利用线粒体细胞色素氧化酶亚基I（COI）基因和细胞核28S rRNA基因序列，研究了日本真褐天牛属（鞘翅目：褐天牛科）的系统发育关系。 根据分子系统学和形态学特征，提出了褐角真脊脂鲤的种属地位。系统发育分析恢复单系的先前提出的pellucidus种组与4个日本种，而一个单一的日本种的granicollis组被包括在血统的ramicornis组与5个日本种。根据化石记录和基于COI基因的分子钟构建的系统发育树，估算了该物种的分化时间。日本物种的分歧被推断发生在上新世。
The phylogenetic relationships among the Japanese members of the genus Eubrianax (Coleoptera: Psephenidae) were examined using the mitochondrial cytochrome oxidase subunit I (COI) gene and nuclear 28S rRNA gene sequences. Based on the molecular phylogeny as well as morphological features, the species status of Eubrianax brunneicornis Nakane, 1952 was proposed. The phylogenetic analyses recovered monophyly of the previously proposed pellucidus species group with four Japanese species, whereas a single Japanese species of the granicollis group was included in the lineage of the ramicornis group with five Japanese species. The divergence times of the species were estimated by dating the phylogenetic tree against the fossil record and a molecular clock based on the COI gene. The divergence of the Japanese species was inferred to have occurred during the Pliocene epoch.
