What is "halvaria"

Halvaria is a grouping that includes Alveolata and Heterokonta (Stramenopiles).

Analyses in 2007 and 2008 agree that the Stramenopiles and the Alveolata are related, forming a reduced chromalveolate clade. They group together with the Rhizaria (originally one of the six major eukaryote groups) to form a clade dubbed the SAR supergroup.
