A polyvalent and universal tool for genomic studies in gastropod molluscs (Heterobranchia)
Molecular Phylogenetics and Evolution, 2021Molluscs are the second most diverse animal phylum and heterobranch gastropods present ~ 44,000 species. These comprise fascinating creatures with huge morphological and ecological disparity. Such great diversity comes with even larger phylogenetic uncertainty and many taxa have been largely neglected in molecular assessments.

Taxonomy and anatomy of Amphiboloidea (Gastropoda: Heterobranchia: Archaeopulmonata)
Zootaxa, 2007The taxonomy of the pulmonate superfamily Amphiboloidea is investigated with particular reference to Australasian taxa. Anatomical features of the alimentary, reproductive and central nervous systems differ substantially between taxa, and conchological, opercular and radular characters are also described.

Pyramidellidae (Mollusca, Gastropoda, Heterobranchia) of the Faroe Islands
Sarsia, 1995Abstract The pyramidellid fauna of the Faroe Islands is surveyed. Material collected during the BIOFAR and BIOICE programs, the collections in the Zoological museum in Copenhagen as well as collections made by the author are reported. Most of the pyramidellid material mentioned in “The Zoology of The Faroes” has been re-examined.

Systematics of Ophicardelus (Gastropoda: Heterobranchia: Ellobiidae)
Molluscan Research, 2005Ophicardelus is currently used for a small group of estuarine ellobiid snails found in Australia and New Zealand, but a previous study (Hyman et al. 2004) suggested that it may not be monophyletic. In the present study, morphological data are used in a cladistic analysis to test the monophyly of Ophicardelus.

On the genus Armina (Gastropoda: Heterobranchia: Nudibranchia) in Thailand
Marine Biodiversity, 2017The marine sea slug heterobranch fauna from Thailand is composed of a total of 240 species, and Armina semperi is the only representative of the genus Armina recorded in the country. This species, described in the Philippines in the nineteenth century, has an uneasy taxonomic history and appears to be part of a complex of morphologically similar ...

Adriatic ‘opisthobranchs’ (Gastropoda, Heterobranchia): shedding light on biodiversity issues
Marine Ecology, 2016AbstractWe herein review the Adriatic opisthobranch fauna, provide an updated checklist of 223 species and assess their distribution at regional and country levels. New Adriatic records are provided for 67 opisthobranch taxa, adding three new records for the Italian coastline, five new records for Albania, eight for Croatia and 15 for Montenegro.

Heterobranchia (Gastropoda) from the Jurassic Deposits of Russia
Paleontological Journal, 2019Small gastropods from the Jurassic deposits of the European Russia, united into the lower Heterobranchia or Allogastropoda, are described. The families of Ampezzanildidae, Cimidae, Cornirostridae, Ebalidae, and Stuoraxidae are distinguished, and a set of taxa is given without reference to a definite family.

Helicarionidae (Gastropoda: Heterobranchia: Stylommatophora) of Lord Howe Island
Molluscan Research, 2016ABSTRACTThe Helicarionidae of Lord Howe Island are reviewed and described. There are nine species and subspecies of Helicarionidae in four genera (Epiglypta, Gudeoconcha, Howerion and Parmellops), with all taxa endemic to the island. Most species that are confined to the highland parts of the island appear to have declined in recent years relative to ...
