(Figs 580, 581, 864)
Diagnosis (female). Antennal clava solid (Fig. 864); genal carina present; mesoscutellum (Fig. 580) with median part with strong reticulation and a complete median groove, with submedian grooves curved and diverging towards posterior part; dorsellum with median carina; propodeum (Fig. 580) with strong irregular carinae and strong reticulation, callus with four setae; petiole very short, just a narrow band; gaster (Fig. 580) 3.4× as long as wide, medio-basal Gt1 with a sharp edge shaped like an inverted U (as in Fig. 24), Gt7 2.0× as long as width at base, tergites with strong reticulation.
Female holotype: length of body 2.3mm (paratype 2.1mm).
Scape yellowish-brown, pedicel and flagellum dark brown. Head with frons, including scrobes, and vertex golden-green, clypeus dark brown. Thoracic dorsum golden-green. Legs with coxae golden-green; trochanters dark brown; femora golden-green with apex yellowish-brown; tibiae yellowish-brown; T1–3 yellowish-brown, T4 brown. Petiole black. Gaster with Gt1 with anterior two-thirds metallic bluish-green, posterior one-third and remaining tergites metallic purple; gonoplac black.
Antenna with solid clava. Face below level of toruli with strong reticulation, clypeus smooth, frons rugose, antennal scrobes with weak reticulation; with genal carina. Vertex with strong reticulation outside ocellar triangle, with wrinkled sculpture inside ocellar triangle.
Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe with a median groove in posterior half, with nine scattered adnotaular setae. Mesoscutellum with strong reticulation on median part and with a complete median groove, lateral parts with strong reticulation and with six scattered setae, meshes elongate; submedian grooves distinct, slightly curved and diverging towards posterior part. Dorsellum with weak sculpture and shiny, with median carina. Propodeum with a wide median carina that expands strongly posteriorly; with strong irregular carinae and strong reticulation; callus with four setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with four setae on dorsal surface of submarginal vein; speculum closed; costal setal row broken.
Petiole very short, just a narrow band. Gaster very elongate; medio-basal Gt1 with a sharp edge shaped like an inverted U; tergites with strong reticulation.
