Remarks

Parawaldeckia kidderi ( Smith, 1876) is distributed in the sub-Antarctic islands and the Magellanic area. It was reported by Alonso (1987) for Tierra del Fuego, inhabiting among red algae and less frequently green algae; the present specimens, associated with kelp holdfasts of M. pyrifera , enlarge the distributional area to the Beagle Channel. Arnaud (1974) recognized the species in holdfasts from Kerguelen Islands.
