The barnacle Linnaeus, 1758 (Scalpellomorpha, Lepadidae) is a worldwide distributed species. For investigating its genetic diversity in the northwest Pacific, two complete mitochondrial genomes were determined and analyzed. The lengths of the two complete mitogenomes were 15,708 bp and 15,703 bp, respectively. Both of them contained typical 37 genes with an identical order to Linnaeus, 1767 and Darwin, 1851 mitogenome. Except for and , 11 protein-coding genes (PCGs) started with an ATN initiation codon (ATA, ATG, ATC, and ATT). Twelve PCGs were terminated with TAA or TAG stop codon, whereas possessed an incomplete termination codon (T-). Phylogenetic analysis revealed that and clustered together, and then with . The distinct genetic distances (0.17) based on concatenated sequence of 13 PCGs between the two mitogenomes of suggest the existence of cryptic speciation. Additional samples from multiple localities should be collected and analyzed to deepen the understanding of cryptic diversity within the northwest Pacific.
茗荷属（1758年林奈命名，茗荷目，茗荷科）是一种分布于全球的物种。为研究其在西北太平洋的遗传多样性，测定并分析了两个完整的线粒体基因组。这两个完整线粒体基因组的长度分别为15,708 bp和15,703 bp。它们都包含典型的37个基因，其排列顺序与1767年林奈和1851年达尔文的线粒体基因组相同。除了[此处原文缺失基因名称]和[此处原文缺失基因名称]外，11个蛋白质编码基因（PCGs）以ATN起始密码子（ATA、ATG、ATC和ATT）起始。12个PCGs以TAA或TAG终止密码子终止，而[此处原文缺失基因名称]具有不完全终止密码子（T-）。系统发育分析表明，[此处原文缺失物种名称]和[此处原文缺失物种名称]聚在一起，然后与[此处原文缺失物种名称]聚在一起。基于13个PCGs串联序列的两个[此处原文缺失物种名称]线粒体基因组之间明显的遗传距离（0.17）表明存在隐存物种形成。应从多个地点收集并分析更多样本，以加深对西北太平洋隐存多样性的理解。
