Description.

Female. Body length 4.3-4.85 mm (n=7).

Radicle color and shade: darker than scape. Pedicel color: at least partially darker than scape. A3: longer than pedicel. A4: longer than broad. A5: longer than broad.

Ventral clypeal margin: concave. Interantennal process: not elongate. Lower frons at dorsal margin of interantennal process: without transverse carina. Transverse curved rugae extending from frontal depression to eye: absent. Median longitudinal carina in frontal depression: absent. Ventral portion of frontal depression: smooth. Dorsal portion of frontal depression: without transverse carinae. Submedian carina: present. Frontal depression dorsally: not hood-like, open dorsally. Upper frons major sculpture: umbilicate foveate; transversely rugose. Upper frons microsculpture: absent. Hyperoccipital carina: indicated by a set of irregular elevations. Carina connecting occipital carina to hyperoccipital carina: absent. Occipital carina: present laterally, absent medially. Occiput sculpture: irregularly sculptured. Extra carina ventral to occipital carina: absent. Gena length: shorter than eye. Major sculpture of gena anteroventrally: umbilicate foveate. Major sculpture of gena posteroventrally: umbilicate punctate. Microsculpture of gena anteroventrally: absent. Microsculpture of gena posteroventrally: granulate.

Lateral pronotal area sculpture: mostly granulate, ventral corner with irregular carinae. Posterior border of central pronotal area: directed posteriorly, epomial carina absent or meeting transverse pronotal carina at arch on lateral surface of pronotum. Mesoscutum anteriorly: not steep, forming less than a right angle. Major sculpture of mesoscutal midlobe anteriorly: umbilicate foveate. Mesoscutal midlobe sculpture at midlength: not different from nearby sculpture. Major sculpture of mesoscutal midlobe posteriorly: umbilicate foveate. Microsculpture of mesoscutal midlobe anteriorly: absent. Microsculpture of mesoscutal midlobe posteriorly: absent. Median mesoscutal carina: absent. Major sculpture of mesoscutellum centrally: umbilicate foveate. Major sculpture of mesoscutellum peripherally: umbilicate foveate. Microsculpture of mesoscutellum centrally: absent. Microsculpture of mesoscutellum peripherally: absent. Mesoscutellar rim: not expanded. Mesoscutellar rim medially: without notch. Mesofemoral depression: longitudinally striate dorsally and ventrally. Metascutellum shape: not emarginate, convex dorsally. Metascutellar setae: absent. Metascutellum sculpture: with many longitudinal rugae. Postmarginal vein: present. Fore wing apex at rest: reaching base of T5. Coxae color brightness: same color as femora. Spines along tibiae: absent. Lateral propodeal carinae: broadly separated, not parallel anteriorly. Setae in metasomal depression: absent. Anterior sculpture of metasomal depression: absent. Median propodeal carina: absent.

T1 horn: present. Number of longitudinal carinae of T1 midlobe: obscured by other raised sculpture. T1 lateral carina: straight. T2 sculpture: with longitudinal striae or rugae, setiferous puncta present between them. T2 sublateral longitudinal foveae: absent. T3 metasomal flanges: absent. T4 sculpture: longitudinally striate to rugose, setal pits spanning interspaces. T4 metasomal flanges: absent. T5 sculpture: longitudinally striate to rugose, setal pits spanning interspaces. T5 metasomal flanges: absent. T6: longer than broad. Major sculpture of T6: umbilicate punctate; longitudinally striate. Microsculpture of T6: absent. T6 medially: flat and tapering to a rounded apex, not separated from apical rim. T6 metasomal flanges: absent. T6 raised peripheral rim: absent. S4 sculpture: longitudinally striate or rugose, setal pits spanning interspaces. S5 sculpture: longitudinally striate to rugose, setal pits spanning interspaces. S5 median carina: present. S6 peripheral carina: absent. S6 apex in relation to T6: not exposed to dorsal view. S6 apex: rounded or acuminate.

Male. unknown.

Diagnosis.

Both sexes: Frontal depression shallow, transverse carinae absent; submedian carina sharp. Hyperoccipital carina indicated by rugae. Occipital carina absent medially, lateral corners not protruding. Postmarginal vein present. Coxa not darker than rest of leg. T1 lateral carina not expanded laterally. Metasomal flanges absent. Female: A4 longer than broad, A5 about as long as broad. Mesoscutellum without granulate sculpture. Metascutellum broad and short, slightly convex, irregularly rugose. Fore wing long enough to reach base of T5. T6 longer than broad.
