Diagnosis. The entirely brown mesosoma distinguishes O. brevis from O. compacta females (male is unknown), which has the mesosoma yellow except for a brown spot covering almost the entire frenum.

Description. FEMALE. Body length 794 (n=1). Colour. Head, antenna except scape, pedicel and fl1, mesosoma, procoxa, and apical half of gaster brown; scape, pedicel mostly, fl1, petiole and legs except procoxa yellow. Wings with a brown suffusion over most of surface, somewhat less pronounced towards apex. Head. Head width 306 (n=1). Antenna. Funicle segments fl5 and fl7 with 2 mps ( Fig. 192 ). Antennal measurements (holotype), length/width (ratios of funicle segments): scape 309/63, pedicel 69/45, fl 1 37/28 (1.32), fl 2 26/28 (0.93), fl 3 30/39 (0.77), fl 4 26/28 (0.93), fl 5 40/30 (1.33), fl 6 28/31 (0.90), fl7 35/35 (1.0), fl 8 29/46 (0.63), clava 258/68. Mesosoma. Propodeum with submedian carinae not quite extending to dorsellum and slightly converging dorsally; sublateral carinae as long as submedian carinae ( Fig. 195 ). Wings. Fore wing ( Fig. 194 ) length (holotype) 1230, width 437, length/width 2.82, longest marginal setae 92. Hind wing length 946, width 52, longest marginal setae 118. Metasoma. Ovipositor sheath length (holotype) 273, distinctly shorter than metatibia length (374) and not exserted beyond apex of gaster ( Fig. 196 ).

MALE. Colour. Body darker brown than in female, with scape, pedicel, legs except brown metatibia, petiole and base and underside of gaster yellowish. Body length 819–1024 (n=2). Antenna. Measurements (n=1): scape length/width 118/37, pedicel length/width 55/39, flagellar segments length: fl1 70, fl2 80, fl3 89, fl4 99, fl5 93, fl6 91, fl7 94, fl8 92, fl9 95, fl10 94, fl11 96; total flagellar length 984; fl6 length/width 2.33, with 9 mps. Genitalia. As in generic description ( Figs 197, 198 ).

Etymology. The species name is a Latin adjective meaning short, referring to the short ovipositor sheaths.
