Abstract

Adult female and male of Artogordion ridgeus gen. et sp.n. (Copepoda: Siphonostomatoida) of the family Artotrogidae Brady, 1880 are described from the Gorda Ridge of the North Pacific Ocean. The copepods were found at depths of 2656–2701 m on the margin of a hydrothermal vent field among invertebrates colonizing wood blocks deployed for two years. The new genus differs from other genera of Artotrogidae by a number of primitive features and is close to Myzopontius Giesbrecht, 1895, Sestropontius Giesbrecht, 1899 and Neopontius T. Scott, 1898. It is distinguished from them by segmental fusion pattern of the antennule, the armature of the antennary exopod and the maxillule, and the length and armature of the caudal ramus. This is the second artotrogid to be found in deep water after the discovery of Abyssopontius altus Stock, 1985 in the Indian Ocean.

戈达岭(北太平洋)节肢动物科深海一新属(桡足目:虹口动物)

土竹属(Artogordion ridgeus gen. et sp.)雌雄成虫(桡足目:Siphonostomatoida)属Artotrogidae Brady, 1880年，描述于北太平洋的Gorda Ridge。这些桡足类动物是在海底2656-2701米深的热液喷口边缘，在无脊椎动物中发现的，这些无脊椎动物在木块上定居了两年。该新属与其他翼虫科属有许多不同的原始特征，接近Myzopontius Giesbrecht(1895)、Sestropontius Giesbrecht(1899)和Neopontius T. Scott(1898)。其区别在于触角的节段融合模式、触角外足和上突的电枢以及尾支的长度和电枢。这是继1985年在印度洋发现Abyssopontius altus Stock之后，在深海中发现的第二种类足动物。本文摘自:张建军，张建军，张建军。2018。北太平洋戈尔达海岭(Gorda Ridge) Artotrogidae科深海一新属(桡足目:Siphonostomatoida)黑旋风。Vol.15。3号。p.249 - 266。doi: 10.15298 / invertzool.15.3.04

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.
