Description.

Female. Length of fore wing 13-14 mm; body 17-20 mm; ovipositor 22-24 mm. Head and mesosoma with long and dense setae. Malar space about 0.42 times as long as basal width of mandible. Inner orbits slightly converging ventrally (Fig. 3B ). Occipital carina interrupted medially. Apical flagellomeres tapered and distal end truncate narrowly. Antenna with 32-35 flagellomeres. Pronotum with strongly impressed and transversely striate groove from epomia to ventroposterior corner; area dorsal to this groove rather strongly and densely punctate, slightly rugose (Fig. 3A ). Mesoscutum in front of scuto-scutellar groove 1.3 times as long as wide in dorsal view (Fig. 3C ). Mesopleuron densely punctate, rather densely covered with pubescence (Fig. 3A ); epicnemial carina present ventrally; mesopleural suture transversely striate. Propodeum rugosely punctate, transversely striate dorsomedially, without lateromedian longitudinal carina; posterior transverse carinae weak and incomplete (Fig. 3D ). Hind wing with 10 distal hamuli. Fore tibia with 14 stout spines on dorsal surface and three stout spines on distal end. Hind coxa elongate, 2.8 times as long as maximum width. First metasomal tergite broadened posteriorly in dorsal aspect, 3.6 times as long as posteriorly broad (Fig. 3G ); posterior end of first metasomal sternite at posterior 0.33 between spiracle and posterior end of first metasomal tergite; second to fourth tergites densely covered with strongly fine punctures and minute pubescence.

Coloration. Body largely reddish brown to black. Face with narrow yellow stripe, extending along inner orbit to top of eye (Fig. 3B ). Clypeus yellowish brown. Apical half of mandible black. Middle parts on behind of antennal sockets to vertex black in dorsal view (Fig. 3C ). Temple reddish brown (Fig. 3A ). Pronotum black and reddish brown, antero-lateral margin reddish brown (Fig. 3A ). Mesoscutum reddish brown with pairs of longitudinal black spots; median lobe of mesoscutum reddish brown with longitudinal black spots (Fig. 3C ). Mesopleuron reddish brown with black spots on margin of mesopleuron; speculum black; mesosternum black; mesepimeron reddish brown; scutellum dark reddish brown to black; postscutellum yellow, with black spot in the middle. Propodeum black; metapleuron reddish brown, with yellow spot below pleural carina. Legs reddish brown to yellowish brown. Tibia and tarsus paler. Fore coxa with darkened spots ventrally. Mid and hind coxae with darkened spots dorsally. All tarsi yellow except for half of hind basitarsus dark brown. Wings hyaline, slightly tinged with brown; pterostigma black, with faint brownish spots around junction of vein R and pterostigma. Metasomal tergites reddish brown to black. Ovipositor dark brown, sheath black.

Male. Unknown.

Distribution.

South Korea.

Region.

Eastern Palaearctic.

Etymology.

The species name is derived from South Korea, the country of the type specimens.

Remarks.

This new species is similar to R. wooki Choi sp. nov., but can be distinguished from by the second to fourth hind tarsomeres yellow (whitish in R. wooki ); fore tibia with 14 stout spines on dorsal surface and three stout spines on distal end (fore tibia with four stout spines on dorsal surface and two stout spines on distal end in R. wooki ); median lobe of mesoscutum reddish brown with longitudinal black spots, scutellum dark reddish brown to black, postscutellum yellow, with black spot in the middle (mesoscutum entirely black, scutellum and postscutellum black in R. wooki ).
