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.

Chelidoperca cerasina sp. 11 月,来自西南太平洋的新鲈鱼(鲈形目:鲽科)

新的 serranid 鱼 Chelidoperca cerasina 是根据来自珊瑚海(新喀里多尼亚和澳大利亚东部),西南太平洋,深度为 245-338 m 的 13 个标本进行描述的。通过具有以下特征组合,可以很容易地将新物种与所有同类区分开来:胸鳍和尾鳍基部有一个橙色斑点;侧线与棘背鳍基部之间有4排鳞片;8 或 9(模态 8)行的脸颊鳞片;上尾鳍叶的尖端拉长,在标本中略长于下叶 > 约。100 毫米;体侧无纵向黑色条纹或一排黑色斑点;眶间鳞片延伸超出眶中水平,但未达到眶前缘;下颌腹面的鳞片仅限于有棱角的,在牙齿上无;腹鳍短,
