Abstract | |||||||||||||||||
| Biomphalaria tenagophila tenagophila (Orbigny 1835) is a planorbid susceptible to infection with Schistosoma mansoni which occupies a wide range in South America and is an important intermediate host in some areas of Brazil. This species can not be differentiated from B. occidentalis or B. tenagophila guaibensis by shell characteristics nor morphology of most organs of the genital system. However only B. t. tenagophila and B. occidentalis are separated by absolute reproductive isolation . So far no reports have been published about reproductive isolation between B. t. tenagophila and B. t. guaibensis or between B. t. guaibensis and B. occidentalis. | |||||||||||||||||
