Dinotrema tricarinae View in CoL sp. n. f

( Figs 81–86 View Figs 81–91 )

Material examined (1 f). – Female holotype: Korea, Chônnam , Yôchôn Nammyôn, Andori, 4 August 1993, leg. D.-S. KU. – Holotype is deposited in Coll. D.-S. KU (Sancheong, Republic ofKorea).

Female holotype is in good condition: right antenna damaged and with 21 antennomeres, right fore leg hardly visible owing to the overflowed gum (the specimen is glued on a pointed card).

Etymology. – The specific epithet “tricarinae ” refers to the three longitudinal carinae of propodeum.

Description ofthe female holotype. – Body 2.6 mm long. Antenna about as long as body and with 23 antennomeres. First flagellomere flattened (owing to dessication?), 2.3 times as long as broad apically, further flagellomere gradually shortening and indistinctly attenuating so that penultimate flagellomere just twice as long as broad. – Head in dorsal view ( Fig. 81 View Figs 81–91 ) transverse, 1.9 times as broad as long, eye just less than twice as long as temple, temple rounded. OOL three times as long as POL. Tentorial pit middle sized, about one-fourth longer than its distance from compound eye. Mandible short, 1.4 times as long medially as broad between teeth 1 and 3, clearly broadening distally, upper (or first) tooth large and directed upwards, middle (or second) tooth rather small and pointed, lower (or third) tooth rounded ( Fig. 82 View Figs 81–91 ). Eye in lateral view 1.4 times as high as wide, beyond eye temple 0.8 times as wide as eye. Head polished.

Mesosoma in lateral view 1.2 times as long as high. Mesoscutal dimple short linear and deep. Precoxal suture short, restricted to middle ofmesopleuron, crenulate. Propodeum carinated ( Fig. 83 View Figs 81–91 ): antero-transverse carina medially strong (in lateral view clearly pointed) and laterally weakening, propodeum areola basalis narrow, medio-longitudinal carina distinct (dividing areola basalis in two parts), laterally around spiracle with short carinae, pair ofspiracles small and at margin ofpropodeum, surface of propodeum polished. Mesosoma polished. – Hind femur thick, 3.4 times as long as broad distally ( Fig. 84 View Figs 81–91 ). Hind basitarsus as long as tarsomeres 2–3 combined.

Fore wing as long as body. Second submarginal cell less long, 3–SR twice as long as 2–SR, 4–SR faintly arched and 2.4 times as long as 3–SR. Vein 1–2CU1 1.7 times as long as m–cu ( Fig. 85 View Figs 81–91 , see arrows).

First tergite broad ( Fig. 86 View Figs 81–91 ), 1.8 times as long as broad behind, pair ofspiracles before middle oftergite, beyond spiracles tergite parallel-sided, pair ofkeels uniting medially and reaching almost hind end oftergite, hind halfoftergite striate. Further tergites polished. Ovipositor sheath as long as hind tarsomeres 1–2 combined.

Scape and pedicel brownish yellow, flagellum light brown. Head dark brown, mandible yellow, palpi pale yellow. Mesosoma dark brown with faint reddish suffusion, prosternum light testaceous, tegula brownish yellow. Legs pale yellow. Metasoma brownish testaceous, hind halfof metasoma with dark brown maculae. Wings hyaline, veins light brownish.

Male and host unknown.

Distribution: Korea.

The new species, Dinotrema tricarinae , is nearest to D. crux sp. n., however, the two species are clearly distinguished by the features keyed:

1 (2) Propodeum polished and with distinct cruciform carination ( Fig. 18 View Figs 16–26 ). Upper (or first) tooth of mandible small, mandible not broadening distally ( Fig. 17 View Figs 16–26 ). Vein 1–2CU1 2.1 times as long as m–cu ( Fig. 87 View Figs 81–91 , see arrows). First tergite 1.35 times (f) and 1.7–1.9 times (m) as long as broad behind ( Fig. 20–21 View Figs 16–26 ). Hind femur of female four times as long as broad distally ( Fig. 19 View Figs 16–26 ). Female: 2.3 mm, male: 1.8–2.1 mm. – Korea D. crux sp. n.

2 (1) Areola basalis ofpropodeum narrow, propodeum with three longitudinal carinae, along carinae uneven-subrugulose ( Fig. 83 View Figs 81–91 ). Upper (or first) tooth of mandible large, mandible distinctly broadening distally ( Fig. 82 View Figs 81–91 ). Vein

1–2CU1 1.7 times as long as m–cu ( Fig. 85 View Figs 81–91 , see arrows). First tergite 1.8

times (f) and 2.3 times (m) as long as broad behind. Hind femur of female 3.3

times as long as broad distally ( Fig. 84 View Figs 81–91 ). Female: 2.6 mm. – Korea

D. tricarinae sp. n.

The new species is related to D.spiniphorae (FISCHER) considering their several similar features, however, a few features differentiate them specifically as follows:

1 (2) Eye in dorsal view 1.3 times as long as temple, temple rounded ( Fig. 88 View Figs 81–91 ). Mandible less broadening distally, its upper tooth ofusual size and not di - rected upwards ( Fig. 89 View Figs 81–91 ). Hind femur of female 3.8–4 times as long as broad distally ( Fig. 90 View Figs 81–91 ). Propodeum as in Fig. 91 View Figs 81–91 . Female and male: 2.6–2.8 mm. – Germany D. spiniphorae ( FISCHER, 1985)

2(1) Eye in dorsal view just less than twice as long as temple, temple slightly more rounded ( Fig. 81 View Figs 81–91 ). Mandible clearly broadening distally, its upper tooth large and directed upwards ( Fig. 82 View Figs 81–91 ). Hind femur of female 3.4 times as long as broad distally ( Fig. 84 View Figs 81–91 ). Propodeum as in Fig. 83 View Figs 81–91 . Female: 2.6 mm. – Korea
