Adult Longfin Bannerfish have a long tapering dorsal filament. The body is white with two broad black bands. The soft dorsal and caudal fins are yellow.
The species grows to 25 cm in length.
The Schooling Bannerfish, Heniochus diphreutes, looks very similar, but can be distinguished by a more rounded profile under the head and a shorter snout. The second black band is located further forward on the anal fin and there is an additional dorsal fin spine (12 vs 11).
It occurs throughout the tropical Indo-West and Central Pacific. In Australia it is known from south-western Western Australia, around the tropical north, and south to the southern coast of New South Wales.
