Nueva distribución de Paralomis birsteini Macpherson, 1988 en aguas antárticas (Anomura, Lithodidae, Lithodinae)

Abstract

Eighty-eight specimens of Paralomis birsteini Macpherson, 1988, were caught with traps over the submarine Gerlache sea mounts and surroundings Pedro I Island, in the Bellingshausen Sea; over the continental slope to the west of the Antarctic Peninsula and in the Scottish Sea (Statistical Subareas 88.3, 48.1 and 48.2), between 621 and 1876 m depth. Measurements of the cephalothoraxic length of specimens were between 50.8 and 110.2 mm, and 249-g weight on the average. Yields relative to the total traps used in each subarea, were 87.3 g/trap in Subarea 88.3; 2.2 g/trap in Subarea 48.1; and, 548.8 g/trap in Subarea 48.2. The presence of the family Lithodidae in the Southern Ocean is discussed.
