A new species of the genus Liropus (Crustacea, Amphipoda, Caprellidae) is described based on specimens collected from a small cave of Santa Catalina Island, California. The new species, Liropus minusculus, can be distinguished from all its congeners mainly by the presence of anterolateral projections on pereonites 2, 3, and 4 (males), pereopod 5 one-articulate (although with a second article incompletely tabicated), basis of gnathopod 2 very elongate (males), and abdomen with two pairs of one-articulate appendages (males), one of them rudimentary. Up-to-date morphological comparisons among the world Liropus species are provided, together with an illustrated key to species. This is the first record of Liropus from the north-east Pacific.
基于从加利福尼亚州圣卡塔利娜岛一个小洞穴中采集的标本，描述了Liropus属（甲壳纲，端足目，麦秆虫科）的一个新物种。新物种Liropus minusculus与所有同属物种的主要区别在于，第2、3和4胸节（雄性）有前侧突，第5步足单关节（尽管第二节未完全分化），第2颚足基部非常细长（雄性），以及腹部有两对单关节附肢（雄性），其中一对退化。提供了世界上Liropus属物种最新的形态学比较，以及物种图解检索表。这是Liropus属在东北太平洋的首次记录。
