Cheilodactylus
Cheilodactylus is a genus of marine ray-finned fishes belonging to the family Cheilodactylidae, known as morwongs, although this name is not unique to this family. They are found in the temperate waters of the southern hemisphere and in the North Pacific Ocean. Taxonomy. "Cheilodactylus" was first formally described in 1803 by the French naturalist Bernard Germain de Lacépède when he described "Cheilodactylus fasciatus" which was its type species by monotypy. The traditional delimitation of the families Cheilodactlidae and Latridae is based on morphological differences, but the reliability of these differences has been called into doubt, and a phylogenetic  analyses and genetics have not supported this arrangement. This has led to some authorities suggesting that the majority of species in Cheilodactylidae should be placed in Latridae. A result of this rearrangement is that the only species which would remain in Cheilodactylidae are "Cheilodactylus fasciatus" and "C. pixi" from southern Africa. This is because these analyses resolved the genus "Cheilodactylus" as polyphyletic. These studies appear to show that most of the species in "Cheilodactylus" "sensu lato" instead apparently to belong in several different genera and are not even members of the same family, but how many and their exact delimitation  is not clear at present. The outlier species have been assigned to "Chirodactylus", "Goniistius", "Morwong" and "Pseudogoniistius", but DNA and morphologic analyses found those species to be nested within Latridae and more derived than the kelpfish, marblefish and the "Cheilodactylus" type species "C. fasciatus". The name of the genus is a compound of "cheilos" meaning “lip”, a reference to the thick, fleshy lips of the adults, and "daktylos" which means “finger”, a reference to the elongated lower rays on the pectoral fins. Species. The genus "Cheilodactylus" "sensu lato" includes sixteen species, this list shows the genera they have been assigned  to under the proposed revised taxonomy:
