Description. Macropterous male. Color. Head orange brown, with a small dark brown area below the antenniferous tubercles. Antennae dark brown to black. Eyes dark red. Rostrum brown to dark brown, with the apex of segment III and entire segment IV black. Pronotum orange brown. Fore wings blackish, with well defined whitish pruinose areas between cells, an apical pruinose area shaped as an inverted heart symbol, veins slightly lighter, and a pair of narrow whitish maculae starting from humeri and ending near apex of pronotum ( Fig. 52 View Figs 52–54 ). Pro- and mesopleura orange brown; metapleura orange brown to dark brown ( Fig. 80 View Figs 78–80 ). Prosternum orange brown; meso- and metasternum dark brown. Coxae brown to dark brown; trochanters yellowish to yellowish brown; remaining of leg segments brown to dark brown. Connexiva brown to orange brown. Abdominal segments dark brown to black in spiracle region; sternites brown to dark brown. Genital segments brownish.

Structural characters. Head covered by fine golden pubescence and long dark setae concentrated dorsally. Antenniferous tubercles swollen and shiny. Antennae covered by golden pubescence, with long dark setae scattered on apical region of antennomere II and entire segments of III–IV; antennomere I robust, curved outward; II slightly more robust than III, longer; antennomere IV slightly longer than III, fusiform. Pronotum covered by golden pubescence, long dark setae concentrated laterally on anterior lobe and posteriorly on apical margin, a pair of whitish pruinose areas laterally between anterior and posterior lobes; and another V-shaped pruinose area more evident on posterior lobe, not reaching margins ( Figs 52, 54 View Figs 52–54 ); longitudinal midline weakly carinate, more evident between humeral angles. Pleura with pruinose areas; propleura with a row and other rounded punctations on posterior region; mesopleura anteriorly with a row of some punctations; metapleura with whitish setae posteriorly. Legs covered by golden pubescence, with scattered long dark setae. Protibia slightly flattened distally, with grasping comb approximately on posterior half. Pruinose areas laterally on abdominal segments III–VI, with pruinosity of segments V–VI reaching region above spiracles. Connexiva not elevated, covered by golden pubescence and long dark setae. Body ventrally covered by whitish pubescence. Genital segment I with anterior margin ventrally excavated; posterior region with long dark setae dorsally; dorsal posterior margin slightly concave medially ( Figs 65–67 View Figs 59–70 ). Proctiger without depression, projection or spines ( Fig. 67 View Figs 59–70 ). Paramere elongated, slightly tapering to the rounded apex ( Fig. 76 View Figs 71–77 ).

Macropterous female. Similar in color and morphology to the macropterous male ( Fig. 53 View Figs 52–54 ), except for the more elevated connexiva and pruinose areas on lateral margins of abdominal segments III–VI, the pruinosity of segment III being smaller and in remaining segments reaching region above spiracles.

Intraspecific variation. Some specimens have darker coloration of the pronotum. The basal macula of the fore wing may not be distinct, and the pruinosity on the wing varies slightly in shape and in some cases, the apical pruinose area is not heart-shaped ( Fig. 53 View Figs 52–54 ).

Differential diagnosis. This species is known only in the macropterous form. Its paramere is very similar to O. chenae   sp. nov. in form and arrangement of the setae. However, these species are distinguished in both sexes by the color of the pronotum, uniformly orange to orange brown in O. pydanieli   sp. nov., and orange brown to reddish brown with anterior lobe dark brown in O. chenae   . In addition, male proctiger does not have a slight dorsal depression on the posterior half in O. pydanieli   , which occurs in O. chenae   .

Etymology. Named in honor of Dr. Victor Py-Daniel (Instituto Nacional de Pesquisas da Amazônia, Manaus), in recognition of the significant collection of aquatic Heteroptera   donated by him to the Invertebrates Collection of the INPA.

Distribution and habitat. Brazil (Roraima).

The type series was collected at Serra de Surucucu, in the western part of the State of Roraima, northern Brazil, situated between 800 and 1000 m a.s.l., but without the information about the habitat of the species on the label.
