Chorebus (Stiphrocera) voltor sp. n. f

( Figs 119–125 )

Material examined (1 f) – Female holotype: Korea, prov. Ryang , Hyesan, hotel garden, 23 August 1971, leg. S. HORVATOVICH et J. PAPP (loc. no. 193) . – Holotype is in good condition: (1) glued on a pointed card at the pair of hind coxae, (2) left middle tibia + tarsus glued separately. Holotype is deposited in the Hungarian Natural History Museum ( Department of Zoology ), Budapest, Hym. Typ. No. 11394 .

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

Description of the female holotype. – Body 1.9 mm long. Antenna long, nearly twice longer than body and with 30 antennomeres. First flagellomere four times and penultimate flagellomere 3.6 times as long as broad, flagellum just attenuating. – Head in dorsal view cubic, 1.4 times as broad as long, eye a bit shorter than temple, temple slightly broadening ( Fig. 119 ), occiput excavated. Eye in first tergite lateral view 1.5 times as high as wide, temple a bit wider than eye, ventral half of temple narrowing ( Fig. 120 ). Inner margin of eyes ventrally slightly converging ( Fig. 121 ). Mandible 1.5 times as long medially as broad between upper and lower teeth, second tooth pointed, lower (or fourth) tooth somewhat retracted ( Fig. 122 ). Head polished.

Mesosoma in lateral view elongate, 1.5 times as long as high, polished. Notaulix distinct though shallow, narrow and smooth, reaching lineraform and deep prescutellar dimple (cf. Fig. 100). Propodeum rugose and with less visible hairs (i.e. without pubescence). Hairy rosette of mesopleuron weakly distinct. – Hind femur 3.8 times as long as broad distally ( Fig. 123 ). Hind tarsus somewhat longer than hind tibia.

Fore wing as long as body. Pterostigma eight times as long as wide, distally slightly narrowing, issuing r clearly proximally from its middle, 1–R1 somewhat shorter then pterostigma ( Fig. 124 , see arrows), r a bit longer than width of pterostigma, 3–SR + SR1 ending before tip of wing. First subdiscal cell closed distally, i.e. CU1b weakly sclerotized.

First tergite ( Fig. 125 ) long, 2.1 times as long as broad behind, beyond pair of spiracles parallel-sided, pair of spiracles near before middle of tergite, pair of basal keels meeting medially; tergite bare, apically with tuft of hairs; rugo-rugulose with striate elements. Other tergites polished. Second tergite trapezeform, slightly broader behind than long medially. Hypopygium pointed, ovipositor sheath in lateral view as long as second tarsomere of hind tarsus.

Scape, pedicel and first flagellomere yellow, rest of flagellum somewhat darkening yellowish brown to brown. Head, mesosoma and first tergite black, rest of metasoma yellow, hind tergites darkening brown. Mandible yellowish brown, palpi pale yellow. Legs yellow, fifth tarsomeres of legs faintly brownish. Wings hyaline, pterostigma and veins opaque light brownish.

Male and host unknown.

Distribution: Korea.

The new species, Chorebus (Stiphrocera) voltor , is nearest to Ch. cubocephalus TELENGA ( TELENGA 1934: 114, TOBIAS 1986: 187, 1998: 358) considering their cubicform head (Figs ll9, 128), however, the females of the two species are distinguished by a few features keyed:

1 (2) Fore wing: pterostigma twice longer than 1–R1 ( Fig. 126 , see arrows). First tergite relatively broad, 1.6 times as long as broad behind and slightly broadening posteriorly; second tergite transverse, almost twice broader than long ( Fig. 127 ). Temple in dorsal view not broadening, i.e. “parallel”-sided ( Fig. 128 ). Metasoma dark brown to black, with very faint to faint rusty suffusion of variable extent. f: 1.6–2.5 mm. – Palaearctic Region

C. (S.) cubocephalus ( TELENGA, 1934)

2 (1) Fore wing: pterostigma somewhat longer than 1–R1 ( Fig. 124 , see arrows). First tergite relatively narrow, 2.1 times as long as broad behind and parallel-sided; second tergite trapezeform, slightly broader behind than long ( Fig. 125 ). Temple in dorsal view slightly broadening ( Fig. 119 ). Metasoma yellow, apically darkening brownish, first tergite black. f: 1.9 mm. – Korea C. (S.) voltor sp. n.

The new species is similar to Chorebus (Stiphrocera) cubiculus sp. n. viewing their cubicform head, they are dintingushed by the following features:

1 (2) First tergite broad, 1.3 times as long as broad behind, evenly broadening posteriorly; second tergite transverse, antero-medially subgranulate ( Fig. 30 ). Head in dorsal view slightly less cubicform, 1.5 times as broad as long ( Fig. 24 ). Pterostigma parallel-sided ( Fig. 28 ). Antenna with 27 antennomeres. f: 2.2 mm. – Korea C. (S.) cubiculus sp. n.

2 (1) First tergite narrow, 2.1 times as long as broad behind, beyond spiracles parallel-sided; second tergite trapezeform and entirley polished ( Fig. 125 ). Head in dorsal view slightly more cubicform, 1.4 times as broad as long ( Fig. 119 ). Pterostigma narrowing distally ( Fig. 124 ). Antenna with 30 antennomeres. f: 1.9 mm. – Korea C. (S.) voltor sp. n.
