A planarian belonging to the group D. gonocephala s.l. was found in 13 sites in Sardinia (11 in the catchment area of the Rio Mannu of Porto Torres and 2 in that of the Coghinas). It is morphologically related to D. benazzii Lepori of Sardinia and Corsica but presents a different karyotype: 2n = 14; n = 7 chromosomes instead of 2n = 16; n = 8 chromosomes. The latter is the most common in the superspecies D. gonocephala of central European and Mediterranean distrubution areas. The planarian in question was considered a distinct species with the group D. gonocephala s.l. and the denomination D. hepta sp. nov. is proposed.

Dugesia leporii sp. n. from SW Sardinia is described. It is characterised by a comparatively small copulatory apparatus, the shape of the penial papilla, and the course and opening of the ejaculatory duct. The penial papilla, which has a penial valve, protrudes into an undivided atrium and is not provided with accessory structures. The taxonomic position of the new species within the D. gonocephala group is discussed.

A new species of Dugesia from East Africa is described as a first report of Platyhelminthes from Lake Tana. Dugesia aethiopica sp. n. is characterized by the shape of its bursa copulatrix; length, diameter, course, and opening of the bursal canal; opening of the oviducts; shape of the penis papilla; penial parenchymatic cavity. The taxonomic position of the new species within the D. gonocephala group is discussed in comparison with the other African and Madagascan species.

Planarians of the genus Dugesia have a worldwide distribution with high species diversity in the Mediterranean area. In this area, populations with a triploid karyotype that reproduce by fissiparity are exceptionally frequent, outnumbering the sexual populations. This situation poses interesting questions, such as the age of these asexual lineages, whether they all belong to the same species or whether the triploidization event is recurrent, and what factors (climatic, geographical, historical...) explain the prevalence of these asexual forms. However, asexual populations cannot be assigned to a species due to the lack of copulatory apparatus - the main structure used in species identification. In this study, we have developed a DNA barcoding method, based on COI and ITS-1 sequences, which allows the assignment of the fissiparous forms to sexual species. At the same time, phylogenetic analysis from species of the western Mediterranean have unveiled the presence of species with highly differentiated populations alongside species with a wide distribution and almost no genetic variation. The roles of habitat instability, dispersal capacity and human activities are briefly discussed.
