Remarks.

The new species, O. omanensis , closely resembles O. circularicollis Werner & Peters, O. formosa (Giraud), and O. niehuisorum Werner & Peters, but differs from them in the following:

O. omanensis vs. O. circularicollis (Morocco). Eye large, 0.70−0.75 × as high as head (small, 0.54 –0.56× as high as head, in circularicollis ); POL 1.4 × OOL (as long as OOL in circularicollis ); pronotum as long as wide, with anterior margin (collar) truncate (0.91 × as long as wide, with collar virtually round in circularicollis ); mesoscutellum almost completely lineate, finely areolate slightly before frenal line (lineate in anterior two-thirds, rugulose in posterior third in circularicollis ); marginal vein 4 × as long as stigmal vein (2.5- 3.53 × as long as stigmal vein in circularicollis ).

O. omanensis vs. O. formosa (Southern and Central Europe, Russia, Eastern United States, Eastern Canada). Head and mesosoma blue and purplish (dark green and coppery in formosa ); scape of antenna red-brown, with black tint apically (yellow, darkening apically in formosa ); head width 4.5 × eye distance (3.00 –3.78× eye distance in formosa ); eye 0.75 × as height as head (0.55−0.68 × as height as head in formosa ); corona with structure interrupted (with structure continuous in formosa ); pronotum with broadest part behind midlength (with broadest part at midlength in formosa ); mesoscutellum almost completely lineate, finely areolate slightly before frenal line (lineate in anterior half to anterior two-thirds, rugulose in posterior half or third in formosa ); profemur robust to medium, 1.92 –2.00× as long as wide (usually medium to elongated, 1.94 –2.33× as long as wide, in formosa ).

O. omanensis vs. O. niehuisorum (Egypt and Israel). Forewing partly slightly infumate (hyaline in niehuisorum ); corona thick, 3.33−3.50 × as long as wide, with structure interrupted (usually medium, 3.8 –6.0× as long as wide, with structure continuous in niehuisorum ); pronotum with broadest part behind midlength (broadest part before midlength in niehuisorum ); mesoscutellum almost completely lineate, finely areolate slightly before frenal line (densely lineate in anterior half to anterior two-thirds, areolate in posterior half or third in niehuisorum ); marginal vein medium, 0.92−1.00 × as long as postmarginal vein (short, 0.78 –0.89× as long as postmarginal vein in niehuisorum ).

O. omanensis sp. nov. also resembles the new species O. similis , but differs from it in the following combination of characters: forewing partly infumate, with dark brown to black veins (hyaline in O. similis , with pale brown veins); head with bluish to purplish luster (green and coppery in O. similis ); mesoscutellum with green basal half, violet posteriorly (entirely green in O. similis ); pronotum distinctly narrow anteriorly, with dense lanceolate whitish setae longitudinally along the middle area, with broadest part behind midlength (distinctly broad anteriorly, with fewer setae along the middle area longitudinally, with broadest part before midlength in O. similis ); propodeum medium, ppd.l/msc.l 0.13-15 (large, ppd.l/msc.l 0.17−0.21, in O. similis ); volsella of male genitalia with four sharp teeth, aedeagus with parallel outer sides (with five teeth, aedeagus with strongly convex outer margins in O. similis ).

Etymology.

Named in reference to the country of Oman, where the type specimen was collected.
