The Acteonoidea are a taxon of about 150 species with uncertain systematic affinity. They have been variously regarded as basal Opisthobranchia, as Architectibranchia, or placed basal to Opisthobranchia together with other heterobranch clades with uncertain interrelationships. We performed molecular phylogenetic analyses employing four gene markers (nuclear 18S rDNA and 28S rDNA; mitochondrial 16S rDNA and COI) to reassess the phylogenetic position of Acteonoidea and provide the first…

On the origin of Acochlidia and other enigmatic euthyneuran gastropods, with implications for the systematics of Heterobranchia

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.

Neactaeonina argentina, New Species, and Family Placement of the Genus Neactaeonina Thiele, 1912 (Mollusca: Gastropoda)

The present study provides the first information on the anatomy and histology of the genital system, and details of the radula anatomy of Neactaeonina, both unknown to date, as well as some characters present in acteonid genera other than Acteon.

Revised Classification, Nomenclator and Typification of Gastropod and Monoplacophoran Families

A fully ranked, hierarchical classification summarizes recent advances in the phylogeny of the Gastropoda and Monoplacophora.

Insights from enigmatic clades - comparative microanatomy and evolution of the Heterobranchia (Mollusca, Gastropoda)

An integrative taxonomic workfl ow for delimiting potentially cryptic and elusive mesopsammic species, that also may be of use for other rare(ly) sampled invertebrates is presented.

First Records of Four Exotic Slugs in Argentina

New and potentially useful DNA sequence data obtained from morphologically-confirmed specimens should assist in making a rapid identification of these exotic slugs by nonspecialists and governmental authorities who are responsible for managing and controlling the presence of exotic species.

Northeast Pacific benthic shelled sea slugs

A compendium of the northeast Pacific benthic shelled sea slugs formerly classified in the paraphyletic group “Opisthobranchia” is provided, and three new species are described in this paper: Microgly Memphis michelleae new species, Microglyphis sabrinae new species and Bogasonia jennyaenew species.

Distribution and morphology of defensive acid-secreting glands in Nudipleura (Gastropoda: Heterobranchia), with an emphasis on Pleurobranchomorpha

This work investigates and compares defensive acid-secreting cell types of various genera within the heterobranch taxon Pleurobranchomorpha by analysing the sizes and distribution of the secretory epithelial cells and subepithelial glands of the epidermis, and investigates the median buccal gland (MBG).

3D reconstruction of the anatomy of the ovoviviparous (?) freshwater gastropod Borysthenia naticina (Menke, 1845) (Ectobranchia: Valvatidae)

The generally accepted taxonomic status of Borysthenia as a genus distinct from Valvata is doubtful, and the family Valvatidae is in need of a thorough systematic revision.

Molecular and morphological analyses reveal pseudocryptic diversity in Micromelo undatus (Bruguière, 1792) (Gastropoda: Heterobranchia: Aplustridae)

The genus Micromelo (family Aplustridae) occurs in almost all tropical and subtropical waters across the globe, with the exception of the Eastern Pacific. Most authors consider Micromelo undatus (B...

Reconstruction of the phylogeny of the opisthobranchia (Mollusca:Gastropoda) by means of 18S and 28S rRNA gene sequences

The opisthobranch subgroups, including the Acochlidiacea, were confirmed as monophyletic in most analyses, whereas monophyly vs paraphyly of Opisth Hobranchia could not be resolved.

New clades of euthyneuran gastropods (Mollusca) from 28S rRNA sequences.

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.

Origins and relationships of primitive members of the Opisthobranchia (Mollusca: Gastropoda)

An examination of possible prosobranch precursors of opisthobranchs and pulmonates suggests that archaeogastropods are poor candidates, as they lack the complex female glands which characterize all…

The Heterobranchia –a new concept of the phylogeny of the higher Gastropoda

The evolutionary pathway is cladistically analysed from a common prosobranch ancestor up to the basal pulmonates and a new classification according to (but not identical with) the reconstructed cladogram is presented.

From sea to land and beyond – New insights into the evolution of euthyneuran Gastropoda (Mollusca)

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.

Molecular phylogeny of euthyneura (mollusca: gastropoda).

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.

Evolutionary relationships of euthyneuran gastropods (Mollusca): a cladistic re-evaluation of morphological characters

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.

American opisthobranch mollusks

A large collection of gastropods belonging to the Museum of the Institute of Marine Sciences of the University of Miami, it contains two species of prosobranchs belonging to families traditionally studied together with opisthobranchs, and the majority of the animals came from Florida and the West Indies, although some were collected on the Pacific side of the Canal Zone.
