Mesosoma in lateral view 1.4 times as long as high, polished. Notaulix distinct, subcrenulated, reaching linearform and less deep prescutellar dimple; middle lobe of mesoscutum very finely granulose, otherwise mesoscutum smooth and shiny (Fig. 94). Mesopleuron granulose, precoxal sulcus wide and crenulate. Propodeum rugose, bare, only its latero-posterior part hairy. Metapleuron with rosetteform pubescence. – Hind femur 4.1 times as long as broad distally (Fig. 95). Hind tibia and tarsus equal in length. Hind basitarsus nearly twice as long as second tarsomere.

Fore wing somewhat longer than body. Pterostigma wide, seven times as long as broad, r just longer than width of pterostigma; 1– R 1 one-fifth shorter than length of pterostigma (Fig. 96, see arrows), i.e. 3–SR + SR1 approaching tip of wing. First subdiscal cell closed: CU1b present.

First tergite ( Fig. 104 ) 1.6 times as long as broad behind, evenly broadening posteriorly, pair of spiracles before middle of tergite, pair of basal keels less distinct and meeting medially; rugulose with striate elements. Tergites 2–3 fused, second tergite somewhat longer than third tergite, together with further tergites polished. Ovipositor sheath short, in lateral view as long as second tarsomere of hind tarsus.

Scape and pedicel yellowish brown, flagellum darkening light brown to brown. Head dark brown, temple with faint rusty tint. Mesosoma brownish black. First tergite brown, rest of metasoma reddish yellow, posteriorly with brownish suffusion. Mandible brownish yellow, labrum pale straw yellow. Legs yellow, hind femur brownish yellow, hind tibia and tarsus brown.

Description of the two female paratypes. – Similar to the female holotype. Body 2.8–3 mm long. Antenna with 40 and 42 antennomeres. Hind femur 3.8 times as long as broad distally (1 f, Fig. 97). First tergite 1.5 times as long as broad behind (1 f). Hind coxa basally just brownish.

Description of the male paratype. – Similar to the female types. Body 2.8 mm long. Antenna with 42 antennomeres. Femora 1–2 with weak brownish suffusion.

Host unknown.

Distribution: Korea.

The new species, Chorebus (Stiphrocera) senes , runs to Ch. (St.) coxator (THOMSON) and Ch. (St.) granulosus TOBIAS with the help of TOBIAS’ s keys (1986: 183, 1998: 358). The common feature of the three species is the granulose mesoscutum and mesopleuron. The distinctive features of the three species are as follows:

1.) The distinction of Ch. coxator and Ch. senes :

1 (2) First tergite 1.25–1.3 times as long as broad behind, logitudinally striate, interstriations rugulo-subrugulose; pair of spiracles nearly to the middle ( Fig. 105 ). Upper tooth of mandible pointed, lower (or fourth) tooth rounded (Fig. 98). Clypeus in lateral view more projecting (Fig. 99, see arrow). Mesoscutum evenly granulose (Fig. 100). Head in dorsal view 1.8 times as broad as long (Fig. 101). Antenna with 29–35 antennomeres. Coxae more or less brownish to brown. fm: 2.4–2.8 mm. – Sporadic in the Palaearctic Region C. (S.) coxator (THOMSON, 1895)

2 (1) First tergite 1.6 times as long as broad behind, densely rugulose with striate elements; pair of spiracles clearly before the middle ( Fig. 104 ). Upper tooth of mandible slightly less pointed (Fig. 93). Clypeus in lateral view less projecting (Fig. 92, see lower arrow). Mesoscutum anteriorly faintly subgranulose (Fig. 94). Head in dorsal view twice as broad as long (Fig. 91). Antenna with 37–42 antennomeres. Coxae yellow. fm: 2.8–3 mm. – Korea Chorebus (Stiphrocera) senes sp. n.

2.) The distinction of Ch. granulosus and Ch. senes :

1 (2) First tergite 1.8–2 times longer than broad behind, rugulose with scrobiculate elements ( Fig. 106 ). Pterostigma narrow, ten times as long as wide, veins somewhat thick (Fig. 102). Head in dorsal view 1.8 times as broad as long, temple slightly longer than eye (cf. Fig. 101). First (or upper) tooth pointed, second tooth of mandible slightly less pointed (Fig. 103). Metasoma beyond first tergite dark rusty. f: 2.3 mm. – Asiatic Russia: Primorski krai C. (S.) granulosus TOBIAS, 1998

2 (1) First tergite 1.5–1.6 times longer than broad behind, rugulose with striate elements ( Fig. 104 ). Pterostigma wide, seven times as long as wide, veins thin (Fig. 96). Head in dorsal view twice as broad as long, temple slightly shorter than eye (Fig. 91). First (or upper) tooth less large, second tooth of mandible slightly more pointed (Fig. 93). Metasoma beyond first tergite rusty (1 m) or reddish yellow (f) with more or less brownish suffusion. fm: 2.8–3 mm. – Korea C. (S.) senes sp. n.
