Status Mitochondrial DNA data (Biermann et al. 2003: fig. 2) show that Allocentrotus fragilis is nested within a monophyletic clade formed by Hemicentrotus pulcherrimus, Strongylocentrotus intermedius, S. purpuratus, S. pallidus, and S. droebachiensis. Recognition of Allocentrotus would thus render Strongylocentrotus paraphylletic. Pearse & Mooi (2007: p. 917) thus consider Allocentrotus as junior synonym of Strongylocentrotus. [details]
