Abstract
Emurena ritae Tavares sp. nov. is described from two Atlantic Forest remnants in northeastern Brazil based on morphological and molecular data. This newly discovered species reflects moth diversity in this historically underexplored region and underscores the relevance of continuing investigations in the Atlantic Forest in the course of ongoing biogeographical analyses and species surveys. An updated identification key for the genus Emurena is presented, along with taxonomic and biogeographical remarks that suggest the presence of additional, yet undescribed, cryptic species within the group.
