Remarks. Ponder (1983) distinguished two subspecies, E. k. kerguelensis (E.A. Smith, 1875) and E. k. regularis (E. A. Smith, 1915). The first, somewhat smaller subspecies (up to 3 mm) is restricted to the Kerguelen Islands. The second (up to 4.5 mm) is occurring around the Antarctic continent and the islands of Scotia Arc (see also Engel 2012). Since we do not differentiate at the subspecies level in this paper and also have too little material available to provide clarity in this regard, we will refer only to E. kerguelensis . If only the size is taken into account (our material was 3 to 4 mm high) then E. kerguelensis regularis can be assumed. The depth covered was intertidal up to 100 m. The species is already known from Maxwell and Admiralty Bays.
