Order Bubarida

Remarks. The order Bubarida is ill-defined and in need of systematic revision. The order was created in response to genetic support for a clade containing species of Acanthella, Dictyonella, Bubaris, Phakellia and more (Morrow & Cárdenas 2015). This clade was supported by a recent multi-locus phylogeny (Pankey et al. 2022, figure S5); our single-locus phylogenies, which have less resolution but more taxa, are shown in figure 23. Though some species currently placed in the Axinellida are within this green clade, these species are expected to be moved to the Bubarida upon revision, as the type species Axinella polypoides is in a separate clade (Gazave et al. 2010; Pankey et al. 2022; Turner & Pankey 2023).
