collodictyonidae collodictyonidae collodictyonidae (also diphylleidae) 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. the most remarkable fact of this clade is its uncertain position in the tree of life. collodictyonidae collodictyon sp. scientific classification domain: eukaryota clade: opimoda clade: podiata clade: crums family: collodictyonidaebrugerolle et al. 2002 genera collodictyon carter 1865 diphylleia massart 1920 non michaux 1803 synonyms diphylleidae cavalier-smith 1993 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. phylogeny scotokaryota metamonada cavalier-smith 1987 emend. cavalier-smith 2003 opimoda ancyromonadida cavalier-smith 1998 emend. atkins 2000 malawimonadea cavalier-smith 2003 podiata amorphea amoebozoa lühe 1913 emend. cavalier-smith 1998 obazoa breviatea cavalier-smith 2004 apusomonadida karpov & mylnikov 1989 opisthokonta crums mantamonadida cavalier-smith 2004 rigifilida karpov & mylnikov 1989 diphylleida cavalier-smith 1993 taxonomy class diphyllatea cavalier-smith 2003 order diphylleida cavalier-smith 1993 family sulcomonadidae cavalier-smith 2012 genus sulcomonas brugerolle 2006 species s. lacustris brugerolle 2006 family diphylleidae cavalier-smith 1993 genus diphylleia massart 1920 non michaux 1803 species d. rotans massart 1920 genus collodictyon carter 1865 species c. hongkongense skvortzov 1968 species c. indicum iyengar 1981 species c. oxycareni franchini 1922 species c. sparsevacuolatum skuja 1956 species c. triciliatum carter 1865
