Remarks: Barnard and Barnard (1980), who revised extensively Parharpinia fuegiensis Schellenberg, 1931 from the NRS, Stockholm collections, noticed that the specimens were mixed with two other undescribed species. They erected the genus Fuegiphoxus based on some morphological characters related to antenna 2, mouthparts, gnathopods, peraeopods and uropods; thus, they redescribed F. fuegiensis and described the new taxa F. abjectus and F. inutilus . These species can basically be separated from each other by the combination of some features such as setal formula on peduncle article 4 and the number of robust setae on article 5 antenna 2; setation of propodus peraeopods 3 and 4; shape of epimera, and length of uropod 3. Fuegiphoxus abjectus also is characterized by an atypical antenna 1 in males, very stout. Fuegiphoxus inutilus shows the epimera 1 and 2 with posteroventral tooth, a character not found in the other species mentioned above.

Fuegiphoxus fuegiensis extends its range of distribution in the Magellan area along the Argentinean littoral (Chiesa et al., 2005; Alonso de Pina, unpubl.) as well as in the Chilean side (Rauschert, unpubl.). It was also recorded for the first time in the Drake Passage (Rauschert, unpubl.) and it is a new record for the South Shetland Islands (Alonso de Pina, unpubl.).

Geographical information about the species mentioned above was provided by the NRS, Stockholm. Syntype No. 811 was identified as Parharpinia fuegiensis from Chile, Valparaiso, but according to JLB 60 and B&B 80, the specimens from this locality belonged to Phoxorgia sinuata .
