Diagnosis.

Face distinctly punctate, punctures separated by 1-2 × their diameter, smooth between punctures. Eye in lateral view about 3.8-4.0 × longer than temple; temples in dorsal view receding. Female antenna with 29 flagellomeres; setae on basal flagellomeres short, thick, dark. Mesoscutum anteriorly with distinct declivity; notaulus extending laterally towards tegula as groove bordered by distinct supramarginal carina. Propodeum weakly rugulose to smooth with anterior median trough separated from well-defined, discretely margined, pentagonal areola posteriorly. Fore wing 3RSa weakly curved, 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, at least medially; dorsal carinae parallel-sided throughout, not sinuate, trans versely carinate between dorsal carinae. T2 very faintly shagreened medially, mostly smooth, polished; T3 smooth, polished. Ovipositor long; ovipositor sheath about 1.3-1.4 × longer than mesosoma. Head, body, hind coxa and femur pale orange; antenna with pale subapical ring; wing infumate.

Remarks.

This species is known only from the female holotype. It is nearly identical to Opius duplocarinatus , but has a somewhat more discrete propodeal areola. See remarks section under Opius duplocarinatus for additional comparisons and rationale for exclusion from the ingenticornis species group.
