Beyond assumptions: taxonomic and nomenclatural notes on Eburiini (Coleoptera, Cerambycidae, Cerambycinae)

Eleutho Thomson, 1864, is synonymized with Eburia Lacordaire, 1830. A lectotype is designated for Cerambyx quadrimaculatus Linnaeus, 1767, and its true identity is discussed and established. The type species of Dissacanthus (currently considered a synonym of Eburia) and the synonymy between Cerambyx quadrimaculatus Fabricius, 1775, and Cerambyx quadrimaculatus Linnaeus, 1767, are discussed. Coeleburia Thomson, 1861, and Drymo Thomson, 1864, are revalidated. Almost all species currently allocated to Eburia are transferred to Coeleburia. Solangella Martins, 1997, is synonymized with Coeleburia, and Pantomallus meridanus Bates, 1872, returns to the original combination; the impossibility of locating the holotype of P. meridanus is discussed. The following specific synonymies are proposed: Eburia binodosa Gahan, 1895, is considered a junior synonym of E. thoracica (White, 1853); Eburia bauri Linell, 1899, is synonymized with Pantomallus proletarius (Erichson, 1847); Eburia porulosa var. porifera Bates, 1892, is synonymized with Eburia porulosa Bates, 1892; Eburia sexnotata Boheman, 1859, is transferred to Beraba Martins, 1997, and Beraba moema Martins, 1997, is considered its junior synonym. Cerambyx ramphygeus Linnaeus, 1767, is revalidated, and the origin of the description is revealed for the first time. The problematic allocation of Eburia pedestris White, 1853, is discussed, and notes on Eburia tetrastalacta White, 1853, are provided. Coeleburia rufobrunnea Perroud, 1855, is redescribed based on a male; the status of its type material is corrected, and one of the syntypes is illustrated for the first time. The correct illustration of Coeleburia pilosa (Erichson, 1834) in the original description is reinforced. The identity of Eburia sexnotata sensu Martins (1997) is corrected.
