Remarks
This is one of larger species of Primno, attaining lengths of up to 15 mm. It is very similar to P. abyssalis which, until relatively recently (Bowman 1985), was considered a synonym. Although Bowman (1978) presumed the type of P. macropa was lost, his studies of this species are confirmed by the examination of the type, which probably came from the subantarctic waters off Chile. The distribution of this species is restricted to the subantarctic biotic province.
