Material examined. COCOS (KEELING) ISLANDS. ZRC 2021.0638 View Materials , 2 females (sl 2.9, 3.9 mm; larger one photo), CK19, S of Direction Island , 12°05.503′S, 96°52.904′E, 6.9 m, 22 March 2011 GoogleMaps ; QM W29569, 1 female (sl 2.2 mm), CK23, off North Point , 12°07.670′S, 96°51.813′E, 13.1 m, 23 March 2011 GoogleMaps .

Distribution. Widely distributed in the West Pacific: Japan (Ryukyu Islands), the Philippines, Indonesia, Marshall Islands, New Caledonia, and French Polynesia; coral reef, intertidal to 20 m deep ( McLaughlin & Haig, 1984; Komai & Asakura, 1995; Komai & Osawa, 2006; Komai, 2010; Komai & Rahayu, 2013; Poupin et al., 2013).

Remarks. The present specimens agree well with the descriptions of Pagurixus maorus by McLaughlin & Haig (1984), Komai & Asakura (1995), and Komai & Osawa (2006), and confirm the occurrence of this species in Cocos (Keeling) Islands.

Morgan (1992) recorded Pagurixus cf. maorus from Christmas and Cocos (Keeling) Islands, but noted that the dactyli of pereopods 2 and 3 were shorter than the propodi, and the male right cheliped was much less elongate than that illustrated for P. maorus by McLaughlin & Haig (1984). The real identity of the specimens reported by Morgan (1992) needs to be verified.
