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.

Issue
The original specific epithet is duquesnii but the unjustified emendation duquesnei is in current prevailing usage (see ECoF for nomenclatural details).
