Etymology. Gender masculine. Derived from the Greek cheilos (lip) for the fleshy lips of these species, and daktylos (finger) for the lower, unbranched pectoral fin rays.

Inclusive species. Cheilodactylus fasciatus Lacépède (type species), C. pixi Smith

Diagnosis. As per family diagnosis.

Habitat and distribution. Both C. fasciatus and C. pixi occur in cooler waters from Namibia, to Natal, South

Africa. These species can be found in shallow, coastal rocky habitats and are common to 30m depth. However, both C. fasciatus and C. pixi have been observed at 97m and 120m, respectively ( Smith & Heemstra 1986). These species generally stay close to the benthos where they hide among rocks and other rubble ( Smith 1980). Tidepools are thought to be an important nursery habitat for juvenile C. fasciatus in South Africa ( Beckley 1985).

Comments. These species range in size from 180mm for C. pixi , to 300mm for C. fasciatus ( Smith 1980) . Both species are primarily benthic invertivores ( Smith & Heemstra 1986, Griffiths & Lechanteur 2003).
