Abstract

Specimens of elasmobranch fishes, captured in the states of Paraná and Santa Catarina, of the southern coast off Brazil, represented by three families, four genera, and four species, were parasitized with otobothrioid trypanorhynch cestodes: Heptranchias perlo check for this species in other resources (Bonnaterre, 1788), Squalus check for this species in other resources sp. and Carcharhinus signatus check for this species in other resources (Poey, 1868) were parasitized with Progrillotia dollfusi check for this species in other resources Carvajal & Rego,1987; Prionace glauca check for this species in other resources (Linnaeus, 1758) with Molicola horridus check for this species in other resources (Goodsir, 1841) Dollfus, 1942. Details of internal morphology and/or scolex and/or proglottids surface ultrastructure, that expanded the description of M. horridus, through observations with lightfield, and/or scanning eletronic microscopy, are provided. The known geographical distribution for the species M. horridus is enlarged. P. dollfusi is reported for the first time in elasmobranchs.
