The Nearctic is generally interpreted as that part of the Americas north of the Caribbean and north of the USA/Mexican border. However, sub-tropical southern Florida has strong faunal connections with the Caribbean, and parts of northern Mexico share faunal similarities with Southwestern USA. Despite this, there is a remarkable discontinuity in the region of the USA/Mexican border, in that the diverse and worldwide genus Thrips appears to have almost no native species south of this border.
