Type locality.

Peru, Quincemil, near Marcapata, 750 m.

Type material.

Holotype. Female (AEIC), first label, first line: Quincemil, Perú second line: 750 m nr. Marcapata third line: Nov. 10-15, 1962 fourth line: Luis Peña

Paratypes.

One female, one male (not seen), same data as holotype except ix.1962; one female, two males (not seen), same data except 20-30.x.1962.

Diagnosis.

Face shagreened throughout. Eye in lateral view 2-3 × longer than temple; temples in dorsal view not receding. Female antenna with 47-49 flagellomeres, male with up to 62 flagellomeres; setae on basal flagellomeres thin, pale. Mesoscutum anteriorly on nearly same plane as pronotum, without distinct anterior declivity; notaulus extending laterally towards tegula as groove bordered by distinct supramarginal carina. Propodeum coarsely, carinately rugose and shagreened, with short median trough anteriorly, areola largely obscured by sculpture posteriorly. Fore wing 3RSa very weakly curved, nearly straight, 1.25 × longer than 2RS; m-cu interstitial to very weakly postfurcal. T1 sharply declivitous anteriorly, pit delimited posterior-medially; surface very intensely shagreened; dorsal carinae distinctly elevated, nearly parallel-sided throughout, weakly converging near apex, not sinuate, not obviously transversely carinate between dorsal carinae. T2+T3 distinctly shagreened. Ovipositor short; ovipositor sheath about 0.3-0.4 × length of mesosoma. Head, body, hind coxa and femur orange; antenna without pale subapical ring; wing weakly infumate.

Remarks.

This species was originally described from the female holotype plus two female and three male paratypes, all from Peru. Opius ingenticornis is characterized by the extensively shagreened facial sculpture and pale body. This species is very similar to Opius rojam , newly described above, based on coloration, relatively small second submarginal cell of the fore wing, and propodeal sculpture. Opius ingenticornis is somewhat smaller, with T1 more intensively shagreened (Fig. 38) whereas Opius rojam is more rugose (Fig. 37). See remarks under Opius rojam , Opius filiflagellatus , and Opius gabrieli for additional characteristics and diagnostic features relative to other members of this species group.
