Synopsis and cladistics of the American Aterpini (Coleoptera: Curculionidae, Cyclominae)
Abstract The American members of the tribe Aterpini are restricted to the Central Chilean and Subantarctic biogeographic subregions of southern South America. They include the genera Alastoropolus Kuschel, with one species (A. strumosus), and Aegorhinus Erichson ( = Micropolus Kuschel, syn. n.), wit...
