E. unicolor differentiates from all the remaining species of Eurymetopus because is larger, with greyish scaly vestiture and almost indistinct dark-brown maculae on the elytra; the forehead is very broad, the eyes very convex and the pronotum shows large punctures. It was redescribed by Lanteri & Morrone (1995), which provided a key for the seven species of the genus.

This species is flightless and probably parthenogenetic, based on the absence of males (Lanteri & Normark 1995).

It is associated with gramineous plants of the Pampean biogeographic province.
