Revision of higher taxonomic classification of eukaryote—As for classification in Adl et al. (2019)—

Abstract

A new revision of the higher taxonomic classification of eukaryotes was published in 2019 in the journal of the International Society of Protistologists, Journal of Eukaryotic Microbiology. In the seven years since the last revision made in 2012, the large-scale multigene phylogenetic analyses in the background of the recent advancement of sequencing technology have revealed the affiliation of many “orphan” lineages and taxa. The major changes in this revision are the following four points: i) Excavata is not adopted to be a clade, ii) CRuMs as an assembly of Collodictyonida, Rigifilida, and Mantamonas is adopted to be a clade as the relatives of Amorphea, iii) Haptista consisted of Haptophyta and Centrohelida is adopted as a new clade, and iv) Crypista is also adopted as a new clade.
