Description.

Female. Body length 2.40 mm; fore wing length 2.65 mm.

Coloration. Head and mesosoma dorsally dark blue with diffuse metallic violet luster; head frontally dark green with diffuse coppery luster; antenna with scape, pedicel and anelli yellow, F 1 – F 6 and clava brown. Fore and hind coxae basally brown with metallic blue luster, apically yellowish brown, 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 and violet luster; ovipositor sheaths brown.

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

Head. In dorsal view 2.52–2.95 × as broad as long and 1.51–1.56 × as broad as mesoscutum; in frontal view 1.67–1.68 × as broad as high. POL 0.81–0.82 × as long as OOL. Eye height 1.13–1.17 × eye length and 1.54–1.78 × malar space. Distance between antennal toruli and lower margin of clypeus 2.00–2.30 × distance between antennal toruli and median ocellus. Antenna with scape 0.75–0.76 × as long as eye height and 0.87–0.89 × as long as eye length; pedicel 1.20–1.25 × as long as broad; combined length of pedicel and flagellum 0.91–0.92 × breadth of head; F 1 – F 6 longer than broad, F 1 1.60–1.80 × as long as broad and with one or two rows of sensilla; clava 2.53–3.40 × 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 shallowly concave bilaterally, in middle part weakly emarginate.

Mesosoma. 1.34–1.40 × as long as broad. Scutellum moderately arched, 0.83–0.85 × as long as broad, frenal area differentiated by a change in sculpture. Propodeum 0.70–0.73 × as long as scutellum, without costula or median carina, nucha small. Fore wing 1.95–2.00 × as long as its maximum width; basal cell and basal vein setose; speculum small and closed below; M 0.68–0.83 × as long as PM and 0.85–1.00 × as long as S, stigma large.

Metasoma. 1.48–1.55 × as long as broad, 0.92–0.93 × as long as mesosoma, 0.65–0.70 × 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 1.50–1.65 mm; fore wing length 1.45–1.60 mm. Combined length of pedicel and flagellum 0.98–1.10 × breadth of head. Fore wing with M 0.95–1.05 × as long as PM. Metasoma 1.85–2.08 × as long as broad. Otherwise, similar to female.

Biology.

Egg parasitoids of the hemipteran Acanthosoma sp. ( Acanthosomatidae ) ( Dzhanokmen 1982).

Distribution.

Republic of Korea, Russian Far East ( Dzhanokmen 1982; Lee et al. 2019).

Comments.

Acroclisoides emeljanovi (Dzhanokmen) belongs to a group of species where females have a fore wing with one spot. This species is similar to A. spilopterus (Masi) , A. supramaculatus Tselikh , sp. nov. and A. miklukhai Tselikh , sp. nov.; the differences between these species are given in the key.
