Naupactus tarsalis is similar to N. schapleri in body size, shape and color pattern, and mainly differentiates because has more convex eyes and more elongate elytra.
Antennae are slender and long, pronotum is truncate-conical, with slightly punctate disc, curved flanks, and bisinuate beveled base; elytra are elongate and slender, with strongly bisinuate and thickened base, broad humeri, flat intervals and distinct punctures of striae; denticles on inner margin of front tibiae are small and corbels of hind tibiae are slender, squamose.

This species shows two morphotypes, the typical one is almost completely nude of scales, except for a pair of wide, yellow (type of N. tarsalis) or green (type of N. glaucivittatus) stripes, along margins of pronotum and 5° to 7° intervals of elytra. In the squamose morphotype (type of N. albidiventris) the stripes are cream and usually divided in three parts along the elytra; the rest of the integument is covered with loose whitish seta-like scales. In both morphotypes the scutellum is covered with white scales.
Males are more slender than females and tarsi of the front legs are widened.

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

Mainly associated with vegetation of Cerrado and Chacoan biogeographic provinces.
