BackgroundThe Euthyneura are considered to be the most successful and diverse group of Gastropoda. Phylogenetically, they are riven with controversy. Previous morphology-based phylogenetic studies have been greatly hampered by rampant parallelism in morphological characters or by incomplete taxon sampling. Based on sequences of nuclear 18S rRNA and 28S rRNA as well as mitochondrial 16S rRNA and COI DNA from 56 taxa, we reconstructed the phylogeny of Euthyneura utilising Maximum Likelihood and… 
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.
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.
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.
The long way to diversity--phylogeny and evolution of the Heterobranchia (Mollusca: Gastropoda).
TLDR
This molecular phylogenetic investigation provides the most comprehensive molecular study of relationships within the Heterobranchia to date and yields substantial insights into the evolution and phylogeny of this enigmatic taxon.
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
Molecular phylogenetic analysis of mudflat snails (Gastropoda: Euthyneura: Amphiboloidea) supports an Australasian centre of origin.

    Molecular phylogenetics and evolution
  • 2012
TLDR
Analysis of molecular data supports revision of the classification of Amphiboloidea to comprise two families and indicates a plesiomorphic distribution and centre of origin in Australasia.
Phylogenetic relationships and evolution of pulmonate gastropods (Mollusca): new insights from increased taxon sampling.
TLDR
Phylogenetic relationships among higher clades of pulmonate gastropods are reconstructed based on a data set including one nuclear marker and two mitochondrial markers for a total of 96 species, with a special emphasis on sampling the Ellobiidae, Onchidiidae, and Veronicellidae.
Bye bye "Opisthobranchia"! A review on the contribution of mesopsammic sea slugs to euthyneuran systematics
TLDR
The present study combines the published and unpublished topologies, and indicates that monophyletic Rhodopemorpha cluster outside of Euthyneura among shelled basal heterobranchs, acteonids are the sister to rissoellids, and Nudipleura are the basal offshoot of EUTHyneura.
Ringiculid bubble snails recovered as the sister group to sea slugs (Nudipleura)
TLDR
Surprisingly, both molecular and morphological features present compelling evidence for the common ancestry of ringiculid snails with the highly dissimilar Nudipleura—the most species-rich and well-known taxon of sea slugs (nudibranchs and pleurobranchoids).
Molecular phylogeny of the Ellobiidae (Gastropoda: Panpulmonata) supports independent terrestrial invasions.
TLDR
The resulting phylogenetic trees support the previous hypothesis that the Ellobiidae are monophyletic only if the Trimusculinae (Otina, Smeagol and Trimusculus) are considered part of this family, and it is found that the Carychiinae, Ellobiinae and Pythiinae are reciprocally monophyletsic and closely related.

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.
Evolutionary relationships of euthyneuran gastropods (Mollusca): a cladistic re-evaluation of morphological characters
TLDR
Morphological characters of the Euthyneura available from the literature were re-evaluated in terms of terminology and primary homology and it appeared that the data matrix was highly homoplastic, and only robust nodes were retained in a concensus tree.
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.
Systematic position of the pelagic Thecosomata and Gymnosomata within Opisthobranchia (Mollusca, Gastropoda) – revival of the Pteropoda
TLDR
Maximum parsimony, maximum likelihood, distance as well as Bayesian analysis of a combined dataset of the three genes reveals that Thecosomata and Gymnosomata are sister groups and together are closely related to Anaspidea.

TLDR
There is no clade present in the analyses corresponding to the taxon Opisthobranchia in the traditional sense, and the use of this name is probably better abandoned altogether.
Molecular phylogeny of a circum-global, diverse gastropod superfamily (Cerithioidea: Mollusca: Caenogastropoda): pushing the deepest phylogenetic limits of mitochondrial LSU rDNA sequences.
TLDR
The molecular phylogeny shows support for the monophyly of the marine families Cerithiidae [corrected], Turritellidae, Batillariidae, Potamididae, and Scaliolidae as currently recognized and reveals that freshwater taxa evolved on three separate occasions.
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.
A molecular phylogeny of Planorboidea (Gastropoda, Pulmonata): insights from enhanced taxon sampling
TLDR
The present study found that Ancylidae as traditionally understood, i.e. covering most freshwater limpet gastropods, is paraphyletic, as the genera of Burnupia and Protancylus have been shown to lie phylogenetically outside the Ancylini.
Initial results on the molecular phylogeny of the Nudibranchia (Gastropoda, Opisthobranchia) based on 18S rDNA data.
TLDR
Phylogenetic analyses of more than 50 gastropod taxa provide strong evidence for support of the monophyly of the Nudibranchia and hypotheses about nudibranch phylogeny inferred from morphological data are compared.
Reconstruction of the phylogeny of the opisthobranchia (Mollusca:Gastropoda) by means of 18S and 28S rRNA gene sequences
TLDR
The opisthobranch subgroups, including the Acochlidiacea, were confirmed as monophyletic in most analyses, whereas monophyly vs paraphyly of Opisth Hobranchia could not be resolved.
