Chelidoperca cerasina sp. nov., a new perchlet (Perciformes: Serranidae) from the southwest Pacific Ocean


The new serranid fish Chelidoperca cerasina is described on the basis of 13 specimens from the Coral Sea (off New Caledonia and eastern Australia), southwest Pacific Ocean, at depths of 245–338 m. The new species can be readily distinguished from all congeners by having the following combination of characters: an orange spot on pectoral-fin and caudal-fin bases; 4 scale rows between lateral line and base of spinous dorsal fin; cheek scales in 8 or 9 (modally 8) rows; tip of upper caudal-fin lobe elongated, slightly longer than lower lobe in specimens > ca. 100 mm; no longitudinal dark stripe or row of dark blotches laterally on body; interorbital scales extending beyond mid-orbit level, but not reaching anterior margin of orbit; scales on ventral surface of lower jaw restricted to angular, absent on dentary; pelvic fin short, tip not reaching anus when adpressed.
