Description.

Female. Body length 1.70–2.10 mm; fore wing length 1.60–1.70 mm.

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

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

Head. In dorsal view 2.23–2.43 × as broad as long and 1.35–1.46 × as broad as mesoscutum; in frontal view 1.57–1.67 × as broad as high. POL 0.54–0.60 × as long as OOL. Eye height 1.12–1.15 × eye length and 1.50–1.63 × malar space. Distance between antennal toruli and lower margin of clypeus 3.35–4.60 × distance between antennal toruli and median ocellus. Antenna with scape 0.94–1.03 × as long as eye height and 1.06–1.19 × as long as eye length; pedicel 1.12–1.45 × as long as broad; combined length of pedicel and flagellum 0.72–0.83 × breadth of head; F 1 – F 6 longer than broad, F 1 1.64–1.83 × as long as broad and with two rows of sensilla; clava 2.46–2.67 × as long as broad, with small microsetose area on C 3 and C 4. Lower posterior corner of gena with small sharp spine. Lower margin of clypeus concave bilaterally, in middle part distinctly emarginate.

Mesosoma. 1.14–1.16 × as long as broad. Scutellum moderately arched, 0.83 × as long as broad, frenal area differentiated by a change in sculpture. Propodeum 0.72–0.75 × as long as scutellum, without costula but with median carina, nucha small. Fore wing 2.20–2.24 × as long as its maximum width; basal cell with 0–3 setae, basal vein setose; speculum closed below; M 0.67–0.73 × as long as PM and 1.17–1.22 × as long as S, stigma large.

Metasoma. 1.60–1.80 × as long as broad, 0.70–1.12 × as long as mesosoma, 0.53–0.80 × as long as mesosoma and head. Petiole 1.00–1.50 × as long as broad. Ovipositor sheaths projecting slightly beyond apex of metasoma.

Male. Body length 1.70 mm; fore wing length 1.58 mm. Antenna thicker than in female; gaster short and compressed. Otherwise, similar to female ( Sureshan and Narendran 2002).

Biology.

Egg parasitoids of hemipterans of the family Pentatomidae ( Sureshan and Narendran 2002) .

Distribution.

India ( Sureshan and Narendran 2002).

Comments.

Acroclisoides maculatus Sureshan & Narendran belongs to a group of species where females have a fore wing with one spot. This species is similar to A. megacephalus Girault & Dodd ; the differences between these species are given in the key.

The material from India was misidentified as A. indicus Ferrière by Bouček (see Material examined above). Here this material is regarded as A. maculatus Sureshan & Narendran.
