Title

A new species the genus Chaetozone (Annelida: Cirratulidae) from the seaward part of Chaunskaya Bay in the East Siberian Sea (Russia)

Abstract

Based on material collected by the author over several years and seasons in Chaunskaya Bay of the East Siberian Sea, a new species, Chaetozone buzhinskajae sp. nov., is described. Morphologically, it is most similar to Ch. setosa Malmgren, 1867 and Ch. pugettensis Blake, 2015, which belong to a group of species characterised by an enlarged lobe or crest covering the peristomium. The new species is dis?tinguished by the presence of neuropodial spines in the anterior part of the last third of the body (from the 48th to the 72nd setigerous segment), a complete achaetous segment that is well separated from the peristomium and setiger 1, and a distinctive methylene green staining pattern. Specimens were collected at depths ranging from 12 to 50 m in the seaward part of the bay.

На основе материалов, собранных автором в различные годы и сезоны в Чаунской губе Восточно-Сибирского моря, описан вид Chaetozone buzhinskajae sp. nov. Морфологически новый вид наиболее близок к Ch. setosa Malmgren, 1867 и Ch. pugettensis Blake, 2015, принадлежащих к группе видов с увеличенной лопастью или гребнем, покрывающим перистомиум. Новый вид характеризуется наличием невроподиальных ацикуловидных щетинок в последней трети тела (с 48 по 72 щетинковый сегмент), наличием хорошо развитого бесщетинкового сегмента тела, полностью отделенного от перистомиума и первого щетинкового сегмента тела, и характерной окраской метиленовым зеленым.
