Discoba or JEH clade

Euglenozoa and Heterolobosea (Percolozoa) or Eozoa (as named by Cavalier-Smith) appear to be particularly close relatives, and are united by the presence of discoid cristae within the mitochondria (Superphylum Discicristata). A close relationship has been shown between Discicristata and Jakobida, the latter having tubular cristae like most other protists, and hence were united under the taxon name Discoba, which was proposed for this supposedly monophyletic group.
