A new species of longhorned beetle, Eburia pirkli sp. nov. Lingafelter, Touroult & Hodecek (Coleoptera: Cerambycidae: Cerambycinae: Eburiini) is described from the Dominican Republic. Many specimens of this sexually dimorphic species were collected in several locations within Pedernales Province on the Bahoruco Peninsula of Hispaniola. We compare this species with the morphologically similar Eburia quadrimaculata (Linnaeus, 1767) and Eburia thoracica White, 1853 (both not recorded from Hispaniola) and provide an identification key to all the Hispaniolan Eburia species.
