'''Diphylleidae''' (also '''Collodictyonidae''') is a group of aquatic, unicellular eukaryotic organisms with two to four terminal flagella. They feed by phagocytosis, ingesting other unicellular organisms like algae and bacteria. It is the sister group of Sulcomonadidae.<ref>{{Cite journal |last=Cavalier-Smith |first=Thomas |date=2013-05-01 |title=Early evolution of eukaryote feeding modes, cell structural diversity, and classification of the protozoan phyla Loukozoa, Sulcozoa, and Choanozoa |url=https://www.sciencedirect.com/science/article/pii/S0932473912000508 |journal=European Journal of Protistology |volume=49 |issue=2 |pages=115–178 |doi=10.1016/j.ejop.2012.06.001 |issn=0932-4739|url-access=subscription }}</ref>
Recent molecular analyses place collodictyonids (e.g. ''Collodictyon'') in a clade also containing Rigifilida and Mantamonadidae. This clade has been named CRuMs and is sister to Amorphea.<ref>{{Cite journal|last1=Lax|first1=Gordon|last2=Eglit|first2=Yana|last3=Eme|first3=Laura|last4=Bertrand|first4=Erin M.|last5=Roger|first5=Andrew J.|last6=Simpson|first6=Alastair G.
