title: [Tyrrhenia blennii g.n. sp. n. (Hemiurata : Halipegidae Poche, 1925) parasite of Blennius gattorugine and Blennius sanguinolentus].
abstract: Trematodes recovered from Blennius gattorugine and Blennius sanguinolentus from the Gulf of Gaeta, Italy, are described and figured as Tyrrhenia blennii g.n. sp.n. The new genus differs from other members of the Arnolinae Skrjabin and Guschanskaja, 1958 (Halipegidae Poche, 1925) chiefly in having acetabulum equatorial, receptaculum seminis uterinum present and eggs without filaments. The diagnosis of the new genus Tyrrhenia and a key to genera of Arnolinae are given.
