Abstract:

The purpose of this application, under Articles 23.4 and 23.9.3 of the Code, is to conserve the widespread usage of the generic name Trigonostomum Schmidt, 1852 for a group of marine flatworms (family TRIGONOSTOMIDAE) and, under Articles 55 and 29 of the Code, to remove the homonymy between the chafer subtribe name TRIGONOSTOMINA Ohaus, 1912 (type genus Trigonostomum Burmeister, 1844; family SCARABAEIDAE) and the flatworm family name TRIGONOSTOMIDAE Graff, 1905 (type genus Trigonostomum Schmidt, 1852). The flatworm genus-group name Trigonostomum Schmidt, 1852 is threatened by the chafer name Trigonostomum Burmeister, 1844. It is proposed that Trigonostomum Burmeister, 1844 be suppressed, the incorrect subsequent spelling Trigonostomus Brenske, 1893 be deemed available as a substitute name for Trigonostomum Burmeister, 1844, and that the entire genus name 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 Graff’s flatworm family name. Trigonostomum setigerum Schmidt, 1852 is herein designated as the type species of Hyporhynchus Graff, 1882 to make this genus-group name an objective junior synonym of Trigonostomum Schmidt, 1852 and HYPORHYNCHINAE Graff, 1882 an objective senior synonym of TRIGONOSTOMIDAE Graff, 1905. According to Article 23.9.2 of the Code it is herein declared that TRIGONOSTOMIDAE is the valid name and has
precedence over HYPORHYNCHINAE.
