(Figs 644, 645, 1104)
Diagnosis (female). Antenna with solid clava (Fig. 1104); clypeus yellowish-brown; large frontal orifices as elongate pale non-metallic stripes reaching from just below and lateral of toruli down to clypeus (as in Fig. 904), genal carina absent; frons and midlobe of mesoscutum with large pits around attachment points of setae (Fig. 644); mesoscutellum (Fig. 644) with submedian grooves parallel, strong and distinct, median part with weak reticulation, meshes elongate; dorsellum with median carina; propodeum (Fig. 644) with strong reticulation; petiole yellowish-brown, very short; gaster (Fig. 644) 2.5× as long as wide, Gt1 with very weak reticulation, remaining tergites with weak reticulation, gaster hence shiny. Shape of gaster similar to gaster of G. carinifer.
Female holotype: length of body 2.0mm.
Scape yellowish-brown, pedicel and flagellum dark brown. Head with frons metallic bluish-green, antennal scrobes black and clypeus yellowish-brown; vertex black with metallic tinges. Mesosoma metallic bluish-green. Legs with fore and mid coxae dark brown, hind coxa metallic bluish-green; trochanters yellowish-brown; femora dark brown; tibiae and tarsi yellowish-brown. Petiole yellowish-brown. Gaster with Gt1 metallic bluish-purple in anterior two-thirds, dark brown in posterior one-third, Gt2-7 black with metallic purple tinges; gonoplac black.
Antenna with solid clava. Frons with weak reticulation and with pits, each pit with a seta, clypeus and scrobal grooves smooth; without genal carina. Vertex with weak reticulation and with pits with a seta.
Pronotum rugose. Mesoscutum with strong reticulation with small meshes on sidelobes, midlobe rugose and with a strong median groove in posterior half, with ten adnotaular setae in two rows, each seta set in a pit. Mesoscutellum with weak reticulation on median part, lateral parts with strong reticulation, meshes elongate; submedian grooves distinct, straight and parallel; with three setae on lateral parts. Dorsellum with weak sculpture, with median carina. Propodeum with a narrow median carina, with 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; Gt1 with very weak reticulation, almost smooth, remaining tergites with weak reticulation.
