摘要

腹足纲是腹足纲中一种完全寄生的甲壳类动物。在皇帝海山链中发现了一种新的副胸足类动物，即皇帝海山链中的帝王金颊龙。三名女性被发现在永久囊肿分离从家庭棘藻科（Malacalcyonacea）的未确定的八珊瑚。利用光镜和扫描电镜对该新种进行了描述，并对其CO1基因序列进行了分析，讨论了其与其他近缘无柄属的分类亲缘关系。比较了Gorgonolaureus、Cardomanica、Isidascus和thalassomailtis的宿主特异性、营养生态学和宿主-寄生虫相互作用，为这些甲壳类动物的生物学研究提供了新的见解。综述了八珊瑚侵染属的分布、深度和寄主分类，揭示了八珊瑚侵染属寄主分类的多样性，以及八珊瑚侵染属的广泛地理分布和垂直分布范围。新物种代表了该属最北端和最深的记录。

The distribution and host utilization of octocoral infesting Ascothoracida (Crustacea, Thecostraca), including the discovery of a new species of Gorgonolaureus from the Emperor sea Mount Chain

Ascothoracida is a small group of exclusively parasitic crustaceans in the class Thecostraca. A new ascothoracidan, Gorgonolaureus imperator sp. nov., was collected from the Emperor Seamount Chain. Three females were found in permanent cysts detached from an undetermined octocoral of the family Acanthogorgiidae (Malacalcyonacea). We provide a description of the new species based on light and scanning electron microscopy together with its CO1 gene sequence and discuss taxonomic affinities of Gorgonolaureus and other closely related sessile genera. Host specificity, trophic ecology and host-parasite interactions of Gorgonolaureus, Cardomanica, Isidascus and Thalassomembracis are compared, providing new insights into the biology of these crustaceans. Previous records of all these octocoral infesting genera with their localities, depths and host taxonomy are summarized, showing the diversity of host taxa, and the wide geographical and vertical ranges of the parasites. The new species represents the northernmost and deepest record for the genus.

期刊介绍： Deep-Sea Research Part II: Topical Studies in Oceanography publishes topical issues from the many international and interdisciplinary projects which are undertaken in oceanography. Besides these special issues from projects, the journal publishes collections of papers presented at conferences. The special issues regularly have electronic annexes of non-text material (numerical data, images, images, video, etc.) which are published with the special issues in ScienceDirect. Deep-Sea Research Part II was split off as a separate journal devoted to topical issues in 1993. Its companion journal Deep-Sea Research Part I: Oceanographic Research Papers, publishes the regular research papers in this area.
