The long-legged flies (Dolichopodidae) of the island of Montserrat in the Lesser Antilles have been surveyed and include 63 species in 27 genera. The following eleven new species are described and illustrated: Amblypsilopus marskeaesp. nov., Medetera ivieisp. nov., Medetera montserratensissp. nov., Systenus ladonnaesp. nov., Thrypticus mediofuscussp. nov., Chrysotus antillensissp. nov., Chrysotus callichromoidessp. nov., Chrysotus interfronssp. nov., Chrysotus montserratensissp. nov., Diaphorus robinsonisp. nov., and Sympycnus montserratensissp. nov. Six species have only been found on Montserrat (ca. 10% endemicity). Keys are provided to the genera and species on Montserrat, their known distribution summarized, and additional new island records provided for many species. Asyndetus wirthi Robinson is synonymized with A. interruptus (Loew) and Achradocera apicalis (Aldrich) is removed from synonymy with A. barbata (Loew). Diaphorus flavipes Aldrich is transferred to Chrysotus as a new combination. A new replacement name, Chrysotus milvadunom. nov., is provided for the Nearctic Chrysotus parvulus Van Duzee. Lectotypes are designated for Achradocera apicalis (Aldrich) and Asyndetus fratellus Aldrich. The fauna of Montserrat is summarized and compared with that of Dominica. Collecting methods are compared and threats to the dolichopodid fauna of Montserrat discussed.

西印度群岛蒙特塞拉特的 Dolichopodidae（双翅目）

对小安的列斯群岛蒙特塞拉特岛的长腿苍蝇（Dolichopodidae）进行了调查，包括 27 属 63 种。描述和说明了以下 11 个新物种：Amblypsilopus marskeaesp。十一月，Medetera ivieisp。十一月，Medetera montserratensissp。十一月，Systenus ladonnaesp。十一月， Thrypticus mediofuscussp。十一月，Chrysotus antillensissp。十一月，Chrysotus callichromoidessp。十一月，Chrysotus interfronssp。十一月，Chrysotus montserratensissp。11 月，Diaphorus robinsonisp。11 月和 Sympycnus montserratensissp。十一月 仅在蒙特塞拉特 (Montserrat) 发现了 6 种物种（大约 10% 的地方性）。为蒙特塞拉特岛的属和种提供了关键信息，总结了它们的已知分布，并为许多物种提供了额外的新岛屿记录。Asyndetus wirthi Robinson 是 A. 从与 A. barbata (Loew) 的同义词中删除了 interruptus (Loew) 和 Achradocera apicalis (Aldrich)。Diaphorus flavipes Aldrich 作为新组合转移到 Chrysotus。一个新的替代名称，Chrysotus milvadunom。11 月，提供给 Nearctic Chrysotus parvulus Van Duzee。选型被指定为 Achradocera apicalis (Aldrich) 和 Asyndetus fratellus Aldrich。总结蒙特塞拉特的动物群并与多米尼加的动物群进行比较。对收集方法进行了比较，并讨论了对蒙特塞拉特岛长足动物群的威胁。选型被指定为 Achradocera apicalis (Aldrich) 和 Asyndetus fratellus Aldrich。总结蒙特塞拉特的动物群并与多米尼加的动物群进行比较。对收集方法进行了比较，并讨论了对蒙特塞拉特岛长足动物群的威胁。选型被指定为 Achradocera apicalis (Aldrich) 和 Asyndetus fratellus Aldrich。总结蒙特塞拉特的动物群并与多米尼加的动物群进行比较。对收集方法进行了比较，并讨论了对蒙特塞拉特岛长足动物群的威胁。
