Nemadactylus

Nemadactylus is a genus of marine ray-finned fish, traditionally regarded as belonging to the family Cheilodactylidae, the members of which are commonly known as morwongs. They are found in the South Atlantic, Indian and South Pacific Oceans.

==Systematics== Nemadactylus was first formally described as a genus in 1839 by the Scottish naval surgeon, arctic explorer and naturalist Sir John Richardson when he described Nemadactylus concinnus which he designated the type species of the new genus by monotypy. Nemadactylus concinnus is now considered to be a synonym of Johann Reinhold Forster's Chichla macroptera. The specific name is a compound of nema meaning "thread" and dactylus which means "finger", a reference to the long rays of the pectoral fins of the type species.
