Anasca was a bryozoan suborder under class Cheilostomida defined by the lack of an ascus in each zooid. It is no longer an accepted taxonomic grouping as it is considered a polyphyletic and/or paraphyletic grouping.^[1] The group is now subdivided into the suborders Inovicellata, Scrupariina, Malacostega, and Flustrina.^[1]
