The Neotropics is generally considered as that part of the Americas south of Florida and south of the USA/Mexican border. However, southern Florida is susceptible to invasion by species from the tropics, and the thrips fauna of the drier northern parts of Mesoamerica is substantially different from the wet tropical areas further south. Similarly, the thrips fauna of southern South America appears to be different from that of the tropical areas.
