Major sculpture of mesoscutellum: umbilicate-foveate; irregularly rugose. Microsculpture of mesoscutellum medially: absent. Microsculpture of mesoscutellum laterally: absent. Mesoscutellar apex: convex or straight. Setae along anterior limit of femoral depression: arising from rows of foveae; arising from tiny pits. Number of carinae crossing speculum above femoral depression: 2. Number of carinae crossing femoral depression: more than 5. Mesepimeral sulcus pits: more than 5. Metascutellum dorsally: concave. Metascutellar sculpture dorsally: smooth or with transverse carinae. Median carina of metascutellum: absent or branched. Metascutellar setae: absent. Metas cutellar apex: convex or straight.

Metasomal apex: rounded. Major sculpture of T6: umbilicate-punctate; longitudinally striate or rugose. Microsculpture of T6: absent.

Male. Body length 2.95-5.25 mm (n=20). A5 tyloid: expanded, teardrop-shaped or sinuate. A11: broader than long. Median tooth of frontal depression: absent. Median lobe of T1: with 5 longitudinal carinae. Metasomal apex: with no distinct corners.

Diagnosis.

Both sexes: Middle genal carina short and angled towards genal carina dorsally. Hyperoccipital carina absent. Metascutellum concave dorsally, smooth aside from some transverse carinae. Female: A4, A5 broader than long. T1 midlobe with 5 longitudinal carinae. T6 broader than long. Male: A11 broader than long. A5 tyloid expanded, sinuate or teardrop-shaped. T7 with weakly rounded lobes posterolaterally. Oxyscelio reflectens is very similar Oxyscelio crebritas , but differs in the form of the genal ridge, the A5 tyloid in males, and the rounded apex of T7 in males. The lateral genal ridge maintains its shape and shortness even when it is weakly developed, and is usually visible as a strong ridge in dorsal view.

Etymology.

Latin participle not changing spelling under different genders, meaning “reflexed.” Refers to the way that the middle genal carina bends towards the posterior genal carina.

Comments.

Two distinct size ranges occur among specimen series, which is also the case in Oxyscelio capilli . As in the latter species, these are assumed to be the result of different-sized hosts.
