  • 🧍 Formerly Proteus vulgaris biogroup 3. — 🧍 O'Hara et al. (2000) propose Proteus hauseri as a nomen revictum [Proteus hauseri (ex Kauffmann 1954) O'Hara et al. 2000, sp. nov., nom. rev.]. However, "Proteus hauseri" Kauffmann 1954, included Proteus mirabilis Hauser 1885 (Approved Lists 1980) and Proteus vulgaris Hauser 1885 (Approved Lists 1980). So, Proteus hauseri O'Hara et al. 2000 and "Proteus hauseri" Kauffmann 1954 are different taxa, and according to Rules 28a and 33c, Proteus hauseri O'Hara et al. 2000 is not a revived name.
