Material examined. French Polynesia: 1 female (pocl 1.7), FLMNH UF 23275, Moorea, back reef at west corner of Cook’s Bay Pass, -17.4815 -149.8255, backreef, 1–2 m, algal wash, leg. L. Watling, 12.12.2009 [BMOO-10719, BIZ-284]. Hawaii: 1 ov. female (pocl 1.8), FLMNH UF 15204, Maui, Wahikuli Beach Park, 20.9189 -156.6644, Halimeda bed, 6–12 m, algal wash, leg. P. Fiene, 30.11.2008 [G-08-087, Pittman-1081130]; 1 female (pocl 1.7), FLMNH UF 15205, Maui, Wahikuli Beach Park, 20.9189 -156.6644, Halimeda bed, 6–12 m, algal wash, leg. P. Fiene, 30.11.2008 [G-08-088, Pittman-1081130].

Colour pattern. Semitransparent with irregular large white areas on carapace and abdomen (some possibly covering internal organs); isolated patches of red chromatophores present on carapace, e.g., around orbits, and on abdomen, here forming faint red bands; antennular peduncles with small white patch distally; third maxilliped white proximally, greyish-white with red chromatophores distally; first pereiopods mostly white; remaining pereiopods transparent with some red chromatophores; tail fan with large white patches ( Fig. 2 ).

Remarks. The material from Hawaii and Moorea corresponds closely to the description by Hayashi (1975).

Ecology. Although the ecology of this species is still poorly known, it appears to occur in reef-associated environments, e.g., Halimeda beds, lagoon reefs and pools, between low tide mark and 12 m (Hayashi, 1975; present records).

Distribution. This species appears to be widespread in the Indo-Pacific, although it has been only formally recorded from a few scattered localities. Hayashi (1975) provided records of C. molaris from Rongelap and Bikini atolls ( Marshall Islands), Paternoster Island (currently Kepulauan Tengah) ( Indonesia), Eilat (Red Sea) and Kenya. Devaney & Bruce (1987) provided the only further record, from Enewetak Atoll ( Marshall Islands). The present records constitute the first for the species from French Polynesia and Hawaii.
