The distribution of the types of sensillae in the adult red palm weevil, Rhynchophorus ferrugineus (Oliv.) (Coleoptera: Curculionidae), was studied using scanning electron microscopy. Five types of sensillae can be identified on the antenna, with no apparent differences between sexes. These are: multiporous peg sensillae, sensillae trichoïdea (I and II); sensillae basiconica (type I, II and III) and sensillae styloconica. The distal segment of the maxillary palp bears 22 sensillae basiconica in the female, 13 in the male.The upper and lower incisor cusps of the mandibles of the male are relatively longer and more rounded, with an angle of 45° or more where the inner margins of the cusps meet. In the female, the upper and lower cusps are slightly shorter, with an angle of about 45°. In the buccal cavity of females, groups of finger-like sensillae basiconica of various length and shape project toward the centre of the oral opening. In the male, multiporous peg sensillae are found. Sensillae trichoidea are present on the ventral and dorsal sides of the first, second and third tarsal segments distally. These are much denser on the male than the female. On the terminal (9th) abdominal segment of the ovipositor, sensillae are distributed on the dorsal plate, medial plate, ventral plate and anal leaflets (paired). Sensillae of four types occur on the anal leaflets.
