Cladistically included but traditionally excluded taxa

Eolouka is a paraphyletic phylum of protists localized in the clade Discoba. It contains two lineages: Jakobea and Tsukubea, the last containing only one genus, Tsukubamonas.[1][2]

History of classification

In 1999 Cavalier-Smith proposed a new paraphyletic phylum of flagellates called Loukozoa, containing only the jakobids.[3] In 2013 it was modified to contain three subphyla:[1]

  • Eolouka, containing the classes Jakobea and Tsukubea.
  • Metamonada, containing the infraphyla Trichozoa and Anaeromonada.
  • Neolouka, containing the only class Malawimonadea.

However, in later years these three groups were raised to the rank of phylum.[4][2]
