A new marine tardigrade, Moebjergarctus clarionclippertonensis sp. nov., is described based on specimens collected from a manganese nodule area in the Clarion-Clipperton Fracture Zone of the abyssal North-eastern Pacific. The new species is a member of the bathyal/abyssal subfamily Euclavarctinae Renaud-Mornant, 1983. Within the Euclavarctinae, the genus Moebjergarctus Bussau, 1992, with only one described species, M. manganis Bussau, 1992, is characterised by simple claws, club-shaped and anteriorly bent primary clavae, well-developed spherical secondary clavae and cephalic cirri separated into three parts: short cirrophore, long and annulated scapus, and a short flagellum. Moebjergarctus clarionclippertonensis sp. nov. can be distinguished from M. manganis by the morphology of cephalic cirri which have scapi annulated only in the proximal part and by the presence of a caudodorsal bulge covered by a crescent-shaped cuticular thickening.
基于从东北太平洋深海克拉里昂-克利珀顿断裂带的一个锰结核区域采集的标本，描述了一种新的海洋缓步动物，即克拉里昂-克利珀顿莫氏熊虫（Moebjergarctus clarionclippertonensis sp. nov.）。新物种是1983年深海底栖/深渊亚科真熊虫亚科（Euclavarctinae Renaud-Mornant）的成员。在真熊虫亚科中，莫氏熊虫属（Moebjergarctus Bussau，1992）仅有一种已描述物种，即1992年的锰莫氏熊虫（M. manganis Bussau），其特征为简单的爪、棒状且向前弯曲的初级棒节、发育良好的球形次级棒节以及头部触须分为三部分：短的触须柄、长且具环纹的柄节和短的鞭毛。克拉里昂-克利珀顿莫氏熊虫（Moebjergarctus clarionclippertonensis sp. nov.）可通过头部触须的形态与锰莫氏熊虫区分开来，前者的柄节仅在近端具环纹，且存在一个被新月形角质增厚覆盖的尾背隆起。
