The antennal sensilla and setae of both sexes of A. tenebrosus (Cresson) (Pompilidae) were examined with a scanning electron microscope. Sensilla placodea, corrugated conical sensilla, pit organs, sensilla campaniformia, sensilla trichodea A1, B1, C1, sensilla basiconica and several types of setae were found. They are described and illustrated. The sensilla are rather similar in both sexes, except that females have numerous corrugated conical sensilla which males lack. Sensilla trichodea C1 are found only in the males. While most of the setae are similar in the 2 sexes, the shape and sculpturing of some distinguish males from females.
