摘要

新头足类腹足目动物是从热喷口到有机瀑布等以化学合成为基础的生态系统的特有动物,但人们对它们的多样性和进化史仍然知之甚少。在西南太平洋,弧后盆地和火山弧上的深海热液喷口分布在三个地理位置隐蔽的区域:马努斯盆地周围的西部区域、北斐济和劳盆地周围的东部区域,以及中间的伍德拉克盆地,那里的活动喷口直到最近才在2019年的R/V L'Atalante CHUBACARC考察中得到证实。虽然已经发现了新头足类蜗牛的多个品系,但通常仅限于这三个地区中的一个,其中一些品系一直没有名称。在此,我们使用综合分类法描述了其中的三个物种:来自伍德拉克盆地的新头椎蜗牛 Symmetromphalus mithril sp.nov.,来自东部地区的盾形蜗牛 Symmetriapelta becki sp.结合贝壳的雕刻和放射状特征,可以从形态学上将这些新物种与其描述的同属物种区分开来。根据线粒体细胞色素 c 氧化酶亚单位 I 基因的 570 bp 重建的分子系统发生证实了这三个新物种在各自属和新头足目超科中的位置。这些新腹足类动物的发现,尤其是来自云雀盆地的新腹足类动物的发现,除了突出了云雀动物群落的独特性之外,还对云雀作为一个扩散中心的历史作用提供了见解和影响。

Integrative taxonomy of new neomphaloidean gastropods from deep-sea hot vents of the southwestern Pacific
Neomphaloidean gastropods are endemic to chemosynthesis-based ecosystems ranging from hot vents to organic falls, and their diversity and evolutionary history remain poorly understood. In the southwestern Pacific, deep-sea hydrothermal vents on back-arc basins and volcanic arcs are found in three geographically secluded regions: a western region around Manus Basin, an eastern region around North Fiji and Lau Basins, and the intermediate Woodlark Basin where active venting was confirmed only recently, on the 2019 R/V L’Atalante CHUBACARC expedition. Although various lineages of neomphaloidean snails have been detected, typically restricted to one of the three regions, some of these have remained without names. Here, we use integrative taxonomy to describe three of these species: the neomphalid Symmetromphalus mithril sp. nov. from Woodlark Basin and the peltospirids Symmetriapelta becki sp. nov. from the eastern region and Symmetriapelta radiata sp. nov. from Woodlark Basin. A combination of shell sculpture and radular characters allow the morphological separation of these new species from their described congeners. A molecular phylogeny reconstructed from 570 bp of the mitochondrial cytochrome c oxidase subunit I gene confirmed the placement of the three new species in their respective genera and the superfamily Neomphaloidea. The finding of these new gastropods, particularly the ones from the Woodlark Basin, provides insights and implications on the historical role of Woodlark as a dispersing centre, in addition to highlighting the uniqueness of the Woodlark faunal community.

期刊介绍: The Zoological Journal of the Linnean Society publishes papers on systematic and evolutionary zoology and comparative, functional and other studies where relevant to these areas. Studies of extinct as well as living animals are included. Reviews are also published; these may be invited by the Editorial Board, but uninvited reviews may also be considered. The Zoological Journal also has a wide circulation amongst zoologists and although narrowly specialized papers are not excluded, potential authors should bear that readership in mind.
