Diagnosis.

Face distinctly punctate, punctures separated by about 1 × their diameter, strongly shagreened adjacent eye margin, otherwise mostly weakly shagreened between punctures. Eye in lateral view 2.0-2.5 × longer than temple; temples in dorsal view not receding. Antenna of female with 56 flagellomeres, allotype with 54 flagellomeres; setae on basal flagellomeres thick, dark. 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 rugose, median areola absent, median trough anteriorly deep, short, distinct. Fore wing 3RSa straight, about 1.6 × longer than 2RS; m-cu postfurcal. T1 declivitous anteriorly at about a 45 degree angle, basal pit delimited posterior-medially; surface shagreened throughout; dorsal carinae weakly elevated, sinuate, widest subapically, narrowing apically, without obvious transverse carinae between dorsal carinae. T2 uniformly, distinctly shagreened; T3 mostly weakly shagreened, smoother and very finely punctate laterally. Ovipositor short, barely protruding; ovipositor sheath roughly 0.4 × length of mesosoma. Head, mesosoma, T1, T3-T6 dark reddish brown to dark brown; T2 white with narrow, dark brown lateral margins; hind coxa white; hind femur almost completely dark reddish brown; antenna without subapical pale ring; wing lightly infumate.

Remarks.

This species was described from the holotype female and three additional paratype females, all from Peru. Fischer (1978) subsequently recorded a male and a female from the state of Pará in Brazil. This species is nearly identical to Opius albericus (see remarks above under that species), differing only in minor details, most notably in the relative size of the eye.
