Cryptodifflugiidae is a family of arcellinid testate amoebae.{{cite journal|title=Phylogenomics and Morphological Reconstruction of Arcellinida Testate Amoebae Highlight Diversity of Microbial Eukaryotes in the Neoproterozoic|vauthors=Lahr D, Kosakyan A, Lara E, Mitchell E, Morais L, Porfirio-Sousa AL, Ribeiro GM, Tice AK, Pánek T, Kang S, Brown MW|date=2019|doi=10.1016/j.cub.2019.01.078|volume=29|issue=6|pages=991–1001|journal=Current Biology|pmid=30827918|doi-access=free|hdl=10261/240246|hdl-access=free}}
Description
Members of this family are conopodous (with conical pseudopods) amoebae with the body in a clear, usually firm, vase-shaped test, and conical pseudopods for locomotion that extend separately from the opening of the test.{{cite journal|vauthors=Jahn TL, Bovee EC, Griffith DL|date=1974|title=Taxonomy and Evolution of the Sarcodina: A Reclassification|journal=Taxon|volume=23|issue=4|pages=483–496|doi=10.2307/1218771|jstor=1218771 }}
