Abstract The article provides an overview of the diversity of the genus Munidopsis Whiteaves, 1874 (Crustacea: Decapoda: Anomura: Galatheidea: Munidopsidae) along the Russian Northern Pacific coastline, based on recently collected and museum specimens. Six different species are recorded in the northwestern Pacific Ocean (NW Pacific), including three new species, Munidopsis kurilensis sp. nov., Munidopsis asiatica sp. nov. and Munidopsis piipa sp. nov., described in the Derjugin and the Kuril basins of the Sea of Okhotsk and active Piip submarine volcano in the Bering Sea, respectively. Moreover, Munidopsis cf. subsquamosa Henderson, 1885 is reported at the Sea of Okhotsk for the first time. Two species, Munidopsis petalorhyncha Baba, 2005 and Munidopsis beringana Benedict, 1902, previously known from the area, are re-described in details. The article discusses all known records of the genus Munidopsis from the NW Pacific, comments on their morphology, relationships, distribution and ecology, as well as on the importance of their study. A discussion of zoogeography and the possible pathways that shape contemporary diversity in the NW Pacific is also presented in the article. About half of the collected samples of these deep-sea squat lobsters were taken due to the long-term and very effective Russian–German scientific collaboration in the study of the deep-sea environments.

深海的北方独角兽：1874 年太平洋西北部的 Munidopsis Whiteaves 属的多样性（十足目：Anomura：Munidopsidae），描述了俄罗斯沿岸的三个新物种

摘要 本文根据最近收集的和博物馆标本，概述了 1874 年 Munidopsis Whiteaves 属（甲壳纲：十足目：Anomura：Galatheidea：Munidopsidae）沿俄罗斯北太平洋海岸线的多样性。在西北太平洋（NW Pacific）记录了六个不同的物种，包括三个新物种，Munidopsis kurilensis sp。十一月，Munidopsis asiatica sp。十一月 和 Munidopsis piipa sp。11 月，分别在鄂霍次克海的 Derjugin 和千岛盆地以及白令海的活跃 Piip 海底火山中进行了描述。此外，Munidopsis cf。subsquamosa Henderson, 1885 首次在鄂霍次克海被报道。两个物种，Munidopsis petalorhyncha Baba, 2005 和 Munidopsis beringana Benedict, 1902，以前在该地区已知，现在重新详细描述。文章讨论了西北太平洋 Munidopsis 属的所有已知记录，评论了它们的形态、关系、分布和生态，以及它们研究的重要性。文章还讨论了动物地理学和塑造西北太平洋当代多样性的可能途径。由于俄罗斯和德国在深海环境研究方面的长期和非常有效的科学合作，这些深海蹲龙虾的收集样本中约有一半是采集的。文章还讨论了动物地理学和塑造西北太平洋当代多样性的可能途径。由于俄罗斯和德国在深海环境研究方面的长期和非常有效的科学合作，这些深海蹲龙虾的收集样本中约有一半是采集的。文章还讨论了动物地理学和塑造西北太平洋当代多样性的可能途径。由于俄罗斯和德国在深海环境研究方面的长期和非常有效的科学合作，这些深海蹲龙虾的收集样本中约有一半是采集的。
