Loc. Typ.: Madagascar.
Material examined. MADAGASCAR: Perinet, 12.10.1970 [-18.924381, 48.417825] (1 ♁, 1 ♀, BMNH) GoogleMaps ; Andapa, 12.1948, Capuron leg.

Basilewsky 1948” (1 ♀, ISNB) ; Andranomandevy, Didy, 1039 m, Ambatondrazaka, X.1956 [-18.156420, 48.622997] (2 ♁, 2 ♀, MRAC) GoogleMaps .
Differential diagnosis. Similar to O. amandae but differ in having less rounded elytra, 14 elytral striae ( Fig. 52 View FIGURES 52–53 ), more rounded and prominent hind angles of pronotum, and different endophallus structure ( Figs. 72–73 View FIGURES 72–75 )
Redescription: Body length 5.0– 5.4 mm; width 3.34–3.37 mm. Habitus ( Fig. 52 View FIGURES 52–53 ).
Color: head, pronotum and elytra rufopiceous. Pattern of head, pronotum, and elytra black or expressly dark green. Legs and antennae brown. Mandibles rufopiceous. Venter, excluding epipleura, dark reddish brown. Proepipleura and elytral epipleura brown.
Head moderately flat, coarsely punctate laterally and posteriorly, sparsely punctate around clypeus and on the middle of the frons, with punctures deep and distinctly margined. Surface around eyes weakly wrinkled. Pale pattern on head V-shaped, with indistinct boundaries. Clypeus faintly convex, bisetose. Front margin of clypeus formed by two straight lines meeting at an obtuse angle. Labrum slightly emarginate, with six setae. Subocular ridge well developed and sinuate. Antennal scape unisetose at apex, antennomeres 3 and 4 smooth, with some longer setae around the apex, 5–11 pubescent. Gula smooth, gena with only a few coarse punctures. HW: 1.62–1.64 mm.
Pronotum (PL: 1.35–1.38 mm, PW: 2.81–2.86 mm.) moderately convex, base bisinuate, sides slightly rounded, hind angles almost acute. Pronotum coarsely and densely punctate, pronotal margin with a few coarse punctures. Median line shallow and faint. Prosternum and proepisternum coarsely and irregularly punctate, with punctures deep and broad.
.
Elytra (EL: 3.42–3.48 mm., EW: 3.51–3.55mm) weakly convex, elongate, sides moderately rounded on shoulders and near the apex, with relatively wide border. Elytra with 14 striae, extended from the base to more than two thirds of the elytral length, in the apical third they become less deep and less punctate. Striae deep, punctures clearly marked. Intervals weakly convex on disc, moderately convex on sides.
Venter ( Fig. 54 View FIGURES 54–56 ). Metasternum, metepimeron and metepisternum coarsely and irregularly punctate. Abdominal ventrites smooth medially, weakly wrinkled and punctate laterally; ventrites IV and V with one pair of paramedial setae. Metacoxae bisetose, with a few weak punctures.
Aedeagus ( Fig. 57 View FIGURES 57–58 ). Endophallus with large patch of relatively long spines ( Fig. 72 View FIGURES 72–75 ).
Distribution: Madagascar.
