Specimens examined
Holotype: female, type depository: YNU; ( South Korea) GW, Hongcheon-gun , Bukbong, Environment Research Park, 15 – 29 June 2009, leg. S.J. Jang.
Description
Female. Forewing 3.6 mm, body 4.3 mm long.
Colour. Black. Upper 0.25 of face, a couple small spots between top of eye and lateral ocelli, palpi, tegula, femora apically, tibiae basally and tarsal segments yellow; flagellum from below, mandible and legs reddish.
Head. Roundly narrowed behind eyes. Frons concave in lower third, with longitudinal carina in concave part. Diameter of ocellus almost as long as distance between eye and lateral ocellus. Antenna with 24 flagellomeres. First flagellomere 2.25 times as long as wide, all segments elongated. Temple shorter than transverse diameter of eye. Face rather strongly convex longitudinally ( Figure 3h View Figure 3 ). Combined face and clypeus 1.3 times as high as wide. Malar space with distinct furrow, almost as long as basal width of mandible. Occipital carina entirely absent.
Mesosoma . 1.6 times as long as high in lateral view. Epomia developed, notaulus deep, extending on front third of mesoscutum. Scutellum and mesopleuron moderately swollen. Prepectal carina strong, reaching subtegular ridge. Sternaulus weak and short. Metapleuron smooth and shining, without any setae. Justacoxal carina lamelliform, almost not widened in front. Vein Rs in forewing originated from middle of pterostigma. Vein Rs+M regularly curved. Vein Cu-a postfurcal at 0.5 of its length. Hindwing with five distal hamuli. Vein cu-a of hindwing intercepted in its lower 0.3, vein Cu1 of hindwing indistinct. Legs moderately stout, hind femur 2.4 times as long as wide. Ratio between length of hind tarsal segments as 25: 11: 9: 6: 10. Tarsal claws simple. Spurs of middle tibia long, front spur 0.5 times as long as hind one. Propodeum fully areolated, costula present ( Figure 6h View Figure 6 ). Area basalis not separated from area superomedia by carina. Area dentipara haired in greater part. Propodeal spiracle 2.0 times as long as wide, much closer to pleural than to lateral longitudinal carina.
Metasoma. Tergite 1 with short median longitudinal carinae, extending on its basal 0.4. Tergite 2 0.75 times as long as wide. Epipleuron of tergite 3 semicircular, the basal threequarters of edge strongly convex. Ovipositor sheath as long as apical depth of metasoma.
Male. Unknown.
Etymology
From entirely absent occipital carina.
Distribution
South Korea.
Remarks
The species is close to Exochus ventralis Holmgren, 1858 , but differs by not widened flagellum and elongated flagellomeres, not widened backward metasoma, more slender legs and coloration of the body.
