Description. Body length: 2.5 mm. Colouration: Head metallic bluish green with strong cupreous reflection in particular beyond posterior ocelli; antennae brown, scape and pedicel darker; mandible brown with faint metallic tint basally; thorax and metasoma metallic cupreous, pronotum with greenish tint and blackish anterior declivity; T2 apical rim nonmetallic light brown, hyaline; metasomal sterna and legs brown, coxae and femora darker; wings hyaline. Body with extremely short sparse erect to decumbent silvery setae.

Head: In dorsal view, wider than pronotum, narrowed and gently rounded behind eyes, slightly concave in rear; vertex and brow moderately reticulate-punctate; POD 1.36 OOD; mid ocellus not lidded; brow without TFC; face fairly broad, least interocular distance as long as eye height; scapal basin shallowly concave, broadly cross-ridged; subantennal space as wide as MOD; malar space 0.4 MOD long; clypeus bald, polished (impunctate), slightly convex in the disc, with apical margin straight; genae distinctly narrow; genal carina weak, contiguous to outer ocular margin; mandible with a small subapical tooth. F1 2× as long as broad, 1.25× as long as pedicel, 1.6× as long as F2 and F3.

Mesosoma: Pronotum in greater anterior part, scutellum laterally, metanotum and upper surface of mesopleuron moderately reticulate-punctate; punctures subreticulate elsewhere. Pronotum gently declivitous in front, with humeral part broadly rounded; mesoscutum with complete notuli divergent in front, with distinct parapsidal lines; tegula ovoid, normal-sized, fairly shallowly punctate; metanotum evenly convex; propodeum vertical (invisible in dorsal view); propodeal lateral angle slender and digitate, pointed to backward, strongly concave posteriorly, adjacent to metanotum; mesopleuron moderately angulate ventrally. Tarsal claws edentate, hind tibiae with dark drop-shaped spot occupying more than apical third of inner surface. Fore wing with three closed cells: costal, radial and cubital cells; M vein faintly bent, arising slightly after cu-a; Rs about 0.75× as long as stigma; no evidence of Rs+M, Cu and R1; stigma wellsclerotised; prestigma swollen.

Metasoma: Terga finely subreticulate-punctate, punctures on T2 rather sparse posteriorly; T1 markedly short, abruptly declivitous anteriorly, evenly rounded antero-laterally; T2 distinctly long, about 8.3× as long as T1 along midline, obtusely angulated apico-laterally, with apical rim hyaline, without pit row and evenly rounded (edentate); sterna polished and strongly concave.
