Hacrobis, Hacrobia, és un grup proposat de cromalveolats considerat monofilètic, (cryptomonads-haptophytes assemblage)[1] de chromalveolata que no estan inclosos en el SAR supergroup. Hacrobia (deriva d'"ha-" referint-se a Haptophyta, "-cr-" fa referència a cryptomonads, i "-bia" a la vida;[2] CCTH (standing for Cryptophyta, Centrohelida, Telonemia and Haptophyta);[3] i "Eukaryomonadae".[4]

A febrer de 2012 no estava clar si aquest grup era realment monofilètic o no.[3] Two 2012 studies produced opposite results.[5][3]

Membres

[modifica]

En el passat els heterokonta, haptophyta i cryptomonada de vegades s'havien agrupat junts dins chromista.[6]
