Type locality
Peru, Avispas, near Marcapata, 30 m.
Type material
Holotype. Female (AEIC), first label, first line: Avispas, Peru second line: 30m nr. Marcapata third line: Oct. 1–15, 1962 fourth line: Luis Pena
Diagnosis
Face distinctly punctate, punctures separated by about 1 ? their diameter laterally, more closely spaced medially, nearly smooth between punctures. Eye in lateral view about 4.5 ? longer than temple; temples in dorsal view strongly receding. Female antenna with 31 flagellomeres; setae on basal flagellomeres short, moderately thick, dark. Mesoscutum anteriorly with distinct declivity; notaulus extending laterally towards tegula as groove bordered by distinct supramarginal carina. Propodeum mostly rugulose, especially anteriorly, with narrow, shallow median trough anteriorly confluent with large, broad, roughly pentagonal areola posteriorly. Fore wing 3RSa weakly curved, 1.4–1.5 ? longer than 2RS; m-cu postfurcal. T1 evenly curving into basal pit anteriorly, not distinctly declivitous, pit not delimited posterior-medially; surface rugulose throughout; dorsal carinae parallel-sided for most of their length, abruptly converging near posterior margin, not or only very weakly sinuate, rugulose but not transversely carinate between dorsal carinae. T2 and T3 smooth, polished throughout. Ovipositor long; ovipositor sheath about 1.5 ? longer than mesosoma. Head, body, hind coxa and femur light orange; antenna with whitish subapical ring; wing darkly infumate.
Remarks
This species is known only from the female holotype and is most similar to Opius marci, treated below. Both species have a pale subapical ring on the antenna (Fig. 47) whereas the flagellum is uniformly dark in all other species treated here. The setal pattern on the basal flagellomeres of these two species is also similar, with the setae shorter and not quite as thick as in species such as Opius albericus, but thicker and darker than in species such as Opius matthaei. Both species also have a relatively long ovipositor and relatively short antenna (with 29–31 flagellomeres). Exclusion of these two species from the ingenticornis species group is based primarily on the short antennae and the T1 profiles that are concave and gradually sloping anteriorly, and secondarily on the smaller pronope. Although Opius duplocarinatus and Opius marci are nearly identical, they have been placed in different subgenera (Fischer 1977[3], 1979a[7], b[4]) because Opius marci has very faintly shagreened sculpture on T2 and T2 sculpture is lacking in Opius duplocarinatus. There are also minor differences in the propodeum, with the areola more discrete in Opius marci, and Opius duplocarinatus has a distinct (though unsculptured) precoxal sulcus.
