Morphology
Head: Head finely and densely punctate. Occiput flat and polished. Temple broad and convex, finely punctate. Mandible very short, upper tooth as long as lower tooth (Fig. 2C). Minimum distance between eyes 0.6 times as long as maximum distance (Fig. 2B). Ocelli small; diameter of median ocellus 0.9 times as long as distance between ocellus and eye; lateral ocellus separated from eye by 1.3 times of lateral ocellus diameter. Antenna with 31–32 flagellomeres, 1st flagellomere 1.3 times as long as 2nd flagellomere.
Mesosoma: Pronotum with transverse striae ventrally (Fig. 2D); epomia weak. Mesoscutum finely and densely punctate; notaulus absent (Fig. 2F). Mesopleuron roughly punctate, reticulate; postpectal carinae complete, epicnemial carina short; sternaulus absent. Scutellum finely punctate; postscutellum broader than high. Propodeum with numerous transverse rugae and reticulate; basal area and areola separated by anterior transverse carina; costula absent (Fig. 5I); areola and petiolar area not separated, impressed medially (Fig. 2G); spiracle small, round, connected to pleural carina, distance between spiracle and pleural carina 0.9 times as long as diameter of spiracle (Fig. 2H). Hind tibia with short spines; ratio between hind tarsal segments 5.0: 2.2: 1.5: 0.9: 0.9. Fore wing with areolet; basal vein opposite nervulus; nervellus not intercepted; discoidella absent (Fig. 2L).
Metasoma: Thyridium small, oval; separated from base of 2nd tergite by more than 2.0 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. 2K). 6th and 7th tergites deeply emarginate apically (Fig. 2M). Ovipositor 1.5 times as long as hind tibia (Fig. 2J).
Male. Unknown.
Distribution
Korea.
Etymology
The specific name is derived from Korea, the locality of the type specimens.
Comments
This species is similar to Cymodusa rufiventris Dbar, 1985 in the structure of the propodeum and costula, but the basal area is different, areolet is sessile and pentagonal, and the metasoma is darker.
