A new species of terrestrial planarian (Platyhelminthes: Tricladida: Terricola) from south Brazil.
Geoplana josefi sp. nov. of South Brazil is described herein. The species shows etary polymorphism. Neither youngs nor adults show the characteristic colour pattern of the mature worms. The species has a multilayered lining in the female atrium. The allopatric G. trigueira, which does not have such a lining, is similar externally and internally with adults of G. josefi, its seminal vesicle, however, being unpaired.
