Abstract

Taxonomic notes are provided in some Acanthoderini genera. Three new species are described: Scythropopsis intricata Santos-Silva, Botero and Wappes from Mexico, Aegomorphus robustus Santos-Silva, Botero and Wappes and Eupromerella boliviana Santos-Silva, Botero and Wappes from Bolivia. The following synonymies are proposed: PsapharochrusThomson, 1864Thomson, J. 1878. Typi cerambycidarum Musei Thomsoniani. Paris, E. Deyrolle. 21p. as synonym of Aegomorphus Haldeman, 1847; Acanthoderes (Psapharochrus) albomaculatus Fuchs, 1963 and Acanthoderes griseomaculataZajciw, 1971Zajciw, D. 1969a. Contribuição para o estudo da distribuição geográfica do gênero Acanthoderes Serville, 1835 no Brasil (Coleoptera, Cerambycidae, Lamiinae). Atas da Sociedade de Biologia, 12(4): 197-199. as synonyms of Symperasmus alboniger (Bates, 1861); Pteridotelus contaminatus Thomson, 1865 as synonym of Scythropopsis melanostictica (White, 1855); Psapharochrus jameswappesi Tavakilian, 2018 as synonym of Aegomorphus wappesi (Galileo, Martins & Santos-Silva, 2015); and Psapharochrus histrio Casey, 1913 and Psapharochrus guatemalensis Casey, 1913 as synonyms of Aegomorphus circumflexus (Jacquelin du Val, 1857). Acanthoderus circumflexus Jacquelin DuVal, 1857 is proposed as nomen protectum and Acanthocinus rusticus Klug, 1829 as nomen oblitum. Aegomorphus contaminatus (Thomson, 1965) is revalidated. Scythropopsis Thomson, 1864 and Symperasmus Thomson, 1864 are herein elevated to genus rank. The geographical distribution of ten species is expanded and a key to differentiate Acanthoderes, Aegomorphus, Scythropopsis, and Symperasmus is provided.
