Remarks: Parafoxiphalus Alonso de Pina, 2001 is monotypic, showing many similarities with Foxiphalus Barnard, 1979 such as the general aspect of the body, the unconstricted rostrum and the shape of the appendages; they differ principally in the setal formula on article 4 of antenna 2, in the number of calceoli on article 5 of male antenna 2, in the shape of gnathopods 1 and 2 and in the setation of peraeopods 3 and 4, epimera 1 and 2, and uropods 1 and 2.

Parafoxiphalus longicarpus extends its distribution in the Magellan area from Chubut province (Alonso de Pina, 2001) to southern Tierra del Fuego in Argentina (Chiesa et al., 2005).
