Description.

Female. Body length 4-4.15 mm (n=5).

Radicle color and shade: same as scape, both dark brown. Pedicel color: same as scape. A3: longer than pedicel. A4: broader than long. A5: broader than long.

Ventral clypeal margin: with elongate median lobe. Interantennal process: not elongate. Lower frons at dorsal margin of interantennal process: without transverse carina. Transverse curved rugae extending from frontal depression to eye: absent. Median longitudinal carina in frontal depression: absent. Ventral portion of frontal depression: smooth. Dorsal portion of frontal depression: with medially interrupted transverse carinae. Submedian carina: present only as a weak shift in elevation. Frontal depression dorsally: not hood-like, open dorsally. Upper frons major sculpture: umbilicate foveate; transversely rugose. Upper frons microsculpture: granulate. Hyperoccipital carina: indicated by a set of irregular elevations. Carina connecting occipital carina to hyperoccipital carina: absent. Occipital carina: uniformly rounded dorsally. Occiput sculpture: irregularly sculptured. Extra carina ventral to occipital carina: absent. Gena length: shorter than eye. Major sculpture of gena anteroventrally: rugose; umbilicate punctate. Major sculpture of gena posteroventrally: rugose; umbilicate punctate. Microsculpture of gena anteroventrally: absent. Microsculpture of gena posteroventrally: absent.

Lateral pronotal area sculpture: anteriorly smooth, posterodorsal corner with dense microsculpture, ventral corner with irregular carinae. Posterior border of central pronotal area: directed posteriorly, epomial carina absent or meeting transverse pronotal carina at arch on lateral surface of pronotum. Mesoscutum anteriorly: not steep, forming less than a right angle. Major sculpture of mesoscutal midlobe anteriorly: umbilicate punctate; irregularly rugose. Mesoscutal midlobe sculpture at midlength: not different from nearby sculpture. Major sculpture of mesoscutal midlobe posteriorly: longitudinally rugose; umbilicate punctate. Microsculpture of mesoscutal midlobe anteriorly: absent. Microsculpture of mesoscutal midlobe posteriorly: absent. Median mesoscutal carina: absent. Major sculpture of mesoscutellum centrally: umbilicate punctate. Major sculpture of mesoscutellum peripherally: umbilicate punctate. Microsculpture of mesoscutellum centrally: absent. Microsculpture of mesoscutellum peripherally: absent. Mesoscutellar rim: not expanded. Mesoscutellar rim medially: without notch. Mesofemoral depression: smooth. Metascutellum shape: slightly emarginate posteriorly, concave but elevated posteriorly. Metascutellar setae: present. Metascutellum sculpture: dense and irregular. Postmarginal vein: present. Fore wing apex at rest: reaching middle of T5. Coxae color brightness: same color as femora. Spines along tibiae: absent. Lateral propodeal carinae: broadly separated, but parallel for a short distance anteriorly. Setae in metasomal depression: absent. Anterior sculpture of metasomal depression: with median areole or pair of pits. Median propodeal carina: present.

T1 horn: absent. Number of longitudinal carinae of T1 midlobe: more than 6. T1 lateral carina: straight. T2 sculpture: mostly smooth with setiferous puncta medially, laterally with some longitudinal carinae. T2 sublateral longitudinal foveae: absent. T3 metasomal flanges: absent. T4 sculpture: mostly smooth, with tiny umbilicate foveae. T4 metasomal flanges: absent. T5 sculpture: mostly smooth, with tiny umbilicate foveae. T5 metasomal flanges: absent. T6: broader than long. Major sculpture of T6: umbilicate punctate. Microsculpture of T6: granulate. T6 medially: flat and tapering to a rounded apex, not separated from apical rim. T6 metasomal flanges: absent. T6 raised peripheral rim: absent. S4 sculpture: smooth, with tiny umbilicate foveae. S5 sculpture: smooth, with tiny umbilicate foveae. S5 median carina: absent. S6 peripheral carina: absent. S6 apex in relation to T6: not exposed to dorsal view. S6 apex: rounded or acuminate.

Male. unknown.

Diagnosis.

Both sexes: Body and limbs entirely dark brown. Frontal depression nearly flat, not crossed by carinae; submedian carina absent or weakly indicated by some rugae. Clypeus elongate. Hyperoccipital carina indicated by rugae. Occipital carina complete convex medially. Mesoscutellum smooth, with only some scattered setae. Metascutellum dorsally setose, broad and short, rugose. Postmarginal vein present. Metasomal depression sculptured antero-medially. T1 lateral carina not expanded. Metasomal sterna without longitudinal rugae or carinae. Metasomal flanges absent. Female: A3 longer than pedicel. A5 broader than long. T1 midlobe with 6 or more longitudinal carinae. T6 broader than long, apical rim not separated from main body of tergum. Oxyscelio oblongiclypei resembles Oxyscelio leviventris in many ways, but is very distinctive due to its setose metascutellum and elongate clypeus.

Etymology.

Latin noun, genitive case, meaning "oblong clypeus."
