Naupactus navicularis is similar and phylogenetically close to N. xanthographus (Lanteri & del Río 2017; Scataglini et al. 2005). It mainly differentiates because the vestiture is pinkish-brown, with pale stripes along pronotum and elytra (instead of grey-brown with yellow and/or white stripes); the sides of the pronotum are more straight and slightly divergent towards base; elytra are more flat, striae have large punctures and the apical tubercles are small to vestigial; hind tibiae of males do not have denticle on inner margin.
Males are more slender than females and are usually less frequent than females.

Harmful for Citrus spp in Brazil (São Paulo and Minas Gerais), especially orange (Lanteri et al. 2002b, Guedes et al. 2005).

It is mainly associated with vegetation typical of the Atlantic and Paranaense forests.
