E. fallax is the type species of Eurymetopus, revised by Lanteri (1984). It differentiates from E. birabeni mainly because the elytra are more slender, with reduced humeri and a single pair of dark-brown maculae on center. The general color pattern is greyish-brown.
This species is flightless, probably parthenogenetic (Lanteri & Normark 1995) and females are infected with the bacterium Wolbachia (Rodriguero et al. 2010a).
A niche modeling analysis suggests that southeastern USA, France and eastern Australia are suitable for the establishment of E. fallax (Lanteri et al. 2013b).

Medicago sativa L. and Lotus (Fabaceae), Helianthus annuus, Triticum aestivum L., other cereals (Poaceae) and Eucalyptus sp (Myrtaceae) (Alzugaray et al. 1998, Lanteri 1994, Lanteri et al. 2002a).
It is associated with native vegetation and crops of the Pampean biogeographic province.
