Note: According to Willems and Collins 1995, Hallella seregens Moore and Moore 1994 is a member of the genus ¤ Prevotella Shah and Collins 1990. However, Willems and Collins do not make a formal proposal to rename Hallella seregens.
Reference: WILLEMS (A.) and COLLINS (M.D.): 16S rRNA gene similarities indicate that Hallella seregens (Moore and Moore) and Mitsuokella dentalis (Haapasalo et al.) are genealogically highly related and are members of the genus Prevotella: emended description of the genus Prevotella (Shah and Collins) and description of Prevotella dentalis comb. nov.
