Abstract / Introduction / Summary:
Two tramp ant species in the genus Pheidole, i.e., P. magacephala and the P. parva-complex (new to mainland Japan), were found to be already established in mainland Kagoshima, South Japan. They inhabited hotel/residential areas of Ibusuki-shi, Satsuma Peninsula along the coast; P. megacephala nest entrances were seen on the ground surface. In the sites with P. megacephala other ant species were generally scarce, while the P. parva-complex was seemed to be more tolerant toward other species. Among the eight sites surveyed, these two species co-occurred in two sites but from different transects.
