[New Japanese name: Azuki-himehonyadokari]

Pagurixus carinimanus Komai & Osawa, 2006: 71 , figs 29–32, 45B, 48 [type locality: Ankyaba, Amami-oshima, Ryukyu Islands, 1 m].— McLaughlin et al. 2010: 31 (list).—Poupin et al. in press: 44, fig. 23B, C.

Material examined. Kuchino-shima, Tokara Group: stn K 1-1, 29°59.1´N, 129°55.7´E, 7 m, 26 Jul. 2012, coll. T . Kawai, 1 female (sl 1.7 mm), RUMF-ZC 2328 .

Coloration in life. The coloration of the present specimen agrees well with that of P. carinimanus described by Komai & Osawa (2006, fig. 45B). See Fig. 2A .

Distribution. Ryukyu Islands, Guam, the Philippines in the western Pacific, and Mayotte and Glorioso Islands in the western Indian Ocean; depth range 1–30 m ( Komai & Osawa 2006; Poupin et al. in press). Until now, Amami-oshima was the reliable northern-most locality from which P. carinimanus was known ( Komai & Osawa 2006). The present specimen, collected from Kuchino-shima in the Tokara Group, extends the geographical range of the species slightly to the north.

Habitat. Coral reef slope.

Remarks. Although the present specimen lacks the left cheliped and second pereopod (the left third pereopod is not shown in Fig. 2A ), it agrees well with the original description of P. carinimanus in all other morphological characters.
