Redescriptions, new combinations, synonymies, and new records of South American Lepturini (Coleoptera: Cerambycidae: Lepturinae)

Resumo

Some Neotropical Lepturini are studied: Euryptera latipennis Audinet-Serville, 1828 (type species) redescription, Strangalia dimidiata (Redtenbacher, 1868) new combination (= Strangalia melanophthisis (Berg, 1889) new combination, new synonymy, and lectotype designation), Strangalia fulvicornis (Bates, 1872) new record from Argentina; Strangalia melanura (Redtenbacher, 1868) new combination from Brazil; Strangalia rubricollis (Bates, 1870) new record from Peru. "Leptura" bonariensis Burmeister, 1865 is not a true Leptura, being exotic for Argentina and for the Neotropical fauna; the type-specimen was mislabelled as coming from Buenos Aires. Elytral patterns, posterior tarsi, antennae, 5th apparent urosternite, and elytral apices of E. latipennis, and S. dimidiata are illustrated. A key to Argentinian genera and species is provided.
