Diagnostic characters. Head and pronotum reddish brown, except for the orange margins of the posterior lobe of pronotum. A pair of small areas of whitish pruinosity laterally on the anterior lobe and another more evident V-shaped area on the posterior lobe. Fore wings reaching the genital segments, with a faint uniform whitish pruinosity covering almost the entire wing and a pair of elongated pale yellow maculae at the base, starting from humeri and surpassing the apex of pronotum ( Figs 29–31 View Figs 29–31 ). Coxae and trochanters yellowish; femora and tibiae dark brown to black. Proctiger of the male without elevation or spines ( Fig. 43 View Figs 35–46 ). Paramere narrow medially, widening distinctly in posterior half of the dorsal surface, with subtruncate apex ( Fig. 73 View Figs 71–77 ).

Differential diagnosis. This species is known only in the macropterous form and is morphologically similar to O. cunucunumana   ; both species were collected in the same mass of foam. However, O. rivicola   has a V-shaped pruinose area on posterior lobe of pronotum and posterior half of the paramere distinctly widened, subtruncate, whereas in O. cunucunumana   the pruinosity is absent and the paramere is not distinctly widened posteriorly, having more setae along its margins. Also, both sexes are differentiated by the length of the antennomere IV, smaller (0.33–0.37 mm) and wider in O. cunucunumana   , and longer (0.42–0.48 mm) and slender in O. rivicola   . It differs from the others species which also have a V-shaped pruinosity on the posterior lobe of pronotum ( Oiovelia chenae   sp. nov., O. hamadae   sp. nov. and O. pydanieli   sp. nov.) in the fore wings without well-defined pruinose areas between the cells, which occur on the other three species.

Distribution and habitat. Venezuela ( SPANGLER 1986) and Brazil: Amapá and Amazonas (present study). The first record for Brazil.

SPANGLER (1986) mentioned that all specimens examined in his study were collected by an ultraviolet light trap on the banks of the Baria river in a non-elevated region (140 m a.s.l.) in southern Venezuela. The author also assumed that its habitat would be possibly streams. Recently, specimens of O. rivicola   were collected in foam masses formed in black water streams, both on the surface and in galleries formed within these.
