E t y m o l o g y: The species name refers to the black mesoscutum.

D e s c r i p t i o n: ♀: Body length 8.0- 8.2 mm. Flagellum with 38 segments, slender, bristle-shaped; 1 st flagellar segment 4.9× as long as wide, all segments longer than wide. Temple very long, slightly and roundly narrowed behind eye. OED 1.6× and OOD 0.9× ocellar diameter. Temple and frons smooth and shining, with sparse superficial punctures. Face densely punctate, shining. Clypeus flat, with sparse punctures; apical margin sharp and pointed medially. Gena with very sparse punctures. Malar space 0.7× as long as width of mandibular base.

Side of pronotum ± striate posteriorly, epomia long but not reaching ventral margin of pronotum. Notaulus weakly impressed at frontal third of mesoscutum. Mesoscutum coarsely rugose-punctate, with some oblique striae centrally, dull. Mesopleuron striate dorsally and striate-punctate ventrally; speculum smooth. Epicnemial carina not widened ventrally. Sternaulus distinctly impressed in frontal 0.6 of mesopleuron. Metapleuron striated frontally and rugose posteriorly; juxtacoxal carina distinct. Scutellum moderately and roundly elevated, slightly wider than long, coarsely punctate basally, striate apically; lateral carina slightly lamelliform widened, reaching apical 0.7 of scutellum. Postscutellum finely striate. Propodeum rugose-punctate, completely carinated, with short apophysis (shorter than its basal width); spiracle slit-shaped. Area basalis much wider than long, slightly bulging medially. Area superomedia hexagonal, slightly wider than long; costula reaching its middle. Area petiolaris with transverse rugae. Hind coxa densely punctate, without scopa. Hind femur densely punctate, 4.3-4.5× as long as wide. Claws simple. Areolet almost quadrangular, frontal distance between veins 2rs-m and 3rs-m 1× their diameter. Vein 1cu-a interstitial.

Metasoma oxypygous. 2 nd to 4 th sternites with median folds. Postpetiole moderately widened, without latero-median carina, finely rugose-punctate; median field not separated. Gastrocoelus impressed. Thyridium large, slightly oblique, 2.0× as wide as interval between thyridia. 2 nd tergite 1.2× as wide as long. 2 nd tergite densely rugose-punctate, with superficial structure in apical 1/4. 3 rd tergite with dense superficial punctures; following tergites finely granulate and ± shining. Ovipositor sheath slender and stick-shaped, reaching behind metasomal apex by length of 3 rd hind tarsomere.

Color: black. Flagellum black, flagellar segment 7-14 ivory dorsally. Palps, mandible except teeth, clypeus, face except small brown median spot, small apical spot on ventral scape, gena and complete orbits except narrow interruption on vertex, frontal and upper margins of pronotum, tegula, subtegular ridge, wide stripe of ventral mesopleuron, scutellum and postscutellum, upper division and apical spot on metapleuron, posterolateral stripes on propodeum, petiole mainly, and apical bands of all tergites (medially ± narrowed) ivory. Legs reddish; fore and mid coxae and trochanters ivory; hind coxa black, with ivory dorsal spot; hind femur apically and hind tibia basally and apically infuscate; fore and mid tarsi brown; hind tarsus except brown base of metatarsus and brown distal tarsomere ivory. Wings hyaline; pterostigma reddish or brown.

³. Body length 10.5 mm. Flagellum with 40 segments, long and bristle-shaped; 1 st flagellar segment 3.2× as long as wide. Tyloids on flagellar segments 11-21, long-oval, small, maximally 0.3× as long as their segments. OED 1.8× and OOD 1.4× ocellar diameter. Area superomedia 1.3× as wide as long. Apophysis about as long as basally wide. Hind femur 4.0× as long as wide. Areolet pointed frontally. 2 nd tergite 1.2× as wide as long. Apical margin of hypopygium moderately elongate medially. Structure otherwise as described for the ♀.

Color: Flagellar segments 11-20 ivory dorsally. Face entirely ivory. Mesoscutum without paramedian ivory stripes. Postpetiole with posterolateral yellow spots; 2 nd to 5 th tergites with apical yellow bands (interrupted medially at 5 th tergite); 6 th tergite black; 7 th tergite with wide apical ivory band. Hind tibia yellowish, black in basal 0.15. Hind tarsus including distal tarsomere ivory. Color otherwise as described for the ♀.
