Type material.

Holotype, • ♀ ( KSNU), “ South Korea: Gonggeun-ri, Gonggeun, Hoengseong , Gangwon, 19. vii. – 6. viii. 2019, 37°33'58.3"N 127°57'54.9"E, MT [= Malaise trap], Hyojoong Kim leg., KSNU ”.

Diagnosis.

Mesoscutum and scutellum finely punctate and setose (Fig. 29 ); antenna of ♀ with 26 segments; hypoclypeal depression distinct (Fig. 32 ); precoxal sulcus crenulate (Fig. 28 ); antero-dorsal area of mesopleuron brown; medio-posterior depression of mesoscutum present (Fig. 29 ); vein m-cu of fore wing interstitial (Fig. 26 ) or nearly so; first metasomal tergite 0.7 × as long as its apical width (Fig. 30 ) and smooth as following metasomal tergite.

Description.

Holotype, female; length of body 2.4 mm, of fore wing 2.4 mm.

Head. Antenna with 26 segments and as long as body (Fig. 37 ); third segment 2.7 × longer than its width, 1.1 × longer than fourth segment; eye in dorsal view 2.2 × longer than temple (Fig. 33 ); vertex and face shiny, punctate and densely setose; clypeus 2.3 × wider than its maximum height (Fig. 32 ); clypeus in lateral view rather convex with long setae and its ventral margin slightly concave; hypoclypeal depression distinct (Fig. 32 ); maxillary palp 0.7 × as long as height of head; occipital carina interrupted dorsally; mandible triangular and gradually widened basally (Fig. 32 ).

Mesosoma. Mesosoma in lateral view 1.3 × longer than its height; pronope deep, large and round; mesopleuron smooth but precoxal sulcus oblique, robust and crenulate (Fig. 28 ); epicnemial area crenulate ventrally; mesopleural sulcus smooth; anterior groove of metapleuron crenulate; metapleuron area coarsely rugose ventrally with setae and remaining area smooth; notauli absent on disc except deep and short impressions anteriorly (Fig. 29 ); mesoscutum and scutellum shiny, punctate and densely setose; medio-posterior depression of mesoscutum elliptical (Fig. 29 ); scutellar sulcus robust and distinctly crenulate; propodeum reticulate-rugose, with a short medio-longitudinal carina anteriorly and two oblique transverse carinae, remaining area shiny and smooth (Figs 29 , 34 ).

Wings. Fore wing (Fig. 26 ): pterostigma triangular, gradually narrowed apically; veins 1 - M and SR 1 curved; vein 1 - SR 0.3 × as long as vein 1 - M; vein 1 - SR + M sinuate; vein r 0.7 × as long as vein 1 - SR; vein 3 - SR 1.3 × longer than vein 2 - SR; r: 3 - SR: SR 1 = 7: 32: 54; veins m-cu, cu-a interstitial; first subdiscal cell closed. Hind wing (Fig. 27 ): wide; vein m-cu faintly pigmented; vein 1 r-m 0.7 × as long as vein 1 - M.

Legs. Length of hind femur 3.6 × its maximum width (Fig. 36 ).

Metasoma. First tergite 0.7 × as long as its apical width, its surface shiny, smooth and convex medially in lateral view; dorsope absent, dorsal carinae strongly developed and reaching apex of tergite (Figs 29 , 30 ); second metasomal suture absent; second tergite shiny, smooth, with a pair of oblique depressions anteriorly; following tergites shiny, smooth with posterior row of setae; setose part of ovipositor sheath 0.7 × as long as first tergite and 0.09 × as long as fore wing, slightly protruding beyond apex of metasoma (Fig. 35 ).

Colour.

Generally black to dark brown (Fig. 25 ); scape of antenna, mandible and legs yellowish-brown; antenna, face, tegulae and mesopleuron antero-dorsally brown; palpi pale yellowish; veins and pterostigma brown to dark brown; wing membrane subhyaline.

Distribution.

South Korea.

Biology.

Unknown.

Etymology.

Named after the uniformly punctate and setose face, mesoscutum and scutellum; “ punctus ” is Latin for “ point ”, and “ setosus ” is Latin for “ with setae ”.

Remarks.

This new species fits well in the genus Rhogadopsis because of the short medio-longitudinal carina on the propodeum anteriorly, the symmetrical mandible, the complete vein CU 1 b of fore wing, the wide hind wing with less oblique vein 1 r-m of hind wing 0.7 × as long as vein 1 - M and anterior groove of metapleuron crenulated. The species is unique among the East Palaearctic and Northeast Oriental species because of the punctate mesoscutum and scutellum, the smooth first tergite with coarse dorsal carinae up to the apex of the tergite and the lack of vein 2 - SR + M of the fore wing (a result of the subinterstitial vein m-cu).
