Diagnosis
Both sexes: Frontal depression shallow, transverse carinae absent or interrupted; submedian carina indicated by a weak ruga, flat or only weakly rounded dorsally. Hyperoccipital carina sharp and strong. Occipital carina incomplete, lateral portions nearly reaching hyperoccipital carina. Occiput almost entirely smooth, with a row of setiferous puncta. Mesoscutum without median carina. Metascutellum broad and concave, truncate or slightly convex apically, projecting dorsally. Postmarginal vein present. Coxa not darker than rest of leg. T1 lateral carina not expanded laterally. Metasomal flanges absent. Female: A3 much longer than pedicel. A4 longer than broad, A5 broader than long. Mesoscutellum weakly sculptured, with only setiferous puncta or small foveae. T1 midlobe with 4 longitudinal carinae. Fore wing long enough to reach T6. T6 broader than long. Male: A4 broader than long, A11 longer than broad; A5 tyloid narrow. T1 midlobe with 4 longitudinal carinae. Fore wing long enough to reach far beyond metasomal apex. T7 tiny, truncate.

Comments
Our concept of this species allows for considerable variation in sculpture and setation. The sculptural variation includes differences in the height and distinction of the submedian carina, strength of a longitudinal ridge along the median axis of the frontal depression, sculpture of the metasomal depression, and strength of the longitudinal elevations on the posteromedian part of the mesoscutal midlobe. Density of setation also may vary on the occiput and mesoscutellum. This variation does correlate with collection locality. It is possible that our concept of Oxyscelio flavipes applies to several sibling species, but no consistent patterns of variation were found to support that possibility.
