Exploring gene sequences and phylogenetic relationships of four terrestrial planarian species (Platyhelminthes; Tricladida; Geoplanidae) in Europe.

Partial mitochondrial cox1 gene sequences from four recently recognised European species of terrestrial planarians, and ribosomal ITS1 sequences for two of them, are presented: Marionfyfea adventor, Artioposthia exulans (both introduced from New Zealand), Australopacifica atrata (from Australia) and specimens putatively identified as Microplana edwardsi, presumed to be native to the UK. The sequences are compared with those from other terrestrial planarian species and analysed phylogenetically. Results indicate that the sister group of M.

Integrative taxonomy reveals three new species of European Lepidocyrtus lignorum-group (Collembola, Entomobryidae).

Lepidocyrtus is one of the genera of springtails with the largest number of species in the world. Molecular studies carried out to date on this genus have revealed the existence of a large number of cryptic species. Molecular and morphological studies done with four European populations of the genus have allowed us to describe three new species within the L.
