The eukaryotic system in the third update of the interface “Eukaryotic supergroups: Taxonomy/Biotechnology interface”: Formal procedures for rank changes

The problem of coordinating the ranks of higher eukaryotic taxa was specifically considered by us in the monograph and a recent article. However, we omitted most of the formal descriptions of the proposed taxa in the new rank. The purpose of this article is a formal description of a number of taxa established by us in the monograph “Nomenclature and rank correlation of higher taxa of eukaryotes and subsequent interface updates”. Here we formally described such taxa as Eocorticata regn. nov., Tsaralia regn. nov., Apusomonadea intraregn. nov., Breviatea intraregn. nov., Eochromista superphyl. nov., Zoosporia superphyl. nov., Eurhodophyta div. nov., Proteorhodophyta div. nov., Anaeramoebea phyl. et cl. nov., Calkinsea phyl. nov., Meteora phyl. nov., Syssomonadea phyl. nov., Chlorodendrophytina subdiv. nov., Chloropicophytina subdiv. nov., Dikaryomycotina subdiv. nov., Pedinophytina subdiv. nov., Picocystophytina subdiv. nov., Sanchytriomycotina subdiv. nov., Agaricomycia supercl. nov., Calcarisporiellomycia supercl. nov., Ceratiomyxomycia supercl. nov., Chytridiomycia supercl. nov., Entomophthoromycia supercl. nov., Entorrhizomycia supercl. nov., Kickxellomycia supercl. nov., Mortierellomycia supercl. nov., Mucoromycia supercl. nov., Myxogasteromycia supercl. nov., Monoblepharomycia supercl. nov., Neocallimastigomycia supercl. nov., Saccharomycia supercl. nov., Acytosteliomycetes cl. nov., Liceomycetes cl. nov., Microheliellida cl. nov., Paratrimastigidea cl. nov., Protosporangiomycetes cl. nov., Pycnococcophyceae cl. nov. The main trends of further improvement of the rank structure of the eukaryote tree we see in 1) some multiplication of the supregroups described for the few taxa now located among the Amoebozoans and TSAR, as well as many environmental sequences; 2) further rationalization of the Fungi and Metazoa system using intercalary taxonomic categories (including additional and not prescribed in both nomenclatural codes ones), and 3) further automatization of the ranking procedure and solving the problem of rank estimating for distant “orphan” taxa.
