Habitat. Intertidal to shallow subtidal, 0–2 m deep, on hard bottoms (coralline and rocky substrates). Remarks. The name C. elegans previously included the Indo-West Pacific form, with bright blue bands on the pereopods, and the Hawai’ian form, with orange-red banded pereopods ( Haig & McLaughlin, 1984 ; Hoover, 1998 ). However the consistent colour differences, the geographical separation of these two colour forms, and genetic evidence all suggest that they are distinct species ( Malay & Paulay, 2010 , Fig. 9 ). The Hawai’ian form should be properly named C. pictus ( Owen, 1839 ) based on Owen’s (1839) description and colour illustration of specimens collected in Oahu (see also Legall & Poupin, 2016 ).
