Mostly ferruginous except: antenna basally light brown, becoming dark brown-black towards the apex; head black; propleuron, black posteriorly; mesonotum with lateral mesonotal lobes blackish ( Fig. 11 ); mesopleuron ventrally black; fore and mid legs brown with coxa, trochanter and trochantellus whitish; hind legs with coxa black, except ferruginous area dorsally, trochanter, trochantellus and base of femur whitish, remaining of femur ferruginous, base of tibia whitish, remaining of tibia and tarsus black-dark brown; T2–T8 and sterna ferruginous-yellowish ( Fig. 14 ); wings hyaline.

Body length. 5.63 mm.

Head. Antenna with 27 flagellomeres; flagellomeres length/width ratio as follows: F1 = 4.91; F2 = 4.48; F3 = 4.09; F25 = 1.80; F 26 = 1.77; F27 = 2.25; head width 1.27× head height; head height 1.57× eye height; face maximum width 1.33× its minimum width; face minimum width 0.88× clypeus width ( Fig. 10 ); malar space length 0.36× mandible width basally; temple length 0.60× eye length in dorsal view; ocellar-ocular distance 2.37× ocellar diameter ( Fig. 9 ); occipital carina complete; mandibles not twisted; frons smooth and polished; face smooth near clypeus, becoming rugulose towards the antennal sockets; clypeus smooth with sparse punctuation.

Legs. Tarsal claw simple; hind coxa punctate, with a rugulose area dorsally.

Wings. Fore wing: length 4.61 mm; vein r 0.35× length of vein 3 Rsa; vein 3 Rsa 0.95× length of vein r-m; vein m-cu antefurcal. Hind wing: vein 1M 0.95× length of vein cu-a; vein 1M 0.91× length of vein r-m.

Metasoma. Dorsope absent; ventral borders of first tergite touching for a short distance distally; T1 rugulose ( Fig. 13 ), remaining tergites smooth; ovipositor not thickened basally and straight. Ovipositor 1.79× first tergite length.

Female variation. Body length 4.61–5.58 mm; antenna with 27–28 flagellomeres; antenna black-dark brown with pedicel and scape light brown; propleuron black; pronotum dorsally black; ferruginous areas of mesosoma ranging from reddish to brownish; head width 1.27–1.40× head height; head height 1.57–1.62× eye height; face maximum width 1.27–1.37× its minimum width; face minimum width 0.88–0.94× clypeus width; malar space length 0.31–0.42× mandible width basally; temple length 0.50–0.60× eye length in dorsal view; ocellar-ocular distance 2.37–2.50× ocellar diameter. Fore wing: length 3.58–3.84 mm; vein r 0.29–0.39× length of vein 3 Rsa; vein 3 Rsa 0.95–1.00× length of vein r-m. Hind wing: vein 1M 1.05–1.06× length of vein cu-a; vein 1M 0.64–0.76× length of vein r-m; ovipositor 1.85–2.63× T1 length; precoxal sulcus carinate-rugulose.; mesopleuron punctate with a rugulose area near tegula; T1 laterally costate.

Comments. Meteorus ferruginosus n. sp. is most similar to M. megalops Zitani and M. gigas Aguirre, Shaw & Jones , with a complete occipital carina, ventral borders of first tergite touching for a short distance, dorsope absent and mandibles not twisted, but can be distinguished by having the metasoma and mesosoma predominantly ferruginous, head height 1.57–1.62× eye height and ovipositor 1.85–2.63× T1 length. In the key to Neotropical species of Meteorus by Aguirre et al. (2015), M. ferruginosus keys to couplet 75, and is also near M. megalops and M. gigas .
