Material examined (4 f). – Female holotypes: Korea, Prov. Ryang, Chann-pay plateau, Samzi-yan, 1700 m, 24 July 1975, J. PAPP et A. VOJNITS (loc. no. 282). – One female paratype: Korea, Prov. Ryang, Chann-pay plateau, 24 km NW from Samziyan, road to Mt. Pektu, 2000 m, 24 July 1975, leg. J. PAPP et A. VOJNITS (loc. no. 281) . – One female paratype: Korea, Mt. Pektu , before Samziyan Hotel, lake-shore, netting in grasses, 19 July 1977, leg. DELY et DRASKOVITS (loc. no. 376) . – One female paratype: Korea, Prov. Ryang, Samziyan , 4 June 1985, leg. A. VOJNITS et L. ZOMBORI (loc. no. 992) .

Holotype and three paratypes are deposited in the Hungarian Natural History Museum (Department ofZoology), Budapest, Hym. Typ. Nos 10546 (holotype) and 10547–10549 (paratypes) . – Holotype is in good condition. The three paratypes are also in good condition except one paratype (loc. no. 992) with 13 antennomeres ofits left antenna.

Etymology. – The specific epithet “senex ” is a phantasy name.

Description ofthe female holotype. – Body 2.2 mm long. Antenna as long as body and with 20 antennomeres. First flagellomere three times, middle flagellomeres 1.6 times and penultimate flagellomere 1.5 times as long as broad apically. – Head in dorsal view ( Fig. 72 View Figs 72–80 ) transverse, 1.9 times as broad as long, eye almost one-third (or 1.4 times) longer than temple, temple rounded. OOL twice as long as POL. Tentorial pit just longer than its distance from compound eye. Mandible long, as long medially as broad between teeth, tooth 2 pointed, teeth 1 and 3 rounded ( Fig. 73 View Figs 72–80 ). Eye in lateral view 1.5 times as high as wide, beyond eye temple just less wide than eye. Head polished.

Mesosoma in lateral view stout, just longer than high. Mesoscutal dimple round and moderately deep. Precoxal suture short, restricted to middle ofmesopleuron, finely crenulate. Propodeum with a transverse carina, beyond carina antero-posteriorly rugo-rugulose, areola basalis missing, pair ofspiracles small ( Fig. 74 View Figs 72–80 ). Mesosoma polished. – Hind femur 3.8 times as long as broad medially ( Fig. 75 View Figs 72–80 ). Hind basitarsus as long as tarsomeres 2–3 combined.

Fore wing about one-third longer than body. Second submarginal cell long, 3–SR 2.1 times as long as 2–SR, 4–SR straight and 2.5 times as long as 3–SR. Vein 1–2CU1 twice as long as m–cu.

78 = mandible. – 79–80 = D. sphaerimembre (FISCHER) : 79 = hind femur, 80 = mandible

First tergite ( Fig. 76 View Figs 72–80 ) 1.75 times as long as broad behind, pair ofsmall spiracles at middle of tergite, beyond spiracles tergite less broadening, pair ofbasal keels merging into striation on poste - rior halfoftergite. Further tergites polished. Beyond fourth tergite tergites somewhat shrivelled.

Ovipositor sheath in lateral view somewhat longer than first tergite or as long as hind tarsomeres 1–2 combined and somewhat upwards curving.

Head and mesosoma blackish to dark brown, propodeum and metasoma brown. Scape and pedicel yellowish brown, flagellum greyish brownish. Mandible brownish yellow, palpi pale yellow. Tegula brown, parategula brownish yellow. Legs yellow. Wings hyaline, veins brownish to light brownish.

Description of the three female paratypes. – Similar to the female holotype. Body 2–2.3 mm long. Antenna with 19–22 antennomeres (19: 1 f, 20: 1 f, 22: 1 f), penultimate flagellomere 1.4–1.5 times as long as broad. Propodeum beyond transverse carina rather rugose (1 f). Hind femur 3.8 times (1 f) to 4 times (2 f) as long as broad distally. First tergite 1.6–1.8 times as long as broad behind (1.6: 1 f, 1.7: 1 f, 1.8: 1 f). Body black (1 f) or blackish brown (1 f).

Male and host unknown.

Distribution: Korea.

The new species, Dinotrema senex , is closely related to D. cratocera (THOMSON) and with the help ofF ISCHER’ s key (1976) runs to this species; the distinction between the two species is presented as follows:

1 (2) Precoxal suture long, reaching fore margin of mesopleuron (Abb. 36 in

FISCHER 1976: 362). Antenna with 23–28 antennomeres, flagellomeres somewhat longer, penultimate flagellomere (1.6–)1.7–1.8 times as long as broad.

First tergite 2–2.1 times as long as broad behind, slightly less broadening posteriorly ( Fig. 77 View Figs 72–80 ). Mandible 1.5 times as long medially as broad between teeth

1 and 3, its upper tooth slightly more rounded ( Fig. 78 View Figs 72–80 ). Ovipositor sheath shorter to just as long as first tergite. Female: 2.2–2.4 mm. – Sweden, Austria

D. cratocera (THOMSON)

2 (1) Precoxal suture short, not reaching fore margin of mesopleuron. Antenna with 19–22 antennomeres, flagellomeres somewhat less long, penultimate flagellomere 1.4–1.5 times as long as broad. First tergite 1.6–1.8 times as long as broad behind, slightly more broadening posteriorly ( Fig. 76 View Figs 72–80 ). Mandible 1.7 times as long medially as broad between teeth 1 and 3, its upper tooth slightly less rounded ( Fig. 73 View Figs 72–80 ). Ovipositor sheath somewhat longer than first tergite. Female: 2–2.3 mm. – Korea D. senex sp. n.

With the help ofF ISCHER’ s key (l.c.) the new species runs also to D. sphaerimembre (FISCHER) , however, the two species are separated by the features keyed:

1 (2) Head in dorsal view between temples just broader than between eyes, eye as long as temple. Middle flagellomeres subcubic, i.e. just longer than broad (Abb. 31 in FISCHER 1973 b: 121). Hind femur 4.5–5 times as long as broad distally ( Fig. 79 View Figs 72–80 ). Mandible 1.4 times as long medially as broad between teeth 1 and 3, teeth 1 and 3 somewhat pointed ( Fig. 80 View Figs 72–80 ). Ground colour ofbody black. Female: 1.9–2 mm. – Austria, Denmark

D. sphaerimembre (FISCHER, 1973)

2 (1) Head in dorsal view between temples as broad as between eyes, eye one-third longer than temple ( Fig. 72 View Figs 72–80 ). Middle flagellomeres 1.6 times as long as broad. Hind femur 3.8–4 times as long as broad medially ( Fig. 75 View Figs 72–80 ) or distally. Mandible 1.7 times as long medially as broad between teeth 1 and 3, teeth 1 and 3 rounded ( Fig. 73 View Figs 72–80 ). Ground colour ofbody blackish brown to brown. Female: 2–2.3 mm. – Korea D. senex sp. n.
