Chorebus (Etriptes) bermus sp. n. f

( Figs 12–18 )

Material examined (1 f) – Female holotype: Korea, prov. Ryang , Chann-pay plateau, (Mt.) Pektu san, Mu-do-bong, 2100–2200 m, 25 July 1975, leg. J. PAPP et A. VOJNITS (loc. no. 288) . – Holotype is in good condition: glued on a pointed card by its left half mesosternum. Holotype is deposited in the Hungarian Natural History Museum ( Department of Zoology ), Budapest, Hym. Typ. No. 11380 .

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

Description of the female holotype.– Body 1.9 mm long. Antenna nearly 1.5 times as long as body and with 27 antennomeres. First flagellomere four times and penultimate flagellomere clearly twice as long as broad. – Head in dorsal view transverse ( Fig. 12 ), 1.8 times as broad as long, eye 1.35 times longer than temple, temple rounded, occiput excavated. Eye in lateral view just less than twice as high as wide, temple beyond eye as wide as eye and ventrally narrowing. Mandible 1.4 times as long as broad between upper and lower teeth, teeth 1 and 2 fairly large, tooth 3 small ( Fig. 13 ). Head polished.

Mesosoma in lateral view 1.4 times as long as high, polished. Notaulix indistinct. Mesoscutum antero-laterally hairpunctured. Prescutellar dimple short and linearform. Propodeum rugose, hairy, posteriorly densely hairy. Hairy rosette of metapleuron weakly distinct. Precoxal sulcus narrow, subcrenulate. – Hind coxa rugo-rugulose ( Fig. 14 ). Hind femur five times as long as broad ( Fig. 15 ). Hind tibia and tarsus equal in length.

Fore wing slightly longer than body. Pterostigma ( Fig. 16 ) eleven times as long as wide, parallel-sided, r 1.4 times longer than width of pterostigma; 1–R1 0.6 times as long as pterostigma, 3–SR + SR1 ending before tip of wing. First subdiscal cell open distally, i.e. short CU1b missing ( Fig. 17 , see arrow).

First tergite ( Fig. 18 ) 1.8 times as long as broad behind and parallel-sided; pair of spiracles before middle of tergite, pair of basal keels less distinct; tergite rugose, hairy, posteriorly with denser hairs. Other tergites polished. Hypopygium pointed, ovipositor sheath as long as second tarsomere of hind tarsus.

Antenna brown, scape + pedicel and first flagellomere basally yellowish. Head, mesosoma and first tergite black, rest of metasoma dark brown. Palpi brownish yellow. Legs brownish yellow, hind coxa brown. Wings hyaline, pterostigma and veins light brown.

Male and host unknown.

Distribution: Korea.

The new species, Chorebus (Etriptes) bermus , is nearest to Ch. (E.) subasper GRIFFITHS ( GRIFFITHS 1968 b: 72; TOBIAS 1998: 354) considering their common feature: the sculptured hind coxa; they are separated by the features keyed:

1 (2) Hind coxa densely rugose ( Fig. 19 ). Hind femur 4.2 times as long as broad distally and its outer side roughened ( Fig. 20 ). Head in dorsal view

1.65–1.7 times as broad as log, eye somewhat protruding ( Fig. 21 ). First tergite twice as long as broad behind and somewhat broadening posteriorly, roughly rugose ( Fig. 22 ). Mesoscutum densely punctate. Vein r twice as long as width of pterostigma ( Fig. 23 ). Hind femur reddish yellow. Body strong, f: 2.3–3 mm. – Poland, Hungary, Asiatic Russia: Kuril Islands

2 (1) Hind coxa rugo-rugulose ( Fig. 14 ). Hind femur five times as long as broad distally and its outer side smooth ( Fig. 15 ). Head in dorsal view 1.8 times as broad as long, eye not protruding ( Fig. 12 ). First tergite 1.8 times as long as broad behind and parallel-sided, rugose ( Fig. 18 ). Mesoscutum smooth, shiny, antero-laterally hair-punctured. Vein r 1.4 times as long as width of pterostigma ( Fig. 16 ). Hind femur yellow. Body gracile, f: 1.9 mm. – Korea C. (E.) bermus sp. n.
