Abstract

Several specimens of benthic siphonophorae of the family Rhodaliidae were recorded during dives of the ROV “Comanche 18” at depths of 1711–1914 m in vicinity of submarine Piyp Volcano located north off Commander Islands in NW Pacific. The specimens were not collected, but recorded in details on video files and photographic images underwater in their natural habitat. Unlike other siphonophores the members of the family Rhodaliidae are benthic. Almost all species of this family are poorly known, and most are known from very few specimens, some of which were collected more than 100 years ago and newer recorded again. Till now rhodaliids were not known from NW Pacific at depths greater than 1000 m. In the present paper we describe a brief history of the family, the morphology of the recorded here specimens basing on photo and video data, and provide a list of all described species of the family with short comments on each. It is shown that the generic name Tridensa Hissmann, 2005 is not available and cannot be used. How to cite this article: Sanamyan K.E., Sanamyan N.P., Galkin S.V., Ivin V.V. 2018.

西北太平洋Piyp海底火山附近深海底栖虹吸虫记录(虹吸虫科:水蛭科:蔷薇科)

在西北太平洋指挥官群岛以北的Piyp火山附近，潜水机器人“科曼奇18”在1711-1914米的深度潜水时，记录了几个底栖动物管水母科的标本。这些标本并没有被采集，而是在水下自然栖息地的视频文件和照片中详细记录下来。与其他管水母不同，rhodalidae家族的成员是底栖动物。这个科的几乎所有物种都不为人所知，而且大多数都是从很少的标本中知道的，其中一些是在100多年前收集的，最近又记录了一次。到目前为止，还没有在西北太平洋深度超过1000米的地方发现过菱形鱼。在本文中，我们描述了该科的简史，在照片和视频资料的基础上记录了标本的形态，并提供了该科所有已描述物种的清单，并对每个物种进行了简短的评论。结果表明，通用名称Tridensa Hissmann, 2005是不可用的，不能使用。本文摘自:Sanamyan k.e.， Sanamyan n.p.， Galkin s.v.， Ivin V.V. 2018。西北太平洋Piyp火山附近深海底栖虹吸虫记录(虹吸虫科:水蛭科:蔷薇科)// Invert.Zool。Vol.15。4号。p.323 - 332。doi: 10.15298 / invertzool.15.4.01

期刊介绍： Scientific peer-reviewed journal INVERTEBRATE ZOOLOGY publishes original papers, reviews and brief communications on morphology, anatomy, embryology, taxonomy, phylogeny, and ecology of any group of invertebrates from protistans to lower chordates. INVERTEBRATE ZOOLOGY accepts manuscripts in English or Russian and publishes them in printed and electronic versions. The Russian translations of English titles, abstracts and figure captions of the papers written by non-Russian authors can be provided by the editors. Invertebrate Zoology invites authors to publish extended monographic manuscripts after usual reviewing procedure. The monographic manuscripts can include up to 400 thousand letters and be prepared in English or in Russian. Accepted monographic manuscripts will have priority to be published in the nearest issue of the journal.
