(
Figs 39–42
,

)
Diagnosis.
Frons with an interscrobal procession (
Fig. 39
); frontal suture reaching eyes below anterior ocellus at a level equal to 1.5X diameter of an ocellus (
Fig. 39
); propodeum with median carina, plicae and costulae (
Fig. 41
), and callus with 6 setae; forewing costal cell ventrally with a sparse row of setae in apical ½ (as in
Fig. 51
); petiole as long as wide.
Description.
FEMALE. Length
1.9 mm
. Scape pale brown with dorsal edge dark brown, pedicel and flagellum dark brown. Frons below frontal suture metallic bluish-green, above frontal suture metallic bluish-purple. Vertex inside ocellar triangle golden-green, outside ocellar triangle metallic bluish-purple. Mesoscutum with anterior 1/3 metallic dark purple, posterior 2/3 metallic bluish-green. Scutellum with anterior ½ golden-purple, posterior ½ metallic bluish-green. Propodeum metallic bluish-green. Coxae, femora and tibiae dark and metallic; tarsi with tarsomeres 1–3 white, 4 dark brown. Forewing hyaline. Gaster with tergite 1 metallic bluish-purple, remaining tergites golden-purple.
Antenna as in
Fig. 68
. Frons with raised, weak reticulation below level of toruli except smooth just below toruli and close to mouth margin above mandibles, parts up to frontal suture with raised, strong reticulation, and smooth above frontal suture (
Fig. 39
); frontal suture reaching eyes below anterior ocellus at a level equal to 1.5X diameter of an ocellus. Vertex with engraved, strong reticulation inside ocellar triangle, but smooth outside ocellar triangle (
Fig. 42
). Occipital margin rounded. Eyes with sparse, scattered hairs (
Figs 39, 42
).
