Description.

Female. Body length 1.25–1.35 mm; fore wing length 1.20–1.25 mm.

Coloration. Head and mesosoma dorsally dark blue with diffuse metallic luster; head frontally dark blue green with diffuse coppery luster; antenna with scape yellow, pedicel and anelli yellowish brown, F 1 – F 3 and clava brown, F 4 – F 6 yellow or yellowish brown. Fore and hind coxae dark brown with diffuse blue luster, mid coxae yellow, all femora, tibiae and tarsi yellow. Fore wing hyaline, venation brown. Metasoma dorsally dark brown with metallic blue violet luster; ovipositor sheaths brown.

Sculpture. Head and mesosoma reticulate; clypeus reticulate; scutellum reticulate, frenal area finely reticulate; propodeum reticulate, nucha alutaceous; petiole smooth; metasoma smooth and shiny.

Head. In dorsal view 2.04–2.25 × as broad as long and 1.34–1.41 × as broad as mesoscutum; in frontal view 1.47–1.55 × as broad as high. POL 0.74–0.75 × as long as OOL. Eye height 1.10–1.13 × eye length and 1.79–1.83 × malar space. Distance between antennal toruli and lower margin of clypeus 2.20–2.50 × distance between antennal toruli and median ocellus. Antenna with scape 0.85–0.88 × as long as eye height and 0.93–1.00 × as long as eye length; pedicel 1.25 × as long as broad; combined length of pedicel and flagellum 0.95–1.03 × breadth of head; F 1 – F 6 longer than broad, F 1 1.87–2.00 × as long as broad and with one or two rows of sensilla; clava 2.63–2.80 × as long as broad, with small microsetose area on C 3 and C 4. Lower posterior corner of gena forming an acute angle. Lower margin of clypeus concave bilaterally, in middle part emarginate.

Mesosoma. 1.20 × as long as broad. Scutellum moderately arched, 1.23–1.26 × as long as broad, frenal area differentiated by a change in sculpture. Propodeum 0.58–0.65 × as long as scutellum, without costula but with median carina, nucha small. Fore wing 2.08–2.10 × as long as its maximum width; basal cell and basal vein setose; speculum closed below; M 0.75–0.82 × as long as PM and 1.00–1.07 × as long as S, stigma large.

Metasoma. 1.25–1.30 × as long as broad, 0.83–0.88 × as long as mesosoma, 0.60–0.61 × as long as mesosoma and head. Petiole 1.00–1.11 × as long as broad. Ovipositor sheaths projecting slightly beyond apex of metasoma.

Male. Body length 1.20 mm; fore wing length 1.16 mm. Metasoma 1.48 × as long as broad. Otherwise, similar to female.

Biology.

Unknown.

Distribution.

Australia ( Girault 1915), Papua New Guinea (new record).

Comments.
