Etymology: Acanthurus: Greek, akantha = thorn + Greek, oura = tail (Ref. 45335).
More on author: Valenciennes.
Issue
The species Acanthurus nigros Günther 1861 is considered valid in Eschmeyer (CofF ver. Sep. 2011: Ref. 88002) following Randall & Parenti (2011). But could be an unjustified ementation of nigroris. More studies are needed.
