Abstract
The relationship between the antennal club and the antennal sensilla in Crematogaster ants is examined by scanning electron microscopy. A total of 140 worker specimens of 14 species of Crematogaster are examined. Crematogaster workers have the sensilla basiconica, s. tricodea (chaetica), s. coeloconica, s. ampullacea and s. trichodea curvata on the antennal flagellomeres. In general, the s. basiconica are distributed on the surface of antennal club segments. The sensilla are observed on non-club segments in some species, while the sensilla trichodea curvata are distributed on club segments in all specimens examined. Phylogenetic implications of the sensilla morphology are also discussed.
