Ecology: Collected from mud, sandy bottoms with shells, gravel, algae.

Type material location: NRS, Stockholm.

Remarks: Proharpinia stephenseni and P. antipoda can be distinguished from each other by the shape of epimeron 3, the basis of peraeopod 7, the apices of telson, the size of eyes, and the setation of uropods 1 and 2.

The species expands its distribution in southern Tierra del Fuego (Chiesa et al., 2005) and southern Chile (Rauschert, unpubl.). Alonso de Pina (unpubl.) extends this geographical range of distributions northern, for the first time in Chubut province.
