Resumen
The placement of the southern border of the Neotropical region, called the Subtropical Line, is a long-lasting point of discussion. Its most debatable section runs around the Pampean province, where an isolated mountain system called Ventania has Andean connections surrounded by Neotropical biota. To answer where to place the Subtropical Line, a thorough revision of the biogeography of Ventania is needed. Thus, we characterized Ventania as an area of endemism and conducted a similitude analysis to compare it with surrounding systems using stenoic taxa. Then we compiled the disjunct distributions in Ventania and the phylogenetic information of its endemic taxa to know with which other areas it is related. We also compared the biogeographic differences with Tandilia, the nearest mountain system. We found that Ventania is a small but well-defined area of endemism mostly related to the Andean and South American Transition Zone (SATZ) provinces. Relatedness with the Pampean province is less than had been thought. We suggest that Ventania is a SATZ sky island province, and the smallest continental province of the world. The Subtropical Line should therefore be placed in the southern border of the Pampean province, with Ventania as a SATZ island inside the Neotropical region
