Among species two medical-veterinary importance (Biomphalaria straminea Melanoides tuberculata) four exotic invasive (Corbicula fluminea, C. largillierti, Limnoperna fortunei M. tuberculate). Of 1,473 trematodes, five (0.33%) infected, one specimen contained Vivax, Pleurolophocercous, Virgulate. For first time these six taxa have been described State Sergipe: Drepanotrema depressissimum, D. cimex, lucidum, Ancylidae, Physa acuta largillierti. contributes to knowledge biodiversity distribution limnic addition serving support monitoring prevention bio species, intermediate hosts, since area presented potential helminth transmission.
