Abstract
We investigated the etiology of a disease of catarina scallop (Argopecten v entricosus (circularis)) during an outbreak in Baja California Sur, B.C.S., Mexico, in the summer of 1995. Samples from Bahia Magdalena and Bahia Conc epcion were studied. Our results indicate that the disease named "pimientil la" is caused by encysted metacercaria of the trematode Stephanostomum sp. The melanized spots in the adductor muscle characteristic of the disease ar e cysts of this trematode. Almost all scallops analyzed had abundant cysts. The characteristics of the matacercariae are described and compared with t hat of other species of Stephanostomum.
