The genus Gomphus in tropical and subtropical zones of Mexico

Gomphus calakmulensis, G. albidocarneus and G. pleurobrunnescens are proposed and described as new species from the Mexican states of Campeche and Chiapas, while G. pallidus, previously recorded only in the eastern U.S. and Japan, has now been found in various parts of Mexico for the first time. This work describes the species, illustrates their key features, discusses their distribution, as well as their similarities and differences, and provides an identification key for all of them. All of the specimens studied here come from tropical or subtropical ecosystems.
