Material examined. Chichi-jima Is. — Chichi-jima I., Miyano-hama, 1 ♂ (NSMT-Cr 31543; cb 6.0×cl 4.5 mm), 1♂ (NSMT-Cr 31544; cb 6.9×cl 5.0 mm), 29-VI-1974, Ogasawara Fisheries Center leg .

Remarks. This species is close to Pseudoliomera speciosa (Dana, 1852) , in which the carapace dorsal surface is sharply divided into regions by deep linear furrows. All the regions are thickly covered with pearly granules of good size, and the interregional furrows are filled only with short setae. There are no long setae on the regions, differing from P. lata ( Borradaile, 1902) and some related species (cf. Sèrene, 1984). Pseudoliomera speciosa is otherwise well known by having the brush-like setae surrounding the horny tip of the first ambulatory leg, and readily distinguished from all the congeners due to this feature.

In the male at hand, as the generic features, both chelipeds are short, heavy and similar in shape, each palm is swollen, and the fingers are remarkably short; the outer surface of the palm is roughened with depressed granules and dark-colored for most of the outer surface; the upper and distal parts of the palm, and distal halves of both fingers are whitish.

Distribution. This species is widely distributed in the Indo-West Pacific from the western Indian Ocean ( Serène, 1984, Aldabra; Rathbun, 1911, as Actaea, Salomon and Coetivy ) and the Red Sea ( Klunzinger, 1913, as Actaea nana n. sp.) eastwards to Easter Island ( Rathbun, 1907, as Actaea , type locality), and northwards to Japan ( Sakai, 1939, as Actaea ; Sakai, 1976; Marumura and Kosaka, 2003) and Hawaii ( Edmondson, 1962, as Actaea ). Recently, Maenosono (2018) revised six species from the Ryukyu Islands, with key to the species and good photographs.
