VOJNITS (loc. no. 304). – Holotype is deposited in the Hungarian Natural History Museum (Department ofZoology), Buda - pest, Hym. Typ. No. 10530. The holotype is in good condition except left antenna with 14 antennomeres (i.e. distal part offlagellum missing). Etymology – The specific epithet alboacutum refers to the white colour of the ultimate flagellomere. Description ofthe male holotype . – Body 1.7 mm long. Antenna about one-sixth longer than body and with 18 antennomeres. First flagellomere almost four times and penultimate flagellomere twice as long as broad. – Head in dorsal view ( Fig. 10 ) transverse, twice as broad as long, eye twice as long as temple and somewhat bulging, temple rounded. OOL twice as long as POL. Tentorial pit short, not touching compound eye, its length equal to distance between pit and eye. Mandible stout, along its median line 1.25 times as long as broad between teeth 1 and 3 ( Fig. 11 ). Eye in lateral view 1.4 times as high as wide, temple beyond eye one-third less wide than eye. Head polished. Mesosoma in lateral view 1.2 times as long as high. Mesoscutal dimple missing. Precoxal suture short, subcrenulate. Propodeum smooth and shiny with a medio-longitudinal weak carina, close along carina subrugulose; latero-median pair ofspiracles ofpropodeum on anterior end ofa small swelling oflateral suture ofpropodeum ( Fig. 13 ). Mesosoma polished. – Hind femur five times as long as broad distally. Hind basitarsus as long as tarsomeres 2–4 combined. Fore wing about one-fifth longer than body. Second submarginal cell long, 3–SR 2.3 times as long as 2–SR , 4–SR 2.2 times as long as 3–SR ( Fig. 12 ). Vein 1–2(CU(1) 1.5 times as long as m–cu . Veins somewhat thickened. First tergite 1.4 times as long as broad behind, evenly broadening posteriorly, pair ofbasal keels merging into longitudinal substriation on hind halfoftergite. Further tergites polished. Scape, pedicel and first flagellomere yellow, second flagellomere darkening yellow to brownish, rest of flagellum greyish brownish, ultimate flagellomere whitish. Head, mesoscutum and scutellum dark brown, mesopleuron brown, propodeum light brown, pronotum brownish yellow. Tergites 1–2 yellow, rest oftergites brown. Clypeus brownish yellow, mandible yellow, palpi white. Tegulae yellow, parategulae whitish yellow. Legs yellow, coxae 2–3 whitish yellow, hind tibia darkening brownish. Wings hyaline, pterostigma and veins greyish yellowish. Female and host unknown. Distribution: Korea . The new species, Dinotrema alboacutum , is nearest to the Nearctic species D. bakeri FISCHER within the smithi -group considering the polished propodeum of both species with a medio-longitudinal carina; the two species are distinct by the following features: 1 (2) Mandible long, 1.9 times as long as broad (Abb. V : 13 in FISCHER 1969 a : 199 ). In dorsal view eye 1.6 times as long as temple. Pair ofspiracles of propodeum on its lateral suture as usual (Abb. V : 14 l. c.). First tergite 1.7 times as long as broad (in Abb. V : 14 l. c. 1.9 times). Hind femur four times as long as broad. Tergites 1–2 chestnut brown. Female : 1.9 mm . – USA ( Massachusetts ) D. bakeri FISCHER , 1969 2 (1) Mandible short, 1.25 times as long as broad ( Fig. 11 ). In dorsal view eye twice as long as temple ( Fig. 10 ). Pair ofspiracles ofpropodeum on anterior end ofa small swelling along lateral suture ofpropodeum ( Fig. 13 ). First ter - gite 1.4 times as long as broad behind. Hind femur five times as long as broad. Tergites 1–2 yellow. Male: 1.7 mm . – Korea D. alboacutum sp. n. Taking into consideration the Palaearctic species ofthe smithi -group ( FISCHER 1976: 352–353 ) D. alboacutum is nearest to D. dentatum ( TOBIAS ) , the two species are distinguished by the features keyed: 1 (2) Propodeum with a wide pentagonal areola basalis ( Fig. 15 ). In dorsal view eye a bit longer than temple ( Fig. 14 ). Fore wing: second submarginal cell less long, 3–SR 1.7 times as long as 2–SR ( Fig. 24 in TOBIAS 1962: 103 ). Antenna with 21–22 antennomeres. Ground colour ofbody black. Female: 1.7 mm. – European part of Russia ( Leningrad Region ) D. dentatum ( TOBIAS , 1962 ) 2 (1) Propodeum with a medio-longitudinal carina otherwise polished ( Fig. 13 ). Eye in dorsal view twice as long as temple ( Fig. 10 ). Fore wing: second submarginal cell long, 3–SR 2.2 times as long as 2–SR ( Fig. 12 ). Antenna with 18 antennomeres. Ground colour ofbody dark brown to brown. Male: 1.7 mm . – Korea D. alboacutum sp. n.
