ABSTRACT
The Neotropical region corresponds to the tropics of the New World, from Mexico to Argentina. The early history of its biogeographic regionalization began with Sclater (1858), Wallace (1876), and Engler (1879). During the nineteenth and twentieth centuries, several authors have provided maps recognizing subregions, dominions, and provinces in the Neotropical region or areas within it (Morrone, 2010b).
