The aeolid species Facelina bostoniensis (Couthouy, 1838) was originally described from Massachusetts and was later reported from the Eastern Atlantic Ocean and the Mediterranean Sea. So far, no molecular systematic study of its amphiatlantic status has been carried out. Phylogenetic analyses (maximum likelihood and Bayesian) of DNA sequence data for the mitochondrial cytochrome c oxidase subunit I and 16S rRNA genes confirm the amphiatlantic status of F. bostoniensis. My findings show that this species is restricted to the Atlantic realm and that the species recorded from the Mediterranean is not F. bostoniensis but F. vicina (Bergh, 1882). It is hypothesized that previous records of F. bostoniensis from the Mediterranean Sea were actually misidentifications of F. vicina.

调查波斯纳面（Facelina bostoniensis）的两栖状态（Couthouy，1838年）（Nudibranchia：Aeolidida）

最早来自马萨诸塞州的风神物种Facelina bostoniensis（Couthouy，1838），后来从东大西洋和地中海报道。迄今为止，尚未对其两栖状态进行分子系统研究。线粒体细胞色素C氧化酶亚基I和16S rRNA基因的DNA序列数据的系统发育分析（最大似然和贝叶斯分析）证实了F. bostoniensis的两栖状态。我的发现表明，该物种仅限于大西洋地区，从地中海记录的物种不是F. bostoniensis，而是F. vicina（Bergh，1882）。假设以前的记录来自地中海的波士顿F.菌实际上是维氏菌F.的误认。
