| description | This biogeographical analysis examines the historical, geological, climatic and ecological processes that have influenced the formation of the dry tropical forests (DTF) of Mesoamerica and Colombia, areas that are the setting for multiple biogeographical stories that in this case are illustrated by the patterns and evolutionary processes of Canthonini. In this study we test the hypothesis that the Canthonini fauna of dry tropical forests has a South American affinity. To this end, we compare extant species from a tract of dry tropical forest in Mexico, a second enclave in Costa Rica, four from the Caribbean region of Colombia and finally one from the north of Tolima in the Upper Magdalena River Valley, Colombia. The geomorphological characteristics of the enclaves of DTF are also compared, as are the geographical distribution and taxonomic affinities of each of the species found in these dry tropical forests. The biogeographical, historical and geological aspects of the enclaves were evaluated using a Parsimony Analysis of Endemicity (PAE), with two tropical rain forests as the outgroup: Leticia (Amazonas, Colombia) and Los Tuxtlas (Veracruz, Mexico).This study reveals the origin and distribution of Neotropical dry forests in the Pleistocene, and the establishment of its dry conditions during the Holocene. It also reveals apparent similarities among the Canthonini of the dry tropical forests of Mexico, Costa Rica and Colombia, with three geographical distribution patterns that correspond to different degrees of expansion towards the north and the diversification of evolutionary lines, and even species of South American origin.The comparison of the cladogram generated for species of Canthonini with that of the geological events that have occurred in the study regions indicates that the distribution of Canthonini in dry tropical forests began during the Pliocene with the re-establishment of the Panamanian connection, with no evidence of previous geomorphological events having any influence. On the other hand, there are few species shared with the tropical rain forests used as the outgroup for the cladograms. |

Este análisis biogeográfico examina los procesos históricos, geológicos, climáticos y ecológicos que han influido en la formación de los bosques tropicales secos (DTF) de Mesoamérica y Colombia, bosques que son sitios de múltiples historias biogeográficas como la que ilustran los Canthonini. Sometemos a prueba la hipótesis de que la fauna de Canthonini de los bosques tropicales secos tiene una afinidad sudamericana. Para este propósito comparamos las especies que se encuentran en un enclave de bosque tropical seco en México, en un segundo enclave en Costa Rica, en cuatro de la región Caribe de Colombia y finalmente uno más en el norte de Tolima en el valle superior del río Magdalena, Colombia. Las características geomorfológicas de los enclaves son también comparadas, así como la distribución geográfica y las afinidades taxonómicas de cada una de las especies de Canthonini que se encuentran en estos bosques tropicales secos. Los aspectos de historia biogeográfica, geológica y ecológica de los enclaves son evaluados usando un Análisis de Parsimonia de Endemicidad (PAE), utilizando como grupo externo dos lugares de selva siempre verde: Leticia (Amazonas, Colombia) y Los Tuxtlas (Veracruz, México). Este estudio pone de manifiesto que el origen y distribución de los bosques tropicales secos de la región ocurre durante el Pleistoceno, con una acentuación de las características de sequía durante el Holoceno. También revela similitudes entre los Canthonini de los bosques tropicales secos de México, Costa Rica y Colombia, con tres patrones de distribución que corresponden a diferentes grados de expansión hacia el norte y a la diversificación de líneas evolutivas, incluso a la presencia de especies sudamericanas.La comparación entre el cladograma generado por las especies de Canthonini y el de eventos geológicos, indica que la distribución de los primeros en los bosques tropicales secos comienza en el Plioceno con el restablecimiento de la conexión panameña, sin evidencias de que eventos geomorfológicos previos hayan ejercido influencias. Por otra parte, hay muy pocas especies compartidas con las selvas siempre verdes usadas como grupo externo en los cladogramas.
