Uroptychus Henderson, 1888: 173 [replacement name for Diptychus A. Milne Edwards, 1880 ]. Remarks. More than 70 species of Uroptychus are presently known from the Indo­West Pacific, of which only four have been reported from Australia : U. brucei Baba, 1986 , from northwestern Australia , U. raymondi Baba, 2000 , from Tasmania , and two species described from off Port Jackson, U. australis ( Henderson, 1885 ) and U. gracilimanus ( Henderson, 1885 ) . Twenty­five species are reported herein, of which 20 are also new to science, and two are new Australian records. Under the account of U. yokoyai n. sp. , Uroptychus latirostris Yokoya, 1933 , described from Japan , is removed from synonymy of U. cavirostris Alcock, 1899 , described from the Andaman Sea. Other than U. brucei from the Northwest Shelf, all known Australian species of Uroptychus are present off southern Australia . Therefore, all species reported herein are illustrated and described or diagnosed. A key to all known Australian species is provided.
