Description. FEMALE. Length 3.2 mm. Body green-bronze with violet tint on posterior parts of notauli and on lower face; gaster brownish; legs (including tarsi) and antennae dark metallic ( Figs 1–3 View FIGURE 1 View FIGURE 2 View FIGURE 3 ). Fore wing widely darkened, veins of wings dark brown ( Figs 1A‒C View FIGURE 1 ).
Head in dorsal view about 2.2× as wide as long; POL nearly 2.0× OOL, and OOL about 2.3× MDO. Head in frontal view ( Figs 2B View FIGURE 2 , 3G View FIGURE 3 ) about 1.4× as wide as high; toruli with ventral margins situated 1/2 diameter of torulus above virtual line connecting lower margins of eyes ( Fig. 2B View FIGURE 2 ). Face faintly reticulate, with area above clypeus smooth ( Fig. 2C View FIGURE 2 ). Eyes with inner margins subparallel ( Fig. 2B View FIGURE 2 ). Gena evenly curved ( Fig. 2C View FIGURE 2 ). Malar sulcus complete ( Figs 2B‒D View FIGURE 2 ). Mouth opening about 1.8× as wide as malar space. Anterior margin of clypeus and labrum both with four setae ( Fig. 2C View FIGURE 2 ). Antenna ( Fig. 2E View FIGURE 2 ) with scape about 3.5× as long as wide; pedicel about 2.0× as long as wide; an1 very thin, strongly transverse; an2 1.7× as wide as long, and about 3.0× shorter and 1.5× narrower than F1; F1–F4 about 1.3× as long as wide; club about 2.8× as long as wide and 2.6× as long as F4, with segments separated by sutures and deep constrictions, and terminal spine long, about ¼ length of club.
Mesosoma about 1.5× as long as wide, shallowly reticulate ( Fig. 2A View FIGURE 2 ). Pronotum in dorsal view ( Figs 2A View FIGURE 2 , 3G View FIGURE 3 ) short, conical, its collar present as a narrow strip, collum short, evenly sloping ( Figs 1B View FIGURE 1 , 3G View FIGURE 3 ). Mesoscutum ( Fig. 2A View FIGURE 2 ) nearly 2.0× as wide as long; mesoscutellum slightly longer than wide and slightly longer than mesoscutum, its surface alutaceous except its extreme margin smoother ( Fig. 2A View FIGURE 2 ). Axilla with 3 bristles. Mesopleuron with deep femoral depression and straight, sulcate transepimeral sulcus ( Figs 3A, C View FIGURE 3 ). Metanotum wide, with metascutellum about 0.35× (1/3) as long as mesoscutellum ( Figs 1D, E View FIGURE 1 , 2A View FIGURE 2 ). Metapleuron subrectangular, coarsely reticulate. Fore wing approximately 2.0× as long as wide, slightly longer than body ( Figs 1A–C View FIGURE 1 ); subcosta of SMV broken at juncture with parastigma, with 5 dorsal bristles; MV about 1.4× as long as costal cell and about 0.7× wing width; STV with long petiole, drop-shaped stigma, and relatively long uncus; PMV about 1.3× as long as STV; marginal fringe short, about 0.5× as long as STV and about 1.5× as long as width of MV at its widest part. Calcar about as long as width of fore tibia ( Fig. 3D View FIGURE 3 ); midtibial spur about 2.0× as long as width of mid tibia; hindtibial spur about as long as width of hind tibia ( Figs 3C–F View FIGURE 3 ). Propodeum ( Figs 1D, E View FIGURE 1 ) coriaceous-reticulate, its submedian areas elevated, with robust median carina which fades posteriorly and with wide supracoxal flange bearing septae; propodeal callus with 12 setae.
Metasoma as long as mesosoma ( Figs 1A–C View FIGURE 1 ); petiole transverse, reduced. Gaster in dorsal view about 1.5× as long as wide ( Fig. 1C View FIGURE 1 ); Gt 1 with slightly elevated anterior areas bearing about 10 sparse setae; posterior margin of tergites straight ( Fig. 3B View FIGURE 3 ) and with bristles starting from Gt 3 ( Fig. 3B View FIGURE 3 ); syntergum (Gt 7) with a membranous lobe apically, with cercus short and with 3 setae.
