(Figs 552, 553, 854)
Diagnosis (female). Antenna with distinct constriction between C1 and C2, flagellum narrow (Fig. 854); genal carina present; mesoscutellum (Fig. 552) rugose throughout and with a complete median groove, submedian grooves with outer margin absent, straight and slightly diverging towards posterior part; dorsellum with median carina; propodeum (Fig. 552) with a mix of irregular carinae and strong reticulation, callus with three setae; gaster (Fig. 552) 2.2× as long as wide, medio-basal Gt1 with a sharp edge shaped like an inverted U (as in Fig. 24), tergites with strong reticulation.
Female holotype: length of body 2.2mm (paratypes 1.8–2.1mm).
Scape yellowish-brown, pedicel and flagellum dark brown. Head with frons black with metallic green and blue tinges, antennal scrobes black and clypeus dark brown; vertex black with metallic blue tinges. Thoracic dorsum metallic bluish-green. Legs with fore and mid coxae dark brown, hind coxa black with metallic tinges; trochanters yellowish-brown; femora dark brown to black with apical one-quarter yellowish-brown; tibiae yellowish-brown; T1–3 yellowish-brown, T4 pale brown. Petiole black. Gaster with Gt 1-2 metallic bluish-green, Gt 3-4 metallic bluish-green on sides, black with purplish tinges medially, Gt5-6 black with purplish tinges, Gt
7 black; gonoplac black.
Antenna with distinct constriction between C1 and C2. 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; with a carina between posterior ocelli in posterior part.
Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe with a very weak median groove in posterior half, with nine scattered adnotaular setae. Mesoscutellum with strong rugosity; submedian grooves with outer margin absent, straight and slightly diverging towards posterior part; with a complete but weak median groove; with nine setae scattered over lateral parts. Dorsellum with strong sculpture, with median carina. Propodeum with a strong and relatively wide median carina that expands posteriorly; with a mix of irregular carinae and strong reticulation; callus with three 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 unbroken.
Petiole very short, just a narrow band. Gaster elongate; medio-basal Gt 1 with a sharp edge shaped like an inverted U; tergites with strong reticulation; longest cercal seta broken off.
