( Figs 13–21 View Figs 13–26 )
Material examined(2 mm). – Male holotype: Mongolia, Bulgan aimak, 11 km W von Somon Bajannuur am See Bajan nuur, 1000 m, 14 Juni 1968, leg. Z. KASZAB (loc. no. 955). – One male paratype: Mongolia, Bulgan aimak, cca 20 km W von Somon Bajannuur, 1100 m, 18 June 1966, leg. Z. KASZAB (loc. no. 531) .
Holotype and paratype are deposited in the Hungarian Natural History Museum ( Department of Zoology ), Budapest, Hym. Typ Nos 10720 (holotype) and 10721 (paratype) .
Holotype and paratype are in good condition, glued on a pointed card by mesosternum.
Etymology. – The species name “badius ” is a phantasy name.
Description of the male holotype. – Body 3.4 mm long. Antenna about as long as body and with 34 antennomeres. First flagellomere 2.2 times and penultimate flagellomere 1.7 times as long as broad ( Fig. 13 View Figs 13–26 ). – Head in dorsal view ( Fig. 14 View Figs 13–26 ) transverse, 1.8 times as broad as long, eye somewhat longer than temple, temple rounded, occiput excavated; eye just protruding, i.e. head between eyes just broader than between temples. Ocelli less small, elliptic, OOL 2.5 times as long as POL. Head 1.4 times as broad as mesoscutum between tegulae. Eye in lateral view less high, 1.8 times as high as wide, temple beyond eye as wide as eye ( Fig. 15 View Figs 13–26 , see arrows). Mandible with strong teeth, 1.4 times longer than broad between upper and lower teeth ( Fig. 16 View Figs 13–26 ). Tentorial pit not reaching eye. Occiput and temple hairy. Head polished.
Mesosoma in lateral view elongate, 1.4 times as long as high, polished. Pronotum less hairy, pronope present. Precoxal suture narrow, fairly deep and subcrenulate ( Fig. 17 View Figs 13–26 ). Mesoscutum hairy anteriorly. Propodeum densely rugulose, hairy; metapleuron pubescent. – Hind femur 3.1 times as long as broad distally, clearly broadening distally ( Fig. 18 View Figs 13–26 ). Hind tibia and tarsus equal in length.
Fore wing about as long as body. Pterostigma ( Fig. 19 View Figs 13–26 ) cuneiform, 5.7 times as long as wide, issuing r near from its base, r 1.4 times as long width of pterostigma; 1–R1 0.65 times as long as pterostigma; 3–SR + SR1 bent, SR1 slightly S-form and approaching tip of wing. Subdiscal cell closed distally ( Fig. 20 View Figs 13–26 ).
First tergite ( Fig. 21 View Figs 13–26 ) slightly longer than broad behind, evenly broadening posteriorly, pair of spiracles at middle of tergite, rugose-rugulose, bald. Further tergites polished. Tergites 2–3 equal in length, border between them almost indistinct.
Ground colour of body black, hind tergites with faint brownish tint. Scape dark rusty, apically blackish; flagellum brownish black. Mandible dark rusty, palpi pale yellow. Tegula black, parategula brown. Coxae 1–2 brownish to brown, coxa 3 black. Legs 1–2 yellow; leg 3 reddish yellow, tibia distally dark fumous; tarsi brownish fumous. Wings hyaline, pterostigma and veins greyish brownish.
Description of the male paratype. – Similar to the male holotype. Body 3.3 mm long. Antenna with 36 antennomeres (right antenna damaged, with 32 antennomeres). Head in dorsal view 1.87 times as broad as long, eye just longer than temple. 1–R1 0.7 times as long as pterostigma. Hind leg with more darkening pattern.
Female and host unknown.
Distribution: Mongolia.
The new species, Chorebus (Stiphrocera) badius , is nearest to Ch. (S.) turcomanus (TOBIAS) considering their common features as the high number of the antennomeres (34–41), hairless and posteriorly broadening first tergite. The two species are separated by the features keyed:
1 (2) Precoxal suture wide and crenulate ( Fig. 22 View Figs 13–26 ). Temple in dorsal view clearly (i.e. 0.7 times) shorter than eye ( Fig. 23 View Figs 13–26 ). First tergite 1.4–1.5 times as long as broad behind, rugulose ( Fig. 24 View Figs 13–26 ). First flagellomere four times and penultimate flagellomere 2.4 times as long as broad ( Fig. 25 View Figs 13–26 ). Mandible with less pointed teeth ( Fig. 26 View Figs 13–26 ). Metasoma, except black first tergite, testaceous. f: 2.4–2.5 mm. – Hungary, Turkmenia Ch. (S.) turcomanus ( TOBIAS, 1966) View in CoL
2 (1) Precoxal suture narrow and finely crenulate ( Fig. 17 View Figs 13–26 ). Temple a bit shorter than eye ( Fig. 14 View Figs 13–26 ). First tergite somewhat longer than broad behind, rugose-
and 34th flagellomeres, 26 = mandible rugulose ( Fig. 21 View Figs 13–26 ). First flagellomere 2.2 times and penultimate flagellomere 1.7 times as long as broad ( Fig. 13 View Figs 13–26 ). Mandible with pointed teeth ( Fig. 16 View Figs 13–26 ). Metasoma black. m: 3.3–3.4 mm. – Mongolia Ch. (S.) badius View in CoL sp. n.
With the help of the key by TOBIAS (1998: 354–410) the new species runs to Ch. (S.) sakhalinensis TOBIAS , however, the two species are distinguished clearly from each other:
1 (2) Precoxal suture deep and rather wide. Pterostigma parallel-sided (cf. Fig. 138: 5 in TOBIAS 1998: 367). Flagellomeres distally 1.3 times as long as broad. Temple in dorsal view slightly swollen; head less transverse, 1.7 times as broad as long. Hind leg brownish yellow. m: 2.2 mm. – Asiatic Russia (Sakhalin) Ch. (S.) sakhalinensis TOBIAS, 1998
2 (1) Precoxal suture less deep and narrow ( Fig. 17 View Figs 13–26 ). Pterostigma cuneiform ( Fig. View Figs 13–26
19). Flagellomeres distally 1.8–1.7 times as long as broad. Temple in dorsal view not swollen; head transverse, 1.9 times as broad as long ( Fig. 14 View Figs 13–26 ). Hind leg yellowish with more or less dark suffusion. m: 3.3–3.4 mm. – Mongolia
