Naupactus versatilis is distinguished because the vestiture is iridescent green or copper-colored, moderately dense and almost uniform (they do not form stripes), composed by oval to lanceolate scales; scutellum is whitish or cream same as venter. There are minute recumbent pale setae mix with scales on the whole integument and elytral apex bears fine, long, erect setae.
Antennae are fine, moderately long; pronotum is subconical with curved flanks and almost straight base; elytra are oval, convex, with slightly bisinuate and not thickened base, striae are distinct and intervals are flat, with very slight transversal rugosities; integument of legs is dark; front tibiae have small denticles on inner margin; corbels of hind tibiae are absent.

This species mainly differentiates from N. auricintus because pronotum is wider and more convex; elytra are shorter, with more reduced humeri, less rugose intervals, and more acute apex. Vestiture is almost uniform, without a pattern of light stripes on the elytra.

Males are more slender than females and scarce in populations.

Guedes & Parra (2004) studied the oviposition habits of this species.
Species harmful for Citrus sp (Rutaceae) in Brazil, São Paulo and Minas Gerais states (Lanteri et al. 2002b, Guedes et al. 2005).

It is mainly associated with vegetation of the Paranaense and Chacoan biogeographic provinces.
