Carcinonemertid monostiliferanOvicides paralithodisKajihara and Kuris, 2013 最初被描述为鄂霍次克海、白令海和阿拉斯加湾红王蟹Paralithodes camtschaticus(Tilesius, 1815)的卵捕食者。在本研究中，从日本海的雪蟹Chionoecetes opilio（O. Fabricius，1788）的卵块中获得了几个carcinonemertid标本。从两个癌鱼标本中测定的线粒体细胞色素氧化酶亚基 I 基因 (COI) 的部分序列与 O 正模型的条形码序列相同。 paralithodis，表明该物种的寄主范围至少涵盖了两种十足目物种P. camtschaticus 和 C.奥皮利奥。
The carcinonemertid monostiliferanOvicides paralithodisKajihara and Kuris, 2013 was originally described as an egg predator of the red-king crabParalithodes camtschaticus(Tilesius, 1815) in the Sea of Okhotsk, the Bering Sea, and the Gulf of Alaska. In the present study, several carcinonemertid specimens were obtained from the egg mass of the snow crabChionoecetes opilio(O. Fabricius, 1788) in the Sea of Japan. Partial sequences of the mitochondrial cytochromecoxidase subunit I gene (COI) determined from two specimens of the carcinonemertid were identical with a barcode sequence from the holotype ofO. paralithodis, indicating that the host range of the species covers at least the two decapod species,P. camtschaticusandC. opilio.
