Synaptura
Synaptura is a genus of soles. Most species are found in salt and brackish water in the Indo-Pacific and tropical East Atlantic, but S. salinarum is restricted to fresh water in Australia. The largest species in the genus reaches a length of.
Paul Chabanaud retained the genus named Synaptura for this group and he designated Pleuronectes commersonnii as its type species. This designation is incorrect according to the International [Code of Zoological Nomenclature] and Synaptura as designated by Theodore [Edward Cantor] is a synonym of Brachirus. Due to this some workers have assigned the species previously assigned to Synaptura, as raised by Chabanaud to Dagetichthys, a previously monotypic genus which contained just Dagetichthys lakdoensis. This more broadly defined Dagetichthys for a monophyletic clade. Buglossidium luteum seems to be the most closely related taxon to Dagetichthys.
