Description.

Female. Body length 2.55-2.6 mm (n = 2).

Radicle color: same as scape. A4: longer than broad; as long as broad. A5: broader than long. Upper frons: not hood-like. Frontal depression sculpture: with 2-4 complete transverse carinae; with 1-2 broadly interrupted transverse carinae. Median longitudinal elevation in frontal depression: absent. Major sculpture of gena anteroventrally: rugose; umbilicate-punctate. Major sculpture of gena posteroventrally: umbilicate-foveate; rugose. Microsculpture of gena anteroventrally: granulate. Microsculpture of gena posteroventrally: granulate. Hyperoccipital carina: wrinkle-like. 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. 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: weakly diverging. Metasomal depression setae: absent. Anterior areoles of metasomal depression: one or more areoles present. Anterior longitudinal carinae in metasomal depression: absent. Postmarginal vein: present. Fore wing apex: reaching beyond T6. Hind wing vein (Sc+R): interrupted.

Carinae between T1 midlobe and T1 lateral carina: present. T1 midlobe: with 6 or more longitudinal carinae. T1: without anterior bulge. T6: broader than long. Metasomal apex: rounded. Major sculpture of T6: umbilicate-punctate. Microsculpture of T6: absent.

Male. Body length 2.4 mm (n = 1). 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 wrinkle-like. Gena with granulate sculpture anteroventrally and posteroventrally. Mesoscutellum without granulate sculpture. Metascutellum about as broad as long. Metasomal depression not setose; lateral propodeal carinae weakly diverging. Hind wing Sc+R interrupted. Female: T1 midlobe without anterior horn.

Etymology.
