Dinotrema gradatim View in CoL sp. n. f

( Figs 37–42 View Figs 37–44 )

Material examined (1 f) – Female holotype: Korea, Prov. Ryang, Paekdu-san-milyong, 1500 m, 27 June 1988, leg. O. MERKL et GY. SZÉL (loc. no. 1353). – Holotype is deposited in the Hungarian Natural History Museum (Department ofZoology), Budapest, Hym. Typ. No. 10535.

The holotype is in good condition. – Taxonomic remark: The specimen was named by T. Munk (in 2000) as “close to caudata (Thoms.)” .

Etymology – The specific epithet “gradatim ” refers to the specific differences being only gradual.

Description ofthe female holotype. – Body 2 mm long. Antenna as long as body, with 22 (right antenna) and with 21 antennomeres (left antenna). First flagellomere 1.8 times (in lateral view), middle flagellomeres 1.5 times and penultimate flagellomere (left antenna) 1.7 times as long as broad. – Head in dorsal view ( Fig. 37 View Figs 37–44 ) transverse, 1.8 times as broad as long, eye 1.5 times as long as temple, temple rounded. OOL three times as long as POL. Tentorial pit short, not reaching compound eye. Mandible stout, 1.3 times as long medially as broad between teeth 1 and 3, less broadening distally, tooth 1 subpointed ( Fig. 38 View Figs 37–44 ). Eye in lateral view 1.5 times as long as wide, beyond eye temple slightly less wide than eye. Head polished.

Mesosoma in lateral view about as long as high. Mesoscutal dimple short linear. Precoxal suture short, subcrenulate. Propodeum polished, its medio-longitudinal strip anteriorly rugulose-uneven, posteriorly just uneven ( Fig. 39 View Figs 37–44 ). Mesosoma polished. – Hind femur four times as long as broad somewhat distally ( Fig. 40 View Figs 37–44 ). Hind basitarsus as long as tarsomeres 2–3 combined.

Fore wing about one-third longer than body. Second submarginal cell long, 3–SR 2.5 times as long as 2–SR, 4–SR faintly curved and 2.4 times as long as 3–SR. Vein 1–2CU1 twice as long as m–cu ( Fig. 41 View Figs 37–44 , see arrows).

First tergite ( Fig. 42 View Figs 37–44 ) 1.3 times as long as broad, evenly broadening posteriorly, pair ofspiracles beyond middle oftergite, pair ofweak keels reaching hind halfoftergite, hind halfoftergite tergite. – 43–44 = D. incarnatum (FISCHER): 43 = mandible, 44 = propodeum rather longitudinally subrugulose as in Fig. 42 View Figs 37–44 . Further tergites polished. Ovipositor sheath as long as hind tarsomeres 1–4 and halfof5th tarsomere combined and somewhat shorter than twice length of first tergite.

Ground colour ofbody blackish brown to dark brown. Antenna brown. Mandible and palpi light brown. Tegula brown, parategula yellowish. Legs brownish yellow. Propodeum and first tergite brown. Wings hyaline, pterostigma and veins brownish to light brownish.

Male and host unknown.

Distribution: Korea.

The new species, Dinotrema gradatim , is nearest to D. caudatum (THOMSON, 1895) and D. incarinatum (FISCHER, 1973) considering their rugulose-uneven medio-longitudinal strip ofpropodeum (i.e. propodeum not carinated, Figs 39 and 44 View Figs 37–44 ); the three species are distinct by the following features:

1 (2) First tergite 1.6 times as long as broad behind, posteriorly moderately broadening. Eye in dorsal view just longer than temple ( Fig. 2 View Figs 1–15 in STELFOX &

GRAHAM 1951:5). Vein 1–2CU1 three times as long as m–cu. Medio-longitudinal strip ofpropodeum evenly rugulose ( Fig. 10 View Figs 1–15 in l.c.). Fore wing: 3–SR

twice as long as 2–SR. Female and male: 1.8 mm. – Europe

D. caudatum (THOMSON, 1895)

2 (1) First tergite 1.3 times as long as broad behind, posteriorly strongly broadening ( Fig. 42 View Figs 37–44 ). Eye in dorsal view 1.5 times as long as temple ( Fig. 37 View Figs 37–44 ). Vein

1–2CU1 twice as long as m–cu ( Fig. 41 View Figs 37–44 , see arrows). Medio-logitudinal strip ofpropodeum anteriorly rugulose-uneven, posteriorly just uneven ( Fig. 39 View Figs 37–44 ).

Fore wing: 3–SR 2.5 times as long as 2–SR. Female: 2 mm. – Korea

D. gradatim sp. n.

1 (2) First tergite 1.75 times as long as broad behind. Mandible 1.75 times as long medially as broad between teeth 1 and 3, tooth 1 widely rounded ( Fig. 43 View Figs 37–44 ). Hind femur five times as long as broad. Middle flagellomeres 2.5 times as long as broad. Propodeum as in Fig. 44 View Figs 37–44 . Legs yellow. Female: 1.8–2 mm. – Austria, Hungary D. incarinatum (FISCHER, 1973) View in CoL

2 (1) First tergite 1.3 times as long as broad ( Fig. 42 View Figs 37–44 ). Mandible 1.3 times as long medially as broad between teeth 1 and 3, tooth 1 subpointed ( Fig. 38 View Figs 37–44 ). Hind femur four times as long as broad ( Fig. 40 View Figs 37–44 ). Middle flagellomeres 1.5 times as long as broad. Propodeum as in Fig. 39 View Figs 37–44 . Legs brownish yellow.
