and subadult females the carapace with the rostrum is triple lobate, in contrast in males only the anterior, bidentate, lobe is developed, in addition to the posterior hooked tooth and a short styliform rostrum. In juveniles the posterior hooked is absent and the anterior ornamentation generally consists of a short simple rostrum with a single posterior dorsal tooth. The posterior dorsal submarginal tooth is small in adults and subadults, and is absent in juveniles. The rostral formula (see above) is 2-4 + 4-5 for adult females, 2-3 + 1-2 for subadult females, 2 + 1 (i.e. simple rostrum) for males, and 1-2 + 1 for juveniles. Cornea in males is almost globular, with the apical tubercle indistinct, in females the tubercle is more produced but not as developed as Anachlorocurtis occidentalis sp. n.
Colour in life
Generally similar to that of Anachlorocurtis occidentalis sp. n., but the light transverse bands are greyish, more wide and distinctive in Anachlorocurtis commensalis (Fig. 6D); also see colour photos in Minemizu (1996[5]: 8; 2000[6]: 113; 2013[4]: 129), Kato and Okuno (2000[7]: 58) and Kawamoto and Okuno (2003[3]: 64).
Distribution
Kii Peninsula (type locality), Izu-Oshima and Hachijyo-jima, Izu Islands, and Kume-jima, Ryukyus, Japan (Minemizu 1996[5], 2000[6], 2013[4], Kato and Okuno 2000[7]), Kawamoto and Okuno (2003)[3]; South (Namwan) Bay, Taiwan (present report).
