The US Virgin Islands (USVI) include St. John and St. Thomas on the Puerto Rican Platform (PRP) and St. Croix, isolated by 2000 m deep water 45 km south of that platform. Previous inventories of the marine fishes of these islands include a comprehensive 2014 checklist of the fishes of St. Croix and a list of the fishes of the PRP produced in 2000. The latter list noted the locations of many records of the plateau's fishes, allowing the construction of a combined inventory for St. John and St. Thomas. Those two islands are treated here as a single faunal unit because they are only 3.5 km apart on a shared shallow shelf with various islets and reefs in between. Here we provide updated information on those two USVI (St. Croix and St. John-Thomas) marine fish faunas. The additions to the St. Croix and St. John-Thomas inventories presented here are based on a combination of information from the two sources indicated above, more recent publications dealing with those faunas, a review of location records on various online sources of biogeographic data, and voucher photographs taken of fishes in the field by authors of this paper and other citizen scientists. This assessment increased the known fauna of St. Croix by 7.5% to 585 species. The inventory for St. John-Thomas increased by 39.9% from 401 species on the 2000 PRP list to 561 with the inclusion of records from other sources. On-site mtDNA (COI) barcodes are available for approximately one-third of the species of the St. John-Thomas fauna, but for only one species collected at St. Croix. A set of underwater photographs of 372 species (34 of them representing the sole record of a species) from St. John-Thomas and of 11 shallow-water species added to the St. Croix fauna is included. These represent occurrence vouchers and also are intended to facilitate future work that builds on the present compendium.
美属维尔京群岛（USVI）包括位于波多黎各陆架（PRP）上的圣约翰岛和圣托马斯岛，以及位于该陆架以南45公里处、被2000米深海水隔开的圣克罗伊岛。此前对这些岛屿海洋鱼类的清查包括2014年一份全面的圣克罗伊岛鱼类清单，以及2000年编制的一份波多黎各陆架鱼类清单。后一份清单记录了该高原许多鱼类记录的位置，从而得以构建圣约翰岛和圣托马斯岛的综合清单。这两个岛屿在这里被视为一个单一的动物区系单元，因为它们在一个共享的浅海大陆架上相距仅3.5公里，中间有各种小岛和珊瑚礁。在此，我们提供了关于这两个美属维尔京群岛（圣克罗伊岛以及圣约翰岛 - 托马斯岛）海洋鱼类区系的最新信息。此处呈现的圣克罗伊岛和圣约翰岛 - 托马斯岛清单的新增内容，是基于上述两个来源的信息、近期关于这些动物区系的出版物、对各种在线生物地理数据来源的位置记录的审查，以及本文作者和其他公民科学家在野外拍摄的鱼类凭证照片。此次评估使圣克罗伊岛已知的动物区系增加了7.5%，达到585种。圣约翰岛 - 托马斯岛的清单从2000年波多黎各陆架清单中的401种增加了39.9%，纳入其他来源记录后达到561种。圣约翰岛 - 托马斯岛动物区系约三分之一的物种有现场线粒体DNA（COI）条形码，但圣克罗伊岛仅有一种采集到的物种有该条形码。还包括一组来自圣约翰岛 - 托马斯岛的372种鱼类的水下照片（其中34种代表一个物种的唯一记录），以及添加到圣克罗伊岛动物区系的11种浅水物种的照片。这些照片既是出现凭证，也旨在促进基于本汇编开展的未来工作。
