Corycidia (alternatively spelt Corycida) is a clade of amoeboid protists within the eukaryotic supergroup Amoebozoa.

It was discovered in 2017 through a phylogenomic study by Senghuo Kang and coauthors, published in the journal Molecular Biology and Evolution.

[2] As of 2019, it is accepted by the International Society of Protistologists as part of the modern cladistic classification of eukaryotes, although under the alternative spelling Corycida.

[1][2] Echinamoebida Arcellinida Euamoebida Leptomyxida Trichosida Microcoryciidae Evosea Discosea A total of 7 genera are included within Corycidia, traditionally organized into two families: Trichosphaeriidae (one genus Trichosphaerium), under the monotypic order Trichosida, and Microcoryciidae (six genera), previously assigned to the order Arcellinida.

[1] The position of the genera Penardochlamys, Microcorycia, Zonomyxa and Parmulina, listed as part of the family Microcoryciidae,[4] is not clear.
