摘要

我们描述了从日本尾鹫海岸外330米深的沉木中采集到的Pericelis nivea sp.这是第一次记录到来自深海区的 Pericelis。nivea sp. nov.的特点是没有眼点。我们提供了线粒体细胞色素 c 氧化酶亚单位 I 基因的部分序列，作为该新物种的 DNA 条形码。基于核18S和28S核糖体DNA序列的系统进化分析表明，P. nivea sp.nov.以较高的支持率嵌套在Pericelis支系中；然而，P. nivea sp.nov.与其他Pericelis物种之间的关系并不清楚。

Description of a new species of Pericelis (Polycladida, Diposthidae) from sunken wood in the bathyal zone in Japan

We describe Pericelis nivea sp. nov. from sunken wood collected 330 m deep, off the coast of Owase, Japan. This is the first record of Pericelis from the bathyal zone. Unlike other congeners, P. nivea sp. nov. is characterized by the absence of eyespots. We provide a partial sequence of the mitochondrial cytochrome c oxidase subunit I gene as a DNA barcode for the new species. Phylogenetic analyses based on concatenated sequences of nuclear 18S and 28S ribosomal DNA showed that P. nivea sp. nov. was nested in the clade of Pericelis with high support; however, the relationship between P. nivea sp. nov. and other Pericelis species was unclear.

期刊介绍： JMBA is an international journal, publishing original research on all aspects of marine biology. It includes pioneering work taking place today on major issues concerning marine organisms and their environment. Subjects covered include: ecological surveys and population studies of marine communities; physiology and experimental biology; taxonomy, morphology and life history of marine animals and plants; and chemical and physical oceanographic work. Included with 2010 online subscriptions: Marine Biodiversity Records.
