A taxonomic study of deep-sea polychaetes collected at a depth of 2,805 m off the northern coast of California revealed a scaleworm of the family Sigalionidae with an attached parasitic copepod. The copepod represents an undescribed genus of the family Herpyllobiidae, comprising mesoparasitic copepods chiefly recorded from polychaetes of the family Polynoidae. Blakerius gen. nov. diverges from the other herpyllobiid genera by its possession of 1) a chalice-shaped ectosoma with several protuberances along the posterior margin and a long cylindrical shaft with a hyaline coating and integumental sculpturing, a short stalk with a small, anteriorly placed sclerotized ring, 2) a relatively large, discoid-shaped endosoma with digitiform process, and 3) attached male copepodids with 3-segmented antennules, containing limbless sac-like males. The new genus is compared with other herpyllobiids. This discovery increases the number of known herpyllobiid genera to six and is the first record of a herpyllobiid parasitizing a sigalionid polychaete.urn: lsid: zoobank.org:pub:5E31FEED-D3EB-460E-AEA4-02A9D3A778D6.
对加利福尼亚州北部海岸 2805 米深处采集的深海多毛类动物进行的分类研究揭示了一种带有寄生桡足类的沙蚕科环节动物。这种桡足类代表了 Herpyllobiidae 科中一个未被描述的属，主要记录于 Polynoidae 科的多毛类动物身上。Blakerius gen. nov. 与其他 Herpyllobiidae 属的区别在于：1）具有杯状外骨骼，后缘有几个突起，长圆柱形轴有透明涂层和表皮雕刻，短柄有一个小的、位于前部的硬化环；2）相对较大的、盘状的内骨骼，具有指状突起；3）附着的雄性桡足类幼体具有 3 节触角，包含无肢囊状雄性。新属与其他 Herpyllobiidae 进行了比较。这一发现将已知的 Herpyllobiidae 属增加到六个，并且是寄生在 Sigalionidae 环节动物上的 Herpyllobiidae 的首次记录。
