Diagnostic characters. Head dark brown to black, except for orange brown posterior region and inner margin of the eyes. Pronotum orange brown, with only a pair of small lateral whitish pruinose areas between the anterior and posterior lobes. Fore wings reaching the genital segments dark brown, with a pair of whitish to yellow elongated maculae at the base, starting from humeri and surpassing the apex of pronotum; entirely covered by a faint uniform whitish pruinosity, which can be absent below the basal maculae ( Fig. 28 ). Coxae and trochanters yellowish; femora and tibiae dark brown to black. Proctiger of male without elevation or spines ( Fig. 40 ); paramere tapering slightly in middle, with rounded apex and setae on the dorsal and ventral surfaces ( Fig. 72 ).

Intraspecific variation. Within the same population, the color of head and pronotum varied significantly from orange brown, typical of this species, to dark brown ( Figs 26–27 ). In some cases the difference of color dorsally on the head is not evident.

Differential diagnosis. This species is known only in the macropterous form and has O. rivicola as a morphologically similar species. Both are distinguished by the V-shaped pruinosity on the posterior lobe of pronotum, which is absent in O. cunucunumana and present in O. rivicola , and by the shape of paramere, widening distinctly in the posterior half of the dorsal surface with subtruncate apex in O. rivicola , whereas in O. cunucunumana it is not distinctly wide on dorsal surface, with rounded apex. Also, both sexes of the species are differentiated by the length and shape of the antennomere IV, smaller (0.33–0.37 mm) and wider in O. cunucunumana ( Figs 26–28 ), and longer (0.42–0.48 mm) and more slender in O. rivicola ( Figs 29–31 ).

Distribution and habitat. Venezuela (DRAKE & MALDONADO- CAPRILES 1952, DRAKE & ROZE 1955), Brazil [Amapá ( RODRIGUES et al. 2012), Amazonas ( RODRIGUES et al. 2012), Pará (present study), Minas Gerais ( RODRIGUES et al. 2012), São Paulo (MOREIRA & BARBOSA 2011; present study) and Santa Catarina ( SPANGLER 1986)], Peru ( SPANGLER 1986), Paraguay ( DRAKE & ROZE 1955) and Argentina ( MAZZUCCONI & BACHMANN 1997a).

At the moment, O. cunucunumana is the species of the genus that has the largest occurrence area, recorded from Venezuela to Argentina. In collections recently made in the state of Amazonas, northern Brazil, it was frequently collected together with O. rivicola in the same foam masses.
