Hamaticherus Dejean, 1821 (Coleoptera: Cerambycidae: Cerambycinae) is considered a junior synonym of Cerambyx Linnaeus, 1758. Hamaticherus sensu Audinet-Serville, 1834 is considered a posterior usage of Hamaticherus Dejean, 1821, and an unavailable name. Plocaederus is considered as a new genus, and not a replacement name, proposed by Dejean (1835) to allocate the species included in Hamaticherus sensu Audinet-Serville, 1834. Therefore, a new genus, Hamaederus Santos-Silva, Garcia and Botero, is herein pro­posed to include the species currently allocated in Plocaederus Dejean, 1835, creating 15 new combinations, and additionally, a new species from French Guiana, Hamaederus allofasciatus Santos-Silva, Garcia and Botero, is described. Furthermore, Plocaederus barauna Martins and Monné, 2002 and Plocaederus confu­sus Martins and Monné, 2002 are proposed as new junior synonyms of Hamaederus yucatecus (Chemsak and Noguera, 1997), and Hamaticherus bellator Audinet-Serville, 1834 is transferred to Plocaederus Dejean, 1835, new combination. New geographical records are provided for Hamaederus fraterculus (Martins), H. glaberrimus (Martins), H. rusticus (Gounelle), and H. yucatecus (Chemsak and Noguera). Hamaederus fas­ciatus is formally excluded from the fauna of French Guiana. A key to American genera of Cerambycina (Cerambycini) is provided.
