    Notes:
    • 🧍 Prevotella zoogleoformans (Weinberg et al. 1937) Shah and Collins 1990 emend. Moore et al. 1994 is illegitimate because it is a homotypic synonym of a type species with a genus name that has priority.
    • 🧍 The Subcommittee on the taxonomy of Gram-negative anaerobic rods recommends that Prevotella zoogleoformans (Weinberg et al. 1937) Shah and Collins 1990 be designated Bacteroides zoogleoformans (Weinberg et al. 1937) Cato et al. 1982.
