Scanning electron microscopic study of the vulva of some trichurids (Nematoda).
The structure of vulva of four Trichocephalus species has been studied using scanning electron microscopy (SEM). The shape of vulva and cuticular elements on vulval appendages is described and documented. The cuticular structures on the vulva have a characteristic shape specific for each species. It is suppossed that SEM can be successfully employed in a detailed study of vulval structure, which is an important taxonomic character for the differentiation of females of Trichocephalus species.
