Description.

Female. Body length 4.75-4.8 mm (n=2).

Radicle color: darker than scape. Scape color: Yellowish. A4: longer than broad. A5: broader than long. Antennal club: formed, segments compact.

Interantennal process: not elongate. Median longitudinal elevation in frontal depression: absent. Frontal depression: concave. Frontal depression sculpture: without transverse or oblique carinae below submedian carina. Submedian carina: weak, shallow and rounded or formed by ledge. Submedian carina medially: without peak. Concavity across dorsal part of frontal depression: absent. Depression extending ventrally from median ocellus: absent. Upper frons: not hood-like. Malar area near antennal foramen: without carina or expansion. Malar area at mouth corner: with radiating striae. Smooth strip along posterior side of malar sulcus: present, broad throughout its length. Middle genal carina: absent. Direction of middle genal carina dorsally: absent (replace with question mark). Major sculpture of gena anteriorly: umbilicate-foveate; rugose. Major sculpture of gena posteriorly: umbilicate-foveate; rugose. Microsculpture of gena anteroventrally: absent. Microsculpture of gena posteroventrally: absent. Median carina extending posteriorly from hyperoccipital carina: absent. Hyperoccipital carina: indicated by rugae. Lateral connection between hyperoccipital and occipital carinae: absent. Area between vertex and occipital carina: umbilicate-foveate. Occipital carina medially: absent. Lateral corners of occipital carina: sharp and protruding.

Lateral pronotal area: without bulge projecting towards anterior pit. Epomial corner: weak. Netrion surface anteriorly: inflexed. Mesoscutum anteriorly: not steep. Mesoscutal median carina: absent or weak and incomplete in places. Longitudinal carina between median carina and notauli: absent. Major sculpture of medial mesoscutum anteriorly: umbilicate-punctate. Major sculpture of medial mesoscutum posteriorly: umbilicate-foveate; umbilicate-punctate. Microsculpture of medial mesoscutum anteriorly: granulate. Microsculpture of medial mesoscutum posteriorly: absent. Major sculpture of mesoscutellum: umbilicate-foveate; umbilicate-punctate. Microsculpture of mesoscutellum medially: absent. Microsculpture of mesoscutellum laterally: absent. Mesoscutellar apex: convex or straight. Setae along anterior limit of femoral depression: arising from tiny pits.

Number of carinae crossing speculum above femoral depression: 2. Number of carinae crossing femoral depression: 3-5. Mesepimeral sulcus pits: more than 5. Metascutellum dorsally: flat. Metascutellar sculpture dorsally: with scattered rugae. Median carina of metascutellum: absent or branched. Metascutellar setae: absent. Metascutellar apex: weakly emarginate. Metapleuron above ventral metapleural area: foveate or rugose. Metasomal depression setae: absent. Lateral propodeal carinae anteromedially: weakly diverging. Anterior areoles of metasomal depression: absent. Anterior longitudinal carinae in metasomal depression: absent. Lateral propodeal areas: meeting for only a short distance medially. Postmarginal vein: present. Fore wing apex: reaching apex of T4; reaching middle of T5.

T1 midlobe: obscured by other raised sculpture. T1: with small rounded anterior bulge, not reaching metascutellum. T2: with straight longitudinal striae or rugae. T6: longer than broad. Apical flange of T6: exposed apically. Metasomal apex: rounded. Major sculpture of T6: umbilicate-punctate; longitudinally striate or rugose. Microsculpture of T6: granulate.

Male. Unknown.

Diagnosis.

Female: Netrion anteriorly concave. Metascutellum tiny and broad, hardly extending beyond anterior margin of propodeum. Fore wings not long enough to reach T5. Oxyscelio flavipennis is one of two species of its genus with a strongly anteriorly concave netrion. The other, Oxyscelio cavinetrion , has a downward-directed face as in Oxyscelio flavipennis , but has a very different metascutellum.
