Sterletus (subgenus of Acipenser) Rafinesque [C. S.] 1820:248 Masc. Accipenser serotimus Rafinesque 1820. Type by subsequent designation. Also appeared in Rafinesque 1820:80 (Dec.) [ref. 3592]. Type designated by Jordan & Gilbert 1877:87 [ref. 4907] as Accipenser sterletus in error, first species mentioned is Accipenser serotimus. Jordan 1917:113 [ref. 2407] has Acipenser serotinus Rafinesque 1820 as type. Rafinesque's use of the spelling Accipenser for the subgenus is an unjustified emendation or misspelling. Huso is now in usage, so it seems problematic to use Sterletus for the genus. For the time being we are not following Kottelat & Freyhof 2025 [ref. 42352]. •Synonym of Acipenser Linnaeus 1758. •Synonym of Huso Lovetsky 1834. •Valid as Sterletus Rafinesque 1820 -- (Kottelat & Freyhof 2025:541 [ref. 42352]). Nomen Oblitum. Current status: Synonym of Huso Lovetsky 1834. Acipenseridae.
