DESCRIPTION. FEMALE. Body length 4.1–4.5 mm; fore wing length 2.9–3.0 mm.

Head and mesosoma black. Antenna with scape, pedicel and anelli yellowish-brown; flagellum dark brown; clava with C1–C4 dark brown, but micropilosity area yellowish-brown. All coxae black; all femora yellowish-brown; tibiae, and tarsi yellow. Fore wing hyaline, venation yellowish-brown. Metasoma with Mt2 basally brown, apically yellow, Mt2 brown, Mt3-Mt7 dark metallic green with diffuse coppery lustre, Mt8 dark brown.

Head and mesosoma reticulate; clypeus radially striate; propodeum finely reticulate; metasoma alutaceous and shiny.

Head in dorsal view 2.10–2.22 times as broad as long and 1.11–1.14 times as broad as mesoscutum; in frontal view 1.23–1.28 times as broad as high. POL 1.06– 1.10 times as long as OOL. Eye height 1.47–1.52 times eye length and 2.10–2.26 times as long as malar space. Distance between antennal toruli and lower margin of clypeus 1.16 times distance between antennal toruli and median ocellus. Lower margin of clypeus with angulate median tooth. Antenna with scape 0.57–0.60 times as long as eye height and 0.88 times as long as eye length; pedicel 1.56–1.68 times as long as broad and 1.00–1.10 times as long as F1; combined length of pedicel and flagellum 0.72–0.75 times breadth of head; F1 1.15–1.20 times as long as broad and with 1 row of sensilla, F2–F6 wider than length; clava 2.33–2.44 times as long as broad and 1.30–1.41 longer than combined length of F4–F6; micropilosity area on C1–C4.

Mesosoma 1.26–1.29 times as long as broad. Scutellum 0.96–0.98 times as long as broad. Propodeum 3.0 as long as broad; with nucha, strong median carina and plicae, median area depressed; 0.55–0.56 times as long as scutellum. Fore wing 2.40–2.48 times as long as maximum width; basal cell bare, basal vein pilose; speculum partly open; M 1.30–1.35 times as long as P and 3.30–3.35 times as long as S.

Metasoma lanceolate, 73.00–3.40 times as long as broad, 1.35–1.50 times as long as mesosoma and 1.07–1.15 times as long as combined length of mesosoma and head.

MALE. Unknown.

DISTRIBUTION. South Korea.

BIOLOGY. Unknown.

ETYMOLOGY. From the Latin robusta , referring to the robust mesosoma of the described species.

DIAGNOSIS. Uniclypea robusta sp. n. is similar to U. kumarani in having an occipital carina, a median carina on the propodeum, strong plicae and depressed median area, and a metasoma 2.8–3.4 times as long as broad, approximately equal to the combined length of the mesosoma and head. However, females of Uniclypea robusta sp. n. differ in having a POL 1.06–1.10 times as long as OOL (vs 1.50 x in U. kumarani ); a propodeum with strong median carina (vs weak) and antenna with F1–F6 dark brown (vs testaceous).
