Rigifila (from Latin rigidus 'stiff' and filum 'thread') is a genus of free-living single-celled eukaryotes, or protists, containing the sole species Rigifila ramosa (from Latin ramosus 'branched'). It is classified within the monotypic family Rigifilidae. Along with Micronucleariidae, it is a member of Rigifilida, an order of basal eukaryotes within the CRuMs clade. It differs from Micronuclearia by having two proteic layers surrounding their cytoplasm instead of a single one, and having more irregular mitochondrial cristae, among other morphological differences.
