Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 14 - 15; Rayons mous dorsaux (Total) : 15 - 16; Épines anales: 3; Rayons mous anaux: 16. This species is distinguished by the following characters: colour of live individual is lemonpeel yellow with blue margined gill operculum, spine and fins; conspicuous blue iris and faint blue eye ring surrounding the eye; colour in alcohol is uniformly yellowish with dark eye and dark posterior dorsal, anal and caudal fin margins; differs from C. flavissima (and 2 other species of this specis complex) by nucleotide quasisynapomorphies at the CO1 locus, these include G at both nucleotide sites 247 and 366 of the gene (Ref. 116591).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Occurs in coral-rich areas of lagoons, passages, and seaward reefs. Small groups consist of several females and a dominant male (Ref. 137463).
