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. Sphagoeme Aurivillius, 1893 is proposed as a new synonym of Limernaea Thomson, 1878, and Sphagoeme nigrotibialis Martins, 1973 is proposed as a new synonym of Limernaea picta Thomson, 1878. A total of 102 known species are recorded for the state of Maranhão for the first time: two Prioninae, 69 Cerambycinae and 31 Lamiinae. Six species are reported for the first time from Brazil. With these new records, and the five new species described, the total number of species recorded from the state of Maranhão increased from 367 to 474.
