In Antarctic and sub-Antarctic seas, the genus Liljeborgia has been recorded from 4 to 4385 m. The occurrence of 12 valid previously named species is conrmed south of 40°S (Tasmania and New Zealand excluded): L. chevreuxi SCHELLENBERG, 1931, L. consanguinea STEBBING, 1888, L. eurycradus THURSTON, 1974, L. georgiana SCHELLENBERG, 1931, L. georgiensis K.H. BARNARD, 1932, L. kerguelensis BELLAN-SANTINI & LEDOYER, 1974, L. longicornis (SCHELLENBERG, 1931), L. macrodon SCHELLENBERG, 1931, L. octodentata SCHELLENBERG, 1931, L. pseudomacronyx BELLAN-SANTINI & LEDOYER, 1987, L. quadridentata SCHELLENBERG, 1931 and L. quinquendentata SCHELLENBERG, 1931. All these species are re-described in detail, wherever possible after the types. In addition, 11 new Antarctic and sub-Antarctic species (6 shelf and 5 deep-sea species) are described: L. abyssotypica n. sp., L. bythiana n. sp., L. cnephatis n. sp., L. cryptothrix n. sp., L. homospora n. sp., L. nesiotica n. sp., L. permacra n. sp., L. polydeuces n. sp., L. prionota n. sp., L. rauscherti n. sp. and L. semperhiemalis n. sp. Two additional species (Liljeborgia sp. 1 and sp. 2) are characterized but not named, due to the inadequate condition of the available material. It is demonstrated that L. falklandica K.H. BARNARD, 1932 is a junior synonym of L. octodentata SCHELLENBERG, 1931. The Antarctic and sub-Antarctic records of L. dubia (HASWELL, 1879), and the sub-Antarctic record of L. proxima CHEVREUX, 1907 are not accepted because the types of these species originate respectively from warm-temperate and tropical seas, and such species from warmer climates are unlikely to occur in the frigid waters of the Southern Ocean. Several species have a very restricted distribution (e.g. insular endemism) and such species are probably very vulnerable to major environmental alterations. All Antarctic and sub-Antarctic Liljeborgia can be divided into two morphologically homogeneous groups of species: a group without setae on the outer distal border of the rst article of the palp of the maxilliped and with only one (distal) spine on the dorsomedial border of the peduncle of the rst uropod, and a group with dorsal setae on the outer distal border of the rst article of the palp of the maxilliped and with several spines on the dorsomedial border of the peduncle of the rst uropod. These two groups, which are also characterized by other less constant characters, appear widely distributed across the world oceans.
