The little-known Neotropical tortricid moth Lasiothyris luminosa (Razowski& Becker) is reported for the first time as a grapevine pest in Northeastern Brazil. A diagnosis based on morphological characters including the genitalia is provided for both sexes, together with a preliminary description of economic damage caused by the larval stage. In addition, we sequenced a partial region of the cytochrome oxidase subunit I gene from specimens from the region, and reconstructed phylogenetic relationships using representative lineages of closely related tortricids as terminals. The larvais endophagous, feeding on the inflorescence from closed buds before flower anthesistoopen flowers and later, inside fruits at different maturation stages, causing them to rot. Preliminary surveys carried out on a few farms indicate that the effective damage may reach circa 10% of table-grape production in the region.
