Endohelea is a proposed clade of eukaryotes that are related to Archaeplastida and the SAR supergroup.[2][3] They used to be considered heliozoans, but phylogenetically they belong to a group of microorganisms known as Cryptista.[1]

Classification

Based on studies done by Cavalier-Smith, Chao & Lewis in 2015, the class contained two orders: Microhelida and Heliomonadida.[4][5] However, according to a study by Cavalier-Smith, published in 2022, the order Heliomonadida is actually part of Cercozoa, and only one species of heliomonad, Tetrahelia pterbica, has been kept in Endohelea as its own order Axomonadida.[1]
