Morphological characters of the Euthyneura available from the literature were re-evaluated in terms of terminology and primary homology. A total of 77 characters and 75 taxa were retained in a data matrix. Several assumptions on character weights and types were tested. In the cladistic analyses, it appeared that the data matrix was highly homoplastic, and only robust nodes (those which were little modified by variations in weight and coding of characters) were retained in a concensus tree.

New clades of euthyneuran gastropods (Mollusca) from 28S rRNA sequences.
TLDR
Morphological characters which support the new clades obtained here are discussed and first molecular confirmation of monophylies of Hygrophila, including Chilina, Acteonoidea, and Sacoglossa, which include both shell-bearing species and slugs are discussed.
A new phylogeny of the Cephalaspidea (Gastropoda: Heterobranchia) based on expanded taxon sampling and gene markers.
TLDR
It is suggested that the family level taxonomy of the Cephalaspidea warrants a profound revision and several new family and genus names are required to reflect the new phylogenetic hypothesis presented here.
From sea to land and beyond – New insights into the evolution of euthyneuran Gastropoda (Mollusca)
TLDR
It can be proposed for the first time that invasion of freshwater by Pulmonata is a unique evolutionary event and has taken place directly from the marine environment via an aquatic pathway.
Towards a phylogeny and evolution of Acochlidia (Mollusca: Gastropoda: Opisthobranchia)
TLDR
It is concluded that the acochlidian ancestor was marine mesopsammic, and the formerly enigmatic Ganitidae, resembling sacoglossan opisthobranchs by having dagger-like rachidian radular teeth, are likely to be highly derived microhedylids.
Molecular phylogeny of the Euthyneura (Mollusca, Gastropoda) with spacial focus on Opisthobranchia as a framework for reconstruction of evolution of diet
TLDR
The present study presents the currently most extensive analyses on opisthobranch phylogeny including 58 species from all major subgroups and finds Herbivory is found as the most likely ancestral diet of Euthyneura while carnivory probably evolved several times independently in different clades.
Taxonomy and Cladistic Analysis of Plakobranchidae (Gastropoda: Sacoglossa)
TLDR
The monophyletic status of the genera Plakobranchus van Hasselt, Thuridilla Bergh and Elysia Risso, 1818 was fully supported by all analyses, meaning that old names might be resurrected for a better explanation of the natural history of this genus.
Molecular phylogeny of euthyneura (mollusca: gastropoda).
TLDR
The monophyly of the Euthyneura (Opisthobranchia + Pulmonata) was rejected by the inclusion of the heterostrophan Pyramidella and the phylogenetic utility of two rare genomic changes is addressed.
Molecular phylogeny and evolution of Pulmonata (Mollusca: Gastropoda) on the basis of mitochondrial (16S, COI) and nuclear markers (18S, 28S): an overview
The phylogenetic relationships among the major groups of Pulmonata were studied by the information derived from a concatenated dataset consisting of mitochondrial (16S and COI) and nuclear (18S and
On the origin of Acochlidia and other enigmatic euthyneuran gastropods, with implications for the systematics of Heterobranchia
TLDR
It is demonstrated that the invasion of the meiofaunal habitat has occurred several times independently in various euthyneuran taxa, leading to convergent adaptations previously misinterpreted as synapomorphies.
Phylogenetic relationships among Opisthobranchia (Mollusca: Gastropoda) based on mitochondrial cox 1, trnV, and rrnL genes.
TLDR
The new molecular phylogeny provided a robust framework for comparative studies, and prompted a revision of the morphological synapomorphies diagnosing the main clades within opisthobranchs.

TLDR
The cladogram is used as a basis for a new classification of the Littorinidae, in which three subfamilies and 14 monophyletic genera are recognized, and the poor fossil record of the family is reviewed, and its biogeography discussed in the light of the phylogenetic hypothesis.

TLDR
More than 100 morphological, anatomical and histological characters pertaining to the Nudibranchia are discussed in the course of a phylogenetic analysis and the paraphyly of the ‘Arminoidea’ is demonstrated.

TLDR
Character analysis is performed based on anatomical information on 95 species of Sacoglossa (Mollusca, Opisthobranchia) to establish a monophyletic group and relationships among most genera included in the Placobranchoidea remain unresolved.
