Etymology: Goniistius: Greek, gonio = angle (Ref. 45335); francisi: Named for Malcolm Francis, for contributions made to biogeography of SW Pacific fishes.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 6 - 88 m (Ref. 76788). Subtropical
Pacific: Lord Howe Is., Lord Howe Rise, Middleton Reef, and the Kermadec Is.; probably misidentified as C. vittatus from New Caledonia and Norfolk I., based on live photographs, and Elizabeth Reef on visual observations.
