Naso tergusis the newest species of surgeonfish which was described from specimens collected around Taiwan. The new Naso species along withAcanthurus nigrosare the two latest additions to the family Acanthuridae. However unlike A. nigros which was differentiated based on genetics, Naso tergus was described based on a distinct body shape and morphology.
台湾Naso tergusis closely related to other unicorn surgeonfish such asNaso hexacanthus和Naso Caesius但是它以细长的头和身体,尾花梗上的圆形叶片和身体上没有独特的标记来区分。小的Naso tergus可以使其成为水族馆的独角兽surgoenfish物种,但是由于原始标本被捕获在70至80米之间(230英尺至260英尺),因此我们不太可能很快在LFS上看到这些标本。Naso tergusis described in the latest issue of The Raffles Journal of Zoology.
