DESCRIPTION. FEMALE. Body length 4.00– 5.30 mm; fore wing length 2.80– 3.50 mm.

Head metallic bluish-green with diffuse coppery lustre; antenna with scape yellowish-brown; pedicel and flagellum dark brown. Mesosoma including propodeum metallic bluish-green with diffuse coppery lustre. All coxa metallic bluish-green; all femora brown; all tibiae and tarsi yellowish-brown. Fore wing with long fuscous cloud below stigmal vein, venation yellowish-brown. Metasoma with Mt2 basally metallic blue with diffuse coppery lustre, apically dark brown, Mt3-Mt6 dark brown.

Head reticulate; clypeus smooth and shiny. Mesosoma reticulate, but scutellum finely reticulate; dorsellum and propodeum alutaceous; upper mesepimeron with lower part alutaceous, upper part smooth; metapleuron reticulate. Metasoma weakly alutaceous and shiny.

Head in dorsal view 2.19–2.20 times as broad as long and 1.35–1.37 times as broad as mesoscutum; in frontal view 1.24–1.26 times broader than high. POL 0.90–0.93 times OOL. Eye height 1.40–1.42 times eye length and 2.55 times as long as malar space. Distance between antennal toruli and lower margin of clypeus 0.66–0.68 times distance between antennal toruli and median ocellus. Antenna with scape 0.75–0.78 times as long as eye height and 1.05–1.10 times as long as eye length; pedicel 2.00–2.16 times as long as broad and 0.58–0.60 times as long as F1; combined length of pedicel and flagellum 1.41–1.43 times breadth of head; flagellum almost filiform; all anelli transverse; F1–F6 longer than broad; F1 with 3-4 rows of sensilla; clava 2.90–3.06 times as long as broad and shorter than F5-F6, with large micropilosity area on C2–C4.

Mesosoma 1.67–1.70 times as long as broad. Scutellum 1.09–1.12 times as long as broad, frenal area distinct. Propodeum without nucha, 0.32–0.33 times as long as scutellum; median carina present.

MALE. Unknown.

DIAGNOSIS. Plutothrix skywalkeri sp. n. belong to a group of species that have a fore wing with long fuscous cloud below stigmal vein. This species is very similar to P. yodai sp. n.; the differences between these species are given in the key.

BIOLOGY. Unknown.

DISTRIBUTION. South Korea.

ETYMOLOGY. The species is named in honour of George Lucas' “Star Wars” character – “Anakin Skywalker”.
