Etymology: Moxostoma: Greek, myxo = to suckle + Greek, stoma = mouth (Ref. 45335); duquesnei: Named after Fort Duquesne, upper Ohio River drainage, Pittsburgh, Pennsylvania; type locality (Ref. 10294).
Eponymy: This is not a true eponym, but is named after Fort Duquesne (now Pittsburgh, Pennsylvania, USA) so actually a toponym. The fort was named after Marquis Duquesne, the governor-general of New France (i.e. the area of North America colonised by the French). (Ref. 128868), visit book page.
