Northernmost Record of the Surgeonfish Acanthurus nigros (Teleostei: Acanthuridae) from Minamidaitojima Island, Southern Japan

Abstract

A single specimen of surgeonfish (116.1 mm standard length) was collected from Minamidaitojima Island, southern Japan, and identified as Acanthurus nigros Günther, 1861 on the basis of morphological and genetic analyses. This specimen represents the northernmost and westernmost record of the species, about 1500 km from the nearest island (Pagan Island, Northern Mariana Islands) with previously confirmed record for this species. The new standard Japanese name “Nangoku-kurohagi” is proposed herein.
