Description
Female. Forewing 4.3 mm, body about 5.1 mm long.
Colour. Black. Scape from below, face and clypeus entirely, mandible, palpi, malar space, temple widely, frons except space between ocelli, upper third of pronotum, two spots on the notauli, a large spot behind middle of mesoscutum, scutellum and postscutellm, tegula, subtegular ridge, large longitudinal spot below it, upper 0.25 of metapleuron, pleural area of propodeum, area dentipara of propodeum and legs, except base of hind coxa and trochanter bright yellow; hind tarsal segments red orange; flagellum from below light brown.
Head. Strongly narrowed behind eyes. Antenna with 24 flagellomeres, short. First flagellomere only 1.5 times as long as wide, most segments transverse. Frons concave above antennal sockets, prominent in the middle as a process, with longitudinal carina from tip of the process to median ocellus. The distance from the frons process to interantennal process 0.5 times as long as ocellus diameter. The distance between lateral ocellus and eye 1.2 times as long as lateral ocellus diameter. Temple shorter than transverse diameter of eye (13: 17). Occipital carina developed dorsally and laterally, absent below lower level of eye. Hypostomal carina well developed. Face square, not separated from clypeus, very densely and coarsely punctured, the distance between points much shorter than their diameter. Clypeus apically not punctured. Front tentorial pits distinct. Malar space as long as basal width of mandible. Lower tooth of mandible shorter than upper tooth.
Mesosoma . Epomia present, notaulus deep and long, extending to middle of mesoscutum, scutellum flat. Prepectal carina reaching subtegular ridge. Mesopleuron strongly convex below subtegular ridge. Sternaulus weak on front third of mesopleuron. Body covered with silver hairs, metapleuron and lower two-thirds of propleurum without setae, lustrous. Radial RS vein originated from middle of pterostigma. Vein Rs+M strongly curved. Vein Cu-a postfurcal as about 0.5 of its length. Hindwing with seven distal hamuli. Vein cu-a of hindwing distinctly inclivous, intercepted in lower third, vein Cu1 of hindwing faint. Legs very stout, hind femur 1.9 times as long as wide. Front spur of mid tibia 0.5 times as long as hind spur. Ratio between hind tarsal segments as 22: 11: 9: 7: 13. Tarsal claws simple. Propodeum with transverse area superomedia ( Figure 6c View Figure 6 ). The carina separated area basalis and area superomedia interrupted in the middle. Apical transverse carina developed between area petiolaris and lateral/pleural area but absent between area superomedia and area petiolaris. Costula absent. Propodeal spiracle 2.0 times as long as wide, situated at equal distance from both lateral longitudinal and pleural carinae. Justacoxal carina very strong, prominent in front as a powerful blunt tooth.
Metasoma. Densely and finely punctate. Median longitudinal carinae extending on basal 0.45 of tergite 1. Tergite 2 0.8 times as long as wide apically. Epipleuron of tergite 3 wedge-shaped, basal half of the edge straight. Ovipositor sheath not surpassing tip of metasoma.
Male. Unknown.
Etymology
From transverse area superomedia (=areola) of propodeum.
Distribution
South Korea.
Remarks
The species is close to Exochus pictus Holmgren, 1858 and Exochus ru fi gaster Kusigemati, 1971, but differs by its developed above occipital carina, short flagellum and reduced number of flagellomeres, shorter first flagellomere, transverse area superomedia of propodeum, not developed costula, longer forespur of mid tibia, very stout legs and colour pattern.
