Abstract: Phylogenetic diversity measures rank areas for biodiversity conservation priorities based on information encoded in phylogenies (cladograms). The goal of these ranks is to consider as many factors possible that provide additional taxic information, such taxa richness, distributional patterns, area endemicity, and complementarity between areas. At present there are phylogenetic including node‐based, genetic‐distance, feature‐based measures. We devised a modified node‐based index we call “taxonomic endemicity standardized weight,” which considers not only the taxonomic distinctness inhabit given but their well. Once weight identifies highest priority, can be used identify second so on. this priority southern South America, compared results our rankings other indexes. Our identified Santiago district, Central Chile province, conservation, followed by Maule, Malvinas, districts Subantarctic province. Malvinas exhibits greater relative than Maule does, however, ranked priority. Indexes measure evolutionary component allow one will ensure preservation potential phylogenetically rare taxa. propose sensitive well allows from diverse combined (i.e., different cladograms). use maximum quantity minimal number protected
