The Kryptotrochozoa (incl. Entoprocta + Ectoprocta) are a proposed Lophotrochozoa clade. It consists of the Nemertea and Lophophorata.{{cite journal|vauthors=Luo YJ, Kanda M, Koyanagi R, Hisata K, Akiyama T, Sakamoto H, Sakamoto T, Satoh N|date=January 2018|title=Nemertean and phoronid genomes reveal lophotrochozoan evolution and the origin of bilaterian heads|journal=Nature Ecology & Evolution|volume=2|issue=1|pages=141–151|doi=10.1038/s41559-017-0389-y|pmid=29203924|doi-access=free}} It is controversial.{{cite journal|vauthors=Nesnidal MP, Helmkampf M, Meyer A, Witek A, Bruchhaus I, Ebersberger I, Hankeln T, Lieb B, Struck TH, Hausdorf B|date=November 2013|title=New phylogenomic data support the monophyly of Lophophorata and an Ectoproct-Phoronid clade and indicate that Polyzoa and Kryptrochozoa are caused by systematic bias|journal=BMC Evolutionary Biology|volume=13|issue=1|pages=253|doi=10.1186/1471-2148-13-253|pmc=4225663|pmid=24238092 |doi-access=free }}
