Four genera of the trigonopoid Platynotina are revised: Amblychirus Koch, Melanopterus Mulsant et Rey, Selinopodus Koch and Trigonopus Mulsant et Rey. Six new species to science are described: Trigonopus sigillatus, T. similis, T. danielssoni, T. signus, T. cochraneae and Amblychirus pseudobrevior. A new synonymy is proposed: Melanopterus porcus (Mulsant et Rey, 1853) (= Trigonopus exaratus Mulsant et Rey, 1853). Lectotypes are designated. The genus Melanopterus is reinterpreted. Keys for species determination are provided.
