Because Onchidiidae (Mollusca: Gastropoda: Pulmonata) has been understudied since the last experts were active more than 70 years ago, systematics of this taxon is in a state of confusion: The nomenclatural status of most species names is unknown; the current supra-specific classification, largely based on Labbe’s work, has not been revised since the 1930s and needs to be re-evaluated through a modern, phylogenetic approach. A checklist of all 143 species names available in Onchidiidae is… 

Integrative taxonomy of the genus Onchidium Buchannan, 1800 (Mollusca, Gastropoda, Pulmonata, Onchidiidae)

The genus Onchidium is redefined here as a clade including only three species which are strongly supported by both morphological and molecular data, and all three species are re-described here for the first time.

A new genus and a new species of onchidiid slugs from eastern Indonesia (Gastropoda: Euthyneura: Onchidiidae)

A new genus is described here for a new species, Alionchis jailoloensis Goulding & Dayrat, new species which is highly distinct from all other onchidiids, which is endemic to Halmahera, eastern Indonesia.

A new species and new records of Onchidium slugs (Gastropoda, Euthyneura, Pulmonata, Onchidiidae) in South-East Asia

A new species of Onchidium melakense is described, a rare species with only nine individuals found at three mangrove sites in the Andaman Islands and the Strait of Malacca, which is delineated based on mitochondrial (COI and 16S) and nuclear (ITS2 and 28S) DNA sequences as well as comparative anatomy.

Systematic revision of the genus Peronia Fleming, 1822 (Gastropoda, Euthyneura, Pulmonata, Onchidiidae)

The taxonomy of the onchidiid slugs with dorsal gills is revised for the first time based on a large collection of fresh material from the entire Indo-West Pacific, from South Africa to Hawaii, to better establish species distributions.

Description of a new Peronia species (Gastropoda: Eupulmonata: Onchidiidae) from Iran, Persian Gulf.

Results on a new species of eupulmonate slug found in the Persian Gulf, a subtropical region with harsh conditions such as elevated salinity and high temperature compared to the Indian Ocean, are presented.

Anatomical Re-Description of the Terrestrial Onchidiid Slug Semperoncis montana (Plate, 1893)

The anatomy of Semperoncis montana, a terrestrial species that lives in high-elevation rain forests of the Philippines Islands, is redescribed based on 91 specimens representing ten populations and Ontogenetic changes in the shape of male organs are described and illustrated in detail, indicating that S. montana was described based on immature specimens of the later named Platevindex apoikistes.

A new genus and four new species of onchidiid slugs from South-East Asia (Mollusca: Gastropoda: Pulmonata: Onchidiidae)

A new genus, Melayonchis Dayrat and Goulding gen. nov., and four new species are described, based on morphological characters and DNA sequences of the Onchidiidae, which ranges from the Andaman Sea to the South China Sea through the Strait of Malacca.

A new genus and three new species of mangrove slugs from the Indo-West Pacific (Mollusca: Gastropoda: Euthyneura: Onchidiidae)

A new genus of onchidiid slugs is described, Paromoionchis Dayrat & Goulding gen. nov., which includes five species, three of which are new, distributed from western India to the subtropical waters of Japan and southeastern Australia.

A revision of Peronina Plate, 1893 (Gastropoda : Euthyneura : Onchidiidae) based on mitochondrial and nuclear DNA sequences, morphology and natural history

Peronina species are described using an integrative approach (natural history, comparative anatomy and DNA sequences), and Mitochondrial COI and 16S sequences and nuclear ITS2 and 28S sequences are used to independently test species boundaries.

Phylogenetic relationships and evolution of pulmonate gastropods (Mollusca): new insights from increased taxon sampling.




The species of New Zealand onchidiidae (mollusca, gastropoda) and their distribution

The present classification of the New Zealand Onchidiidae into six species is shown to be incorrect and three of the species are reclassified under the species name Onchidella nigricans (Quoy and Gaimard).

Distribution of Onchidium damelii Semper (Gastropoda, Onchidiidae)

The pulmonate gastropod Onchidium damelii Semper has a widespread tropical Indo-Pacific intertidal distribution and shows habitat preference rather than a zonal (tidal pattern) distri bution within the mangroves; population density is associated with substrate particle size and organic content; and temperature relationships were investigated.

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.

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.

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.

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.

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.

The Western Atlantic species of Onchidella (Pulmonata)

Three new species from the Florida Keys and Colombia are described, one of which has a symmetrical penial papilla much larger than that of O. armadilla and another two with a penial retractor of type II.

XV.—On the Anatomy of a Collection of Slugs from N.W. Borneo; with a List of the Species recorded from that Region

In the early part of 1900 I received from J. H. Ponsonby, Esq., a small collection of land molluses from N.W. Borneo, with a request that I would investigate and report upon the same, and found it to contain examples of two new genera of great interest.
