First Record of the Deep-Sea Sea Spider Bathypallenopsis californica (Arthropoda: Pycnogonida) from the Northwestern Pacific, with a Note on an Attached Crinoid
We report the first record of the pallenopsid pycnogonid species <i>Bathypallenopsis californica</i> (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 <i>c</i> 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 <i>Florometra asperrima</i> (Clark, 1907).
