Three new species of Geoplana Stimpson, 1857 from south Brazil, Geoplana ficki sp. nov., G. carbayoi sp. nov., and G. baptistae sp. nov., with dark, nearly homogeneous dorsum, reddish or orange venter, and eyes spreading over the dorsum, are described. The three can be included in the Graff group of “large, broad and flat species”, designated the G. applanatagroup by C. G. Froehlich (1967). The first described species presenting this pattern was G. rufiventris Schultze & Müller, 1857. Later, several other authors described various species exhibiting the “dark dorsal surface and orange or reddish ventral side” pattern. These species constitute an assemblage which will be here designated the G. rufiventris-complex. Apart from presenting a similar pattern, a further considerable difficulty in differentiating these taxa from the other large, broad and flat species of the genus Geoplana which were included in Froehlich’s original G. applanata-group, resides in their possessing a very homogeneous copulatory apparatus. Characteristics of their external and internal morphology are here discussed to simplify the differentiation of sub-groups and comparison of species.

There are several records of the carnivorous behaviour of land flatworms, considered to be top-predators in their micro-habitats, by preying upon various species of invertebrates. However, there is little knowledge of predators on land-flatworms. The possible impact of invasive land flatworms on prey populations has caused widespread concern, when considering their predatory behaviour, combined with recent human influence on the distribution of certain species. This work is the first record of predation on land flatworms by a carnivorous snail. Various-sized land flatworms of 10 native species of the subfamily Geoplaninae, as well as the exotic species Bipalium kewense (subfamily Bipaliinae), were offered to Rectartemon depressus (Gastropoda, Streptaxidae), which accepted all. The predator also fed on the snail Bradybaena similaris. The snails were maintained in laboratory for an average period of 12?months based on a mixed diet of flatworms and B. similaris, suggesting that the snail is a polyphagous predator. Because certain land-flatworm species have been described as invasive species which may have a potential impact on prey populations in native and man-made ecosystems, it is proposed that carnivorous snails of other native species, as potential predators of flatworms, should be tested for possible use in biological control programmes of these invasive planarians.
