description | Seven Deltochilina species (Anomiopus cirulito, Canthon triangularis, C. lituratus, C. edmondsi, C. morsei, C. angustatus and C. lucreciae) were used as biogeographic indicators, to exemplify the influence of South American fauna in Mexican tropical diversity, seeking to explain why Mexico, south of the Isthmus of Tehuantepec, is increasingly Neotropical. The time scale used is from the end of the Pleistocene to the present time and three levels of information were considered: 1) Penetration with minimal presence, 2) Penetration with marginal populations and 3) Penetration with established populations. Examples of foreign invaders that have successfully established in livestock areas, without displacing any native species, are provided in this study. The natural phenomena that have conditioned the current distribution of the selected indicators correspond to geological and macroclimatic processes, which influenced the composition and movements of horobiota at the continental level. The tendency of Deltochilini from Central and South America to invade Mexico has been very intense, using the Panamanian Bridge or even the inter-Caribbean bridge to disperse, advancing with the jungle and, their number exceeds the incipient species of recent penetration, of any other border of Mexico. |

Se utilizaron como indicadores biogeográficos siete especies de Deltochilina (Anomiopus cirulito, Canthon triangularis, C. lituratus, C. edmondsi, C. morsei, C. angustatus y C. lucreciae), para ejemplificar la influencia de la fauna sudamericana en la diversidad tropical mexicana, buscando explicar por qué México, al sur del Istmo de Tehuantepec, es cada vez más Neotropical. La escala temporal empleada es del fin del Pleistoceno a la época actual y se consideraron tres niveles de información: 1) Penetración con presencia mínima, 2) Penetración con poblaciones marginales y 3) Penetración con poblaciones establecidas. Se ofrecen ejemplos de invasores foráneos que han tenido éxito en lugares ganaderos, sin desplazar a ninguna especie autóctona. Los fenómenos naturales que han condicionado la distribución actual de las especies indicadoras seleccionadas se corresponden con procesos geológicos y macroclimáticos, que influyeron en la composición y los movimientos de las horobiotas a nivel continental. La tendencia de Deltochilini de Centro y Sudamérica por invadir México ha sido muy intensa, empleando el Puente Panameño o incluso el puente inter-Caribe para dispersarse, avanzando con las selvas y, su número supera a las especies incipientes de penetración reciente, de cualquier otro borde de México.
