Abstract. Only seven frenulate species are currently known along the Eurasian coast of the Arctic Ocean. We describe a new genus and a new species of frenulates Crispabrachia yenisey, gen. nov. et sp. nov. The morphological analysis involved standard anatomical techniques, semithin sections and scanning electron microscopy (SEM). The molecular study included four markers (partial COI, 16S, 18S and 28S) and implemented Bayesian and Maximum likelihood phylogenetic approaches. The description of…

Myogenesis of Siboglinum fiordicum sheds light on body regionalisation in beard worms (Siboglinidae, Annelida)
The heteronomous Siboglinum lacks the strict anterior to posterior sequence of segment formation as it is found in the most studied annelid species and may represent an adaptation of these annelids to the settlement and transition to the sedentarian-tubiculous mode of life.


A remarkable pogonophoran from a desalted shallow near the mouth of the Yenisey River in the Kara Sea, with the description of a new species of the genus Galathealinum (Annelida: Pogonophora: Frenulata)
A new species of Pogonophora obtained from one station at a depth of 25 m from near the Dikson Island in the Kara Sea is described. Galathealinum karaense sp. nov. is one of the largest
A revision of the Oligobrachiidae (Annelida: Pogonophora), with notes on the morphology and distribution of Oligobrachia haakonmosbiensis Smirnov
The species redescribed here is shown to have a wider distribution than previously known and the presence of glandular patches confirms the closest morphological affinity between O. haakonmosbiensis and O. webbi, the two North Atlantic pogonophorans of the genus Oligobrachia.

Molecular phylogeny of siboglinid annelids (a.k.a. pogonophorans): a review
The literature to date on siboglinid molecular phylogeny is reviewed and a summary of the clade’s evolution is summarized.
Meloscaphander grandis (Heterobranchia: Cephalaspidea), a deep-water species from the North Pacific: Redescription and taxonomic remarks.
Morphological differences between the genera Meloscaphander and Scaphander are of dubious significance and, when coupled with molecular data, give a strong reason for reconsidering Meloscphander as a junior synonym of Scaphanders.

Four new species of the genus Polarsternium (Smirnov, 1999) are recorded from the Atlantic Sector of the Antarctic Ocean. Benthic samples were collected from depths of 820–6070 m at 10 stations on
Cryptic frenulates are the dominant chemosymbiotrophic fauna at Arctic and high latitude Atlantic cold seeps
It is hypothesized that specific, local geochemical conditions, in particular, high sulfide fluxes and concentrations could account for the unusually high symbiont densities in members of the Oligobrachia sp.
