Scientific classification
Domain:	Eukaryota

Clade:	Haptista; Cavalier-Smith 2015
Subgroups
	Haptophyta; Centroplasthelida;

Haptista is a group of protists made up of centrohelids and haptophytes. Phylogenomic studies indicate that Haptista is likely closely related to the TSAR supergroup.^[2]^[3]^[4] It is thus one of the earliest diverging Diaphoretickes.

Jamy et al. discovered the "leptophytes", a potential sister group to haptophytes detected through environmental DNA of plastids.^[5]
