The city suits them well: five new species of land planarians (Platyhelminthes: Geoplanidae) living in urban and peri-urban areas Lisandro Negrete (530771) Agustina Zivano (17824480) Simón Gigli (25122107) Cristina Damborenea (470875) Francisco Brusa (530773) Evolutionary Biology Environmental Sciences not elsewhere classified Chemical Sciences not elsewhere classified Ecology Sociology Biological Sciences not elsewhere classified Inorganic Chemistry Plant Biology Argentina Brazil land flatworms Paraparaba Pasipha pseudocryptic species <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. They differ only in details of the external appearance (mainly regarding the pigmentation patterns) and minor differences in their internal anatomy, mostly concerning the copulatory apparatus, so they can be considered pseudocryptic species. Genetic distances and species delimitation approaches (ASAP and mPTP) reinforce their specific identity. Although anthropized habitats are sometimes overlooked in biodiversity surveys, they can offer optimal conditions for the establishment of species.</p> 2026-09-28T11:27:23Z Dataset Dataset 10.6084/m9.figshare.34013405.v1 https://figshare.com/articles/dataset/The_city_suits_them_well_five_new_species_of_land_planarians_Platyhelminthes_Geoplanidae_living_in_urban_and_peri-urban_areas/34013405 CC BY 4.0
