Distributional patterns of the South American Aterpini (Coleoptera: Curculionidae)

The 23 species of South American Aterpini, belonging to the genera Aegorhinus Erichson, Alastoropolus Kuschel, and Micropolus Kuschel, are distributed in four areas of endemism, namely, Central Chile, Maule, the Valdivian forest, and the Magellanic forest. Distributional patterns of these species fo...

These patterns are similar to those found in the Rhytirrhinini, although Aterpini are absent from the Magellanic moorland and the Falkland Islands. Las 23 especies sudamericanas de Aterpini, pertenecientes a los géneros Aegorhinus Erichson, Alastoropolus Kuschel y Micropolus Kuschel, se distribuyen en cuatro áreas de endemismo: Chile Central, Maule, selva Valdiviana y selva Magallánica. Los patrones de distribución de estas especies siguen dos trazos generalizados: uno conecta Chile Central y el Maule, mientras que el otro conecta el Maule, la selva Valdiviana y la selva Magallánica. Debido a sus relaciones conflictivas, se postula que el Maule es un nodo. Se presentan dos cladogramas de áreas alternativos para explicar su naturaleza compleja: uno muestra la secuencia (selva Valdiviana (Maule, Chile Central)), mientras que el segundo muestra la secuencia (selva Magallánica (Maule, selva Valdiviana)). Estos patrones son similares a los hallados en Rhytirrhinini, aunque los Aterpini están ausentes en el páramo Magallánico y las Islas Malvinas.
