Vipiomorpha yunnanensis sp. nov. Figures 35, 36

Material examined.

Holotype: ♀, China, Yunnan Prov., Jingkan, 18.V.1983, Liao Yichang, No. 841267 (ZJUH).

Diagnosis.

This new species is very similar to Vipiomorpha ypsilon Tobias, 1962 [China; Korea; Russia], but can be separated from the latter by the following characters: in dorsal view length of eye 2.3 × temple (1.5 × in V. ypsilon); mesoscutum reddish yellow (black); hind wing vein 2-SC+R 1.2 × as long as vein 1r-m (0.7 ×); median spots of T II touching lateral spots anteriorly (not touching lateral spots); T V largely rugose (largely smooth); scape blackish brown (yellowish brown, with a black brown streak dorsally); pterostigma yellowish brown (blackish brown).

Description.

Holotype, ♀, length of body 6.6 mm, of fore wing 6.0 mm, of ovipositor sheath 8.0 mm.

Head. Antenna with 50 antennomeres; apical antennomere acute, 1.5 × longer than its maximum width (Fig. 36k); third antennomere 1.2 and 1.3 × longer than fourth and fifth, respectively, the latter 1.6 × longer than wide; median antennomeres ca. 1.1 × longer than their width; malar suture with dense short setae (Fig. 36i); clypeus height: inter-tentorial distance: tentorio-ocular distance = 4: 11: 7; clypeus smooth and shiny, with a single row of long setae; eye weakly emarginate(Fig. 36g); face largely smooth, with sparse and long setae (Fig. 36g); eye height: shortest distance between eyes: head width = 11: 14: 26; frons largely smooth except for a few weak punctures, strongly depressed behind antennal sockets, with a strong median groove (Fig. 36h); vertex smooth, but with some sparse short setae; minimum distance between posterior ocelli: minimum diameter of elliptical posterior ocellus: minimum distance between posterior ocellus and eye = 4: 3: 8; temples largely smooth except for a few weak punctures, and with some short setae, slightly narrowed immediately behind eyes (Fig. 36h).

Mesosoma. Length of mesosoma 1.5 × its height (Fig. 36c); anterior margin of pronotum with a single row of short setae; notauli deeply impressed, with a few weak crenulae (Fig. 36d); mesoscutum smooth, with short and dense setae posteriorly (Fig. 36d); middle lobe of mesoscutum strongly convex medially; scutellar sulcus moderately wide and deep, with crenulae (Fig. 36d); scutellum with a few weak punctures, and with dense short setae posteriorly; metanotum strongly convex medially (Fig. 36d); propodeum largely smooth, with a complete and crenulate medio-longitudinal groove, with sparse setae medially, and with dense long setae laterally (Fig. 36d).

Wings. Fore wing (Fig. 36a): r very short; r: SR1: 3-SR: = 19: 19: 3; 1-SR+M straight, and 1.8 × longer than 1-M; 2-SR: 3-SR: r-m = 8: 19: 9; first submarginal cell of forewing short; vein SR1 ends basally of mid-point between pterostigma and wing tip (at ca. 0.44); cu-a interstitial. Hind wing (Fig. 36b): r-m weakly curved; SC+R1: 2-SC+R: 1r-m = 9: 6: 5.

Legs. Length of fore femur: tibia: tarsus = 20: 23: 30; length of hind femur: tibia: basitarsus = 31: 34: 18; length of hind basitarsus 5.7 × its maximum width (Fig. 36f).

Metasoma. Length of T I 1.1 × its apical width, median area convex and strongly rugose (Fig. 36e); lateral grooves of T I strongly crenulate (Fig. 36e); median length of T II 0.7 × as long as its apical width; T II strongly rugose but antero-lateral areas smooth (Fig. 36e); T II without medio-basal area; antero-lateral areas of T II developed and smooth, anterior grooves wide, with a few weak crenulae (Fig. 36e); second suture deep and wide, with crenulae, slightly curved medially (Fig. 36e); median length of T III 0.37 × as long as its apical width; T III-IV with antero-lateral areas (of T IV weak), and crenulate transverse subposterior groove (Fig. 36e); T V with weak crenulate transverse subposterior groove; T III-VI rugose except posteriorly (T V and T VI weakly so); T VII largely smooth, and with some long setae posteriorly; hypopygium rather acute apically, far beyond level of apex of metasoma; ovipositor sheath 1.33 × as long as fore wing.

Colour. Largely yellow (Fig. 35); antenna, eye, mandible apically, claws, middle tibia and tarsus, hind femur, tibia and tarsus and ovipositor sheath black (Figs 35, 36g, f); T I black, T II-IV largely black (except posteriorly and T IV laterally), and with a yellow Y-shaped spot, T V black medio-anteriorly (Fig. 36e); wing membrane infuscate, pterostigma and veins yellowish brown (Fig. 36a, b).
