Material examined

GALICIA BANK • 3 v; 42°37.77′ N, 11°49.46′ W; 818 m; 30 Jul. 2011; BANGAL 0711 V3; MNCN • 4 v; 42°41.94′ N, 11°40.58′ W; 744 m; 31 Jul. 2011; BANGAL 0711 V4; MNCN .

Remarks

A specimen of this species from GB was figured by Rolán et al. (1990) as Cuspidaria capensis (E.A. Smith, 1885) . Specimens from GB have a posterior rostrum shorter than usually seen in Cuspidaria rostrata , and are smaller, resembling in those features Cuspidaria meteoris Krylova, 2006 , described from the mid-Atlantic seamount group. However, they do not show the sloping postero-ventral margin characteristic of the latter, and are therefore conservatively identified to the mainland species.
