Morphology.

Head: Head densely finely punctate; Vertex slightly punctate. Occiput flat and polished. Temple finely punctate and flat. Mandible very short, upper tooth as long as lower one (Fig. 3C). Minimum distance between eyes 0.6 times as long as maximum distance (Fig. 3B). Ocelli small; diameter of median ocellus 0.8 times as long as distance between ocellus and eye; lateral ocellus separated from eye by 1.6 times of lateral ocellus diameter. Antenna with 32 flagellomeres, 1st flagellomere 1.5 times as long as 2nd flagellomere.

Mesosoma: Pronotum sparsely punctate; upper part reticulate; ventrally with transverse striae (Fig. 3D); epomia absent. Mesoscutum closely and finely punctate; notaulus absent (Fig. 3F). Mesopleuron reticulate; postpectal carinae complete; epicnemial carina reaching anterior margin of mesopleuron at its middle (Fig. 3E); epicnemial carina present; sternaulus absent. Scutellum closely punctate; postscutellum flat, broader than high. Propodeum reticulated; basal area and areola not separated by anterior transverse carina; costula present but incomplete (Fig. 5J); areola and petiolar area not separated, impressed (Fig. 3H); spiracle round; connected to pleural carina; distance between spiracle and pleural carina 0.7 times as long as diameter of spiracle (Fig. 3I). Hind tibia with short spines; ratio between hind tarsal segments 5.1: 2.4: 1.6: 0.9: 1.0. Fore wing with areolet (Fig. 3L); basal vein opposite nervulus; nervellus not intercepted; discoidella absent.

Metasoma: Thyridium separated from base of 2nd tergite by more than 3.0 times its diameter; distance between base of 2nd tergite and thyridium 0.5 times as long as distance between base of 2nd tergite and spiracle (Fig. 3K). 6th and 7th tergites deeply emarginate apically (Fig. 3N). Ovipositor (Fig. 3G) 1.6 times as long as hind tibia.

Male. Unknown.

Distribution.

Korea.

Etymology.

The specific name is derived from the locality of the type specimens.

Comments.

This species is similar to Cymodusa aenigma Dbar, 1985, but the areolet is not sessile and the basal 1st to 3rd flagellomeres are yellow below (as in Cymodusa leucocera Holmgren and Cymodusa distincta Cresson).
