SAR is a highly diverse clade of eukaryotes, often considered a supergroup, that includes stramenopiles (heterokonts), alveolates, and rhizarians. It is a node-based taxon (under the Sar name), including all descendants of the three groups' last common ancestor, and comprises most of the now-rejected Chromalveolata. Their sister group might be telonemids, with which they would make up the TSAR (sometimes called T-SAR) clade, but this grouping has been challenged. Harosa is used synonymously with TSAR by Cavalier-Smith in 2022.
