Chorebus (Stiphrocera) panilus sp. n.

(Figs 81–85, 87–91)

Type material – Female holotype: Korea, Kyongnam, Chinju-shi Kajwadong, 15 May 1993, leg. D.-S. Ku. Holotype is in good condition: (1) glued on a card point by its left meso- and metapleura, (2) all corporal parts well visible. Holotype is deposited in the Hungarian Natural History Museum, Budapest, Hym. Typ. No. 12125 .

Etymology – The new species received the latinized phantasy name ”panilus”.

Description of the female holotype – Body length 2.8 mm. Antenna long, almost twice longer than body and with 42 antennomeres. First flagellomere four times and penultimate flagellomere twice as long as broad, flagellomeres gradually shortening. – Head in dorsal view transverse (Fig. 81), twice as broad as long, eye somewhat (16:14) longer than temple, temple rounded. Ocelli on an equilateral triangle, OOL almost three times as long as POL. Eye in lateral view nearly 1.5 times as high as wide, and 1.2 times wider than gena (Fig. 82, see arrows). Mandible somewhat longer medially than broad between upper and lower teeth, first and second teeth large (Fig. 84). In frontal view inner margin of eyes converging ventrally, face almost twice as wide as high (Fig. 83, see arrows). Head polished, face later- ally hairpunctured, clypeus hairy.

Mesosoma in lateral view 1.3 times as long as high. Dorsope present, lateral part of pronotum bare. Notaulix absent. Mesoscutum evenly hairy except its hind third, mesoscutal midpit linearform. Scutellum polished, bare. Propodeum densely rugo-rugulose with longitudinal and transverse faint carinate elements, pubescent, rosette less distinct. Precoxal suture anteriorly on mesopleuron broken right-angled, narrow, crenulated, otherwise mesopleuron polished (Fig. 85). – Hind femur 4.1 times as long as broad, distally well broadening (Fig. 87). Hind tibia relatively thick, distally three times broader than basally (Fig. 87, see arrows). Hind tarsus somewhat shorter than hind tibia. Hind basitarsus as long as tarsomeres 2–4 combined.

Fore wing about one-sixth longer than body. Pterostigma narrow and parallel-sided (Fig. 88), twelve times as long as wide, r twice as long as width of pterostigma, 3–SR + SR1 as in Fig. 88, 1– R 1 long, slightly shorter than pterostigma (45:50) and reaching tip of wing. First subdiscal cell short, 1–2CU1 and cu–a fairly thick, closed distally albeit 2–1A weakly sclerotized (Fig. 89, see arrows).

First tergite (Fig. 90) 2.8 times as long as broad behind, parallel-sided, posteriorly almost 1.2 times broader than basally, pair of spiracles somewhat protruding and at middle of tergite; pair of basal keels rather weak, not meeting and merging into rugo-rugulosity of tergite; hind corner hairy. Further tergites polished. Tergites 2–3 as long as first tergite, second tergite longer than third tergite (28:22). Hypopygium pointed, ovipositor sheath as long as hind basitarsus, thin (Fig. 91).

Flagellum dark brownish to black, scape yellowish. Head, mesosoma and first tergite black, metasoma orange yellow. Palpi pale yellow. Tegula brown. Legs yellow, hind tibia apically and hind tarsus feebly dark fumous. Wings subhyaline, pterostigma blackish brown, veins yellow to light brown.

Male and host unknown.

Distribution: Korea.

Taxonomic position – Chorebus (Stiphrocera) panilus sp. n. is nearest to Ch. (S.) rubicundus Griffiths ( Griffiths 1968 b: 78) considering their common fea- tures: head in dorsal view transverse, metasoma beyond first tergite yellow or light brownish and precoxal suture (weakly) sculptured; the distinction between the females of the two species is as follows:

1 (2) Antenna with 42 antennomeres. Temple in dorsal view not swollen, i.e. rounded and not broader between temples than between eyes (Fig. 81). Fore wing: 1–R1 0.9 times as long as pterostigma and reaching tip of wing (Fig. 88). Hind tibia somewhat thick, distally three times broad- er than basally, hind femur thickening as in Fig. 87 (see arrows). First tergite parallel-sided, rugo-rugulose (Fig. 90). Tegula brown. f: 2.8 mm. – Korea Chorebus (Stiphrocera) panilus sp. n.

2 (1) Antenna with 28 antennomeres. Temple in dorsal view slightly swollen, i.e. between temples somewhat broader than between eyes (Fig. 92). Fore wing: 1–R1 0.5–0.6 times as long as pterostigma and ending far before tip of wing (Fig. 93, see arrows). Hind tibia rather thin, distally 1.3 times broader than basally, hind femur thickening as in Fig. 94 (see arrows). First tergite weakly broadening posteriorly, rugulose (Fig. 95). Tegula yellow. f: 2.1–2.2 mm. – Europe ( Germany, Poland, Hungary, Armenia)

The new species is also near and runs in Tobias’s key ( TobiAs 1998: 354– 410, couplets 33(32) – 34(33)) to Ch. (S.) rubicundulus Tobias ( TobiAs 1998: 360) , the distinctive features between the two species are as follows (according to the original description):

1 (2) Female: Antenna with 42 antennomeres. Notaulix restricted to ante-

rior declivous part of mesoscutum. Precoxal suture narrow, crenulated (Fig. 85). First tergite 2.8 times as long as broad posterior-

ly. Anterior half of mesoscutum hairy (posteriorly bare); occiput,

pronotum and anterior part of mesopleuron bare. f: 2.8 mm. – Korea

Chorebus (Stiphrocera) panilus sp. n.

2 (1) Male: Antenna with 27 antennomeres. Notaulix distinct, extending up to mesoscutal midpit, crenulated. Precoxal suture smooth. First tergite 3.5 times as long as broad posteriorly. Median part of mesoscutum (between notauli) hairy, lateral lobe bare; occiput fairly densely hairy, pronotum and anterior part of mesopleuron hairy. m: 2.2 mm. – Asiatic Russia (Primorski Krai) Chorebus (Stiphrocera) rubicundulus Tobias, 1998

Ch. (S.) albimarginis Griffiths ( Griffiths 1967: 860) is also near to the new species considering their loose tuft hairs on hind coxa (Fig. 35) and yellow legs; they can be differentiated as follows:

1 (2) In frontal view inner margin of eyes converging ventrally (Fig. 83). Mandible: first and second teeth strong (Fig. 84). Fore wing: 1–R1 long, 0.9 times as long as pterostigma (Fig. 88). Mesosoma in lateral view 1.3 times as long as high. Hind femur more broadening distally, 4.1 times as long as broad (Fig. 87, see arrows). Metasoma orange yellow, first tergite black. f: 2.8 mm. – Korea Chorebus (Stiphrocera) panilus sp. n.

2 (1) In frontal view inner margin of eyes parallel (Fig. 86). Mandible: first and second teeth less strong (Fig. 28). Fore wing: 1–R1 short, 0.6 times as long as pterostigma (cf. Fig. 22). Mesosoma in lateral view stout, just longer than high (50:45). Hind femur less boadening distally, 5–5.5

times as long as broad (Fig. 96). Metasoma dark to blackish brown, tergites 2–3 yellow(ish) to brownish. f: 1.9–2 mm. – Germany, Hungary
