The Hawaiian blackhead triplefin (Enneapterygius atriceps), also known as the Hawaiian triplefin in Hawaii,[2] is a species of triplefin blenny in the genus Enneapterygius.[3] It is a tropical blenny found in coral reefs in the Pacific Ocean, from the Hawaiian Islands, French Frigate Shoals, Laysan Island, and Midway Atoll.[3] Blennies in this species swim at a depth range of 1–23 metres, and inhabit dead coral and rock.

It was originally described by O.P. Jenkins in 1903,[4] as a species of Tripterygion, but was reassigned to Enneapterygius by R. Fricke in 1997.[5]

Description

The Hawaiian blackhead triplefin is considered part of the Enneapterygius hemimelas species group. It is considered a small or medium member of the group,[6] with males reaching a maximum length of 2.6 centimetres.[3] Males can be distinguished from females by their dark head colouring.[6]
