Pantomorus viridisquamosus species group includes a species with the same name and P. obrieni, and it was revised by Lanteri & Loiácono (1990).
The vestiture is iridescent green, same as P. auripes, but the scales are less dense and the elytral setae are short and recumbent; the pronotum has almost straight flanks, slightly divergent towards base; and elytra are less convex than in this species.
First instar larvae and postures of P. viridisquamosus have been described by Loiácono & Díaz (1995). Males are absent or scarce in most populations. Females probable reproduce by parthenogenesis (Lanteri & Loiácono 1990, Lanteri & Normark 1995) and are infected with the bacterium Wolbachia which induces this kind of reproduction in several species of Naupactini (Rodriguero et al. 2010a).
A niche modeling analysis suggests that southern USA, close to the coast of the Gulf of Mexico, is suitable for the occurrence of this species (Lanteri et al. 2013b).
Medicago sativa L., Glycine max (L.) Merr. and Lotus sp (Fabaceae) in Argentina, Uruguay and southern Brazil (Alzugaray et al. 1998, Lanteri 1994, Lanteri et al. 2002a, Lanteri et al. 2013a).
Mainly associated with native vegetation of the Espinal and Pampean biogeographic province.
