Classes

Loukozoa (From Greek loukos: groove[1]) is a paraphyletic taxon used in some classifications of excavate protists.[2][3]

The largest group within Loukozoa is the "Jakobids". Loukozoa, however, also includes Malawimonas. Although Jakobids and Malawimonas look rather similar, they are not specifically related to one another within Excavata, and Loukozoa is a paraphyletic group. Furthermore, molecular phylogenetic evidence suggests strongly that Jakobids are instead most closely related to Heterolobosea and Euglenozoa.[4]
