• Monneoncideres, a new genus of Onciderini Thomson, 1860 (Coleoptera: Cerambycidae: Lamiinae) is described and illustrated. Six new species of Onciderini are also described and illustrated: Hesycha tavakiliani from Brazil; Lesbates milleri from Venezuela; Monneoncideres cristata from Ecuador and Peru; Neodillonia waltersi from Ecuador; Tibiosioma martinsi from Ecuador; and Trestonia wappesi from Panama. Keys to the known species of Lesbates Dillon and Dillon, 1945 and Tibiosioma Martins and Galilleo, 1990 are provided. The genus Ophthalmocydrus Aurivillius, 1925 (Onciderini) is transferred to Pteropliini (Lamiinae); and Xylomimus Bates, 1865 (Apomecynini) is transferred to Onciderini. The following new synonymies are proposed: Kuauna Martins and Galileo, 2009 = Opthalmocydrus Aurivillius, 1925; Kuauna schmidi Martins and Galileo, 2009 = Ophthalmocydrus semiorbifer Aurivillius, 1925; Paraplerodia Martins and Galileo, 2010 = Tibiosioma Martins and Galileo, 2007; Paraplerodia acarinata Martins and Galileo, 2010 = Tibiosioma maculosa Martins and Galileo, 2007; and Ischiomaeocles Franz, 1954 = Lochmaeocles Bates, 1880. The following new combination is proposed: Lochmaeocles salvadorensis (Franz, 1954), transferred from Ischiomaeocles. The following 37 new country records are reported: Alexera barii (Jekel, 1861) (Bolivia, Ecuador); Bacuris sexvittatus (Bates, 1865) (Panama); Cacostola brasiliensis Thomson, 1868 (Argentina); Cherentes niveilateris (Thomson, 1868) (French Guiana); Cicatrodea monima Dillon and Dillon, 1946 (Ecuador); Clavidesmus metallicus (Thomson, 1868) (Ecuador, Peru); Cydros leucurus Pascoe, 1866 (Brazil); Ecthoea quadricornis (Olivier, 1792) (Ecuador); Eudesmus grisescens Audinet-Serville, 1835 (Ecuador, Trinidad and Tobago, Venezuela); Euthima variegata (Aurivillius, 1921) (Ecuador); Hesychotypa heraldica (Bates, 1872) (Belize, Guatemala); Hesychotypa punctata Martins, 1979 (Peru); Lochmaeocles basalis Dillon and Dillon, 1946 (Ecuador, Trinidad and Tobago); Lochmaeocles zonatus Dillon and Dillon, 1946 (Venezuela); Lydipta conspersa (Aurivillius, 1922) (Peru); Neocherentes dilloniorum Tippmann, 1960 (Brazil); Neolampedusa obliquator (Fabricius, 1801) (Ecuador); Peritrox perbra Dillon and Dillon, 1945 (Ecuador); Priscatoides tatila Dillon and Dillon, 1945 (Bolivia); Strioderes peruanus Giorgi, 2001 (Brazil); Trachysomus apipunga Martins and Galileo, 2008 (Peru); Trachysomus camelus Buquet, 1852 (Venezuela); Trachysomus peregrinus Thomson, 1858 (Ecuador); Trachysomus thomsoni Aurivillius, 1923 (Venezuela); Trestoncideres laterialba Martins and Galileo, 1990 (Brazil); Trestonia exotica Galileo and Martins, 1990 (Ecuador); Trestonia fulgurata Buquet, 1859 (Grenada, Trinidad and Tobago); Tritania dilloni Chalumeau, 1990 (Venezuela); Tulcus paganus (Pascoe, 1859) (Ecuador); Xylomimus baculus Bates, 1865 (French Guiana).
