Resumen:
The Andes mountain range extends over 8500 km along the Pacific coast of South America. Its medium altitude is 3500 m, reaching more than 6000 m at different latitudes. The uplift of the Andes splits arid habitats creating very diverse ecosystems on both sides. The distribution of the Pimeliinae (Coleoptera: Tenebrionidae) south of parallel 15º South is analysed, where the Andean mountain range separates xeric habitats both eastward and westward. The genera of Pimeliinae show four distribution patterns: endemic taxa east of the Andes, endemic taxa west of the Andes, taxa widely distributed on both sides of the Andes, and taxa inhabiting high altitudes in the Andes. Known phylogenies of genera and species of Pimeliinae are examined in terms of the Andean mountain uplift creating a vicariant event. A biogeographical track exhibited by certain genera of Pimeliinae connecting central Chile and southern Argentina is examined.
