Physogaster (subgenus of Tetrodon) Müller [J.] 1841:252 Fem. Tetrodon oblongus Bloch 1786. Type by subsequent designation. Two species (oblongus and lunaris) mentioned; earliest subsequent designation perhaps is Bleeker 1865:46 [ref. 416] through objective synonym Gastrophysus; Jordan 1919:196 [ref. 2410] lists lunaris as type. Apparently preoccupied, replaced by Gastrophysus Müller 1832. Kottelat 2013:476 [ref. 32989] says "Gastrophysus has been used as a valid name after 1899 and therefore precedence over Takifugu cannot be reversed under Code art. 23.9; not junior homonym of Gastrophysa Dejean, 1835: 405 (nomen nudum) and Gastrophysa Gebler, 1842: 39 in Coleoptera". For stabilization, we prefer to use Takifugu for the time being. •Synonym of Lagocephalus Swainson 1839 -- (Shipp 1974:17 [ref. 7147]). •Synonym of Takifugu Marshall & Palmer 1950 based on placement of type species. Current status: Synonym of Takifugu Marshall & Palmer 1950. Tetraodontidae.
