Haptista is a proposed group of protists made up of centrohelids and haptophytes.

Phylogenomic studies indicate that Haptista, together with Ancoracysta twista, forms a sister clade to the SAR+Telonemia supergroup, but it may also be sister to the Cryptista (+Archaeplastida).

[1][2][3][4] It is thus one of the earliest diverging Diaphoretickes.

Based on studies done by Cavalier-Smith, Chao & Lewis 2015[5] and Ruggiero et al.
