Hello friend. You seem to be mistaken. My description as Acipenser transmontanus is correct and valid according to the Integrated Taxonomic Information System. www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=161068#null

@DeepMarineScenes, not anymore, the Acipenser genus is polyphyletic and the only two extant species constituting the genus are now the Common Sturgeon (Acipenser sturio) and the Adriatic Sturgeon (Acipenser naccarii) whereas the other fifteen extant species are relocated to four separate genera, which are Sterletus for the Diamond Sturgeon (Sterletus gueldenstaedtii), the Sterlet Sturgeon (Sterletus ruthenus), the Thorn Sturgeon (Sterletus nudiventris), the Starry Sturgeon (Sterletus stellatus), and the Persian Sturgeon (Sterletus persicus), Sinosturio for the Chinese Sturgeon (Sinosturio sinensis), the Yangtze Sturgeon (Sinosturio dabryanus), the Green Sturgeon (Sinosturio medirostris), and the Japanese Sturgeon (Sinosturio schrenckii), Altaicosturio for both the Siberian Sturgeon (Altaicosturio baerii) and the Sakhalin Sturgeon (Altaicosturio mikadoi), and Antaceus for the White Sturgeon (Antaceus transmontanus), the Lake Sturgeon (Antaceus fulvescens), the Sharpnose Sturgeon (Antaceus oxyrinchus), and the Shortnose Sturgeon (Antaceus brevirostrum) In fact, these four separate genera are actually believed to be more closely related to the genus Huso that contains both the Beluga Sturgeon (Huso huso) and the Kaluga Sturgeon (Huso dauricus) than they are to the genus Acipenser, with the genera Sinosturio, Altaicosturio, and Antaceus being more derived than Huso but Sterletus being more derived than Acipenser while being basal to the Huso + (Sinosturio + (Altaicosturio + Antaceus)) clade.

@DeepMarineScenes and @mizmastermike2128, there are now eight extant genera of sturgeons (family Acipenseridae) For the subfamily Scaphirhynchinae (Shovelnose Sturgeons), there are two extant genera: Pseudoscaphirhynchus for Syr Darya Sturgeon (Pseudoscaphirhynchus fedtschenkoi), the Dwarf Sturgeon (Pseudoscaphirhynchus hermanni), and the Amu Darya Sturgeon (Pseudoscaphirhynchus kaufmanni) and Scaphirhynchus for the Hackleback Sturgeon (Scaphirhynchus platorynchus), the Pale Sturgeon (Scaphirynchus albus), and the Alabama Sturgeon (Scaphirhynchus suttkusi) For the subfamily Acipenserinae (True Sturgeons), there are six extant genera: Acipenser for the Common Sturgeon (Acipenser sturio) and the Adriatic Sturgeon (Acipenser naccarii), Sterletus for the Diamond Sturgeon (Sterletus gueldenstaedtii), the Sterlet Sturgeon (Sterletus ruthenus), the Thorn Sturgeon (Sterletus nudiventris), the Starry Sturgeon (Sterletus stellatus), and the Persian Sturgeon (Sterletus persicus), Huso for the Beluga Sturgeon (Huso huso) and the Kaluga Sturgeon (Huso dauricus), Sinosturio for the Chinese Sturgeon (Sinosturio sinensis), the Yangtze Sturgeon (Sinosturio dabryanus), the Green Sturgeon (Sinosturio medirostris), and the Japanese Sturgeon (Sinosturio schrenckii), Altaicosturio for the Siberian Sturgeon (Altaicosturio baerii) and the Sakhalin Sturgeon (Altaicosturio mikadoi), and Antaceus for the White Sturgeon (Antaceus transmontanus), the Lake Sturgeon (Antaceus fulvescens), the Sharpnose Sturgeon (Antaceus oxyrinchus), and the Shortnose Sturgeon (Antaceus brevirostrum)
