Chorebus (Chorebus) subcubicus sp. n. f

( Figs 107–112 View Figs 104–114 , 115–116 View Figs 115–118 )

Material examined (1 f) – Female holotype: Korea, (Mt.) Pektu san, swept in grass before Sam-zi-yan Hotel at the lake shore, 19 July 1977, leg. O. DELY et Á. DRASKOVITS (loc. no. 376) . – Holotype is in good condition: glued on a pointed card by its mesosternum. Holotype is deposited in the Hungarian Natural History Museum ( Department of Zoology ), Budapest, Hym. Typ. No. 11393 .

Etymology – The new species received the name “subcubicus ” referring to its cubicform head

( Fig. 107 View Figs 104–114 ).

Description of the female holotype. – Body 2 mm long. Antenna as long as body and with 22 antennomeres. First flagellomere 3.4 times and penultimate flagellomere 2.2 times as long as broad. – Head in dorsal view subcubic ( Fig. 107 View Figs 104–114 ), almost 1.6 times as broad between temples as long, temple swollen and 1.5 times longer than eye, occiput weakly excavated. Eye in lateral view almost 1.8 times as high as wide, temple a bit wider than eye. Inner margin of eyes (in frontal view) clearly converging ventrally ( Fig. 108 View Figs 104–114 ). Mandible just twice as long medially as broad between upper and lower teeth, second tooth large and pointed ( Fig. 109 View Figs 104–114 ). Head polished.

Mesosoma in lateral view 1.6 times as long as high. Pronotum, mesoscutum ( Fig. 110 View Figs 104–114 ) and mesopleuron granulate, dull to subshiny. Scutellum polished. Notaulix indistinct, prescutellar dimple present as a very fine linear sulcus ( Fig. 110 View Figs 104–114 ). Propodeum hairy, along fore margin and between pair of tubercules pubescent. – Hind femur 4.5 times as long as broad distally ( Fig. 111 View Figs 104–114 ). Hind tibia and tarsus less thin, i.e. realtively thick ( Fig. 111 View Figs 104–114 ).

Fore wing somewhat longer than body. Pterostigma ( Fig. 115 View Figs 115–118 ) cuneiform, ten times longer than wide, issuing r near to its middle, r slightly longer than width of pterostigma; 1–R1 0.65 times as long as pterostigma, i.e. 3–SR + SR1 evenly curved and approaching tip of wing ( Fig. 115 View Figs 115–118 ). First subdiscal cell closed distally as in Fig. 112 View Figs 104–114 (see arrow).

First tergite ( Fig. 116 View Figs 115–118 ) just longer than broad behind, clearly broadening posteriorly, pair of spiracles before middle of tergite, pair of keels meeting basally and continuing in a median keel beyond middle of tergite; tergite longitudinally striate without anastomoses. Other tergites polished. Hypopygium pointed, ovipositor sheath short, as long as second tarsomere of hind tarsus.

Antenna blackish, body black, second tergite with faint rusty tint. Mandible and palpi yellow. Hypopygium brownish. Legs yellow, all tarsi and tibiae 2–3 brownish fumous, hind coxa on its basal half brown. Wings hyaline, pterostigma and veins opaque brownish.

Male and host unknown.

Distribution: Korea.

The new species, Chorebus (Chorebus) subcubicus , runs to Ch. (Ch.) scabrifossa STELFOX with the help of TOBIAS’ s key (1986: 203, 1998: 408) and STELFOX’ s original description (1957: 115). The two species are similar to each other (sculptured mesosoma, more or less broadening temple, dark corporal colour), however, they are distinguished by the following features:

1 (2) Inner margin of eyes (in frontal view) converging ( Fig. 108 View Figs 104–114 ). Temple in dorsal view more swollen, head virtually less transverse ( Fig. 107 View Figs 104–114 ). Fore wing: 1–R1 short, 0.6 times as long as pterostigma, i.e. 3–SR + SR1 approaching tip of wing ( Fig. 115 View Figs 115–118 ). First tergite less broadening posteriorly, with less dense striation and no anastomoses; second tergite polished ( Fig. 116 View Figs 115–118 ). Antenna with 22 antennomeres. Hind femur less broadening distally, hind tibia and basitarsus less thin, hind basitarsus less than half as long as tibia ( Fig. 111 View Figs 104–114 ). f: 2 mm. – Korea C. (C.) subcubicus sp. n.

view, 114 = hind femur, tibia and basitarsus

2 (1) Inner margin of eyes (in frontal view) parallel as usually (cf. Fig. 34 View Figs 24–35 ). Temple in dorsal view less swollen, head virtually more transverse ( Fig. 113 View Figs 104–114 ). Fore wing: 1–R1 long, longer than pterostigma, i.e. 3–SR + SR1 reaching tip of wing ( Fig. 117 View Figs 115–118 , see arrows). First tergite somewhat more broadening posteriorly, with dense striation and a few anastomoses; second tergite longitudinally striolate ( Fig. 118 View Figs 115–118 ). Antenna 25–29 antennomeres. Hind femur somewhat more broadening distally, hind tibia and basitarsus thin, basitarsus nearly half as long as tibia ( Fig. 114 View Figs 104–114 ). f: 2.5–3.2 mm. – Ireland, Romania, Russia (European part, Far East: Primorski krai
