  • 🧍 On the Approved Lists 1980, the effective publication for the genus Rhodococcus is a paper by Goodfellow and Alderson 1977. In this paper, the nomenclatural name Rhodococcus is assigned to the neuter gender! However, in accordance with Rule 65(2) a generic name which is modern coupound from two Greek words take the gender of the last component of the compound word. In Greek, kokkos is in the masculine gender, and the genus name Rhodococcus should be assigned to the masculine gender. — Rhodococcus Zopf 1891 may violate Principle 2 and Rule 51b (4) because of the presence ofthe algal genus Rhodococcus Hansgirg 1884.
