Morphology.

Head: Head closely and finely punctate. Vertex slightly punctate. Occiput flat and polished. Temple finely punctate and flat. Mandibles short, upper tooth as long as lower one. Minimum distance between eyes 0.6 times as long as maximum distance (Fig. 4C). Ocelli small; diameter of median ocellus 0.9 times as long as distance between ocellus and eye; lateral ocellus separated from eye by 1.0 times lateral ocellus diameter. Antenna with 31 flagellomeres, 1st flagellomere 1.3 times as long as 2nd flagellomere.

Mesosoma: Pronotum sparsely punctate; upper part reticulated; lower part with transverse striae; epomia absent. Mesoscutum closely and finely punctate; notaulus absent (Fig. 4G). Mesopleuron reticulate (Fig. 4F); postpectal carinae complete; epicnemial carina present; sternaulus absent. Scutellum closely punctate; postscutellum flat, broader than high. Propodeum reticulate; basal area and areola separated by anterior transverse carina (Fig. 5K); costula weak; areola and petiolar area not separated, impressed; spiracle small, round; distance between spiracle and pleural carina 1.00 times diameter of spiracle (Fig. 4I). Hind tibia with short spines; ratio between hind tarsal segments 4.4: 2.0: 1.3: 0.7: 0.9. Fore wing with areolet; basal vein opposite nervulus (Fig. 4M); nervellus not intercepted; discoidella absent.

Metasoma: Thyridium separated from base of 2nd tergite by more than 4.0 times its diameter; distance between base of 2nd tergite and thyridium 0.6 times as long as distance between base of 2nd tergite and spiracle (Fig. 4L). 6th and 7th terga deeply emarginate apically (Fig. 4N); 7th tergite longer than 6th tergite (Fig. 6H). Ovipositor (Fig. 4K) shorter than metasoma, 1.7 times as long as hind tibia.

Male. Unknown.

Distribution.

Korea.

Etymology.

The species is named after the nickname of Dr. Jong-Wook Lee, who collected the type specimens.

Comments.

This species is similar to Cymodusa oculator Dbar (1985) but differs by the number of flagellar segments, developed clypeal fovea, basal area and areola not separated, and a different color pattern.
