Abstract

Two new species of the genus Polybrachia Ivanov, Polybrachia macrolamellosa sp. n. and P. romanovi sp. n., found at two stations in the Atlantic sector of the Antarctic Ocean on cruises 11 and 43 of the R/V Akademik Kurchatov (1971 and 1985–1986) are described. The material was collected in the Scotia Sea (off northern Elephant Isle, at a depth of 3110 m) and in the South Sandwich Trench (8004–8116 m). The main distinctive features of the new species are the extremely large cuticular plaque (up to 88 µm in maximum diameter) on the trunk metameric papillae in P. macrolamellosa sp. n. and the very long cephalic lobe (Lcl/Df is about 2) in P. romanovi sp. n.
