Abstract: The morphology of the cuticular ridges (synlophe) of the intestinal nematode of Japanese lagomorphs, Heligmonella leporis (SCHULZ, 1931) DURETTE-DESSET, 1971 (Heligmonellidae : Trichostrongyloidea) was examined. There were no morphological differences, except the minute differences of the dorsal and exter-no-dosal rays and the distal end of the spicules, among the three populations of H. leporis collected from three species of hosts, Lepus timidus ainu in Hokkaido, Lepus brachyurus brachyurus in Fukuoka Prefecture and Pentalagus furnessi in Amami-Ohshima Island. The number of ridges at the midbody of H. leporis was always 13 in both sexes within the populations of H. leporis. In cross sections of the body, the axis of orientation of cuticular ridges was subfrontal, and a small carene supported by two ridges existed on the left lateral aspect. These synlophe characteristics were different from the genus Heligmonella MONNIG, 1927 classified by DURETTE-DESSET (1971,1983), suggesting that H. leporis should be classified as belonging to subfamily Brevistriatinae. The small but consistent number of cuticular ridges of H. leporis seemed to be a consistent and primitive morphologic characteristic within the family Heligmonellidae.
