The practice of species delimitation using molecular data commonly leads to the revealing of species complexes and an increase in the number of delimited species. In a few instances, however, DNA-based taxonomy has led to lumping together of previously described species. Here, we delimit species in the genus Cryptogemma (Gastropoda: Conoidea: Turridae), a group of deep-sea snails with a wide geographical distribution, primarily by using the mitochondrial COI gene. Three approaches of species… Expand
Where the snails have no name: a molecular phylogeny of Raphitomidae (Neogastropoda: Conoidea) uncovers vast unexplored diversity in the deep seas of temperate southern and eastern Australia
TLDR
South-eastern Australia appears as a possible hotspot for both raphitomid diversity and endemism, when compared with adjacent areas, and a robust phylogenetic framework is produced and used to delimit genera. Expand
Few and far apart: integrative taxonomy of Australian species of Gladiobela and Pagodibela (Conoidea : Raphitomidae) reveals patterns of wide distributions and low abundance
Abstract. The deep-sea malacofauna of temperate Australia remains comparatively poorly known. However, a recent influx of DNA-suitable material obtained from a series of deep-sea cruises hasExpand
Integrative taxonomy of the Clavus canalicularis species complex (Drilliidae, Conoidea, Gastropoda) with description of four new species
TLDR
This study revisits species delimitation in a morphological cluster of species from the Indo-Pacific referred to as the Clavus canalicularis complex, using an integrative taxonomy approach and finds that in addition to five known species, the complex comprises four new species. Expand

Large‐scale species delimitation method for hyperdiverse groups
TLDR
The formalized strategy applied here outlines an effective and reproducible protocol for large‐scale species delimitation of hyperdiverse groups and identified 27 novel species hypotheses not linked to available species names in the literature. Expand
Delimiting species of marine gastropods (Turridae, Conoidea) using RAD sequencing in an integrative taxonomy framework
TLDR
This work combined both approaches to delimit species in the Xenuroturris/Iotyrris complex, a group of venomous marine gastropods from the Indo‐Pacific, to demonstrate the efficiency of the combined monolocus/multilocus approach to delimite species. Expand
Molecular lineage diversity and inter‐oceanic biogeographical history in Hiatella (Mollusca, Bivalvia)
Hiatella is one of the most widespread marine bivalve genera, occurring in diverse habitats from the temperate to polar latitudes in both hemispheres, and in fossil strata since almost 150 Myr ago.Expand
Distinct genetic differentiation and species diversification within two marine nematodes with different habitat preference in Antarctic sediments
TLDR
The results indicate that gene flow is restricted at large geographic distance in the Southern Ocean, which casts doubt on the efficiency of the Weddell gyre and Antarctic Circumpolar Current in facilitating circum-Antarctic nematode species distributions. Expand
Comprehensive multi-locus phylogeny of Old World tree frogs (Anura: Rhacophoridae) reveals taxonomic uncertainties and potential cases of over- and underestimation of species diversity.
TLDR
It is demonstrated that the taxonomy and evolutionary history of Old-World tree frogs are far from resolved, stable or adequately characterized at the level of genus, species, and/or population. Expand
Species diversity of planktonic gastropods (Pteropoda and Heteropoda) from six ocean regions based on DNA barcode analysis
TLDR
DNA barcodes from the mitochondrial cytochrome c oxidase I subunit gene (COI) from 115 individuals of 41 species sampled from six ocean regions across the globe provide the first multi-regional and species-rich molecular dataset of holoplanktonic gastropods. Expand
Cryptic species in Gemmuloborsonia (Gastropoda: Conoidea)
TLDR
During a broad molecular taxonomic and phylogenetic survey of the gastropod superfamily Conoidea, 80 specimens of several species of the genus Gemmuloborsonia were sequenced for the cytochrome c oxidase subunit I gene, demonstrating the presence of five separate entities, while only four ‘morphospecies' could be isolated by visual examination.

DNA BARCODING AND GENETIC DIVERGENCE IN THE GIANT KELP MACROCYSTIS (LAMINARIALES) 1
TLDR
The authors' molecular data strongly support the recognition of a single species of Macrocystis; therefore, the genus should contain only one species, M. pyrifera, the oldest name. Expand
Molecular and morphological systematics of neustonic nudibranchs (Mollusca : Gastropoda : Glaucidae : Glaucus), with descriptions of three new cryptic species
TLDR
The present paper revises the systematics of Glaucus and provides formal descriptions for three new species in the informal clade ‘Marginatus’ substantiated by species delimitation analyses, and hypothesise that mating behaviour has played a role in cladogenesis in this group. Expand
Genetic and Morphological Divergences in the Cosmopolitan Deep-Sea Amphipod Eurythenes gryllus Reveal a Diverse Abyss and a Bipolar Species
TLDR
The results indicate that, despite the more uniform environment of the abyss and its presumed lack of obvious isolating barriers, abyssal populations might be more likely to show population differentiation and undergo speciation events than previously assumed. Expand
