Ixodes signatus nymphs were subjected to the scanning electron microscopy for the observation of the major physiological sense organs including the Hailer's organ. Finger prints and variable sensory setae were found on the body surface, and especially well developed setae were identified on the article IV and on the anal lobes. A central button-like organelle and numerous small holes were found in the spiracular plate. The Haller's organ was identified at the distal point of the tarsus I and regarded as the major sensory organ, chemoreceptor. Tow types of sensory setae were observed, the shorter ones in front of the organ and the longer ones in distal front as well as near behind of the organ. The fully opened organ was ellipsoidal and a total of seven basiconic sensory pegs rooted deeply and shaped as well arranged hook-like was found inside the organ.
