Description.

Female. Body length 4.25-4.65 mm (n=9).

Radicle color: darker than scape. Scape color: Yellowish. A4: longer than broad. A5: longer than broad. Antennal club: formed, segments compact.

Interantennal process: not elongate. Median longitudinal elevation in frontal depression: absent. Frontal depression: concave. Frontal depression sculpture: without transverse or oblique carinae below submedian carina. Submedian carina: indicated by multiple weak carinae. Submedian carina medially: without peak. Concavity across dorsal part of frontal depression: absent. Depression extending ventrally from median ocellus: absent. Upper frons: not hood-like. 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: rugose; umbilicate-punctate. Major sculpture of gena posteriorly: rugose; umbilicate-punctate. Microsculpture of gena anteroventrally: absent. Microsculpture of gena posteroventrally: granulate. Median carina extending posteriorly from hyperoccipital carina: absent. Hyperoccipital carina: indicated by rugae. Lateral connection between hyperoccipital and occipital carinae: absent. Area between vertex and occipital carina: umbilicate-foveate. Occipital carina medially: uniformly rounded. Lateral corners of occipital carina: not protruding.

Lateral pronotal area: without bulge projecting towards anterior pit. Epomial corner: weak. Netrion surface anteriorly: not inflexed. Mesoscutum anteriorly: not steep. Mesoscutal median carina: present and complete. Longitudinal carina between median carina and notauli: absent. Major sculpture of medial mesoscutum anteriorly: umbilicate-foveate. Major sculpture of medial mesoscutum posteriorly: umbilicate-foveate. Microsculpture of medial mesoscutum anteriorly: granulate. Microsculpture of medial mesoscutum posteriorly: absent. Major sculpture of mesoscutellum: umbilicate-foveate. Microsculpture of mesoscutellum medially: absent. Microsculpture of mesoscutellum laterally: absent. Mesoscutellar apex: convex or straight. Setae along anterior limit of femoral depression: arising from tiny pits. Number of carinae crossing speculum above femoral depression: 4. Number of carinae crossing femoral depression: more than 5. Mesepimeral sulcus pits: more than 5. Metascutellum dorsally: flat. Metascutellar sculpture dorsally: with scattered rugae. Median carina of metascutellum: absent or branched. Metascutellar setae: absent. Metascutellar apex: convex or straight. Metapleuron above ventral metapleural area: foveate or rugose. Metasomal depression setae: absent. Lateral propodeal carinae anteromedially: strongly diverging. Anterior areoles of metasomal depression: absent. Anterior longitudinal carinae in metasomal depression: absent. Lateral propodeal areas: separated medially. Postmarginal vein: present. Fore wing apex: reaching apex of T4; reaching middle of T5.

T1 midlobe: obscured by other raised sculpture. T1: with long anterior bulge, reaching metascutellum. T2: with straight longitudinal striae or rugae. T6: longer than broad. 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 3.85-4.15 mm (n=7). A5 tyloid: carina-like, not expanded. A11: longer than broad. Median tooth of frontal depression: absent. Median lobe of T1: with 6 longitudinal carinae. Metasomal apex: with acuminate lateral corners.

Diagnosis.

Both sexes: Upper frons with one or more extra carinae dorsal to submedian carina. Hyperoccipital carina indicated by rugae. Mesoscutellum without granulate sculpture. Mesofemoral depression crossed by more than 3 carinae below speculum. Female: Metascutellum subrectangular, with scattered weak rugae. T1 midlobe with long anterior bulge. T2 without sublateral depressions or curved striae. T6 longer than broad, tapering to a rounded apex. Oxyscelio florus differs from Oxyscelio mollitia , a similar Japanese species, in sculpture, metasomal length, and in having a much stronger T1 horn in females. Especially, the mesofemoral depression lacks a row of foveae along its anterior limit. Oxyscelio florus is very similar to the Taiwanese species Oxyscelio dermatoglyphes as well, especially in having extra carinae parallel to the submedian carina; these species differ in that Oxyscelio dermatoglyphes has no median carina on the mesoscutellum, only a very weak and indistinct one on the mesoscutum, and has a much shorter metasoma in females (fore wing long enough to reach T6 or apex of T5).

Etymology.

The Latin adjective florus has three forms, corresponding to gender agreement. Because Oxyscelio is a masculine genus based on initial species combination ( Kieffer 1907) and agreement with Scelio Latreille, the correct form is Oxyscelio florus .
