( Figs. 5, 6 View FIGURES 1–8 , 11, 12 View FIGURES 9–16 , 23–25 View FIGURES 17–31 )

Diagnosis. This species resembles O. diamantina sp. nov. from which it can be distinguished by the apex of distiphallus composed of a dorsal tube not conical with a pair of sclerotized flaps at its lateral base, apex of ventral tubes with flap-like lateral expansion, and apex of distiphallus about 0.90x of cercus length. Due to its similarity to O. dimanatina , only the features that distinguish it from the latter will be described below.

Description. Male. Body length: 9.23 mm; wing length 8.0 mm.

Vertex about 0.25x head width in dorsal view; outer vertical setae about 0.57x length of inner vertical setae; pedicel about 0.45x length of postpedicel; scape about 0.49x length of pedicel; lateral of thorax brown slightly orange; legs brown; abdomen, in ventral view, with syntergite 1+2, tergite 3 and 4 brown slightly orange, and tergite 5 slightly more orange.

Terminalia of O. mineira sp. nov. ( Figs. 23–25 View FIGURES 17–31 ) differ from those of O. diamantina sp. nov. by the segment 7 + 8 about 3.0x length of anterodorsal margin of epandrium, apex of distiphallus with the dorsal tube not conical, flap-shaped structure (lost in dissection) at the base of the dorsal tube longer, presence of a pair of sclerotized flaps at the lateral base of the dorsal tube, microspines of the distiphallus more conspicuous, apex of the ventral tubes flap-shaped, and apex of the distiphallus about 0.90x of cercus length.

Female: unknown.
