Tropical America is currently experiencing the establishment of a new apex insect predator, the Paleotropical dragonfly Hemianax ephippiger (Odonata: Aeshnidae). H. ephippiger is migratory and is suggested to have colonised the eastern Neotropics by chance Trans-Atlantic displacement. We report the discovery of H. ephippiger at three new locations in the Caribbean, the islands of Bonaire, Isla de Coche (Venezuela), and Martinique, and we review its reported distribution across the Neotropics. We discuss the establishment of H. ephippiger as a new apex insect predator in the Americas, both in terms of ecological implications and the possible provision of ecosystem services. We also provide an additional new species record for Bonaire, Pantala hymenaea (Odonata: Libellulidae).

加勒比地区古热带迁徙 Hemianax ephippiger 的新记录及其在新热带地区的地位回顾

热带美洲目前正在建立一种新的顶端昆虫捕食者，即古热带蜻蜓 Hemianax ephippiger（蜻蜓目：Aeshnidae）。H. ephippiger 是迁徙的，并被认为是偶然跨大西洋迁移到新热带东部的殖民地。我们报告了在加勒比海三个新地点、博内尔岛、科什岛（委内瑞拉）和马提尼克岛发现 H. ephippiger，并回顾了其在新热带地区的报告分布。我们在生态影响和可能提供的生态系统服务方面讨论了 H. ephippiger 作为美洲新的顶级昆虫捕食者的建立。我们还为博内尔岛、Pantala hymenaea (Odonata: Libellulidae) 提供了一个额外的新物种记录。
