Dinotrema crux sp. n. fm

( Figs 16–21 , 87 )

Material examined (1 f + 6 m) – Female holotype + one male paratype (in Budapest): Korea, Prov. South Phenan (= Pyongyan), Bongha ri, on the river Tedong , 45 km E from Pyongyang , 23 May 1970, leg. S. MAHUNKA et H. STEINMANN (loc. no. 19). – Three male paratypes (two males in Coll. KU, one male in Budapest): Korea, Kyongbuk , Ponghwa Myongho, Kokye, 28 May 1993, leg. D.-S. KU . – Two male paratypes (in Coll. KU): Korea, Kyongbuk , Ponghwa Myongho, Kwanchang-ri, 28 May 1993, leg. D.-S. KU .

Female holotype and two male paratypes are deposited in the Hungarian Natural History Museum (Department ofZoology), Budapest, Hym. Typ. Nos 10531 (holotype) and 10532–10533 (paratypes); four male paratypes are in Coll. KU (Sancheong, Republic ofKorea) .

Female holotype is in good condition, except left damaged antenna with 15 antennomeres; mounted on a pointed card by its lateral sternites ofmetasoma. Paratypes (six males) are in fairly good condition.

Etymology – The specific epithet “crux ” refers to the cruciform carination of the propodeum.

Description ofthe female holotype. – Body 2.3 mm long. Antenna short, as long as head, mesosoma and two-thirds ofmetasoma combined; with 18 antennomeres. Flagellum faintly attenuat - ing, first flagellomere 3.5 times, middle flagellomeres twice and penultimate flagellomere just more than twice as long as broad apically. – Head in dorsal view ( Fig. 16 ) transverse, 1.85 times as broad as long, eye 1.65 times as long as temple, temple rounded. OOL three times as long as POL. Tentorial pit large, about five times as long as its distance from compound eye. Mandible long, 1.7 times as long medially as broad between teeth 1 and 3; upper (or first) tooth relatively small, lower (or third) tooth widely rounded ( Fig. 17 ). Eye in lateral view 1.6 times as high as wide, beyond eye temple one-fourth less wide than eye. Head polished.

Mesosoma in lateral view 1.25 times as long as high. Mesoscutal dimple linear and fairly deep. Precoxal suture short; restricted to middle ofmesopleuron, finely crenulate. Propodeum polished and with a cruciform carination, i.e. medio-longitudinal and transverse keels fully present and forming a cross ( Fig. 18 ). Mesosoma polished. – Hind femur four times as long as broad distally ( Fig. 19 ). Hind basitarsus as long as tarsomeres 2–3 combined.

Fore wing as long as body. Second submarginal cell long, 3–SR clearly twice as long as 2–SR, 4–SR straight and somewhat more than twice as long as 3–SR. Vein 1–2CU(1) 2.1 times as long as m–cu ( Fig. 87 , see arrows).

First tergite ( Fig. 20 ) 1.35 times as long as broad behind, pair ofsmall spiracles at middle of tergite, tergite evenly broadening antero-posteriorly, pair ofbasal keels merging into uneven-sub - rugulose surface, laterally from keels tergite polished. Further tergites also polished. Ovipositor sheath as long as hind femur or somewhat longer than first tergite.

Scape, pedicel and flagellomeres 1–3 brownish yellow, rest of flagellomeres greyish brown. Head dark brown, palpi pale yellow, mandible yellow. Mesosoma reddish yellow, mesoscutum and scutellum brown. Tegulae yellow. Legs yellow, coxae and trochanters rather pale yellow. Tergites brownish, sternites brownish yellow. Wings hyaline, veins light brownish.

Description ofthe six male paratypes. – Similar to the female holotype. Body 1.8–2.1 mm long (1.8: 1 m, 1.9: 1 m, 2: 1 m, 2.1: 3 m). Antenna somewhat longer than body and with 19–21 antennomeres (19: 1 m, 20: 1 m, 21: 4 m), first falgellomere 2.6 times, middle and penultimate flagellomeres 2.3–2.5 times as long as broad apically. Head in dorsal view less transverse, 1.7–1.8 times as broad as long, eye 1.6–1.7 times as long as temple. Cruciform carination of propodeum somewhat stronger, along medio-longitudinal keel fairly widely uneven (1 m). Hind femur 3.8–4 times as long as broad medially. 3–SR 2–2.2 times as long as 2–SR. First tergite 1.7–1.8(–1.9) times as long as broad behind. Mesosoma brown above, brown to light brown below.

Host unknown.

Distribution: Korea.

The new species, Dinotrema crux , runs to D. macrocera (THOMSON) and D. cruciforme ( FISCHER, 1973 b) with the help ofF ISCHER’ s key to the signifrons species-group within the genus Dinotrema as well as to D. tricarinae sp. n. The three species are distinguished as follows:

1 (2) Eye in dorsal view just longer than temple, head in dorsal view 1.75 times as broad as long ( Fig. 22 ). Upper (or first) tooth of mandible relatively large ( Fig. 23 ). First tergite 2–2.2 times as long as broad behind. Propodeum with a faintly distinct and rugulose areola basalis, transverse carina present ( Fig. 24 ). Propodeum dark brown to blackish. Female: 1.5–2.5 mm, male: 1.8–2 mm. – Sweden, Austria, Mongolia D. macrocera (THOMSON, 1895)

2 (1) Eye in dorsal view 1.5–1.9 times as long as temple, head in dorsal view 1.85 times as broad as long ( Fig. 16 ). Upper (or first) tooth of mandible relatively small ( Fig. 17 ). First tergite 1.25 (f) and 1.7–1.8(–1.9) times (m) as long as broad behind ( Figs 20–21 ). Propodeum with cruciform carination, along carinae sometimes rugulose (m), propodeum usually polished ( Fig. 18 ). Propodeum yellowish to light brown. Female: 2.3 mm, male: 1.8–2.1 mm. – Korea D. crux sp. n.

*

1 (2) Head in dorsal view 1.7 times as broad as long, eye one-fourth longer than temple ( Fig. 25 ). Precoxal suture reaching fore margin of mesopleuron. Propodeum with cruciform carination, transverse carina laterally gradually less distinct, relatively widely rugulose medio-longitudinally ( Fig. 26 ). Antenna with 23–25 antennomeres (fm). Female: 2.5 mm, male: 2–2.2 mm. – Austria, Korea D. cruciforme (FISCHER, 1973)

2 (1) Head in dorsal view 1.85 times as broad as long, eye 1.5–1.7 times as long as temple ( Fig. 16 ). Precoxal suture short, not reaching fore margin of mesopleuron. Propodeum polished and with distinct cruciform carination, sometimes (m) along carinae closely subrugulose ( Fig. 18 ). Antenna with 18 (f)

and 19–21 (m) antennomeres. Female: 2.3 mm, male: 1.8–2.1 mm. – Korea

D. crux sp. n.

The new species resembling of D. tricarinae sp. n., the distinction ofthe two species is presented at this species, see there.
