Abstract

In order to elaborate a planorbid chart of the State of Rio de Janeiro a survey of freshwater gastropods in the Metropolitan Mesoregion of this State was performed and revealed the occurrence of 20 species: Antillorbis nordestensis check for this species in other resources (Lucena, 1954); Biomphalaria glabrata check for this species in other resources (Say, 1818); Biomphalaria schrammi check for this species in other resources (Crosse, 1864); Biomphalaria straminea check for this species in other resources (Dunker, 1848); Biomphalaria tenagophila check for this species in other resources (Orbigny, 1835); Burnupia check for this species in other resources sp.; Drepanotrema anatinum check for this species in other resources (Orbigny, 1835); Drepanotrema cimex check for this species in other resources (Moricand, 1839); Drepanotrema lucidum check for this species in other resources (Pfeiffer, 1839); Ferrissia check for this species in other resources sp.; Gundlachia ticaga check for this species in other resources (Marcus & Marcus, 1962); Heleobia davisi check for this species in other resources Silva & Thomé, 1985; Lymnaea columella check for this species in other resources Say, 1817; Melanoides tuberculatus check for this species in other resources (Müller, 1774); Physa cubensis check for this species in other resources Pfeiffer, 1839; Physa marmorata check for this species in other resources Guilding, 1828; Pomacea check for this species in other resources sp.; Pomacea canaliculata check for this species in other resources (Lamarck, 1822); Pomacea lineata check for this species in other resources (Spix, 1827) and Pomacea sordida check for this species in other resources (Swainson, 1823). Among the planorbid species B. tenagophila check for this species in other resources was the most frequent, occurring in all municipalities surveyed. The present study extends the distribution of B. straminea check for this species in other resources in the State of Rio de Janeiro and reports new records for A. nordestensis check for this species in other resources , B. schrammi check for this species in other resources , G. ticaga check for this species in other resources , H. davisi check for this species in other resources and the genera Burnupia and Ferrissia. An account about the current transmission areas of schistosomiasis mansoni in this Mesoregion is presented as well.
