Butterfly-winged comber, Serranus papilionaceus Valenciennes, 1832, was recently resurrected and so it is no longer considered as a junior synonym of the Painted comber, Serranus scriba (Linneus, 1758). This calls for a more comprehensive phylogenetic assessment using mitochondria DNA genomes to better understand the relationship and delineate these two species.
Next-generation Sequencing was applied to sequence the genome of these two Serranus species. The data generated was then used to construct the mitochondrial genome of these two species. This produced the first complete mitochondrial genomes for the genus Serranus here represented by Serranus papilionaceus and Serranus scriba. These two mitochondrial genomes are 16,514 bp and 16,512 bp respectively, and both contained the typical 37 genes found in vertebrates (13 protein-coding genes, two ribosomal RNAs, 22 transfer RNAs), together with the O and the control region.
These mitochondrial genomes provide a new insight into the phylogenetic and evolutionary connections between the various subfamilies within Serranidae, while providing new molecular data that can be applied to discriminate between the studied species.
蝴蝶翅鲷， Serranus papilionaceus Valenciennes，1832 年最近被重新发现，因此不再被视为彩绘鲷， Serranus scriba (Linneus，1758) 的次同物异名。这需要使用线粒体 DNA 基因组进行更全面的系统发育评估，以更好地了解这两个物种之间的关系并对其进行划分。
下一代测序被应用于对这两个 Serranus 物种的基因组进行测序。然后，使用生成的数据构建了这两个物种的线粒体基因组。这产生了第一个完整的 Serranus 属线粒体基因组，由 Serranus papilionaceus 和 Serranus scriba 表示。这两个线粒体基因组分别为 16514bp 和 16512bp，均包含脊椎动物中发现的典型 37 个基因（13 个蛋白质编码基因、两个核糖体 RNA、22 个转移 RNA），以及 O 和控制区。
这些线粒体基因组为 Serranidae 内部各亚科之间的系统发育和进化关系提供了新的见解，同时提供了可用于区分研究物种的新分子数据。
