Description.

Male. Body length 3.55 mm (n = 1).

Radicle color: same as scape. A5 tyloid: carina-like, not expanded. A11: longer than broad. Upper frons: not hood-like. Frontal depression sculpture: without transverse or oblique carinae below submedian carina. Median longitudinal elevation in frontal depression: present. 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. Hyperoccipital carina: wrinkle-like. Median carina extending posteriorly from hyperoccipital carina: absent. Lateral connection between hyperoccipital and occipital carinae: absent. Area between vertex and occipital carina: umbilicate-foveate; rugose. Occipital carina medially: uniformly rounded. Lateral corners of occipital carina: absent.

Mesoscutum anteriorly: not steep. Mesoscutal median carina: absent or incomplete. 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: umbilicate-foveate; longitudinally rugose. Microsculpture of mesoscutellum medially: absent. Microsculpture of mesoscutellum laterally: absent. Number of carinae crossing femoral depression: 4 or more. Mesepimeral sulcus pits: more than 5. Setae along anterior limit of femoral depression: arising from tiny pits. Metascutellum dorsally: concave. Metascutellar sculpture centrally: smooth. Metascutellar apex: convex or straight. Metapleuron above ventral metapleural area: crossed by carinae. Lateral propodeal carinae antero-medially: weakly diverging. Metasomal depression setae: present. Anterior areoles of metasomal depression: one or more areoles present. Anterior longitudinal carinae in metasomal depression: absent. Postmarginal vein: present. Hind wing vein (Sc+R): not interrupted.

Carinae between T1 midlobe and T1 lateral carina: absent. T1 midlobe: with 5 longitudinal carinae. Metasomal apex: with no distinct corners.

Diagnosis.

Both sexes: Hyperoccipital carina wrinkle-like, not connected to occipital carina laterally or medially. Frontal depression with median carina. Mesoscutellum without granulate sculpture. Metasomal depression setose; lateral propodeal carinae broadly separated. Hind wing Sc+R not interrupted. Male: T7 without acuminate lateral corners.

Etymology.

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

Holotype, male: TANZANIA: Iringa Reg., Kilolo Dist., Udzungwa (Uzungwa) Mts., Luwala (Luwato) Camp area, semi-evergreen montane tropical virgin forest edge, Ndundulu Forest, 1880m, 18. I– 25.I.2007, malaise trap, L. A. Hansen & A. Hedayat, OSUC369369 (deposited in BMNH).

Comments.

Oxyscelio intensionis bears some resemblance to several Australian species of the aciculae group, especially to Oxyscelio divisionis Burks. None of the species within that group has a setose metasomal depression.
