Naupactus bridgesii is a large species, covered with small iridescent green or cream scales and short recumbent setae. Vestiture is dense along midline and sides of pronotum and elytra, and is absent along suture, anterior third of 3° interval and whole 7° interval of elytra; scutellum is covered with white scales.
Antennae are broad; pronotum is truncate-conical, with strongly curved flanks, convex disc, deep midline sulcus, and bisinuate beveled base; elytra have bisinuate base, broad humeri, and uneven intervals 3° and 7° more convex the even intervals; front tibiae bear medium-sized denticles on inner margin and corbels of hind tibiae are broad, squamose.

This species is similar to N. argentinensis in size and body shape, but the pronotum and the elytra are more slender and the vestiture is more colorful and does not cover the whole dorsal surface.
Naupactus bridgesii causes damage to Gossypium hirsutum L. (Malvaceae) and Medicago sativa L. (Fabaceae) in Argentina (Lanteri et al. 2002a).

It is associated with native vegetation of the Chacoan and Monte biogeographic provinces.
