Diagnosis
Both sexes: Frontal depression deep and broad but not parallel-sided, interrupted transverse carinae present dorsally; submedian carina sharp and strong. Hyperoccipital carina indicated by rugae. Occipital carina complete, convex medially. Metascutellum deeply concave, not or hardly emarginate apically, projecting dorsally. Postmarginal vein absent. Coxa not darker than rest of leg. T1 lateral carina expanded laterally. Metasomal flanges absent or with only very tiny sharp posterior corners. Female: A3 longer than pedicel. A4, A5 much broader than long. Mesoscutellum without granulate sculpture. T1 midlobe with 4 longitudinal carinae or with these obscured by raised sculpture. T6 without metasomal flanges, main body of tergum raised and vaguely separated from apical rim. Fore wing long enough to reach middle of T4 or base of T5. Male: Flagellomeres beyond A3 broader than long or only slightly longer than broad. T1 midlobe with 4 longitudinal carinae. Fore wing long enough to reach to or beyond T7. T7 truncate or very weakly emarginate.

Comments
Dodd (1913)[3] described Oxyscelio montanus from a single male specimen, of which the face is buried in glue. Identification of males in the atricoxa-group is problematic, but female specimens have been assigned to this species through reasoning that they likely had relatively short A4 and A5, and a strong submedian carina. Our concept of Oxyscelio montanus includes variation in radicle color, but intermediates between the two states (having a partially dark radicle) imply that this is a safe conclusion.
