Antrusa bispinula sp. n. ♀

( Figs 66–72 )

Material examined (1 ♀). – Female holotype: Korea, prov. North Pyongan , Mt. Myohyang , taken at night from the lamps of Myohyang Hotel, 12 September 1980, leg. L. FORRÓ et GY. TOPÁL (loc. no. 652). – Holotype is deposited in the Hungarian Natural History Museum (Department of Zoology), Budapest, Hym. Typ. No. 10972.

Holotype is in good condition; left antenna damaged: with 25 antennomeres; glued on a pointed card by its mesosternum.

Etymology. – The species name “bispinula” refers to the two spinules on metanotum and on fore margin of propodeum.

Description of the female holotype. – Body 4.1 mm long. Antenna about as long as body and with 34 antennomeres (right antenna). First flagellomere 3.3 times, second flagellomere 2.6 times, middle flagellomeres twice and penultimate flagellomere 1.7 times as long as broad; first flagellomere 1.5 times length of second flagellomere. – Head in dorsal view ( Fig. 66 ) transverse, just 1.9 times as broad as long, eye as long as temple, temple rounded; head between eyes and temples equal in breadth. Ocelli small, elliptic, OOL twice as long as POL. Eye in lateral view 1.7 times as high as wide, temple somewhat wider than eye. Mandible stronghly broadening distally, as long as broad between upper and lower teeth, middle tooth basally wide ( Fig. 67 ). Face 1.75 times as wide as high. Head polished, hairy, face and clypeus densely hairy.

Mesosoma in lateral view 1.4 times as long as high. Pronope small. Notaulix extending to fore half of mesoscutum, narrow, evenly deep, crenulate. Mesoscutal dimple long, fairly deep, crenulate, extending on hind half of mesoscutum. Mesoscutum hairy, hairpunctured, shiny. Precoxal suture wide, crenulate, almost reaching fore margin of mesopleuron. Metanotum and fore margin of propodeum medially with a spinule each ( Fig. 68 , see arrows). Propodeum rugose without distinct areola, medially with a less distinct transverse carina. – Hind femur 4.5 times as long as broad dis-

tally, smooth ( Fig. 69 ). Hind tarsus one-fifth shorter than hind tibia. Hind basitarsus as long as tarsomeres 2–4 combined.

Fore wing as long as body. Pterostigma wide cuneiform ( Fig. 70 ), four times as long as wide proximally, r just shorter than width of pterostigma; 1–R1 short, 0.6 times as long as pterostigma and ending before tip of wing, 3–SR + SR1 as in Fig. 70 .Vein m–cu clearly antefurcal ( Fig. 70 ). First subdiscal cell closed distally. – Hind wing: cu–a issuing posteriorly from middle of M+CU + 1M ( Fig. 71 ).

First tergite ( Fig. 72 ) clearly and evenly broadening posteriorly, somewhat longer than broad behind, pair of converging keels distinct anteriorly and merging into longitudinal striation of tergite, striation with much anastomoses, dorsope deep, pair of spiracles at middle of tergite, tergite hairy. Tergites 2–3 slightly longer than first tergite, border between them hardly distinct, third tergite a bit longer than second tergite, together with further tergites polished; tergites 2–5 laterally with some hairs. Ovipositor sheath as long as hind basitarsus.

Body black. Scape yellow, pedicel brown, flagellum brownish black. Mandible testaceous, oral part with palpi pale yellow. Tegula, parategula and legs yellow, hind tibia distally brownish, hind tarsus with blackish suffusion. Wings hyaline, pterostigma brown, veins light brown to yellowish.

Male and host unknown.

Distribution: Korea.

The new species, Antrusa bispinula , is nearest to A. interstitialis (THOMSON) considering their fairly distinctly broadening first tergite, long-linearform mesoscutal dimpe and rugose propodeum; the two species are differentiated by the features keyed:

1 (2) Female: Temple in dorsal view bulged, i.e. head between temples somewhat broader than between eyes; head in dorsal view less transverse, 1.7 times as broad as long ( Fig. 73 ). Metanotum and fore margin of propodeum without spinule ( Fig. 74 , see arrows). First tergite 1.4 times longer than broad behind, rugose, second tergite basally rugulose otherwise polished ( Fig. 75 ). Antenna with 27 antennomeres. Mandible somewhat longer than broad between upper and lower teeth as in Fig. 76 (see arrows). Hind femur roughened ( Fig. 77 ). Tegula black, hind tibia darkening brown. ♀: 3 mm. – Europe A. interstitialis (THOMSON, 1895)

2 (1) Female: Temple in dorsal view not bulged, i.e. head between temples and eyes equally broad; head in dorsal view transverse, 1.9 times as broad as long ( Fig. 66 ). Metanotum and fore margin of propodeum with a spinule ( Fig. 68 , see arrows). First tergite slightly longer than broad behind, its striation with much anastomoses; second tergite entirely polished ( Fig. 72 ). Antenna with 34 antennomeres. Mandible as long as broad between upper and lower teeth as in Fig. 67 (see arrows). Hind femur smooth, shiny ( Fig. 69 ). Tegula and hind tibia yellow. ♀: 4.1 mm. – Korea A. bispinula sp. n.
