Discussion about several taxonomic acts involving various genus-groups in Buprestidae from the recent Catalogue of Palaearctic Coleoptera, Volume 3 (2006) is given. That catalogue's considerations of the species composition in the following genus-groups are discussed: Amorphosoma Laporte, 1835 and Vanroonia Obenberger 1923; the structure and composition of the Buprestis Linnaeus, 1758 genus-group; and the Meliboeus Deyrolle, 1864 genus-group including Bourgoinia Obenberger, 1926, Lakhonia Descarpentries & Villiers, 1967, Meliacanthus Théry, 1942, Meliboeoides Théry, 1942, Melixes Schaefer, 1950, Nalanda Théry, 1904 and Tonkinula Obenberger 1923, genera vs. subgenera vs. synonyms. Comments about the gender of Trachys Fabricius, 1801, are discussed. New replacement names for Psiloptera (Lampetis) mimosae cyanea (Alfieri 1976) (preoccupied by Psiloptera cyanea (Kerremans 1898), Sambus dohertyi (Théry 1931) (preoccupied by Sambus dohertyi Théry 1926) and Sphenoptera (Buprestochila) purpuriventris Bellamy 1986 (preoccupied by S. (s. str.) purpuriventris Kraatz, in Heyden & Kraatz 1882) are proposed: Lampetis mimosae kubani, nom. nov., Sambus barkeri nom. nov. and Sphenoptera (Buprestochila) malawiensis nom. nov.
