Remarks: On the basis of the original description and illustrations by Chevreux (1913), the species was provisionally assigned to the genus Fuegiphoxus by Barnard and Barnard (1980). Many features such as setal formulas on articles 4 and 5 of antenna 2, fine details of mouthparts, setal formulas of epimera, lateral and ventral setae of urosomite 1 and setation of uropods require an exhaustive study for confirmation.

Fuegiphoxus? uncinatus was recently recorded in the Magellan area and also extended its distribution in the West Antarctic province since it was recorded in the Drake Passage and Weddell Sea (Rauschert, unpubl.).
