Abstract:

This study reanalyses some morphological and ultrastructural aspects of three Bunonema species. Specimens of B. penardi, B. hessi and B.franzi were studied using light microscopy and SEM. Bunonema franzi was also studied by TEM. The male of B. penardi is described, this being the first record of males in the genus Bunonema. Additional morphometric data on the females of this species are presented. SEM pictures show details of the deviant amphid position within the Bunonematidae. In contrast to earlier reports, our TEM results show that the evagination of the cuticle in ridges and tubercles is due to the thickening of the median zone of the cuticle. Ultrastructural details of the species-specific polygonal mesh network on the right body side are revealed. The rods that constitute this network lie above the epicuticle and are therefore extracuticular.
