The family Serranidae is represented by 92 genera and 579 valid species, with the genus Cuvier, 1816, containing 30 species. In this study, specimens of Butterfly-winged Comber, Valenciennes, 1832, were collected from the Canary Islands and compared morphologically and genetically to Painted Comber, (Linnaeus, 1758), from the Mediterranean Sea. Morphological differences, especially in the colour banding pattern, were corroborated by genetic differences in mitochondrial (COI and ND2) and nuclear (Rhod and PTR) markers. The mitochondrial DNA markers revealed a high level of divergence and no shared haplotypes between the two species (interspecific divergence: COI 4.31%; ND2 8.68%), and a phylogenetic analysis showed that these two species are closely related sister species sharing common ancestry. This study is therefore offering to resurrect Valenciennes, 1832 as a valid species increasing the number of eastern Atlantic species to 11. This should direct new species-specific research, including its population conservation status assessment across its distribution.
鮨科有92个属和579个有效物种,其中居维叶属(1816年)包含30个物种。在本研究中,1832年命名的蝴蝶翼梳齿鲈标本采集自加那利群岛,并与来自地中海的1758年命名的斑纹梳齿鲈进行了形态学和遗传学比较。线粒体(COI和ND2)和核(Rhod和PTR)标记的遗传差异证实了形态学差异,尤其是在色带模式方面。线粒体DNA标记显示这两个物种之间存在高度分化,且没有共享单倍型(种间分化:COI为4.31%;ND2为8.68%),系统发育分析表明这两个物种是密切相关的姊妹物种,有着共同的祖先。因此,本研究提议将1832年命名的蝴蝶翼梳齿鲈恢复为有效物种,使东大西洋物种数量增加到11种。这应为新的物种特异性研究指明方向,包括对其分布范围内的种群保护状况进行评估。
