Revised Classification, Nomenclator and Typification of Gastropod and Monoplacophoran Families
TLDR
A fully ranked, hierarchical classification summarizes recent advances in the phylogeny of the Gastropoda and Monoplacophora.

Vetigastropod phylogeny and a new concept of Seguenzioidea: independent evolution of copulatory organs in the deep‐sea habitats
TLDR
Bayesian and maximum‐likelihood phylogenies of Vetigastropoda were reconstructed by separate and combined analyses of one mitochondrial, one nuclear and two nuclear gene sequences, with an emphasis on dense taxonomic sampling.

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.

Major adaptive radiation in neritopsine gastropods estimated from 28S rRNA sequences and fossil records
  • Y. Kano, S. Chiba, T. Kase
  • Biology, Environmental Science
    Proceedings of the Royal Society of London…
  • 7 December 2002
TLDR
It is suggested that the Neritopsina originated in subtidal shallow waters, invaded the land and became fully terrestrial at least three times in different clades, by the extinct Dawsonellidae in the Late Palaeozoic and by the Helicinidae and Hydrocenidae inThe Mesozoic.

Gastropods from Recent Hot Vents and Cold Seeps: Systematics, Diversity and Life Strategies
Since the first discovery of hydrothermal vents at the Galapagos Spreading Center in 1977, gastropods have gained considerable attention as a major constituent of the chemosynthesis-based biological…

Genetic exchange between anchialine cave populations by means of larval dispersal: the case of a new gastropod species Neritilia cavernicola
TLDR
This migration model, based on marine larval dispersal, may be widely applicable to anchialine stygobites with insular distributions, as many such organisms (including shrimps, crabs and fishes) are phylogenetically allied to amphidromous species.

The Continuing Debate on Deep Molluscan Phylogeny: Evidence for Serialia (Mollusca, Monoplacophora + Polyplacophora)
TLDR
A new molecular clock indicates that molluscs had a terminal Precambrian origin with rapid divergence of all eight extant classes in the Cambrian, and the recovery of Serialia as a derived, Late Cambrian clade is potentially in line with the stratigraphic chronology of morphologically heterogeneous early mollusc fossils.

Morphological, ecological and molecular characterization of the enigmatic planispiral snail genus Adeuomphalus (Vetigastropoda: Seguenzioidea)
TLDR
Examining newly collected and museum-stored specimens from upper to lower bathyal depths in the Atlantic, Mediterranean, Pacific and Indian Oceans and recognizing seven recent species revealed six monophyletic groups in Seguenzioidea: Seguenziidae, Chilodontidae, Calliotropidae, Cataegidae, Spinicalliotropis and skenei- morph seguenzIOids.

Microanatomy, shell structre and molecular phylogeny of Leptogyra, Xyleptogyra and Leptogyropsis (Gastropoda: Neomphalida: Melanodrymiidae) from sunken wood
TLDR
It is argued that Neomphalida is a separate basal clade of rhipidoglossate Gastropoda, where the small, helicoid genus Melanodrymia shows most similarities, and supported by shell structure (in particular by the presence of shell pores similar toNeomphalus), and by the molecular trees.

18S rRNA phylogeny of sea spiders with emphasis on the position of Rhynchothoracidae
TLDR
The phylogenetic relationships among all living families of sea spiders are investigated using nearly complete 18S rRNA sequences from 57 ingroup species and five chelicerates under the Bayesian and maximum likelihood methods, suggesting that extended paternal care of offspring evolved only once in Pycnogonida.
