Description.

Female. Body length 4.85 mm (n=1).

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

Interantennal process: not elongate. Median longitudinal elevation in frontal depression: absent. Frontal depression: concave. Frontal depression sculpture: with 3-5 complete transverse carinae. Submedian carina: weak, shallow and rounded or formed by ledge. 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: with oblique tooth-like flange (facial nubbin). Malar area at mouth corner: without striae. Smooth strip along posterior side of malar sulcus: present, broad throughout its length. 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: indicated by rugae. Lateral connection between hyperoccipital and occipital carinae: present as a weak elevation. Area between vertex and occipital carina: umbilicate-foveate; irregularly rugose. Occipital carina medially: sinuate, concave medial to corners, but without a median peak. Lateral corners of occipital carina: sharp and protruding.

Lateral pronotal area: without bulge projecting towards anterior pit. Epomial corner: strong. 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; granulate. Mesoscutellar apex: roundly concave. Setae along anterior limit of femoral depression: arising from rows of foveae. Number of carinae crossing speculum above femoral depression: 2. Number of carinae crossing femoral depression: 3-5. Mesepimeral sulcus pits: 3-5. Metascutellum dorsally: convex. Metascutellar sculpture dorsally: with scattered rugae; granulate. Median carina of metascutellum: absent or branched. Metascutellar setae: absent. Metascutellar apex: deeply emarginate. Metapleuron above ventral metapleural area: crossed by carinae. 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: absent. Fore wing apex: reaching middle of T4.

T 1 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: granulate.

Male. Unknown.

Diagnosis.

Female: Antennal club formed. A4 longer than broad, A5 slightly broader than long. Face with oblique expanded flange between antennal foramen and eye. Gena with 5 carinae posteriorly. Metascutellum convex, deeply triangularly emarginate posteriorly. Fore wing long enough to reach middle of T4. T1 horn elongate, reaching metascutellum.

Etymology.

Latin noun, genitive case, meaning "a covering." Refers to how the metascutellum covers the T1 horn.
