Description.

Female. Body length 3.35 mm (n = 1).

Radicle color: same as scape. A4: longer than broad. A5: longer than broad; as long as broad. Upper frons: not hood-like. Frontal depression sculpture: with 2-4 complete transverse carinae. Median longitudinal elevation in frontal depression: absent. Major sculpture of gena anteroventrally: umbilicate-foveate. Major sculpture of gena posteroventrally: absent. Microsculpture of gena anteroventrally: absent. Microsculpture of gena posteroventrally: granulate. Hyperoccipital carina: complete as a sharp carina. Median carina extending posteriorly from hyperoccipital carina: absent. Lateral connection between hyperoccipital and occipital carinae: absent. Area between vertex and occipital carina: rugose; umbilicate-punctate. Occipital carina medially: uniformly rounded. Lateral corners of occipital carina: absent.

Mesoscutum anteriorly: not steep. Mesoscutal median carina: present and complete; absent or incomplete. Major sculpture of mesoscutal midlobe anteriorly: umbilicate-foveate; umbilicate-punctate. Major sculpture of mesoscutal midlobe posteriorly: umbilicate-foveate; obliquely rugose. Microsculpture of mesoscutal midlobe anteriorly: granulate. Microsculpture of mesoscutal midlobe posteriorly: absent. Major sculpture of mesoscutellum: umbilicate-foveate; obliquely 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 rows of foveae. 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: strongly diverging; weakly diverging. Metasomal depression setae: absent. Anterior areoles of metasomal depression: absent. Anterior longitudinal carinae in metasomal depression: absent. Postmarginal vein: present. Fore wing apex: reaching middle of T6. Hind wing vein (Sc+R): not interrupted.

Carinae between T1 midlobe and T1 lateral carina: present. T1 midlobe: with 5 longitudinal carinae; with 6 or more longitudinal carinae. T1: without anterior bulge. T6: broader than long; as long as broad. Metasomal apex: rounded. Major sculpture of T6: umbilicate-punctate; longitudinally striate or rugose. Microsculpture of T6: granulate.

Male. Body length 3.2 mm (n = 1). A5 tyloid: carina-like, not expanded. A11: longer than broad. T1 midlobe: with 5 longitudinal carinae. Metasomal apex: with acuminate lateral corners.

Diagnosis.

Both sexes: Hyperoccipital carina present and sharp, not connected to occipital carina laterally; median carina between hyperoccipital and occipital carinae absent. Gena with granulate sculpture posteroventrally but not anteroventrally. Mesoscutellum without granulate sculpture. Metasomal depression without median carina; lateral propodeal carinae strongly or weakly diverging. Hind wing Sc+R vein complete. Female: A4 longer than broad.

Etymology.
