title: [Discovery of an endocupola in a nematode of genus Cephalobellus (Oxyurata, Thelastomatidae)].
abstract: One male of Cephalobellus sp. from the hind-gut of Levisonus thaum is described from the Shkotovsky region of the Primorje territory. It has endokupol, a complex of cephalic structures formed by the inner cuticular layer of the cephalic end. The stomatoidal ring of the endokupol is fixed to stomatorhabdia supporting the stoma. The comparison of endokupols of Cephalobellus sp. and those of marine nematodes shows their homology; an opinion is expressed on the independent (parallel) origin of endokupol of Cephalobellus sp.
