Chorebus (Phaenolexis) fumoala sp. n. f
( Figs 50–58 View Figs 50–63 )
Material examined (2 ff) – Female holotype and one female paratype: Korea, prov. South Pyongan , ( Mts ) De-sang san, 12 km NE from Pyongyan, 18 July 1975, leg. J. PAPP et A. VOJNITS (loc. no. 267). – Holotype is in fairly good condition: (1) glued on a pointed card by the mesosternum, (2) tarsomeres 2–5 of fore left leg missing, (3) left flagellum deficient, present 28 flagellomeres, (4) right fore wing apically creased and slightly torned. Paratype is in less good condition: (1) mounted like the holotype, (2) head glued separately on the card. Holotype and paratype are deposited in the Hungarian Natural History Museum (Department of Zoology), Budapest, Hym. Typ. Nos 11384 (holotype) and 11385 (paratype) .
Etymology – The species name “fumoala ” refers to the brownish fumous colour of the wings.
Description of the female holotype. – Body 3.5 mm long. Antenna somewhat longer than body and with 41 antennometes. First flagellomere three times and penultimate flagellomere 1.7 times as long as broad. – Head in dorsal view transverse ( Fig. 50 View Figs 50–63 ), 1.8 times as broad as long, eye 1.5 times longer than temple, temple moderately rounded, occiput excavated. Eye in lateral view 1.7 times as high as wide and just wider than temple ( Fig. 51 View Figs 50–63 ). Mandible broad, a bit longer than broad between upper and lower teeth, first and second teeth pointed, 4th tooth somewhat retracted ( Fig. 52 View Figs 50–63 ). Head polished.
Mesosoma in lateral view elongated, 1.5 times as long as high, polished. Notaulix distinct, evenly deep, smooth ( Fig. 53 View Figs 50–63 ). Mesoscutal dimple short lineraform. Tuft of hairs (or pubescence) restricted antero-laterally on mesoscutum ( Fig. 53 View Figs 50–63 ). Propodeum and metapleuron pubescent. – Hind femur thick, 3.3 times as long as broad distally ( Fig. 54 View Figs 50–63 ). Hind basitarsus 1.75 times longer than second tarsomere ( Fig. 55 View Figs 50–63 ).
Fore wing as long as body. Pterostigma cuneiform, six times as long as wide, r a bit longer than width of pterostigma; 1–R1 0.6 times as long as length of pterostigma, i.e. 3–SR + SR1 approaching tip of wing ( Fig. 56 View Figs 50–63 , see arrows). First subdiscal cell closed distally, i.e. CU1b present.
First tergite ( Fig. 57 View Figs 50–63 ) 1.25 times as long as broad behind, evenly broadening posteriorly, pair of spiracles before middle of tergite, pair of basal keels meeting and reaching middle of tergite; rugose and fairly hairy with apical tufts. Further tergites polished. Hypopygium pointed, ovipositor sheath thick and as long as hind tarsomeres 1–2 combined ( Fig. 58 View Figs 50–63 ).
Scape and pedicel brownish yellow, flagellum dark brown, ventrally faintly brownish. Palpi yellow, mandible rusty brown. Head, mesosoma and first tergite black, rest of metasoma dark rusty, tergites laterally with brownish yellow maculae. Hypopygium apically yellowish to yellow, ovipositor sheath dark rusty brown. Fore leg yellow, fifth tarsomere brown; middle leg brownish yellow, tarsus fumous; hind leg rusty brown, tibia + tarsus dark rusty brown. Wings evenly brownish fumous, pterostigma light brown, veins brown to light brown.
Description of the female paratype. – Similar to the female holotype. Body 3.5 mm long. Head in dorsal view 1.7 times as broad as long. Hind femur 3.1 times as long as broad distally. First tergite 1.4 times as long as broad behind. Legs yellow, hind tibia + tarsus brownish fumous.
Male and host unknown.
Distribution: Korea.
The new species, Chorebus (Phaenolexis) fumoala , is nearest to Ch. (Ph.) stenocera (THOMSON) ; see TOBIAS’ s keys l986: 197 and 1998: 386, the new species differs from THOMSON’ s species by the following features:
1 (2) Notaulix distinct, mesoscutum bare and polished, tuft of hairs restricted antero-laterally ( Fig. 53 View Figs 50–63 ). Antenna with 41 antennomeres. First tergite somewhat more broadening posteriorly, 1.25 times as long as broad behind ( Fig. 57 View Figs 50–63 ). Ovipositor sheath in lateral view thick ( Fig. 58 View Figs 50–63 ). Hind femur relatively thick, 3.3 times as long as broad distally ( Fig. 54 View Figs 50–63 ). Wings brownish fumous. f: 3.5 mm. – Korea C. (P.) fumoala sp. n.
62–63. C. (P.) nomia (NIXON) : 62 = tarsomeres 1–2 of hind leg, 63 = hind end of female metasoma
2 (1) Notaulix indistinct, mesoscutum entirely hairy (cf. Fig. 30 View Figs 24–35 in GRIFFITHS 1964: 912). Antenna with 29–32 antennomeres. First tergite somewhat less broadening posteriorly, 1.8 times as long as boad behind ( Fig. 59 View Figs 50–63 ). Ovipositor sheath in lateral view thin ( Fig. 60 View Figs 50–63 ). Hind femur relatively thin, 3.8 times as long as broad distally ( Fig. 61 View Figs 50–63 ). Wings subhyaline. f: 3–3.2 mm. – Sweden, Russia, Azerbaidjan, Kazakhstan
C. (P.) stenocera (THOMSON, 1895)
The new species is also near to Ch. (Ph.) nomia (NIXON) ( NIXON 1937: 43, 1944: 106; TOBIAS 1998: 387), the two species are distinguished as follows:
1 (2) Notaulix distinct, mesoscutum bare and polished, tuft of hairs restricted antero-laterally ( Fig. 53 View Figs 50–63 ). Hind leg: basitarsus short, 1.75 times as long as second tarsomere ( Fig. 55 View Figs 50–63 ). Ovipositor sheath in lateral view thick and long ( Fig. 58 View Figs 50–63 ). Wings brownish fumous. Hind tibia and tarsus dark rusty brown. f: 3.5 mm – Korea C. (P.) fumoala sp. n.
2 (1) Notaulix indistinct, mesoscutum nearly entirely hairy. Hind leg: basitarsus long, 2.2 times as long as second tarsomere ( Fig. 62 View Figs 50–63 ). Ovipositor sheath in lateral view less thick and less long ( Fig. 63 View Figs 50–63 ). Wings subhyaline. Hind tibia and tarsus yellow, hind tibia apically and tarsus entirely faintly fumous. f: 2.5–3 mm. – Palaearctic Region C. (P.) nomia ( NIXON, 1937) View in CoL
