Chorebus (Etriptes) ebedus sp. n. f

( Figs 36–43 )

Material examined (2 ff) – Female holotype : Korea, ( Mt. ) Pektu san, Explosion lake, swept from grass, 2000–2500 m, 18 July 1977, leg. O. DELY et Á. DRASKOVITS (loc. no. 369). One female paratype : Korea, prov. Ryang , Sam-ji-yon, park, taken at light at night, leg. A. VOJNITS et L. ZOMBORI (loc. no. 1005). – Holotype and paratype are in good condition: (1) glued on a pointed card by the mesosternum, (2) right pterostigma of the paratype somewhat thickening basally and distally (abnormal?). Holotype and paratype are deposited in the Hungarian Natural History Museum (Department of Zoology), Budapest, Hym. Typ. Nos 11382 (holotype) and 11383 (paratype) .

Etymology – The new species received the phantasy name “ebedus ”.

Description of the female holotype. – Body 2.4 mm long. Antenna longer than body and with 33 antennomeres. First flagellomere 3.6 times and penultimate flagellomere 1.8 times as long as broad. – Head in dorsal view transverse ( Fig. 36 ), almost 1.9 times as broad as long, eye nearly 1.3 times as long as temple, temple rounded, occiput excavated. Inner margin of eyes somewhat converging ventrally (cf. Fig. 25 ). Eye in lateral view 1.6 times as high as wide and 1.6 times wider than temple, temple beyond eye evenly broad. Mandible ( Fig. 37 ) 1.8 times as long medially as broad between upper and lower teeth, lower teeth 3–4 equally large, second tooth pointed, upper tooth small. Head polished.

Mesosoma in lateral view 1.4 times as long as high, polished. Notaulix faintly distinct on fore declivous part of mesoscutum. Precoxal sulcus narrow and weakly crenulate ( Fig. 38 ). Mesoscutum and scutellum hairy. Propodeum rugose, lacking pubescence. Metapleuron with less distinct rosetteform hairs. – Hind coxa rugulose as in Fig 39 . Hind femur almost evenly broadening distally, 4.5 times longer than broad ( Fig. 40 ). Hind tibia one-fourth longer than hind tarsus; hind basitarsus just shorter than hind tarsomeres 2–3 combined.

Fore wing clearly longer than body. Pterostigma ( Fig. 41 ) narrow, 1.4 times as long as wide, issuing r basally, r twice longer than width of pterostigma. 1–R1 0.66 times as long as pterostigma, 3–SR + SR1 approaching tip of wing ( Fig. 41 , see arrows). First subdiscal cell closed, though CU1b weakly sclerotized ( Fig. 42 , see arrow).

First tergite ( Fig. 43 ) evenly broadening posteriorly, 1.4 times as long as broad behind, pair of spiracles before middle of tergite, basal pair of keels meeting and continuing in a median keel posteriorly, keel rather weak; tergite evenly rugose with diffuse hairs. Second tergite basally with weak striation ( Fig. 43 ), otherwise together with further tergites polished. Ovipositor sheath in lateral view short, somewhat longer than basitarsus of hind leg.

Antenna and body black, metasoma beyond first tergite with weak rusty suffusion. Mandible brownish yellow, palpi pale yellow. Legs brownish yellow, tibiae 1–2 apically weakly, tarsi 1–2 slightly more darkening; hind tibia apically and entire tarsus dark fumous, hind coxa brown. Wings faintly fumous, pterostigma and veins light opaque brown.

Description of the female paratype. – Similar to the female holotype. Body 2.6 mm long. Inner margin of eyes parallel. Pair of spiracles near to middle of first tergite.

Male and host unknown.

Distribution: Korea.

The new species, Chorebus (Etriptes) ebedus , runs to Ch. (E.) talaris (HALIDAY) with the help of TOBIAS’ s key (1986: 173, 1998: 354) considering their common feature: hind coxa more or less rugose ( Fig. 39 ); the two species are distinguished by the features keyed:

1 (2) Second tergite almost entirely striate; first tergite 1.6 times as long as broad behind, rugulose-subrugulose with striate elements ( Fig. 44 ). Precoxal sulcus wide, crenulated ( Fig. 45 ). Fore wing: 1–R1 short, 0.5 times as long as pterostigma ( Fig. 46 ). Temple slightly less rounded and a bit longer than eye; head in dorsal view 1.7–1.8 times as broad as long ( Fig. 47 ). Legs yellow. f: 2.5–3 mm. – Europe, Asiatic Russia: Far East

C. (E.) talaris (HALIDAY, 1839)

2 (1) Second tergite only basally striate; first tergite 1.4 times as long as broad behind, rugose ( Fig. 43 ). Precoxal sulcus narrow, weakly crenulated ( Fig. 38 ). Fore wing: 1–R1 0.66 times as long as width of pterostigma ( Fig. 41 ). Temple slightly more rounded and as long as eye; head in dorsal view 1.9

times as broad as long ( Fig. 36 ). Legs brownish yellow with much dark pattern. f: 2.4–2.6 mm. – Korea C. (E.) ebedus sp. n.

Disregarding the weak sculpture of hind coxa the new species runs to Ch. (St.) knautiae GRIFFITHS ( GRIFFITHS 1967: 572; TOBIAS 1998: 381), the two species are differing as follows:

1 (2) Second tergite entirely smooth, polished. Temple in dorsal view more rounded, eye slightly bulging; head transverse, twice broader than long ( Fig. 48 ). First tergite 1.6 times as long as broad behind, rather longitudinally rugose ( Fig. 49 ). Propodeum hairy, metapleuron with somewhat more distinct rosetteform hairs. Antenna with 38–41 antenomeres. Tegula yellow. f: 2.1–2.8 mm. – Poland, England, Romania, Asiatic Russia: Far East

2 (1) Second tergite basally striate ( Fig. 43 ). Temple in dorsal view rounded, eye not bulging; head slightly less transverse, 1.9 times as broad as long ( Fig.

36). First tergite 1.4 times as long as broad behind, rugose ( Fig. 43 ). Propodeum bare, metapleuron with somewhat less distinct rosetteform hairs.

Antenna with 33 antennomeres. Tegula brown. f: 2.4–2.6 mm. – Korea
