Group of protists
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 .
