Diagnosis. The brown head contrasting with the yellow mesosoma (except for a round brown spot covering the frenum) distinguishes females of O. compacta (male is unknown) from O. brevis (both head and mesosoma entirely brown).

Description. FEMALE. Body length 1024–1255 (n=5). Colour. Head, antenna except most of scape, frenum, part of gaster (gt4–gt5 and less so gt3) and, usually, metatibia brown; scape at extreme apex, mesosoma except frenum, most of gaster and legs, usually except metatibia, yellow. Head. Head ( Fig. 199 ) width 354–379 (n=2).

Antenna. Funicle segments fl5 and fl7 with 2 mps ( Fig. 199 ). Antennal measurements (holotype), length/width (ratios of funicle segments): scape 352–371/71–72, pedicel 71–75/44, fl1 41–49/31 (1.34–1.58), fl2 33–38/29–32 (1.12–1.22), fl3 40–41/29–30 (1.32–1.43), fl4 38–40/30–32 (1.19–1.33), fl5 52–53/34–36 (1.48–1.50), fl6 36–38/34– 37 (0.98–1.10), fl7 39–44/41–43 (0.91–1.07), fl8 37/53–58 (0.65–0.70), clava 246–254. Mesosoma. Propodeum with submedian carinae not quite extending to dorsellum and almost parallel; sublateral carinae as long as submedian carinae ( Fig. 202 ). Wings. Fore wing ( Fig. 202 ) length (n=2) 1185–1224, width 412–416, length/width 2.87–2.97, longest marginal setae 78–89. Hind wing length 936–994, width 56–60, longest marginal setae 112– 118. Metasoma. Ovipositor sheath length (n=2) 349–423, slightly shorter to slightly longer than metatibia length (~355–370) and slightly exserted beyond apex of gaster ( Figs 203, 204 ).

MALE. Unknown.

Etymology. The species name is a Latin adjective meaning compact.
