Female. Body length 3.75-5.2 mm (n=17).

Radicle color and shade: darker than scape. Pedicel color: same as scape. A3: longer than pedicel. A4: longer than broad. A5: as long as broad.

Ventral clypeal margin: with slightly convex 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: with medially interrupted transverse carinae. Dorsal portion of frontal depression: with some transverse carinae. Submedian carina: present. Frontal depression dorsally: not hood-like, open dorsally. Upper frons major sculpture: umbilicate foveate; irregularly rugose. Upper frons microsculpture: absent. Hyperoccipital carina: absent. Carina connecting occipital carina to hyperoccipital carina: absent. Occipital carina: weakly arched dorsally, with rounded lateral corners. Occiput sculpture: irregularly sculptured. Extra carina ventral to occipital carina: present, medially incomplete. Gena length: shorter than eye. Major sculpture of gena anteroventrally: umbilicate foveate; rugose. Major sculpture of gena posteroventrally: umbilicate foveate; rugose. Microsculpture of gena anteroventrally: absent. Microsculpture of gena posteroventrally: absent.

Lateral pronotal area sculpture: with shallow irregular carinae, posterodorsal corner with dense microsculpture. Posterior border of central pronotal area: directed anteriorly, protruding at corner of epomial carina and transverse pronotal carina. Mesoscutum anteriorly: very steep and tall, descending at a right angle or protruding anteriorly. Major sculpture of mesoscutal midlobe anteriorly: umbilicate foveate. Mesoscutal midlobe sculpture at midlength: with large smooth areas. Major sculpture of mesoscutal midlobe posteriorly: umbilicate foveate; longitudinally rugose. Microsculpture of mesoscutal midlobe anteriorly: granulate. Microsculpture of mesoscutal midlobe posteriorly: absent. Median mesoscutal carina: absent; present as a vague, occasionally interrupted el evation. Major sculpture of mesoscutellum centrally: absent; umbilicate foveate. Major sculpture of mesoscutellum peripherally: umbilicate foveate. Microsculpture of mesoscutellum centrally: absent. Microsculpture of mesoscutellum peripherally: absent. Mesoscutellar rim: not expanded. Mesoscutellar rim medially: without notch; with notch. Mesofemoral depression: longitudinally striate dorsally, smooth ventrally. Metascutellum shape: not emarginate, concave but elevated posteriorly. Metascutellar setae: absent. Metascutellum sculpture: with large smooth posterior fovea. Postmarginal vein: absent. Fore wing apex at rest: not reaching base of T5. Coxae color brightness: darker than femora. Spines along tibiae: absent. Lateral propodeal carinae: broadly separated, not parallel anteriorly. Setae in metasomal depression: absent. Anterior sculpture of metasomal depression: absent. Median propodeal carina: absent.

T1 horn: absent. Number of longitudinal carinae of T1 midlobe: 4. T1 lateral carina: protruding laterally, visible from ventral view. T2 sculpture: with longitudinal striae or rugae, setiferous puncta present between them. T2 sublateral longitudinal foveae: absent. T3 metasomal flanges: absent. T4 sculpture: longitudinally striate to rugose, setal pits spanning interspaces. T4 metasomal flanges: present as slightly protruding sharp corners. T5 sculpture: longitudinally striate to rugose, setal pits spanning interspaces. T5 metasomal flanges: present, rounded and lobe-like. T6: broader than long. Major sculpture of T6: umbilicate punctate; longitudinally striate. Microsculpture of T6: absent. T6 medially: with deep emargination that is V-shaped medially, separated from apical rim. T6 metasomal flanges: present as slightly expanded lateral rims, rounded posteriorly. T6 raised peripheral rim: absent. S4 sculpture: longitudinally striate or rugose, setal pits spanning interspaces. S5 sculpture: longitudinally striate to rugose, setal pits spanning interspaces. S5 median carina: present. S6 peripheral carina: present, posteriorly complete. S6 apex in relation to T6: exposed to dorsal view by T6 emargination. S6 apex: rounded or acuminate.

Male. Body length 3.4-4.45 mm (n=19). A3: longer than pedicel. A5 tyloid shape: narrow, linear. A6: broader than long. A11: longer than broad. Major sculpture of mesoscutal midlobe anteriorly: umbilicate foveate. Major sculpture of mesoscutal midlobe posteriorly: umbilicate foveate. Microsculpture of mesoscutal midlobe anteriorly: granulate. Microsculpture of mesoscutal midlobe posteriorly: absent. Major sculpture of mesoscutellum centrally: umbilicate foveate. Major sculpture of mesoscutellum peripherally: umbilicate foveate. Microsculpture of mesoscutellum centrally: absent; punctate. Microsculpture of mesoscutellum peripherally: absent. Fore wing apex at rest: reaching middle of T5. T1 midlobe longitudinal carinae: 5; obscured by other raised sculpture. T3 metasomal flanges: absent. T4 metasomal flanges: absent. T5 metasomal flanges: present as slightly protruding sharp corners. T6 metasomal flanges: present as sharp corners that do not protrude. T7: M-shaped, with a triangular median emargination.

Diagnosis.

Both sexes: Frontal depression deep, all carinae complete medially, carinae present above dorsal separator; submedian carina weakly defined or absent medially. Hyperoccipital carina absent. Occipital carina complete, medially weakly convex or sinuate. Mesoscutellar rim not expanded, with or without median notch. Metascutellum scoop-like, projecting dorsally. Coxa darker than rest of leg. Postmarginal vein absent. Female: A3 longer than pedicel. A4 longer than broad. A5 as long or longer than broad. T4 with very weak metasomal flanges. T5 with lobe-like metasomal flanges. T6 with expanded lateral margins. T6 deeply emarginate, angularly emarginate medially. S6 exposed to dorsal view, rounded apically. Male: A3, A4, A11 longer than broad. Mesoscutellum and mesoscutal midlobe posteriorly with small and densely set foveae, mesoscutellum without smooth area medially. T5 with weak and indistinct metasomal flanges, T6 with sharp metasomal flanges. T7 with long postero-lateral lobes, deeply emarginate medially, posterior margin M-shaped. Oxyscelio funis can be recognized with care using the long antenna of both sexes. The transversely carinate dorsal portion of the frontal depression is distinctive, and the Metasomal flanges are unusually weak.

Etymology.
