Diagnosis
Both sexes: Frontal depression shallow; transverse carinae present ventrally, interrupted; submedian carina indicated by rounded ruga. Hyperoccipital carina indicated by rugae. Occipital carina complete, convex medially. Metascutellum deeply concave, not or hardly emarginate apically, projecting dorsally. Postmarginal vein present but sometimes very short. Coxa not darker than rest of leg. T1 lateral carina expanded laterally. Metasomal flanges absent. Female: A4, A5 broader than long. Mesoscutellum without granulate sculpture. T1 midlobe with 4 longitudinal carinae. Main body of T6 not abruptly separated from apical rim, T6 not concave apically. Fore wing long enough to reach middle of T6 or beyond metasomal apex. Male: Flagellomeres beyond A3 not or hardly longer than broad. T1 midlobe with 4 longitudinal carinae. Fore wing long enough to reach to or beyond metasomal apex. T7 tiny, truncate or very weakly emarginate.

Comments
Oxyscelio hyalinipennis is a small-bodied member of the atricoxa-group with few distinctive features. Our concept of this species includes an unpublished Dodd species that he considered separate, differing from Oxyscelio hyalinipennis only in having a slightly larger body with a slightly longer metasoma. This variation is hypothesized by us to be the result of an increased body-size when parasitizing a slightly larger host.
