Description.

Female. Body length 1.80–2.10 mm; fore wing length 1.60–1.80 mm.

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

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

Head. Head in dorsal view 2.24–2.37 × as broad as long and 1.35–1.36 × as broad as mesoscutum; in frontal view 1.46–1.56 × as broad as high. POL 0.88–0.92 × as long as OOL. Eye height 1.06–1.10 × eye length and 1.50–1.55 × malar space. Distance between antennal toruli and lower margin of clypeus 1.58–1.80 × distance between antennal toruli and median ocellus. Antenna with scape 0.82–0.88 × as long as eye height and 0.88–0.94 × as long as eye length; pedicel 1.20–1.25 × as long as broad; combined length of pedicel and flagellum 0.73–0.75 × breadth of head; F 1 – F 6 longer than broad, F 1 1.35–1.50 × as long as broad and with 2 rows of sensilla; clava 1.88–2.25 × as long as broad, with small microsetose area on C 3 and C 4. Lower posterior corner of gena with sharp spine. Lower margin of clypeus deeply concave bilaterally, in middle straight.

Mesosoma. Mesosoma 1.23–1.26 × as long as broad. Scutellum moderately arched, 0.83–0, 87 × as long as broad, frenal area differentiated by a change in sculpture. Propodeum 0.63–0.65 × as long as scutellum, without costula and with median carina, nucha small. Fore wing 1, 96–2.12 × as long as its maximum width; basal cell with 0–4 setae, basal vein with 0–7 setae; speculum partly closed below; M 0.62–0.70 × as long as PM and 0.75–0.77 × as long as S, stigma large.

Metasoma. Metasoma 1.61–1.62 × as long as broad, 0.87–0.98 × as long as mesosoma, 0.68–0.72 × as long as mesosoma and head. Petiole 1.00–1.10 × as long as broad. Ovipositor sheaths projecting slightly beyond apex of metasoma.

Male. Body length 1.45–1.60 mm; fore wing length 1.35–1.50 mm. Antenna with scape, pedicel, anelli and F 1 – F 6 yellow; clava with C 1 – C 2 brown, C 3 – C 4 yellow. Metasoma 1.90–1.95 × as long as broad. Otherwise, similar to female.

Biology.

Egg parasitoids of hemipterans Biprorulus bibax Breddin, 1900 , Oechalia consocialis Stål, 1870 and Tectocoris diophthalmus (Thunberg, 1783) ( Pentatomidae ) ( Community UCD 2025).

Distribution.

Australia ( Girault 1924).

Comments.
