The Clarion-Clipperton Zone (CCZ) occupies a vast swathe of the Pacific with extensive polymetallic nodule deposits. Eastern and central parts host diverse assemblages of xenophyophores (megafaunal agglutinated foraminifera). Here we describe xenophyophores obtained using a Remotely Operated Vehicle from the western CCZ. Eleven distinct forms include two known species, Stannophyllum zonarium Haeckel, 1888 and Aschemonella monile Gooday and Holzmann in Gooday et al., 2017b. Another four are described as new species based on morphological and genetic data. In Abyssalia foliformis gen. nov., sp. nov. and Abyssalia sphaerica sp. nov. the flattened or spherical test comprises a homogeneous framework of sponge spicules. Psammina tenuis sp. nov. has a delicate, thin, plate-like test. Moanammina semicircularis gen. nov., sp. nov. has a stalked, fan-shaped test and is genetically identical to ‘Galatheammina sp. 6’ of Gooday and co-workers from the eastern CCZ. Sequence data revealed a spherical ‘mudball’, which disintegrated and cannot be formally described, to be a novel xenophyophore. Finally, four morphospecies are represented by dead tests: Psammina spp., Reticulammina sp., and an unknown genus with a unique test structure. This collection enhances our knowledge of Pacific xenophyophore diversity and provides the first genetic confirmation of wide geographic ranges for abyssal species.

克拉里昂-克利珀顿区（CCZ）占据了太平洋的广阔地带，拥有大量的多金属结核矿床。东部和中部地区有各种各样的异生植物（巨型真菌有孔虫）。在这里，我们描述了使用遥控车辆从西部CCZ获得的异生植物。11个不同的形式包括两个已知物种，即Stannophyllum zonarium Haeckel，1888和Gooday et al。，2017b中的Monile Aschemonella monile Gooday和Holzmann。根据形态和遗传数据，另四个​​物种被描述为新物种。在阿比萨利亚（Abyssalia）叶形植物中。十一月，sp。十一月 和Abyssalia sphaerica sp。十一月 扁平或球形测试包括海绵针的均匀框架。Psammina细叶SP。十一月 具有细腻，薄板状的测试。Moanammina semicircularis gen。十一月，sp。十一月 具有茎杆状的茎秆测试，并且在遗传上与Galatheammina sp。相同。Gooday和来自东部CCZ的同事们的6'。序列数据显示球形“泥浆”是一种新型的异生植物，其分解后无法正式描述。最后，死测代表了四种形态学物种：沙门氏菌属，网状菌属和一个具有独特测试结构的未知属。该集合增强了我们对太平洋异生植物多样性的了解，并为深渊物种的广泛地理范围提供了第一个遗传学确认。
