): pronotal pubescence medially absent (densely covering the entire surface in
O fuscus
); short elytral pubescence (long elytral pubescence in
O. fuscus
); major male frontal carina completely impressed (not impressed laterally in
O. fuscus
); major male pronotal prominence obtusely trapezoidal (obtusely triangular in
O. fuscus
); female frontal carina complete, rounded (not impressed laterally, trapezoidal in
O. fuscus
); apical-superior area of the parameres trapezoidal (obtuse in
O. fuscus
); apex of the inferior right lobe concave (claw shaped in
