Type Material. Lectotype male deposited at Naturhistoriska Riksmuseet, Stockholm Sweden (NHRS), examined .

Description. Small to medium size (Table 1). Color pale orange to dark reddish-ferrugineous (Fig. 2);

antennal segments I-III orange, IV-Vlight ferrugineous; legs orange to yellowish. Punctures denser on median third of abdomen, less dense on lateral thirds of abdomen and on dorsal surface of body. Clypeus slightly longer than mandibular plates (Fig. 31). Bucculae subtruncate posteriorly. Antennal segment Inot attaining apex of mandibular plates; segment Vtwice the length of IV. Proportion of antennal segments: I <II <III ≈ IV <V. Anterior anglesof pronotum with small acute projection (Figs. 2 and 31). Anterolateral margins of pronotum slightly convex, emarginated. Scutellum tapering toward apex attaining at least level of anterior half of connexivum of segment V, sometimes posteriorhalf of segment V; discof scutellum not elevated (Fig. 2).

Male Genitalia. Pygophore subquadrangular (Figs. 38 and 40); dorsal rim sinuous shallowly concave over segment X (Figs. 39 and 48, 54); ventral rim excavated in a deep “V” (Figs. 38 and 40, 55-56); inferior layer of ventral rim projecting ventrally in a small tubercle well visible in posterior view (Fig. 48); posterolateral angles of pygophorerounded (Fig. 6B); ventral wallof pygophore with rounded depression on either side, not attaining posterior margins of pygophore; posterior third of segment X with 1 + 1 slightly elevated rounded areas (Figs. 48 and 55).

Female Genitalia. (Fig. 64). Posterior margin of gonocoxite 8 sinuous; sutural angles conspicuously elevated, strongly projecting posteriorly over gonocoxite 9 and almost completely covering these plates; sutural marginsoverlapping at basal thirdand parallel at apical two-thirds. Posterior margin of laterotergite 8 uniformly convex; laterotergite 9 enlarged at base, tapering toward apex, somewhat inflated, slightly surpassing the band uniting laterotergite 8 dorsally.

Distribution. Neotropical Region provinces (Fig. 69): Pampa (Chacoan subregion), Araucaria angustifolia Forest, and Parana Forest (Parana subregion). Andean Region provinces: Valdivian Forest and Magellanic Forest (Subantarctic subregion), Central Patagonia and Subandean Patagonia (Patagonian subregion).

Comments. O. punctaria shareswith O. ventanensis the clypeus longer than the mandibular plates; with O. flonensis and O. ventanensis the acute projection at the anterior angles of the pronotum; with O. pallidula the disc of the scutellum not elevated; and with O. unidentata and O. pallidula the anterolateral margins of pronotum slightly convex. The scutellum tapering toward apex, the laterotergite 9 somewhat inflated, slightly surpassing the band uniting the laterotergite 8 dorsally, and the ventral rim of pygophore excavated in a shallow “V” are unique characters of O. punctaria .
