Diagnostic characters. Color of head and pronotum dark reddish brown to reddish brown. Body and legs covered by long dark setae. Coxae, trochanters and femora light brown to yellowish, with remaining segments of the legs brown to dark brown ( Fig. 25 View Figs 22–25 ). Fore wings in macropterous form reaching the genital segments, dark brown, with the veins slightly lighter, and a pair of pale yellowish maculae at the base, starting from humeri and surpassing the apex of pronotum; entirely covered by whitish pruinosity, more evident between the cells ( Fig. 24 View Figs 22–25 ). Proctiger of the male with a pair of small spines on half of the dorsal surface ( Fig. 37 View Figs 35–46 ). Paramere with ventral surface widening in the posterior half ( Fig. 71 View Figs 71–77 ). Female abdomen with a slight lateral constriction on segments III–IV ( Fig. 25 View Figs 22–25 ).

Intraspecific variation. We observed substantial variation in color and pilosity. Some specimens have the tegument of the body and legs orange brown to yellowish brown. We examined an apterous male (in MZSP) that had few setae along the margins of the body, possibly lost over the time. Also the spines of the male proctiger varied slightly in size.

Differential diagnosis. This species is known from apterous and macropterous form, and has O. viannai sp. nov. as a morphologically similar species. It differs from the later in the body color, ranging from brownish to reddish brown, presence of a pair of spines on male proctiger, and abdominal segment III–IV of the female slightly constricted, whereas in O. viannai the body is dark brown to blackish and spines on male proctiger and constriction on female abdomen are absent.

Distribution and habitat. Brazil: Minas Gerais ( RODRIGUES et al. 2012; present study), border of Minas Gerais and Rio de Janeiro (MOREIRA & BARBOSA 2012), Espírito Santo ( MOREIRA et al. 2010), São Paulo (MOREIRA & BARBOSA 2011; present study), Rio de Janeiro (MOREIRA et al. 2012) and Rio Grande do Sul ( MOREIRA & CAMPOS 2012).

This species was described from the state of Espírito Santo, southeastern Brazil, and later recorded in other four states of Brazil. Generally, it is collected in small numbers of specimens and may or may not be found on foam masses.
