Description.

Female. Body length 3.65 mm (n = 1).

Radicle color: same color as scape. Scape color: yellowish. A4: longer than broad. A5: longer than broad. Antennal club in female: formed, segments compact.

Interantennal process: not elongate. Median longitudinal elevation in frontal depression: absent. Frontal depression: flat. Frontal depression sculpture: with 3-5 complete transverse carinae below submedian carina. Submedian carina: rather weak, only upper portion developed. 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. Facial striae: present. Smooth strip along posterior side of malar sulcus: present, broad throughout its length. Genal carina: absent. Major sculpture of gena anteriorly: punctate. Major sculpture of gena posteriorly: rugose; punctate. Microsculpture of gena anteroventrally: absent. Microsculpture of gena posteroventrally: absent. 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: foveate. Occipital carina medially: absent. Lateral corners of occipital carina: sharp and protruding.

Lateral pronotal area: without bulge projecting towards anterior pit. Transverse pronotal carina: absent anteriorly. Netrion surface anteriorly: not inflected. Mesoscutum anteriorly: steep. Mesoscutal median carina: present and complete. Longitudinal carina between median carina and notauli: absent. Major sculpture of medial mesoscutum anteriorly: foveate; rugose. Major sculpture of medial mesoscutum posteriorly: foveate. Microsculpture of medial mesoscutum anteriorly: granulate. Microsculpture of medial mesoscutum posteriorly: absent. Major sculpture of mesoscutellum: foveate. Microsculpture of mesoscutellum medially: absent. Microsculpture of mesoscutellum laterally: absent. Mesoscutellar apex: straight. Setae along anterior limit of femoral depression: arising from rows of foveae. Number of carinae crossing speculum above femoral depression: 3. Number of carinae crossing femoral depression: more than 5. Mesepimeral sulcus pits: more than 5. Metascutellum dorsally: concave. Metascutellar sculpture dorsally: areolate. Median carina of metascutellum: absent. Metascutellar setae: with many dorsal setae. Metascutellar apex: weakly emarginate. Metapleuron above ventral metapleural area: crossed by carinae. Metasomal depression setae: not visible. Lateral propodeal carinae anteromedially: strongly diverging. Anterior areoles of metasomal depression: not visible. Anterior longitudinal carinae in metasomal depression: not visible. Lateral propodeal areas: separated medially. Postmarginal vein: absent. Fore wing apex: reaching apex of T5.

T1 midlobe: obscured by other raised sculpture. T1: with anterior bulge. T2: with straight longitudinal striae. T6: longer than broad. Metasomal apex: rounded. Major sculpture of T6: punctate. Microsculpture of T6: absent. S2: with longitudinal rugae. S5: with longitudinal striae. S6: punctate.

Male. Unknown.

Diagnosis.

Female: A4 and A5 longer than broad. Frontal depression flat. Submedian carina of frons weak, only upper portion developed. Gena without middle carina. Occipital carina absent medially. Metascutellum areolate, with many dorsal setae. T1 with anterior bulge. The above diagnostic characters make O. amalocarina unique and can be easily separated from other species of Oxyscelio .

Etymology.

The name amalocarina refers to the weak submedian carina of this species. The epithet is used as a noun in apposition.
