Description.

Female. Length of fore wing 10.5-15 mm; body 15-20 mm; ovipositor 18-29 mm. Head and mesosoma with long and dense setae. Malar space about 0.24 times as long as basal width of mandible. Occipital carina interrupted medially. Apical flagellomeres tapered and distal end truncate narrowly. Antenna with 31-32 flagellomeres. Pronotum with strongly impressed and transversely striate groove weakly from epomia to ventroposterior corner; area dorsal to this groove rather strongly and densely punctate, slightly rugose (Fig. 4A ). Mesoscutum in front of scuto-scutellar groove 1.4 times as long as wide in dorsal view (Fig. 4C ); mesopleuron moderately punctate anteriorly, rather sparsely punctated posteriorly, rather densely covered with pubescence; epicnemial carina present ventrally; mesopleural suture transversely striate. Propodeum rugosely punctate, transversely striate dorsomedially, without lateromedian longitudinal carina; posterior transverse carinae strong but incomplete (Fig. 4D ). Hind wing with eight distal hamuli. Fore tibia with four stout spines on dorsal surface and two stout spines on distal end. Hind coxa elongate, 2.8 times as long as maximum width. First metasomal tergite broadened posteriorly in dorsal aspect, 3.1 times as long as posteriorly broad, slightly narrowed a little posterior to spiracle (Fig. 4G ); posterior end of first metasomal sternite at posterior 0.47 between spiracle and posterior end of first metasomal tergite; second to fourth tergites closely covered with weak 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. 4B ). Clypeus yellowish brown. Apical half of mandible black. Frons and vertex black in dorsal view (Fig. 4C ). Upper part of temple black, half of lower part yellowish brown in lateral view (Fig. 4A ). Pronotum and mesoscutum entirely black, without pairs of black longitudinal spots (Fig. 4A ). Mesopleuron black with large reddish brown spot centrally; speculum black (Fig. 4A ); mesosternum black; mesepimeron reddish brown; scutellum and postscutellum black. Propodeum black; metapleuron black, with reddish brown spot below pleural carina. Legs brown to black. Tibia and tarsus paler. Hind coxa to femur black; hind tibia to basitarsus blackish brown; second to fourth hind tarsomeres whitish; fifth tarsomere blackish brown.

Wings hyaline, slightly tinged with brown; pterostigma dark brown, with very weak faint brownish spots around junction of vein R and pterostigma.

Metasomal tergites black. Ovipositor dark brown, sheath black.

Male. Unknown.

Distribution.

South Korea.

Region.

Eastern Palaearctic.

Etymology.

The species is named after Prof. Jong-Wook Lee who collected the holotype specimen and whose collecting efforts have made a great contribution to research into Korean Ichneumonidae .

Remarks.

This new species is similar to R. longissima ( Sheng and Sun 2010), but can be distinguished by the hind coxa to femur black (hind coxa to femur reddish brown in R. longissima ); hind tibia to basitarsus blackish brown; second to fourth hind tarsomeres whitish (yellow in R. longissima ); second metasomal tergite about 1.75 times as long as its apical width (about 3.8 times as long as its apical width in R. longissima ); first metasomal tergite 1.4 times as long as second tergite (first metasomal tergite long, 1.5 times as long as second tergite in R. longissima ).
