Eolouka is an obsolete 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]}
