Description.
Female. Body length 3.45 mm (n=1).
Radicle color: same color as scape. Scape color: Brown. A4: broader than long. 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: with 3-5 complete transverse carinae. 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: without striae. Smooth strip along posterior side of malar sulcus: absent or not consistently broad. Middle genal carina: present. Direction of middle genal carina dorsally: parallel to eye margin. Major sculpture of gena anteriorly: umbilicate-foveate. Major sculpture of gena posteriorly: rugose; umbilicate-punctate. Microsculpture of gena anteroventrally: absent. Microsculpture of gena posteroventrally: granulate. 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: uniformly rounded. Lateral corners of occipital carina: not protruding.
Lateral pronotal area: without bulge projecting towards anterior pit. Epomial corner: strong. Netrion surface anteriorly: not inflexed. Mesoscutum anteriorly: steep. Mesoscutal median carina: present and complete. Longitudinal carina between median carina and notauli: absent. Major sculpture of medial mesoscutum anteriorly: umbilicate-foveate. Major sculpture of medial mesoscutum posteriorly: umbilicate-punctate. Microsculpture of medial mesoscutum anteriorly: granulate. Microsculpture of medial mesoscutum posteriorly: absent. 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.
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. Metascutellar apex: convex or straight. Metapleuron above ventral metapleural area: foveate or rugose. Metasomal depression setae: absent. Lateral propodeal carinae anteromedially: strongly 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: absent. Fore wing apex: reaching apex of T5.
T1 midlobe: with 5 longitudinal carinae. T1: without anterior bulge. T2: with straight longitudinal striae or rugae. T6: broader than long. Apical flange of T6: ex posed apically. Metasomal apex: rounded. Major sculpture of T6: umbilicate-punctate. Microsculpture of T6: granulate.
Male. Unknown.
Diagnosis.
Female: A4, A5 broader than long. Frontal depression crossed by many carinae. Submedian carina undefined. Hyperoccipital carina indicated by rugae; occipital carina without distinct lateral corners. Mesoscutellum without granulate sculpture. Metascutellum tiny, narrow. T1 midlobe with 5 longitudinal carinae. Fore wings long enough to reach apex of T5. T6 broader than long. Oxyscelio lacunae is an unusual species that resembles Oxyscelio crebritas in some ways, but has an indistinct submedian carina, tiny metascutellum, and irregular metapleural sculpture. The overall body color is dark, with the scape, wings, and coxae brownish.
Etymology.
