Hemilucilia segmentaria (Fabricius, 1805) is a Neotropical blowfly species of forensic importance, with necrophagous and asynanthropic habits. In this study, the antennal ultrastructure of H. segmentaria was examined using scanning electron microscopy. The three antennal segments are covered by microtrichia. Sensilla chaetica were detected only on the scape and pedicel. Setiferous plaques and a pedicellar button were observed on the pedicel. Four types of sensilla were found on the postpedicel, including s. trichoidea, s. basiconica (subtype I, II and III), s. coeloconica subtype I, and sensory pits with s. coeloconica subtype II. This is the first time that the fine structure of the antennae of H. segmentaria was studied. Our results constitute a solid base for research on comparative and functional morphology in H. segmentaria and other blowflies.
