Hemiberlesia pitysophila Takagi is an important forest pest in Southern China. We studied the antennal morphology and sensilla of the male adult H.pitysophila using scanning electron microscope. The antenna of the male adult of H.pitysophila was filiform with 10 segments, which consisted of the scape, pedicel and flagella. There were five types of antennal sensillae found: Bhm bristles, sensilla trichodea， papillary sensilla， sensilla basiconica, and matchshaped sensilla. The matchshaped sensilla is a novel type of sensilla, first described in this species. The number and the distribution pattern of sensillae were different in each antennal segment. The sensilla trichodea was most widely distributed, followed by papillary sensillae; the matchshaped sensillae were the least one.
