Description.

Female. Body length 2.6-3.75 mm (n=20).

Radicle color: same color as scape; darker than scape. Scape color: Yellowish. A4: broader than long. A5: broader than long. Antennal club: formed, segments compact.

Interantennal process: not elongate. Median longitudinal elevation in frontal depression: absent; present. Frontal depression: concave. Frontal depression sculpture: with 3 or more broadly interrupted transverse carinae. Submedian carina: strong, formed by a sharp raised carina. Submedian carina medially: without peak. Concavity across dorsal part of frontal depression: absent. Depression extending ventrally from median ocellus: absent. Upper frons: hood-like, protruding over pedicel when antenna at rest. Malar area near antennal foramen: without carina or expansion. Malar area at mouth corner: with radiating 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: umbilicate-foveate; rugose. Microsculpture of gena anteroventrally: absent. Microsculpture of gena posteroventrally: absent. Median carina extending posteriorly from hyperoccipital carina: absent. Hyperoccipital carina: complete, continuous with anterior genal carina. Lateral connection between hyperoccipital and occipital carinae: absent. Area between vertex and occipital carina: irregularly rugose. Occipital carina medially: sinuate, concave medial to corners, but without a median peak. Lateral corners of occipital carina: not protruding.

Lateral pronotal area: with slight bulge projecting anteriorly towards anterior pit. Epomial corner: weak. 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; transversely rugose. Major sculpture of medial mesoscutum posteriorly: umbilicate-foveate; transversely rugose. Microsculpture of medial mesoscutum anteriorly: granulate. Microsculpture of medial mesoscutum posteriorly: absent. Major sculpture of mesoscutellum: umbilicate-foveate; longitudinally 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: 3; 4. 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: weakly emarginate. Metapleuron above ventral metapleural area: crossed by carinae. Metasomal depression setae: absent. Lateral propodeal carinae anteromedially: weakly diverging. Anterior areoles of metasomal depression: one or more areoles present. Anterior longitudinal carinae in metasomal depression: absent. Lateral propodeal areas: separated medially. Postmarginal vein: present. Fore wing apex: reaching apex of T6; reaching middle of T6.

T1 midlobe: with 4 longitudinal carinae. T1: without anterior bulge. T2: with straight longitudinal striae or rugae. T6: broader than long. Apical flange of T6: exposed apically. Metasomal apex: rounded. Major sculpture of T6: umbilicate-punctate; longitudinally striate or rugose. Microsculpture of T6: absent.

Male. Body length 2.95-3.8 mm (n=20). A5 tyloid: carina-like, not expanded. A11: broader than long. Median tooth of frontal depression: absent. Median lobe of T1: with 4 longitudinal carinae. Metasomal apex: with acuminate lateral corners.

Diagnosis.

Both sexes: Frons without elevation between antennal foramen and eye. Hyperoccipital carina present and sharp, continuous with anterior genal carina. Mesoscutellum without granulate sculpture. Metascutellum without dorsal setae. Propodeum without median carina; lateral propodeal carinae narrowly separated anteriorly. Female: T1 midlobe with 4 longitudinal carinae. T6 rounded apically. Male: A11 broader than long. T1 midlobe with 4 longitudinal carinae. T7 with acuminate posterolateral corners. Oxyscelio cuculli is similar to Oxyscelio granorum , but is usually smaller and has strongly foveate surface sculpture. Additionally, these species differ in A11 length and in shape of the T7 apex in males.

Etymology.

Latin noun, genitive case, meaning “hood.”
