Distinguishing features

"Adults are blackish with the lower half of the head, chest and belly white, a short white to yellow vertical band above the pectoral-fin base, two broad white to yellow bars on the sides and a yellow tail. The pale areas in females are mostly white, whereas in males these areas tend to be more yellow. Males also have a pale pink chin and filamentous lobes on the tail.

Often confused with the closely related Jansen's Wrasse, Thalassoma jansenii."
