It shows extensive variation in patterns of dorsal coloration and in morphology.

[3] Pseudopaludicola falcipes shows a high level of genetic diversity but, contrary to what might expected for a small frog, no significant differentiation across its distribution range.

This situation is probably possible because of the homogeneity of its habitat, the Pampean grasslands, large population sizes, and passive mechanisms of dispersal (hydrochory).

Molecular data nevertheless suggest that Pseudopaludicola falcipes is divided into two populations, the larger one in Argentina and Uruguay, and the smaller one in Brazil.

It adapts well to disturbed habitats and, given its wide distribution, is not considered threatened.
