Lissarca bennetti Preston, 1916: 271 View in CoL , pl. 13, figs 7, 7a

Material examined. • 50 spms, Stn. 4.

Type locality. Bransfield Straits near South Shetland Islands at a depth of 27 m (from a fish stomach).

Bathymetric distribution. 0–30 m.

Substrate. Epibenthic, attached by byssus to hard substrates, algae or hydroids and bryozoans.

Geographical distribution. ANTARCTICA: Antarctic Peninsula. SUBANTARCTICA: -. SCOTIA ARC: South Georgia, South Orkney Islands, South Shetland Islands. SOUTH AMERICA: -.

Remarks. Until recently, the name L. miliaris (R. A. Philippi, 1845) was used for the findings at King George Island. Güller & Zelaya (2025) revised the species complex morphologically and genetically and have re-established L. bennetti for the Scotia Arc islands and the Antarctic Peninsula while L. miliaris is restricted to the Magellan region. We have observed this species only at one intertidal station with about 50 specimens. The species is already known from the Maxwell and Admiralty Bays. For Antarctic Peninsula beds it is one of the most common epibenthic species on the red algae Gigartina ( Rosenfeld et al. 2017) .
