To map the gracillariid species diversity, we adopted the regionalization of the Neotropical region as proposed by Morrone
(2014), using the corresponding shape file that was provided by Löwenberg-Neto (2014) to plot the data. These authors adopted a restrictivedefinitionofthe Neotropical region, excluding the southernportionoftheAndeanarea and alsonorthernMexico. To conceal this with the database provided by De Prins and De Prins (2016a), who adopted a broader view, these areas were herein included in the analyses, and thus treated in conjunction with the remaining subregions (sensu Cox, 2001). The idea was to have representative subdivisions from a biogeographic perspective, without necessarily taking into account the ranks proposed by Morrone (2014).
