Dinotrema irekabi sp. n. fm

( Figs 53–60 )

Material examined (1 f + 2 m). – Female holotype: Korea, Mts Pektu , swept along lake-shore in grasses before Samzi-yan Hotel , 19 July 1977, leg. DELY et DRASKOVITS (loc. no. 376). One male paratype: Korea, Prov. Kengi, Mts Bagyon , Bagyon popo (= water fall), about 27 km NE from Kaesong , 7 June 1970, leg. S. MAHUNKA et H. STEINMANN (loc. no. 100). One male paratype: Korea, Mts Bagyon (= “Pakyon”), Bagyon popo, 27 km NE from Kaesong, 9 September 1971, leg. S. HORVATOVICH et J. PAPP (loc. no. 251) .

Holotype and two paratypes are deposited in the Hungarian Natural History Museum (Department ofZoology), Budapest, Hym. Typ. Nos 10538 (holotype) and 10539–10540 (paratypes) . – Holotype and paratypes are in good condition.

Etymology – The specific epithet “irekabi ” is the reverse form of bakeri indicating the close relation ofthe two species.

Description of the female holotype. – Body 1.9 mm long. Antenna one-fourth longer than body and with 22 antennomeres. First flagellomere three times and further flagellomeres 2.7 times as long as broad apically. – Head in dorsal view ( Fig. 53 ) transverse, 1.8 times as broad as long, eye 1.9 times as long as temple and strongly rounded. OOL three times as long as POL. Tentorial pit short, not reaching compound eye. Mandible along median line 1.4 times as long as broad between teeth 1 and 3 ( Fig. 54 ). Eye in lateral view 1.35 times as high as wide, temple beyond eye 0.52 times as wide as eye or eye 1.9 times as wide as temple. Head polished.

Mesosoma in lateral view 1.3 times as long as high. Mesoscutal dimple absent. Precoxal suture short, subcrenulate. Propodeum polished with a medio-longitudinal weak carina, close along carina subrugulose ( Fig. 55 ). Mesosoma polished. – Hind femur four times as long as broad distally ( Fig. 56 ). Hind basitarsus as long as tarsomeres 2–3 and halfoffourth tarsomere combined.

Fore wing about one-seventh longer than body. Second submarginal cell long, 3–SR three times as long as 2–SR, 4–SR almost straight and 2.3 times as long as 3–SR ( Fig. 57 ). Vein 1–2CU1 almost twice as long as m-cu.

First tergite ( Fig. 58 ) 2.1 times as long as broad behind, its hind halfmore broadening posteri - orly, pair ofbasal keels reaching hind end oftergite; hind halfoffirst tergite with striolae, further ter - gites polished. Ovipositor sheath twice as long as first tergite or as long as hind tarsus.

Ground colour ofbody dark brown to brown. Scape + pedicel yellowish, flagellum brownish grey. Clypeus brownish yellow, mandible yellow, palpi straw yellow. Tegula brown, parategula yellow. Pronotum yellowish, first tergite light brown. Legs yellow, hind tibia apically faintly brownish. Wings hyaline, pterostigma and veins greyish yellowish.

Description ofthe two male paratypes. – Similar to the female holotype. Body 2 mm long. An - tenna with 19 antennomeres, flagellomeres 2.5 times as long as broad. Eye 2.5 times as long as temple, latter more rounded ( Fig. 59 ). Propodeum close along carina not subrugulose ( Fig. 60 ).

Distribution: Korea.

The new species, Dinotrema irekabi , is the member ofthe smithi species-group and runs to D. bakeri (FISCHER) with the help ofF ISCHER’ s key (1969 a: 190–191). The two species seem to be very near to each other and their distinction is restricted to a few features not easy to recognize:

1 (2) Eye in dorsal view 1.6 times as long as temple. First tergite 1.7 times as long as broad behind (in FISCHER 1969 a: 199 Abb. V: 14 1.9 times). Antenna with

19 antennomeres, flagellomeres twice as long as broad. Fore wing: 3–SR

twice as long as 2–SR (Abb. V: 15 l. c.). Female : 1.9 mm. – U.S.A.

D. bakeri (FISCHER, 1969)

2 (1) Eye in dorsal view 1.9 times (f) and 2.5 times (m) as long as temple ( Fig. 53 :

f, Fig. 59 : m). First tergite 2.1 times as long as broad behind in female ( Fig.

58), 2.2 times in male. Antenna with 22 (f) and 19 (m) antennomeres,

flagellomeres 2.7 times (f) and 2.5 times (m) as long as broad. Ovipositor sheath twice as long as first tergite or as long as hind tarsus. Fore wing: 3–SR

2.4 times as long as 2–SR ( Fig. 57 ). Female + male: 1.9–2 mm. – Korea
