Description
Female. Body length 2.95–3.95 mm (n=20).
Radicle color and shade: same as scape, both yellowish or reddish. Pedicel color: same as scape. A3: as long as pedicel. A4: broader than long. A5: broader than long.
Ventral clypeal margin: uniformly convex. 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: with medially interrupted transverse carinae. 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; irregularly rugose. 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. Microsculpture of gena anteroventrally: absent. Microsculpture of gena posteroventrally: absent.
Lateral pronotal area sculpture: with shallow irregular carinae, posterodorsal corner with dense microsculpture. Posterior border of central pronotal area: directed anteriorly, protruding at corner of epomial carina and transverse pronotal carina. Mesoscutum anteriorly: very steep and tall, descending 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. Median mesoscutal carina: present as a vague, occasionally interrupted elevation. 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, smooth ventrally. Metascutellum shape: slightly emarginate posteriorly, concave but elevated posteriorly. Metascutellar setae: absent. Metascutellum sculpture: with large smooth posterior fovea. Postmarginal vein: absent. Fore wing apex at rest: reaching middle 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: absent. Number of longitudinal carinae of T1 midlobe: 4. 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: present as slightly protruding sharp corners. T5 sculpture: longitudinally striate to rugose, setal pits spanning interspaces. T5 metasomal flanges: present as strong posterior corners. T6: broader than long. Major sculpture of T6: umbilicate punctate. Microsculpture of T6: absent. T6 medially: with deep emargination that is V-shaped medially, separated from apical rim. T6 metasomal flanges: present as slightly expanded lateral rims, rounded posteriorly. 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 deep, with interrupted carinae ventrally, dorsal separator complete medially, weakly indicated carinae present above dorsal separator; submedian carina distinct but not strongly projecting. Hyperoccipital carina indicated by vague rugae. Occipital carina complete, medially weakly convex. Mesoscutellar rim not expanded, without median notch. Metascutellum small, weakly emarginate apically, projecting dorsally. Coxa same color as rest of leg. Postmarginal vein absent. Female: A3 longer than pedicel. A4, A5 broader than long. T4, T5 without distinct metasomal flanges. T6 abruptly narrower than T5, without expanded lateral margins. Main surface of T6 strongly emarginate medially, with sharp posterior corners, sharply separated from apical rim. S6 exposed to dorsal view, rounded apically.
Etymology
Latin noun, genitive case, meaning “contusion.”
