Description.

Female. Body length 3.3-3.85 mm (n = 13).

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 1-2 broadly interrupted transverse carinae. Median longitudinal elevation in frontal depression: absent. Major sculpture of gena anteroventrally: umbilicate-foveate. Major sculpture of gena posteroventrally: rugose; umbilicate-punctate. Microsculpture of gena anteroventrally: absent. Microsculpture of gena posteroventrally: granulate. Hyperoccipital carina: complete as a sharp carina. Median carina extending posteriorly from hyperoccipital carina: present, complete; present, anteriorly incomplete. Lateral connection between hyperoccipital and occipital carinae: present as a distinct carina. Area between vertex and occipital carina: rugose; umbilicate-punctate. Occipital carina medially: uniformly rounded. Lateral corners of occipital carina: sharp and protruding corners present.

Mesoscutum anteriorly: not steep. Mesoscutal median carina: present and complete. Major sculpture of mesoscutal midlobe anteriorly: umbilicate-foveate. Major sculpture of mesoscutal midlobe posteriorly: umbilicate-foveate. Microsculpture of mesoscutal midlobe anteriorly: granulate. Microsculpture of mesoscutal midlobe posteriorly: absent; granulate. 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; shallowly emarginate. Metapleuron above ventral metapleural area: crossed by carinae. Lateral propodeal carinae antero-medially: strongly 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 T5. Hind wing vein (Sc+R): not interrupted.

Carinae between T1 midlobe and T1 lateral carina: present. T1 midlobe: obscured by other raised sculpture. T1: with weak anterior bulge that does not closely approach metascutellum. T6: longer than broad. Metasomal apex: rounded. Major sculpture of T6: umbilicate-punctate; longitudinally striate or rugose. Microsculpture of T6: granulate.

Male. Body length 3.25-3.65 mm (n = 3). A5 tyloid: carina-like, not expanded. A11: longer than broad. T1 midlobe: with 4 longitudinal carinae. Metasomal apex: with acuminate lateral corners.

Diagnosis.

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

Etymology.
