Track analysis of the Mexican species of Cerambycidae (Insecta, Coleoptera)

Abstract

A track analysis of 221 species belonging to 68 genera of Mexican Cerambycidae was undertaken in order to identify their main distributional patterns. Based on the comparison of the individual tracks, fifteen generalized tracks were obtained: six are placed in the Neotropical region, seven are shared by the Neotropical region and the Mexican Transition Zone, one is situated in the Mexican Transition Zone, and one is shared by the Nearctic region and the Mexican Transition Zone. Eight nodes were found in the intersection of these generalized tracks, five of them located in the Neotropical region and three in the Mexican Transition Zone. Distributional patterns of Mexican Cerambycidae show two basic patterns: one mostly Neotropical, in the Mesoamerican dominion (Mexican Pacific Coast and Mexican Gulf biogeographic provinces) and another in the Mexican Transition Zone (Transmexican Volcanic Belt and Balsas Basin biogeographic provinces).
