The city suits them well: five new species of land planarians (Platyhelminthes: Geoplanidae) living in urban and peri-urban areas

<p>The present study describes five new species of land planarians, inhabiting urban and peri-urban areas from Argentina and Brazil. <i>Paraparaba pampeana</i> sp. nov., <i>Paraparaba platense</i> sp. nov., <i>Pasipha silvanae</i> sp. nov., and <i>Pasipha rara</i> sp. nov. were found in central eastern Argentina (provinces of Buenos Aires and La Pampa), and <i>Paraparaba santiaguense</i> sp. nov. was found in southern Brazil (state of Rio Grande do Sul).

The specimens were found in backyards, nursery gardens, parks, and remnants of the Atlantic Forest in a farm, and were studied by analysing their external appearance, internal anatomy, and molecular data by using the mitochondrial cytochrome c oxidase subunit I (Cox-1). The three new species of the genus <i>Paraparaba</i> and the two new species of the genus <i>Pasipha</i> resemble each other in their external appearance and internal anatomy.
