"eolouka" scientific classification domain: eukaryota clade: diphoda clade: discoba phylum: eoloukacavalier-smith, 2013 stat. nov. groups included jakobea tsukubea cladistically included but traditionally excluded taxa discicristata euglenozoa percolozoa history of classification in 1999 cavalier-smith proposed a new paraphyletic phylum of flagellates called loukozoa, containing only the jakobids. in 2013 it was modified to contain three subphyla: 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.
