Description of male

Colour: Head and mesosoma: mostly green bronze to green, with metallic lustre; setae on head and mesosoma: generally whitish, inconspicuous, setae on top of head rather fuscous to brown; tegula: yellow to testaceous; setae on callus of propodeum: whitish. Scape: green bronze with metallic lustre; pedicel: green bronze with metallic lustre, slightly darker than scape; flagellum: dark brown to black. Fore wing: hyaline; fore wing venation: lightly testaceous; setae on fore wing: fuscous; hind wing: hyaline. Pro-, meso- and metacoxa: green bronze with metallic lustre; trochanters: dark yellow to testaceous; femora: dark yellow to testaceous, dorsomedially with brown to greenish-bronze colouration with metallic lustre; tibiae: yellow to testaceous; protarsae: fuscous, except anterior first tarsal segment being testaceous; meso- and metatarsae: gradually darkening over segments from light yellow to fuscous. Petiole: dark brown, with green bronze metallic tinge; gaster: uniformly dark brown; gastral terga: with green bronze metallic tinge.

Sculpture: Head in frontal view: reticulate with moderately high septa; clypeus: reticulate; area between clypeus and malar sulcus: reticulation uniform with single areoles elongated radiating from clypeus. Mesoscutum: finely reticulate, meshes moderately low, areoles slightly enlarged medially; mesoscutellum: finely reticulate, mesh equivalent in size to mesoscutum; frenum: engraved reticulation, mesh equivalent in size to mesoscutellum; axilla: finely raised reticulate, as strongly as, but mesh size smaller than in mesoscutellum; prepectus upper triangular area: uniformly reticulate; upper mesepimeron: smooth; upper mesepisternum: reticulate, about as strongly as on mesoscutum; metapleuron: finely reticulate, as strong as mesepisternum. Procoxa: engraved reticulate; mesocoxa: engraved reticulate; metacoxa: raised reticulate dorsally to engraved reticulate ventrally. Median area of propodeum: strongly, irregularly reticulate, about as strong as on mesoscutum, with few higher irregular ridges; inner corner of anterior plica: without depression; nucha: not enlarged, presented as a fine rather smooth strip; callus of propodeum: irregularly reticulate, but less strong than median area of propodeum, even partly smooth; paraspiracular sulcus: coarse rugae, continuing from median propodeal area, reticulation hardly present. Petiole in dorsal view: smooth; gastral terga: smooth and shining, from second tergum alutaceous.

Shape and structure: Head in frontal view: round; gena in frontal view: slightly curving; temple in dorsal view: obtuse; occipital carina: absent; torulus position with respect to lower ocular line: distinctly above; lower face in lateral view: slightly rounded, with slight bulge on lower face below toruli; receding with respect to upper face: weakly; scrobe: narrow and shallow; malar sulcus: developed, moderately deep; clypeus anterior margin: three asymmetric teeth, with single tooth on the right, inner left tooth larger than other two; tentorial pit: indistinct; mouth extension: moderate; mandibular formula: not assessable. Antenna: Antennal formula: 11263; scape reaching: hardly median ocellus; flagellum: filiform; first anellus: strongly transverse; second anellus: strongly transverse; first funicular segment: conical, elongate; following funicular segements: conical, elongate; setae on flagellum: fairly thickly clothed with forward pointed erect setae, length of setae hardly as long as breadth of flagellar segments; number of rows of longitudinal sensilla on first funicular segment: 3 - 4 irregular; on sixth: 2 - 3 irregular. Mesosoma in lateral view: moderately bent; propodeum in lateral view slightly angled to mesoscutellum; pronotum breadth with respect to mesoscutum breadth: distinctly narrower; pronotum collar: directly sloping from mesoscutum; its length with respect to mesoscutum length: indiscernible; its anterior margin: not carinate; pronotum posterior margin: forming smooth, shiny strip; notauli: largely superficial, but traceable to hind-margin of mesoscutum; reaching: five sixth along mesoscutum; mesoscutellum in lateral view: slightly arched, especially in posterior third; mesoscutellum in posterior view: rounded; mesoscutellum posterior margin projection: level of anterior margin of metascutellum; mesoscutellum posterior margin in posterior view: appearing ecarinate; frenal line: indicated through row of deeper areoles; prepectus upper triangular area: uniform, but with transverse carina at height of procoxal articulation; upper mesepimeron: almost parallel sides, only tapering at base of mesopleuron; propodeum anterior plica: absent; posterior plica: absent; median carina of propodeum: absent; nucha: reduced to small strip; spiracle: oval, almost round, almost touching anterior margin of propodeum; size: moderate; callus pilosity: thinly pilose; paraspiracular sulcus: steep, angled against median area of propodeum. Forewing: Forewing apex with respect to apex of gaster when folded back: exceeding close to 1/6th its length; basal cell number of setae: few up to 6 distally; basal setal line: incomplete with 3-6 setae; cubital setal line: absent, maximum 3 setae distally; costal cell pilosity on dorsal side: about 6 setae distally; costal setal line: incomplete; speculum on dorsal side: bare, extending close to 1/3rd the length of the marginal vein, widely open below; wing disc: moderately pilose; marginal setae: present, from as long as the length of setae on wing disc on anterior wing margin to about double the length on posterior margin; stigma: oval, small size; uncus: straight, as long as stigma broad. Femora: moderately slender; metatibia: slender, gradually widening towards apex; metacoxa pilosity dorsal: bare. Petiole in dorsal view: subconical; in ventral view: open; gaster in dorsal view: rather club-like, not particularly accuminate; gastral terga: convex, weakly sunken anteriorly; posterior margin of first gastral tergum: emarginate; first gastral tergum reaching: 1/3rd of gaster.
