The genus name is a compound of picti meaning "painted" and labrus which is the type genus of the wrasse family, Labridae, and may derive from the Greek labrax meaning a specific type of fish. The specific name refers to the blue spots on the fins which Richardson considered to resemblethe clavi on the borders of the Roman patrician clothing.
