Taxonomic remark Initial scope of Hacrobia defined by Okamoto et al., 2009 as follows: "Katablepharids and cryptophytes are together part of a larger, more inclusive, group [i.e., Hacrobia] that also contains haptophytes, telonemids, centrohelids and perhaps biliphytes". Cavalier-Smith (to 2018) maintains the supposed phylogenetic relationship of cryptomonads and haptophytes as subkingdom Hacrobia in kingdom Chromista, however according to Strassert et al., 2021 and others, while haptophytes are related to the "SAR" group (the core of Cavalier-Smith's Chromista), cryptophytes are not and group more closely with Archaeplastida i.e. land plants, rhodophytes and glaucophytes.
