Geneion Bibron in Duméril, 1855: 280

Diagnosis provided, thus an available name. A single included species, thus type species by monotypy: Tetraodon (Geneion) maculatum Bibron in Duméril, 1855. Gender: neuter.

The specimen recorded as holotype of T. maculatum by Le Danois (1962: 470) is conspecific with T. honckenii Bloch, 1785 , which is the type species of Amblyrhynchote Bibron in Duméril, 1855. This makes Amblyrhynchote and Geneion simultaneous subjective synonyms and precedence among these names is fixed by the first reviser. The first reviser is apparently Le Danois (1959: 185) who used Geneion as the valid name and listed “ Amblyrhynchotus (pars) Bibron (Duméril)” (treated here as an incorrect subsequent spelling of Amblyrhynchote ) in its synonymy. On p. 171, she also treated “ Amblyrhynchotus Bibron ” as a valid genus, with an erroneous type species; this apparently has no implication on the validity of the precedence established on p. 185 (if Le Danois’s action cannot be recognised as a first reviser action, then Shipp [1974: 19] is the first reviser as he stated: “ Le Danois [1959: 189] […] synonymized Geneion maculatum with Geneion honckenii (Bloch) and thus considers Geneion as the genus to represent this latter species rather than Amblyrhynchotes […]”).
