We report an entoproct epibiotic on the surface of a sea spider (Pycnogonida). The pycnogonid was identified as Nymphon sp. (Nymphonidae). The entoproct was colonial, with three zooids, and was identified both morphologically and by a molecular phylogeny as Barentsia sp. (Barentsiidae). The largest zooid had eight tentacles and was about 0.7 mm long, smaller than for most colonial entoproct species. We determined partial sequences for the 18S rRNA and 28S rRNA genes from the entoproct. In an 18S-based maximum likelihood tree (1507 characters), the entoproct was the sister taxon to Barentsia gracilis.
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.
