Abstract

Three new species of the scalibregmatid genus Oligobregma Kudenov & Blake, 1978 are described from Antarctic waters. The species are best distinguished by the number and arrangement of acicular spines in anterior notopodia. While Oligobregma pseudocollare sp. nov., bears two rows of spines in the first two notopodia, spines are arranged in single rows in Oligobregma blakei sp. nov. In Oligobregma quadrispinosa sp. nov., the first four chaetigers are armed with acicular spines. The species were collected from depths between 753 and 4069 m in the Scotia and Weddell Seas. A comparison with further species of Oligobregma known from Southern Oceans is given.
