Cheilodipterus lineatus Lacepède [ex Commerson] 1802—Large-toothed cardinalfish

Status at New Ireland. New record, based on a specimen photographed at Lissenung Island, Kavieng District, 10 m depth, by Dean Tully on 18 Sept. 2012; a video of a specimen taken at Tungelo Island , off southeastern New Hanover , at 3–46 m depth, St. KR 104, in 2014 (identified by Barry C. Russell).

Remarks. Fricke (1999: 233) treated Centropomus macrodon Lacepede [ex Commerson], 1802 in the synonymy of Cheilodipterus lineatus Lacepède [ex Commerson], 1801, but Gon (1993: 30) and Gon & Randall (2003 a: 32–33) believe that the latter name is unavailable as a secondary homonym of Perca lineata Forsskål in Niebuhr, 1775 . The latter is, however, not an independent species description, but a misidentification of Perca lineata Linnaeus, 1758 , which is now Plectorhinchus lineatus (Linnaeus, 1758) . Cheilodipterus lineatus (sensu Gon & Randall 2003 a: 31–32) is a synonym of Cheilodipterus arabicus (Gmelin, 1789) ; it is restricted to the western Indian Ocean and Red Sea. As both Cheilodipterus lineatus and C. macrodon were frequently used, there is no way to retain C. macrodon , so that the species must be named Cheilodipterus lineatus (see Fricke 2008: 30).

Distribution and habitat. New Ireland: 1, 2.—General distribution: Red Sea, East Africa, Madagascar and Mascarenes east to Marshall Islands and Pitcairn Group, north to southern Japan, south to Western Australia, New South Wales ( Australia), Lord Howe Island, Tonga and Rapa. Solitary in caves and under ledges in lagoon and seaward coral reefs, 0–40 m depth. Marine.
