Seamounts are well known for the high biodiversity and endemism of their macrobenthic fauna. Hundreds of squat lobster species from seamount environments have been reported in recent years, but squat lobster fauna on the seamount groups around ocean trenches in the tropical West Pacific are still poorly known. In this paper, we describe 11 new species (two Munida, three Munidopsis, one Sternostylus, one Uroptychodes and four Uroptychus) based on specimens collected during expeditions to seamounts around the Yap Trench and Mariana Trench. Of these species, six belong to the superfamily Chirostyloidea and five belong to Galatheoidea. We also provide DNA barcode data for three genes to support the taxonomic status of these new species. The morphological variations, genetic differentiation and phylogenetic relationships of these species are discussed.

对来自雅浦和马里亚纳海沟周围海山的 11 种新蹲龙虾（甲壳纲：Anomura）的描述，并附有 DNA 条形码和系统发育的注释

海山以其丰富的生物多样性和大型底栖动物的特有性而闻名。近年来报道了数百种来自海山环境的蹲龙虾物种，但热带西太平洋海沟周围海山群的蹲龙虾动物群仍然鲜为人知。在本文中，我们根据在雅浦海沟和马里亚纳海沟周围海山探险期间收集的标本，描述了 11 个新物种（2 个 Munida、3 个 Munidopsis、1 个 Sternostylus、1 个 Uroptychodes 和 4 个 Uroptychus）。在这些物种中，有 6 个属于 Chirostyloidea 超科，5 个属于 Galatheoidea。我们还提供三个基因的 DNA 条形码数据，以支持这些新物种的分类地位。讨论了这些物种的形态变异、遗传分化和系统发育关系。
