Type material.

Holotype: female, "Japan, Shikoku Isl., Muroto, Tosa, 8.VI.1959, M. Miyatake" (ZISP). Paratype: 1 female, "Japan, Shikoku Isl., Kuroson, Tosa, 30.IV.1956, M. Miyatake" (EUM).

Description.

Female. Body length 5.00-5.20 mm; fore wing length 3.90-4.10 mm.

Coloration. Head dark brown. Antenna with scape yellowish-brown; pedicel, and flagellum brown. Mesosoma cupreous in lateral view with diffuse violet lustre. All coxae brown with diffuse violet lustre; all femora, tibiae, and tarsi yellowish-brown. Fore wing slightly infuscate; venation yellowish-brown. Metasoma cupreous.

Sculpture. Head in frontal view weakly reticulate, in dorsal view and clypeus smooth and shiny; mesosoma reticulate, but axilla and frenum alutaceous; dorsellum shiny, without upper crenulate cross-line, and with lower crenulate cross-line; propodeum weakly reticulate; propodeum weakly reticulate propodeum weakly alutaceous; metasoma weakly alutaceous and shiny.

Head. Head in dorsal view 2.10-2.17 times as broad as long and 1.66-1.69 times as broad as mesoscutum; in frontal view 1.30-1.34 times as broad as high. POL 0.77-0.80 times as long as OOL. Eye height 1.27-1.33 times eye length and 2.90-3.20 times as long as malar space. Distance between antennal toruli and lower margin of clypeus 0.85-0.97 times distance between antennal toruli and median ocellus. Lower margin of clypeus weakly emarginate. Antenna with scape 0.67-0.73 times as long as eye height and 0.89-0.90 times as long as eye length; pedicel 1.40-1.53 times as long as broad and 0.40-0.45 times as long as F1; combined length of pedicel and flagellum 1.56-1.57 times breadth of head; F1 2.95-3.00 times as long as broad and with 3 rows of sensilla, F3-F6 longer than broad; clava 2.30-2.50 times as long as broad, with micropilosity area on C3 and C2.

Mesosoma. Mesosoma 2.00-2.10 times as long as broad. Scutellum 1.09-1.10 times as long as broad. Propodeum without nucha and costula, 0.85-1.00 times as long as scutellum; medial longitudinal depression shallow, lateral depressions 0.30-0.35 times as long as propodeum. Fore wing 2.79-2.82 times as long as maximum width; basal cell, cubital vein, basal vein pilose; speculum absent; PST 0.62-0.67 times as long as M, M 0.55-0.60 times as long as P and 3.40-3.44 times as long as S.

Metasoma. Metasoma 4.00-4.65 times as long as broad, 1.77-1.95 times as long as mesosoma and 1.32-1.37 times as long as mesosoma and head; Mt8 1.00-1.10 times as long as broad.

Male. Body length 3.00 mm; fore wing length 2.60 mm. Eye height 1.13 times eye length and 3.40 times as long as malar space. Antennal formula 11210; scape 0.62 times as long as eye height and 0.70 times as long as eye length; pedicel 1.10 times as long as broad and 0.26 times as long as F1; combined length of pedicel and flagellum 1.78 times breadth of head; F1 4.67 times as long as broad and with 5 rows of sensilla. Mesosoma 2.00-2.10 times as long as broad. Scutellum 1.09-1.10 times as long as broad. Propodeum without nucha and transversal carina, 0.85-1.00 times as long as scutellum; medial longitudinal depression shallow, lateral depressions 0.30-035 times as long as propodeum. Fore wing 2.79-2.82 times as long as maximum width; basal cell, cubital vein, basal vein pilose; speculum absent; PST 0.62-0.67 times as long as M, M 0.55-0.60 times as long as P and 3.40-3.44 times as long as S. Metasoma 1.33 times as long as mesosoma and as long as mesosoma and head. Otherwise, similar to female.

Etymology.

The species is named in honour of the senior author’s father, Vladimir Tselikh.
