Chorebus (Stiphrocera) cubiculus sp. n. f
( Figs 24–31 View Figs 24–35 )
Material examined (1 f) – Female holotype: Korea, Tesson , 35 km SW Pyongyan, waterbasin, swept from grass, 4 July 1977, leg. O. DELY et Á. DRASKOVITS (loc. no. 343) . – Holotype is in good condition: (1) glued on a pointed card by its hind part of mesosternum and hind pair of coxae, (2) right fore wing distally and longitudinally somewhat creased. Holotype is deposited in the Hungarian Natural History Museum ( Department of Zology ), Budapest, Hym. Typ. No. 11381 .
Etymology – The species name “cubiculus ” refers to the cubicformed head.
Description of the female holotype. – Body 2.2 mm long. Antenna one-sixth longer than body and with 27 antennomeres. First flagellomere 3.2 times and penultimate flagellomere 2.7 times as long as broad. – Head in dorsal view cubicform ( Fig. 24 View Figs 24–35 ), 1.53 times as broad (between temples) as long, temple just longer than eye, temple a bit swollen, occiput excavated. Eye in lateral view almost twice as high as wide, temple 1.2 times wider than eye and beyond eye narrowing ventrally. Inner margin of eyes slightly converging ventrally, face quadrate: slightly wider above than high ( Fig. 25 View Figs 24–35 ). Mandible broad, 1.3 times as long medially as broad between upper and lower teeth, second and fourth teeth pointed ( Fig. 26 View Figs 24–35 ). Head polished.
Mesosoma in lateral view elongated, 1.6 times as long as high, polished. Notaulix feebly distinct on declivous part of mesoscutum; prescutellar dimple linearform; mesoscutum evenly hairy. Precoxal sulcus narrow, subcrenulated. Propodeum rugose, with hairs on its postero-lateral part. Hairy rosette of mesopleuron less distinct. – Hind femur 3.8 times as long as broad distally ( Fig. 27 View Figs 24–35 ). Hind tarsus somewhat longer than hind tibia.
Fore wing as long as body. Pterostigma ( Fig. 28 View Figs 24–35 ) ten times as long as wide, parallel-sided, r somewhat longer than width of pterostigma; 1–R1 0.6 times as long as pterostigma ( Fig. 28 View Figs 24–35 , see arrows), 3–SR + SR1 ending before tip of wing, marginal cell narrow. First subdiscal cell closed, i.e. CU1b present though feebly sclerotized ( Fig. 29 View Figs 24–35 , see arrow).
First tergite ( Fig. 30 View Figs 24–35 ) 1.3 times as long as broad behind, evenly broadening posteriorly, pair of basal keels not meeting and reaching middle of tergite; tergite with a few striates, interstriations rather transversely rugulose, bare. Second tergite medially subgranulate, otherwise together with further tergites polished. Hypopygium less pointed, ovipositor sheath short ( Fig. 31 View Figs 24–35 ).
Scape and pedicel brownish yellow, flagellum brown to dark brown. Head and mesosoma black. Mandible ochre, palpi yellowish. Tegula brownish yellow. First tergite black with rusty tint, metasoma beyond first tergite ochre yellow, hind tergites darkening brownish. Legs deep yellow, fifth tarsomere brown to dark brown. Wings hyaline, pterostigma and veins light brown.
Male and host unknown.
Distribution: Korea.
The new species, Chorebus (Stiphrocera) cubiculus , is nearest to Ch. (St.) diremtus (NEES) ( TOBIAS 1986: 187, 1998: 358) viewing their common features as the cubicform head and elongate mesosoma, however, the two species are different by the following features:
1 (2) First tergite more broadening posteriorly, 1.3 times as long as broad behind; second tergite medially subgranulate ( Fig. 30 View Figs 24–35 ). Temple in dorsal view a bit swollen ( Fig. 24 View Figs 24–35 ). Inner margin of eyes converging ventrally, face somewhat wider above than high ( Fig. 25 View Figs 24–35 ). Mandible broad, 1.3 times as long medially as broad between upper and lower teeth ( Fig. 26 View Figs 24–35 ). Hind leg entirely yellow. Metasoma beyond first tergite ochre yellow, hind tergites darkening brownish. f: 2.2 mm. – Korea C. (S.) cubiculus sp. n.
2 (1) First tergite less broadening posteriorly, 1.8–2 times as long as broad behind; second tergite polished ( Fig. 32 View Figs 24–35 ). Temple in dorsal view not swollen ( Fig. 33 View Figs 24–35 ). Inner margin of eyes either just converging ventrally or parallel, face distinctly wider than high ( Fig. 34 View Figs 24–35 ). Mandible less broad, 1.8–2 times tergites 1–2, 33 = head in dorsal view, 34 = head in frontal view, 35 = mandible as long medially as broad between upper and lower teeth ( Fig. 35 View Figs 24–35 ). Hind leg brown, tibia and tarsus brownish yellow. Metasoma beyond first tergite dark brown to blackish, tergites 2–3(–4) feebly with rusty suffusion. f: 1.8–2.2 mm. – Palaearctic Region C. (S.) diremtus (NEES, 1834) View in CoL The new species runs to Ch. (St.) cubocephalus (TELENGA) View in CoL ( TOBIAS 1998:
358) by their cubicformed head and elongate mesosoma, however, they are distinguished by a few features keyed:
1 (2) Temple in dorsal view swollen, i.e. head between temples a bit broader than between eyes ( Fig. 24 View Figs 24–35 ). First tergite 1.3 times as long as broad behind,
evenly broadening posteriorly; second tergite antero-medially subgranulate ( Fig. 30 View Figs 24–35 ). Pterostigma parallel-sided, 1–R1 0.6 times as long as pterostigma ( Fig. 28 View Figs 24–35 ). Ovipositor sheath short, clearly shorter than second tarsomere of hind leg ( Fig. 31 View Figs 24–35 ). Legs deep yellow. f: 2.2 mm. – Korea
C. (S.) cubiculus sp. n.
2 (1) Temple in dorsal view not swollen, i.e. temple “parallel-sided” ( Fig. 128 View Figs 119–128 ). First tergite 1.6–1.7 times as long as broad behind, less evely broadening posteriorly; second tergite polished ( Fig. 127 View Figs 119–128 ). Pterostigma cuneiform, 1–R1 0.5 times as long as pterostigma ( Fig. 126 View Figs 119–128 , see arrows). Ovipositor sheath long, as long as second tarsomere of hind leg. Legs brown to dark brown. f: 1.6–2.5(–2.8) mm. – Palaearctic Region (= Dacnusa cyclops NIXON, 1937 ) C. (S.) cubocephalus ( TELENGA, 1934)
