Naupactus cyphoides is a medium-sized species with very short rostrum and antennae; vestiture is composed of round scales and short recumbent setae, which are confluent along midline of each elytral interval; pronotum is subcylindrical, with bisinuate base; elytra are short with well- developed humeri and flat intervals; denticles of front tibiae are small and corbels of hind tibiae are narrow.

This species shows a remarkable polymorphism in color pattern. Morphotypes or color varieties coexist in some localities of northern Argentina, particularly in Santiago del Estero province. In the typical morphotype and in the griseomaculatus variety sensu Hustache, the vestiture is composed of ash-grey scales and pale brown setae. Scales are absent on center of pronotum and form a mixed pattern of scaly and denuded areas on the elytra.
In prasinus morphotype the color pattern is similar to that of griseomaculatus but scales are iridescent green. In viridinitens morphotype scales are also iridescent green, but they are densely distributed on the dorsal surface. In viridimarginalis morphotype scales are green or cream, and form a stripe along margins of pronotum and elytra; the rest of the integument is mainly covered by pale brown recumbent setae. In viridulus morphotype there is a marginal stripe along margins of pronotum and elytra, and also a stripe along 4º or 4º to 6º intervals of elytra, which in some specimens is not continuous. There are also some specimens intermediate between morphotypes viridulus and viridimarginalis.

Males belong to viridulus morphotype and come from Corrientes (Argentina) and Paraguay. The remaining populations are composed only by females.
Prosopis kutzei Harms Kuntze, Prosopis nigra (Grisebach) Hieron, Medicago sativa L. (Fabaceae), and Schinopsis quebracho-colorado (Griseb.) Engl. (Anarcadiaceae) (Lanteri et al. 2002a).

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