Molorchus minor minor (Linnaeus) (Coleoptera, Cerambycidae) is recorded for the first time in Brazil (Bahia). It was originally described from Europe and is currently widely distributed in that continent and Asia.

Five new species and one new genus of Cerambycidae are described from Maranhão: Mirador ayrii gen. nov., sp. nov.; Stizocera ignea sp. nov.; Engyum vicinum sp. nov.; Thoracibidion rubripenne sp. nov.; Polyrhaphis ju sp. nov.
