Unikont

Unikonts are members of the Unikonta, a taxonomic group proposed by Thomas Cavalier-Smith.
The International Society of Protistologists the recognised body for taxonomy of protozoa recommended in 2012 that the term Unikont be changed to Amorphea.〔Adl SM, Simpson AG, Lane CE, Lukeš J, Bass D, Bowser SS, Brown MW, Burki F, Dunthorn M, Hampl V, Heiss A, Hoppenrath M, Lara E, Le Gall L, Lynn DH, McManus H, Mitchell EA, Mozley-Stanridge SE, Parfrey LW, Pawlowski J, Rueckert S, Shadwick RS, Schoch CL, Smirnov A, Spiegel FW (2012) The revised classification of eukaryotes. J Eukaryot Microbiol 59(5):429-93. doi: 10.1111/j.1550-7408.2012.00644.x.〕
It includes amoebozoa, opisthokonts, and possibly Apusozoa.
==Taxonomic revisions within this group==

Cavalier-Smith has proposed two new phyla: Sulcozoa which consists of the subphyla Apusozoa (Apusomonadida, Breviatea) and Varisulca which includes the subphyla Diphyllatea, Discocelida, Mantamonadida, Planomonadida and Rigifilida.〔Cavalier-Smith T (2013) Early evolution of eukaryote feeding modes, cell structural diversity, and classification of the protozoan phyla Loukozoa, Sulcozoa, and Choanozoa. Eur J Protistol 49(2):115-78. doi: 10.1016/j.ejop.2012.06.001.〕 The validity of this proposed taxonomy has yet to ruled upon by the Society of Protistologists.
Further work by Cavalier-Smith has shown that Sulcozoa is paraphyetic.〔Cavalier-Smith T, Chao EE, Snell EA, Berney C, Fiore-Donno AM, Lewis R (2014) Multigene eukaryote phylogeny reveals the likely protozoan ancestors of opisthokonts (animals, fungi, choanozoans) and Amoebozoa. Mol Phylogenet Evol 81:71-85. doi: 10.1016/j.ympev.2014.08.012 〕 Apusozoa also appears to be paraphyetic. Varisulca has been redefined to include planomonads, Mantamonas and Collodictyon. A new taxon has been created - Glissodiscea - for the planomonads and Mantamonas. Again the validity of this revised taxonomy awaits approval by the Society.
Amoebozoa seems to be monophyetic〔Cavalier-Smith T, Fiore-Donno AM, Chao E, Kudryavtsev A, Berney C, Snell EA, Lewis R (2015) Multigene phylogeny resolves deep branching of Amoebozoa. Mol Phylogenet Evol 83:293-304. doi: 10.1016/j.ympev.2014.08.011 〕 with two major branches: Conosa and Lobosa. Conosa is divided into the aerobic infraphylum Semiconosia (Mycetozoa and Variosea) and secondarily anaerobic Archamoebae. Lobosa consists entirely of non-flagellated lobose amoebae and has been divided into into two classes: Discosea which have flattened cells and Tubulinea with predominantly tube-shaped pseudopodia.
