Subphyla & classes

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. [2]

Although it has sometimes placed along with Haptista in the group Hacrobia, within the kingdom Chromista, [3] most recent studies have found that Hacrobia is not a clade. [4] 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. [5] [6]
