The antennae of two Oxysarcodexia species were analysed using scanning electron microscopy. The morphology of the antennae is typical of cyclorrhaphan flies with the proximal scape, intermediate pedicel, and distal flagellum. The flagellum of Oxysarcodexia corolla has a pronounced waist due to the thickening of its proximal and distal ends. The postpedicel of O. peltata does not have a distinct waist and maintains a uniform thickness from proximal to distal ends. The postpedicel of both Oxysarcodexia species bears trichoid, basiconic, clavate, auriculate, and coeloconic sensilla. Bottle-like sensilla were observed on the female of O. peltata. We seek to add to the knowledge of morphology of antennae of Sarcophagidae species in the Caribbean.
