[2] The genus Acanthurus is one of two genera in the tribe Acanthurini, which is one of three tribes in the subfamily Acanthurinae. [3]

Acanthurus leucocheilus has its dorsal fin supported by 9 spines and 24 or 25 soft rays, while the anal finis supported by 3 spines and 23 soft rays. [5] The overall colour of this fish is brown or blackish, with light coloured lips and a white band across the throat. The spine on the caudal peduncle is white and has a white bar around it. The pectoral fin has a white bar on its distal part. When feeding, the fish may be paler than at other times. Juveniles are brown and have a yellow tail. [6] This species has a maximum published standard length of 45 cm (18 in). [5]

It occurs on the coast of eastern Africa between Djibouti and northern Mozambique, the Seychelles, Maldives, Sri Lanka, Andaman Islands, Nicobar Islands east to Tuvalu and the Line Islands, including Christmas Island in Australia.
