Collodictyon triciliatum
Collodictyon is a basal genus of single-celled eukaryotes not closely related to any heretofore known kingdom of that domain.
Collodictyon
Three species are currently recognised in this genus. The type species is Collodictyon triciliatum. A second species—Collodictyon sparsevacuolatum—named by Skuja is also recognised; this species is found in freshwater in the United States and Europe. A third species Collodictyon sphaericum has been described but its description is in doubt. A fourth species—Collodictyon hongkongense—has been described by Skvortzow but this description is considered inadequate and this species is regarded as being of dubious validity.
Along with the genus Diphylleia, this organism appears to be only distantly related to the other eukaryotes. They share some morphological features with the species currently placed within the Excavata. However this latter clade is considered to be polyphyletic and in need of resolution (reorganisation into different groups). For this reason inclusion of this genus within the excavates may not assist in understanding its phylogenetic position.
Brugerolle has proposed a family, Collodictyonidae for this genus and Diphylleia.
