The Commission has ruled that the generic name Trigonostomum Burmeister, 1844 for a scarabeid beetle be suppressed, and the incorrect subsequent spelling Trigonostomus Brenske, 1893 is deemed available. The Commission has also ruled the entire generic name Trigonostomus Brenske, 1893 should be adopted as the stem, so that the correct spelling of the chafer subtribe name will become trigonostomusina Ohaus, 1912 to remove homonymy with the flatworm family-group name trigonostomidae Graff, 1905. This conserves the widespread usage of the generic name Trigonostomum Schmidt, 1852 for a group of marine flatworms.
