Abstract The Flabellinidae, a heterogeneous assembly of supposedly plesiomorphic to very derived sea slug groups, have not yet been addressed by integrative studies. Here novel material of rarely seen Arctic taxa as well as North Atlantic, North and South Pacific, and tropical Indo-West Pacific flabellinid species is investigated morpho-anatomically and with multi-locus markers (partial COI, 16S rDNA, 28S rDNA and H3) which were generated and analysed in a comprehensive aeolid taxon sampling… 
Description of a new Moridilla species from North Sulawesi, Indonesia (Mollusca: Nudibranchia: Aeolidioidea)-based on MicroCT, histological and molecular analyses.
A combination of histological, computer tomographic and scanning electron microscopic methods was applied in order to describe and illustrate the anatomy of Moridilla jobeli sp.
Molecular data and updated morphological description of Flabellina rubrolineata (Nudibranchia: Flabellinidae) from the Red and Arabian seas
It is suggested that F. rubrolineata is restricted to only the Red Sea, the Arabian Sea and the Mediterranean Sea and to West Indian Ocean, while specimens from other regions belong to a complex of pseudocryptic species.

A new species of the family Coryphellidae, Coryphella alexanderi sp. nov. is described based on specimens collected in the Kuril Islands, NorthWest Pacific, from the upper sublittoral to 200 m depth.
Young but distinct: description of Eubranchus malakhovi sp.n. a new, recently diverged nudibranch species (Gastropoda: Heterobranchia) from the Sea of Japan
The results show that specimens from the Sea of Japan represent a new species described herein, Eubranchus malakhovi sp.n.
Stripes Matter: Integrative Systematics of Coryphellina rubrolineata Species Complex (Gastropoda: Nudibranchia) from Vietnam
An integrative analysis of the C. rubrolineata species complex based on samples collected in Vietnam waters, combined with available data from other localities of the Indo-West Pacific, confirms the validity of the genus Coryphellina as a distinct taxon and describes four new species.
Integrative taxonomy reveals a cryptic species of the nudibranch genus Polycera (Polyceridae) in European waters
Abstract This work aimed to test whether the colour variability featured by the European nudibranch Polycera quadrilineata is consistent with the concept of a single polychromatic species or may hide
The extraordinary genus Myja is not a tergipedid, but related to the Facelinidae s. str. with the addition of two new species from Japan (Mollusca, Nudibranchia)
Abstract Morphological and molecular data are presented for the first time in an integrative way for the genus Myja Bergh, 1896. In accordance with the new molecular phylogenies, the traditional
A description of Dendronotus shpataki sp. nov. (Gastropoda: Nudibranchia) from the Sea of Japan: a contribution of citizen science to marine zoology
The nudibranch genus Dendronotus Alder et Hancock, 1845 is a common component of boreal and arctic ecosystems, which has recently received a considerable attention due to its high cryptic diversity.
Phestilla subodiosus sp. nov. (Nudibranchia, Trinchesiidae), a corallivorous pest species in the aquarium trade
Based upon a literature review, its original morphological description, and the phylogenetic hypothesis, this species was reclassified as Phestilla chaetopteranacomb, which fell into a well-studied genus, which could facilitate research into its control in reef aquaria.
Biodiversity hotspot in cold waters: a review of the genus Cuthonella with descriptions of seven new species (Mollusca, Nudibranchia)
The molecular phylogeny of the wider traditional “tergipedids” is presented and shows that Cuth onella-like aeolidaceans form a distinct molecular clade as the family Cuthonellidae Miller, 1977, corroborated by reliable morphological apomorphies.


Ontogeny as an important part of integrative taxonomy in tergipedid aeolidaceans (Gastropoda: Nudibranchia) with a description of a new genus and species from the Barents Sea
The “ Eolis ” pustulata species complex is particularly investigated, including description of a new ontogenetically different species Zelentia ninel sp.
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.
A Tale That Morphology Fails to Tell: A Molecular Phylogeny of Aeolidiidae (Aeolidida, Nudibranchia, Gastropoda)
This study, the most comprehensive for Aeolidida to date, uses new sequences of two mitochondrial (COI and 16S) genes and one nuclear gene to resolve the systematic relationships within the Aeolidiidae at a generic level, requiring changes in the systematics of this family.
Aeolid nudibranchs (Gastropoda: Opisthobranchia) of the families Flabellinidae and Eubranchidae from New Zealand waters
Four aeolid species, all newly recorded for New Zealand waters, are described and a new genus, Paracoryphella, and family, the Paracories, are created for Coryphella islandica Odhner.
A Radical Solution: The Phylogeny of the Nudibranch Family Fionidae
The present study is the first molecular phylogeny of Tergipedidae based on partial sequences of two mitochondrial (COI and 16S) genes and one nuclear gene (H3) and it does not recover the traditional systematic relationships at a generic level, and therefore, systematic changes are required.
Phylogenetic systematics and zoogeography of Australian nudibranchs
The genus Codiva Macnae, 1954, which is redefined and its scope restricted to embrace two (probably three) species, is relatively advanced within both the superfamily Aeolidoidea and family Facelinidae and the Glaucidae Ferussac, 1822 deserves separate familial ranking because of numerous apomorphies acquired during the evolution of its novel pleustonic life style.
Two new species of nudibranchiate molluscs from the west coast of North America, with a revision of the family Cuthonidae
Two species of nudibranch molluscs are described from the northeastern Pacific Ocean on the west coast of North America and differences in structure of the radula, reproductive system and other morphological aspects are described.
A new nudibranch species, genus Flabellina (Opisthobranchia: Aeolidacea) from the Caribbean with redescriptions of F. verta (Marcus 1970), and F. dushia (Marcus and Marcus, 1963)
Flabellina dushia (Marcus and Marcus, 1963), originally described from Curaçao in the Caribbean Sea, has recently been redescribed from the eastern tropical Atlantic by Ortea, Caballer and Morro (2004).
Revision of the systematics of Babakina Roller, 1973 (Mollusca: Opisthobranchia) with the description of a new species and a phylogenetic analysis
The results demonstrate that the three described species of Babakina Roller, 1973 are differentiated by external and internal anatomical differences, and preliminary phylogenetic analysis indicates that Babakinidae represents a monophyletic taxon.
