摘要

一种不寻常的多毛目动物Ctenophoricola属的新种被描述为Ctenophoricola tzetlini sp. nov.。这个新种与该属的两个有效物种的身体比例和不同之处在于：具有发育良好的角膜的外部眼睛，类似于自由生活的Alciopini的角膜，身体前部的针状毛羽，具有长肛门cirri的大臀肌，以及分散在身体后部的明显的纤毛束。讨论了新物种与加利福尼亚湾未描述的Ctenophoricola sp.的相似性。我们假设Ctenophoricola属由两个谱系组成，一个是专门作为体外寄生虫的，另一个是更接近自由生活的Alciopini的姐妹群。

A new species of an unusual polychaete genus Ctenophoricola (Phyllodocida, Phyllodocidae, Alciopini) from the Indian Ocean.

A new species belonging to an unusual polychaete genus Ctenophoricola is described as Ctenophoricola tzetlini sp. nov.. The new species differs from the two valid species of the genus in body proportions and in having: external eyes with well-developed cornea resembling those in free-living Alciopini, acicular chaetae in the anterior body region, a large pygidium with long anal cirri, and distinct bundles of cilia scattered over the posterior body region. The new species' similarity to an undescribed Ctenophoricola sp. from the Gulf of California is discussed. We hypothesize that the genus Ctenophoricola consists of two lineages, one strongly specialized as ectoparasites and the sister group closer to free-living Alciopini.

期刊介绍： Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
