Cerambycidae is one of the largest families of Coleoptera, with approximately 38,000 species described. Knowledge of Cerambycidae fauna in Brazil has increased in the last 50 years, but some regions, such as the Brazilian semi-arid region, remain relatively unexplored. An updated checklist of Cerambycidae from that region, based on previously published works, checklists, and catalogs, and the study of 331 specimens of 72 species, 58 genera, 26 tribes, and three subfamilies deposited in the collection of the Zoology Museum of the Universidade Estadual de Feira de Santana is provided. This list has 633 species, 303 genera, 58 tribes, of four subfamilies of Cerambycidae from 75 municipalities in nine states in the Brazilian semi-arid region. A map illustrating the distribution of the Cerambycidae species in the semi-arid region is also provided. Four new species are described: Eburodacrys boteroi sp. nov. and Coccoderus costae sp. nov. (Cerambycinae); and Aerenicopsis joseferreirai sp. nov. and Pseudomecas mourai sp. nov. (Lamiinae). The new species are included in an identification key to the respective genus. Furthermore, Antodice kyra Martins & Galileo, 1998 is new record from the Bahia State; Chevrolatella tripunctata (Chevrolat, 1862) is a new record to Brazilian semi-arid region; Colobothea rubroornata Zajciw, 1962 is a new record from Bahia State and Brazilian semi-arid region, and Odontocera bilobata Zajciw, 1965 is a new record from the Bahia State and Brazilian semi-arid region. It is evident that some regions in the Brazilian semi-arid region are poorly sampled and new inventory studies must be carried out.
