摘要。具有跨大陆分布的收获属是罕见的，但为进化和生物地理学研究提供了非常有趣的模型。然而，在试图了解这些分布之前，对焦点分类群有一个良好的分类基础是至关重要的。Nuncia Loman, 1902 （Triaenonychidae）是新西兰和南美洲有记录的最不一致的收割机属之一，但其α分类还有待改进，主要是在雄性生殖器形态的详细表征方面。对小姑属植物的分类和系统修订仍然是一个重要而有趣的问题，而对小姑属植物的重新描述（Simon, 1899）是对该属植物进行分类修订的必要起点。本文通过对1902年滇北梭子鱼（Nuncia sperata Loman）（滇北梭子鱼的模式种）和1899年滇北梭子鱼（Triaenonyx obesus Simon）（滇北梭子鱼的高级同义种）全型的重新研究，对滇北梭子鱼进行了重新描述和说明。我们也确认了这两个物种的同义关系。
Abstract. Harvestmen genera with transcontinental distributions are rare but represent very interesting models for evolutionary and biogeographical studies. However, before attempting to understand such distributions, it is crucial to have a good taxonomic foundation of the focal taxa. One of the most disjunct harvestmen genera is Nuncia Loman, 1902 (Triaenonychidae), which has been recorded from New Zealand and South America, but the alpha taxonomy is in need of improvement, mainly with respect to the detailed characterization of male genitalic morphology. The taxonomic and systematic revision of Nuncia remains an important and intriguing issue, and the redescription of Nuncia obesa (Simon, 1899) is a necessary starting point for the taxonomic revision of the genus. Herein we redescribe and illustrate N. obesa based on the reexamination of the syntypes of Nuncia sperata Loman, 1902 (type species of Nuncia) and the holotype of Triaenonyx obesus Simon, 1899 (senior synonym of Nuncia sperata). We also confirm the synonymy of both species.
