Abstract The post‐Miocene climatic history of arid environments in South America has been identified as a key driver dispersal and diversification, particularly among plant groups such Cactaceae. Despite their iconic status, many cactus genera remain poorly understood, comprehensive taxonomic systematic revisions using morphological genomic data are complex time‐consuming, resulting few studies to date. Here we present study the genus Austrocactus , currently with 10 accepted species native southern Andean Argentina parts Chile. is based on an extensive sampling covering both overall range diversity genus. We used ddRADseq approach phylogenetic relationships incorporating 44 individuals representing all morphospecies, widespread represented by several samples geographical spectrum. were analyzed maximum likelihood multispecies coalescence‐based models, well principal component analyses, providing well‐supported robust evolutionary framework. Based data, propose revised classification genus, total 17 species, 5 which described new. also provide updated infrageneric two subgenera three sections, circumscription including descriptions respective key. Finally, suggest specific research directions focused integrating ecological modeling complement our work enhance biogeographic understanding these species.
