Description.

Female. Body length 3.25-3.5 mm (n=8).

Radicle color and shade: darker than scape; same as scape, both dark brown. Pedicel color: same as scape. A3: shorter than pedicel; as long as pedicel. A4: broader than long. A5: broader than long.

Ventral clypeal margin: with slightly convex median lobe. 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: absent. Frontal depression dorsally: not hood-like, open dorsally. Upper frons major sculpture: umbilicate foveate. Upper frons microsculpture: absent. Hyperoccipital carina: indicated by a set of irregular elevations. Carina connecting occipital carina to hyperoccipital carina: absent. Occipital carina: weakly arched dorsally, with rounded lateral corners. Occiput sculpture: irregularly sculptured. Extra carina ventral to occipital carina: present, complete. Gena length: shorter than eye. Major sculpture of gena anteroventrally: umbilicate foveate. Major sculpture of gena posteroventrally: umbilicate foveate; rugose. Microsculpture of gena anteroventrally: absent. Microsculpture of gena posteroventrally: granulate.

Lateral pronotal area sculpture: densely covered with setiferous puncta. Posterior border of central pronotal area: directed anteriorly, protruding at corner of epomial carina and transverse pronotal carina. Mesoscutum anteriorly: very steep and tall, descend ing at a right angle or protruding anteriorly. 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: granulate. Microsculpture of mesoscutal midlobe posteriorly: absent; granulate. Median mesoscutal carina: present as a ruga. Major sculpture of mesoscutellum centrally: umbilicate foveate. Major sculpture of mesoscutellum peripherally: umbilicate foveate. Microsculpture of mesoscutellum centrally: punctate. Microsculpture of mesoscutellum peripherally: punctate. Mesoscu tellar rim: not expanded. Mesoscutellar rim medially: without notch. Mesofemoral depression: longitudinally striate dorsally, smooth ventrally. Metascutellum shape: slightly emarginate posteriorly, concave but elevated posteriorly. Metascutellar setae: absent. Metascutellum sculpture: with large smooth posterior fovea. Postmarginal vein: present. Fore wing apex at rest: exceeding metasomal apex. Coxae color brightness: darker than femora. Spines along tibiae: absent. Lateral propodeal carinae: broadly separated, but parallel for a short distance anteriorly. Setae in metasomal depression: absent. Anterior sculpture of metasomal depression: absent. Median propodeal carina: absent.

T1 horn: absent. Number of longitudinal carinae of T1 midlobe: 4; obscured by other raised sculpture. T1 lateral carina: protruding laterally, visible from ventral view. 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: broader than long. Major sculpture of T6: umbilicate foveate. Microsculpture of T6: absent. T6 medially: strongly convex, tapering and sloping down 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: truncate.

Male. Body length 3.2-3.3 mm (n=3). A3: shorter than pedicel; as long as pedicel. A5 tyloid shape: narrow, linear. A6: broader than long. A11: longer than broad.

T6 metasomal flanges: absent. T7: truncate.

Diagnosis.

Both sexes: Frontal depression shallow and broad, crossed by some carinae above dorsal separator; submedian carina weak and irregular. Hyperoccipital carina indicated by rugae. Occipital carina complete, weakly convex medially. Metascutellum subrectangular, deeply concave, slightly emarginate apically, projecting dorsally. Coxa darker than rest of leg. T1 lateral carina expanded laterally. Metasomal flanges absent. Female: A3 not longer than pedicel. A4, A5, A6 broader than long. T1 midlobe with 4 longitudinal carinae anteriorly or with a slight smooth bump obscuring them. Fore wing long enough to reach or exceed metasomal apex. T6 broader than long, blunt apically. Male: A3 not longer than pedicel. A4, A11 broader than long. Fore wing long enough to reach T1 midlobe with 4 longitudinal midlobe carinae. T6 or to metasomal apex. T7 much broader than long, blunt apically, without posterior projections.
