为了揭示日本四种沿海虎甲(Lophyridia angulata、Abroscelis angoralis、Cicindela lewisii和Chaetdera laetescripta)的系统发育模式，利用COI和16S rRNA两个基因座的线粒体DNA序列进行了系统发育和巢式分支分析(NCA)。Abroscelis angulata和Abroscelis angulata在日本有相似的间断分布。NCA表明，过去的碎片化涉及到三个孤立的锚状棘豆区域。与之相反，日本的地方群体共享相同的单倍型，这表明最近发生了变异。几个不同分支的单倍型在日本种群中的共生。莱特斯克里塔暗示了远古的替代和随后的当地种群的混合。柳杉的树枝较浅，在日本和韩国之间或日本内部的单倍型几乎没有地理分离，这表明日本种群最近才从韩国种群中分离出来。NCA沿海虎甲单倍型的不同地理关联性与距离隔离的限制基因流动被推断出来。在这些系统地理模式的基础上，结合分子时钟的方法，推测了沿海四种虎甲的进化历史，并考虑了这些物种之间的竞争关系。我们还使用进化显著单位的概念，讨论了日本高度地方化的锚叶松种群的保护问题。
To reveal the phylogeographical patterns of four species of coastal tiger beetles in Japan (Lophyridia angulata, Abroscelis anchoralis, Cicindela lewisii and Chaetodera laetescripta), we conducted phylogenetic and nested clade analysis (NCA) using the mitochondrial DNA sequences of two loci (COI and 16S rRNA), with specimens sampled from Japan and neighbouring countries. Abroscelis anchoralis and L. angulata have similar disjunct distributions in Japan. The NCA indicated past fragmentation involving three isolated areas of A. anchoralis. In contrast, local populations of L. angulata in Japan shared the same haplotype, indicating recent vicariance. Co‐occurrence of haplotypes from several divergent clades in Japanese populations of Ch. laetescripta suggested ancient vicariance and subsequent intermixing of local populations. The tree topology of C. lewisii, with shallow branches and little geographical segregation of haplotypes between Japan and Korea or within Japan, suggested that the Japanese population was segregated from the Korean population only recently. Restricted gene flow, with isolation by distance, was inferred for various geographical associations of haplotypes for coastal tiger beetles in the NCA. Based on these phylogeographical patterns, coupled with a molecular clock approach, the evolutionary history of four species of coastal tiger beetles was deduced, with the additional consideration of the competitive relationships among those species. We also discuss the conservation of highly localized A. anchoralis populations in Japan, using the concept of evolutionarily significant units.
