“…The taxa Terricola and Paludicola became invalid and were replaced by a new taxon, the Continenticola (Carranza et al, 1998). Later molecular studies (Baguñà et al, 2001;Álvarez-Presas et al, 2008) lent further support to the clustering together of the Terricola and the Dugesiidae and of the Terricola and the Dugesiidae to their sister-group, the Planariidae + the Dendrocoelidae (Planarioidea) (Fig. 4).…”

“…Today, this superfamily houses all the freshwater planarians from the family Dugesiidae as well as all the terrestrial planarians (family Geoplanidae) . The Geoplanoidea are supported by molecular trees based on the two ribosomal genes and mitochondrial cytochrome oxidase I (COI) (Álvarez-Presas et al, 2008), in addition to the presence of a ribosomal gene cluster duplication. In their initial proposal, Carranza and collaborators (1998) suggested the complex eye found in the Dugesidae and in terrestrial planarians as a possible morphological synapomorphy for the group.…”

“…The most recent molecular study of the superfamily (Álvarez-Presas et al, 2008) showed that a single transition occurred from freshwater to the terrestrial habitat (from a common ancestor with the Dugesiidae). The origin of this group is probably more than 100 million years old , and it was likely followed by rapid diversification.…”

Within the free-living platyhelminths, the triclads, or planarians, are the best-known group, largely as a result of long-standing and intensive research on regeneration, pattern formation and Hox gene expression. However, the group's evolutionary history has been long debated, with controversies ranging from their phyletic structure and position within the Metazoa to the relationships among species within the Tricladida. Over the the last decade, with the advent of molecular phylogenies, some of these issues have begun to be resolved. Here, we present an upto-date summary of the main phylogenetic changes and novelties with some comments on their evolutionary implications. The phylum has been split into two groups, and

Sequence data of Cytochrome Oxidase Subunit I (COI) gene of mitochondria were used to elucidate the taxonomy and phylogenetic relationships of the terrestrial planarian taxa in Korea. Published COI gene sequences from Family Bipaliidae in GenBank were also included in the phylogenetic analysis. The aligned data sets for Terricola ranged from 387 to 444 nucleotides (bp) as a result of differences in insert nucleotides. The phylogeny based on COI analysis was not congruenced with the morphological traits. Bipalium nobile included the remainder taxa (Bipalium adventitium, Bipalium venosum, Bipalium kewense, and Bipalium multilineatum). Internal nodes were strongly supported (>91%). The phylogenetic tree on COI analysis showed that most identified species were well separated from each other. The main phylogenetic analysis formed monophyletic groups. COI gene of mitochondria could have the resolving power for taxonomy information for the terrestrial planarian taxa in Korea.

“…A fragment of the gene encoding the mitochondrial cytochrome oxidase I (Cox1) was analyzed by polymerase chain reaction (PCR) together with three nuclear genes: genes encoding the 18S type II rRNA (18S) and 28S rRNA (28S) and a fragment of Elongation Factor 1‐alpha (EF). For 18S and 28S, we used primers and PCR conditions as in Álvarez‐Presas, Baguñà, and Riutort (2008) for Cox1 as in Álvarez‐Presas et al. (2011) and for the EF as in Carbayo et al.…”

Terrestrial flatworms (Platyhelminthes, Tricladida, and Geoplanidae) belong to what is known as cryptic soil fauna of humid forests and are animals not easily found or captured in traps. Nonetheless, they have been demonstrated to be good indicators of the conservation status of their habitat as well as a good model to reconstruct the recent and old events affecting biodiversity. This is mainly due to their delicate constitution, their dependence on the integrity of their habitat, and their very low dispersal capacity. At present, little is known about their communities, except for some studies performed in Brazil. In this work, we analyze for the first time in Europe terrestrial flatworm communities. We have selected two protected areas belonging to the Red Española de Parques Nacionales. Our aims include performing a first study of the species richness and community structure for European terrestrial planarian species at regional and local scale. We evaluate the effect of type of forests in the community composition and flatworms’ abundance, but also have into account the phylogenetic framework (never considered in previous studies) analyzed based on molecular data. We find differences in the species composition among parks, with an astonishingly high diversity of endemic species in the Parque Nacional de Picos de Europa and an extremely low diversity of species in the Parque Nacional de Ordesa y Monte Perdido. These divergent patterns cannot be attributed to differences in physical variables, and in addition, the analyses of their phylogenetic relationships and, for a few species, their genetic structure, point to a more probable historical explanation.
