Abstract

We report the first record of the pallenopsid pycnogonid species Bathypallenopsis californica (Schimkewitsch, 1893) from the northwestern Pacific. Based on one male specimen collected from 1987-2007 m depth off the southeastern coast of Hokkaido, Japan, we redescribe the species and present its cytochrome c oxidase subunit I (COI) sequence for use in future DNA barcoding. We found a cystidean-stage crinoid on the leg-1 femur of the sea spider, representing the first record of a cystidean found on a sea spider. BLAST searches for COI and 28S sequences revealed that the crinoid was Florometra asperrima (Clark, 1907).

西北太平洋深海蜘蛛加利福尼亚深叶蜘蛛（节肢纲：海蜘蛛）首次记录，附海百合纲注释。

本文报道了西北太平洋地区首次记录到的pallenopsid pycnogonid物种Bathypallenopsis californica （Schimkewitsch, 1893）。基于1987-2007年在日本北海道东南海岸采集的一个雄性标本，我们重新描述了该物种，并提出了其细胞色素c氧化酶亚基I （COI）序列，用于未来的DNA条形码。我们在海蜘蛛的腿-1股骨上发现了一个囊状体阶段的海百合，这是在海蜘蛛身上发现的第一个囊状体记录。BLAST搜索COI和28S序列，发现该海红属Florometra asperrima （Clark, 1907）。

期刊介绍： Zoological Science is published by the Zoological Society of Japan and devoted to publication of original articles, reviews and editorials that cover the broad field of zoology. The journal was founded in 1984 as a result of the consolidation of Zoological Magazine (1888–1983) and Annotationes Zoologicae Japonenses (1897–1983), the former official journals of the Zoological Society of Japan. Each annual volume consists of six regular issues, one every two months.
