Genus Cheilinus: Eight valid species according to ICLARM. Older scientific and pet-fish literature may show Oxycheilinus species placed in this genus.
I like the Europeans choice in common names, "Splendour Wrasses", for this genus and Oxycheilinus over other nationalities "Maori Wrasses" for them, in reference to the colorful "scribbling" on some species faces. Cheilinus labrids are indeed "splendid" all the way around in their color, markings, and graceful movement, but with a few exceptions all are just too BIG for aquarium use. Feeds on benthic invertebrates.
