cryptista cryptista cryptista is a clade of alga-like eukaryotes. it is most likely related to archaeplastida which includes plants and many algae, within the larger group diaphoretickes. cryptista rhodomonas salina, a cryptophyte scientific classification kingdom: chromista subkingdom: hacrobia phylum: cryptistaadl et al., 2018 subphyla & classes palpitia palpitea endohelia endohelea rollomonadia leucocrypta cryptomonada goniomonadea cryptophyceae although it has sometimes placed along with haptista in the group hacrobia, within the kingdom chromista, most recent studies have found that hacrobia is not a clade. for example, in 2016, a broad phylogenomic study found that cryptists fall within the group archaeplastida, while haptophytes are closely related to the sar supergroup. taxonomy based on studies done by cavalier-smith, chao & lewis 2015 corbihelia phylum microheliellida tedersoo 2017 class endohelea cavalier-smith 2012 clade cryptista s.s. phylum palpitophyta tedersoo 2017 class palpitea cavalier-smith 2012 clade rollomonadia cavalier-smith 2013 stat. nov. phylum kathablepharidophyta okamoto & inouye 2005 class leucocryptea cavalier-smith 2004 phylum cryptophyta pascher 1913 em. adl et al. 2012 (cryptomonada cavalier-smith 2004 sta. n.] class goniomonadea cavalier-smith 1993 class cryptophyceae fritsch 1937
