For us falklandellids and paraleptamphopids are both ancient Pangaean families probably near the base of the freshwater amphipod radiation. Both families apparently have gammarid-like calceoli. Falklandellids differ from paraleptamphopids as follows: maxilla inner plate with an oblique setal row (absent in paraleptamphopids); sternal gills present, simple or bifurcate (absent in paraleptamphopids); gnathopod 1 similar in size and form to gnathopod 2 (gnathopod 1 larger than gnathopod
