“Lissarca miliaris (Philippi, 1845) (Figs 53-54)

Pectunculus miliaris Philippi, 1845: 56.

Lissarca bennetti Preston, 1916: 271, figs 7, 7A.

Lissarca miliaris: Dell, 1964c: 172 (synonymy); Nicol 1966: 39, pl. 1, figs 4, 9: Richardson, 1980: 91 (ecology and reproduction).

MATERIAL EXAMINED: Eltanin Stns 217, 377, 450, 958, 969, 974, 980, 981; Hero Stns 219, 450, 489, 656; Oregon State University Stn AH4-30; Vema Stn V-15-112; Swedish South Polar Expedition Stn 64; Cumberland Bay, South Georgia, 9 May 1902; Eldslanst Expedition, 1896, three stations off Tierra Del Fuego, 18-183 m; St Nicholas Bay, Magellan Strait, 11-17 m, Eugénie Expedition, 4 Feb 1852; Port Famine, Magellan Strait, Eugénie Expedition, 1 Feb 1852.

DISTRIBUTION: Lissarca miliaris can now be confidently recorded from the Magellanic region, South Georgia, South Orkneys, South Shetlands and the Antarctic Peninsula in depths of 0-265 m (with one anomalous record from Eltanin Stn 377 (1878-1886 m), based on a single specimen).

REMARKS: This species also broods its young. The distinction between L. rubrofusca (Smith, 1877) and L. miliaris (Philippi, 1845) has been confused, and L. rubrofuscata has been recorded from the islands of the Scotia Arc by Martens (1885), Martens and Pfeffer (1886) and Melvill and Standen (1907). All the collections from the Magellanic region (except for that discussed later from Eltanin Stn 740), South Georgia, the South Orkneys, South Shetlands and the Antarctic Peninsula studied by the writer represent the one species and this should bear the earlier name applied to this species of Lissarca, i.e. miliaris Philippi.”
