Description.

Female. Body length 3.08 mm (n = 1).

Radicle color: same color as scape. Scape color: dark brown. A4: as long as broad. A5: broader than long. Antennal club in female: formed, segments compact.

Interantennal process: not elongate. Median longitudinal elevation in frontal depression: absent. Frontal depression: concave. Frontal depression sculpture: with 3 broadly interrupted transverse carinae below submedian carina. Submedian carina: strong, formed by a sharp raised carina. Submedian carina medially: with sharp 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. Facial striae: present. Smooth strip along posterior side of malar sulcus: absent or not consistently broad. Genal carina: present. Direction of genal carina dorsally: parallel to eye margin. Major sculpture of gena anteriorly: smooth with scattered punctures. Major sculpture of gena posteriorly: rugulose with scattered punctures. 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: foveate. Occipital carina medially: uniformly rounded. Lateral corners of occipital carina: protruding.

Lateral pronotal area: without bulge projecting towards anterior pit. Transverse pronotal carina: present anteriorly and forming a corner with epomial carina. Netrion surface anteriorly: not inflected. Mesoscutum anteriorly: steep. Mesoscutal median carina: present and complete. Longitudinal carina between median carina and notauli: absent. Major sculpture of medial mesoscutum anteriorly: punctate. Major sculpture of medial mesoscutum posteriorly: punctate. Microsculpture of medial mesoscutum anteriorly: granulate. Microsculpture of medial mesoscutum posteriorly: absent. Major sculpture of mesoscutellum: 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 rows of foveae. Number of carinae crossing speculum above femoral depression: 3. Number of carinae crossing femoral depression: more than 5. Mesepimeral sulcus pits: more than 5. Metascutellum dorsally: concave. Metascutellar sculpture dorsally: smooth. Median carina of metascutellum: absent. Metascutellar setae: absent. Metascutellar apex: straight. Metapleuron above ventral metapleural area: crossed by carinae. 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: separated medially. Postmarginal vein: absent. Fore wing apex: reaching beyond T6.

T1 midlobe: with 6 longitudinal carinae. T1: without anterior bulge. T2: with straight longitudinal striae or rugae. T6: broader than long. Metasomal apex: rounded. Major sculpture of T6: punctate. Microsculpture of T6: absent. S2: with longitudinal rugae. S5: with longitudinal striae. S6: punctate rugose.

Male. Unknown.

Diagnosis.

Female: A4 as long as broad, A5 broader than long. Frons without elevation between antennal foramen and eye. Upper frons not hood-like. Hyperoccipital carina indicated by rugae. Medial mesoscutum punctate posteriorly. Metascutellum without dorsal setae, mooth. T1 with 6 longitudinal carinae. Oxyscelio apheles is similar to O. vittae Burks but can be separated from the latter by the following characters: radicle, scape and coxae blackish, metapleuron above ventral metapleural area crossed by carinae.

Etymology.

The name apheles refers to the smooth metascutellum of this species. The epithet is used as a noun in apposition.
