Tribe Cheiloprionini .

— This tribe is the basal member of the subfamily Pomacentrinae . It contains four genera ( Cheiloprion, Chrysiptera sensu stricto, Dischistodus, and Pomachromis) and lineages of ‘‘ Chrysiptera ’’ not most closely related to C. cyanea . Most studies with sufficient taxon sampling have found a clade consistent with that composition in the same part of the tree (Cooper et al., 2009; Cowman and Bellwood, 2011; Hofmann et al., 2012; Litsios et al., 2012a, 2012b; Frédérich et al., 2013; Rabosky et al., 2013, 2018; Lobato et al., 2014; DiBattista et al., 2016; Gaboriau et al., 2018; Delrieu-Trottin et al., 2019). In addition to the coral specialist, Cheiloprion, the rest of the tribe shows a wide variety of diets, ranging from herbivores (including algal farmers) to omnivores (including detritivores) and planktivores (Pratchett et al., 2016). Most of the diversity in this group comes from species historically classified as Chrysiptera, which is broadly polyphyletic.
