The type species of Sigalion Audouin & Milne Edwards, 1830 (5. mathildae), Thalenessa Baird, 1866 (S. edwardsi Kinberg, 1856) and Eusigalion Augener, 1918 (E. vazensis) are re-examined. Since they were first described all three genera have been variously misrepresented, but are currently distinguished by the presence (Thalenessa; syn. Eusigalion) or absence (Sigalion) of a median antenna. Material examined in the present study indicates that S. mathildae also possesses a median antenna. Thalenessa and Eusigalion are considered to be junior synonyms of Sigalion and the generic placings of all species attributed to these genera are investigated
