Description.

Female. Body length 3.95 mm (n=1).

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

Ventral clypeal margin: concave. 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: without 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: indicated by a set of irregular elevations. Carina connecting occipital carina to hyperoccipital carina: absent. Occipital carina: present laterally, absent medially. Occiput sculpture: umbilicate foveate. Extra carina ventral to occipital carina: absent. Gena length: shorter than eye. Major sculpture of gena anteroventrally: umbilicate foveate. Major sculpture of gena posteroventrally: umbilicate foveate; rugose; umbilicate punctate. Microsculpture of gena anteroventrally: absent. Microsculpture of gena posteroventrally: granulate.

Lateral pronotal area sculpture: anteriorly smooth, posterodorsal corner with dense microsculpture, ventral corner with irregular carinae. Posterior border of central pronotal area: directed anteriorly, protruding at corner of epomial carina and transverse pronotal carina. Mesoscutum anteriorly: not steep, forming less than a right angle. Major sculpture of mesoscutal midlobe anteriorly: umbilicate foveate. Mesoscutal midlobe sculpture at midlength: not different from nearby sculpture. Major sculpture of mesoscutal midlobe posteriorly: umbilicate foveate; obliquely rugose. Microsculpture of mesoscutal midlobe anteriorly: granulate. Microsculpture of mesoscutal midlobe posteriorly: absent; granulate. Median mesoscutal carina: present as a vague, occasionally interrupted elevation. Major sculpture of mesoscutellum centrally: 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. Mesofemoral depression: longitudinally striate dorsally and ventrally. Metascutellum shape: not emarginate, forming a flat, concave shelf. Metascutellar setae: absent. Metascutellum sculpture: with three parallel and evenly spaced longitudinal carinae. Postmarginal vein: present. Fore wing apex at rest: reaching near apex of T5. Coxae color brightness: same color as 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.

T 1 horn: present. Number of longitudinal carinae of T1 midlobe: obscured by other raised sculpture. T1 lateral carina: straight. T2 sculpture: densely foveolate, longitudinal sculpture irregular. T2 sublateral longitudinal foveae: absent. T3 metasomal flanges: absent. T4 sculpture: longitudinally striate to rugose, setal pits spanning interspaces. T4 metasomal flanges: absent. T5 sculpture: longitudinally striate to rugose, setal pits spanning interspaces. T5 metasomal flanges: absent. T6: longer than broad. Major sculpture of T6: umbilicate punctate; longitudinally striate. Microsculpture of T6: absent. 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: 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: absent. S6 apex in relation to T6: not exposed to dorsal view. S6 apex: rounded or acuminate.

Male. unknown.

Diagnosis.

Both sexes: Frontal depression shallow, transverse carinae weak and interrupted; submedian carina strong but irregular. Hyperoccipital carina indicated by rugae. Occipital carina becoming weak or absent medially. Postmarginal vein present. Coxa not darker than rest of leg. Metasomal depression smooth. T1 lateral carina not expanded laterally. Metasomal flanges absent. Female only: A3 longer than pedicel. A4 longer than broad, A5 as long or longer than broad. Mesoscutellum without granulate sculpture. Metascutellum with 3 longitudinal carinae and some weak sculpture underlying them. T1 midlobe carinae obscured by raised smooth area. Fore wing long enough to reach middle of T5. Oxyscelio productionis is unusual in having 3 longitudinal carinae on the metascutellum. Otherwise it is very similar to some other species of the aciculae-group. Some other species of Oxyscelio may have a set of rugae on the metascutellum, but not 3 straight carinae.

Etymology.

Latin noun, genitive case, meaning "an extension."
