TREMATODOS DE LOS MURCIELAGOS DE MEXICO. IV. DESCRIPCION DE UN NUEVO GENERO DE LA SUBFAMILIA LECITHODENDRIINAE Looss, 1902, Y UNA NUEVA ESPECIE DE PROSTHODENDRIUM Dollfus, 1931

Resumen

In this paper we continue our investigations about the Trematoda, parasites of the bats living in Mexico. A redescription is given of Piagiorchis (Multiglandularis) muris (Tanahe, 1922) Yamaguti, 1933, found for the first time in Japan and later in the bats of the United States, this being the second time that a North American bat is
mentioned as host to this parasite. Another species redescribed is Limatulum limatulum (Braun, 1900) Travassos, 1921, which is mentioned for the first time, as parasite to the bats of Mexico and all North America.
The obtention of new specimens of Limatulum scabrum Caballero, 1940 permited us to re-classify this parasite definitely as Prosthodendrium scabrum (Caballero, 1940).
A new species of Prosthodendrium, Prosthodendrium emollidum is created, which differs from P. naviculum Macy, 1936, and P. chilostomum (Mehlis, 1831), both having the acetabula smaller than the oral sucker in a proportion 1.4 in the size and arrangement of the vitellaria, the size of the eggs, the size of other organs and also of the whole parasite.
A new genus is also created, Ochoterenatrema, which is characterized by the existence of the sexual pore on the left lateral border of the acetabulum, independent of the prostatic body mass. The ovary is lobulated. The vitellaria are confined to triangular anterior area located between the digestive tube, the anterior border of the testicles and the anterior border of the body itself.
