Eight new species of cirratulid polychaetes of the genus Chaetozone from the Alaskan (Beaufort Sea) and Canadian Arctic (Baffin Island, Baffin Bay, Labrador, Hudson Strait, and Hudson Bay) and the Northeastern Pacific are reported together with two new species of Tharyx from the Alaskan Beaufort Sea and the Strait of Juan de Fuca. The new species of Chaetozone and Tharyx are compared with related species; distinct species groups within these genera are discussed. A redescription of C. setosa… Expand
Redescription of Tharyx killariensis (Southern) from Ireland and description of two new species of Tharyx from the Kattegat, Sweden (Polychaeta, Cirratulidae).
Two new species of the cirratulid genus Tharyx are reported from shallow waters in the Kattegat inshore Sweden. In addition, the lectotype of Tharyx killariensis (Southern, 1914) is redescribedExpand
The occurrence of two morphologically similar Chaetozone (Annelida: Polychaeta: Cirratulidae) species from the Italian seas: Chaetozone corona Berkeley & Berkeley, 1941 and C. carpenteri McIntosh, 1911
TLDR
The finding of reproducing specimens of C. corona and C. carpenteri supports the hypothesis that these two species have found a suitable habitat in the Western Central Adriatic Sea, and there will become well established, although nothing suggests that C. Corona would be invasive, it may, however, compete with native species. Expand
A new species and four new records of sedentary polychaetes from the Canadian High Arctic
During ArcticNet surveys aboard ‘CCGS Amundsen’ in 2011, several subtidal stations located in Canadian Archipelago were sampled in order to study the composition of their benthic communities. AmongExpand

New species and records of Caulleriella (Annelida, Cirratulidae) from shelf and slope depths of the Western North Atlantic Ocean.
TLDR
Six species of Caulleriella (Cirratulidae), four new to science, are reported from continental shelf and slope depths of the western North Atlantic, as part of deep-water reconnaissance and monitoring surveys intended to understand the potential impacts of oil and gas exploration in poorly known offshore environments. Expand
Species delimitation analyses of NE Atlantic Chaetozone (Annelida, Cirratulidae) reveals hidden diversity among a common and abundant marine annelid.
TLDR
The results reveal several species complexes in the genus Chaetozone, that some of these independent lineages are unnamed and undescribed, and that morphological diagnostic features are in most cases unable to discriminate between the most similar species. Expand
New species of Cirratulidae (Annelida, Polychaeta) from abyssal depths of the Clarion-Clipperton Fracture Zone, North Equatorial Pacific Ocean.
TLDR
Twelve species of Cirratulidae were identified, of which 11 are new to science, and represent a unique assemblage of abyssal taxa that reside in the upper 5 cm of the sediment. Expand
Protocirrineris (Polychaeta:Cirratulidae) in South Africa and description of two new species
TLDR
It is hypothesize that biodiversity of multitentacular Cirratulidae polychaetes has been significantly underestimated in southern Africa and the use of new techniques enables discovery of new taxonomic characters and two new species of the genus Protocirrineris. Expand
