Two new species of Geoplanidae (Platyhelminthes, Tricladida, Terricola) of south Brazil



Two new species of terrestrial planarians in the family Geoplanidae, Geoplana franciscana and Notogynaphallia guaiana, from the State of Rio Grande do Sul, Brazil, are described. Both species have a multilayered lining in the female atrium. The study of specimens of N. goetschi, aimed at comparing it to N. guaiana, reveals the need for a re-description and review of N. goetschi.
