Gammabracon wangi sp. nov. Figures 15 View Figure 15 , 16 View Figure 16
Material examined.
Holotype: ♀, China, Fujian Prov., Kangshang , 9.IX.1993, Wang Jiashe, No. 854314 (ZJUH).
Diagnosis.
This new species is very similar to Gammabracon uniformis sp. nov., but can be separated from the latter by the following characters: basal third of pterostigma yellow, and apical 2/3 dark brown (uniformly yellow in G. uniformis ); hind leg yellow, tarsus infuscate (blackish brown); hind wing vein SC+R1 2.2 × longer than vein 1r-m (1.7 × vein 1r-m); hind femur 3.9 × as long as its maximum width (4.8 ×); fore wing vein cu-a slightly postfurcal (interstitial); medio-basal area of T II relatively large (small).
Description.
Holotype, ♀, length of body 10.5 mm, of fore wing 9.7 mm, of ovipositor sheath 17.1 mm.
Head. Antenna with 61 antennomeres; apical antennomere strongly acute, 1.9 × longer than its maximum width (Fig. 16k View Figure 16 ); penultimate antennomere 1.3 × longer than its maximum width, and 0.7 × as long as apical antennomere; median antennomeres 1.2 × longer than wide; third antennomere 1.3 and 1.4 × longer than fourth and fifth, respectively; third and fourth antennomeres 1.8 and 1.4 × longer than wide, respectively; length of maxillary palp 0.9 × height of head; malar suture with dense short setae (Fig. 16i View Figure 16 ); clypeus height: inter-tentorial distance: tentorio-ocular distance = 6: 11: 10; clypeus coarsely rugose, with sparse long setae; eye weakly emarginate (Fig. 16g View Figure 16 ); face coarsely sculptured, with some sparse and long setae (Fig. 16g View Figure 16 ); frons smooth, distinctly depressed behind antennal sockets, with a median groove (Fig. 16h View Figure 16 ); vertex smooth, with a few short setae; minimum distance between posterior ocelli: minimum diameter of elliptical posterior ocellus: minimum distance between posterior ocellus and eye = 5: 7: 18; temples largely smooth except for a few weak punctures, and with sparse long setae laterally, subparallel immediately behind eyes (Fig. 16h View Figure 16 ); in dorsal view length of eye 1.6 × temple.
Mesosoma. Length of mesosoma 1.8 × its height (Fig. 16c View Figure 16 ); notauli distinctly impressed (Fig. 16d View Figure 16 ); scutellar sulcus wide and deep, with crenulae (Fig. 16d View Figure 16 ); scutellum with a weak emargination medio-anteriorly, and with some short setae posteriorly; metanotum convex medially, but without median carina anteriorly; propodeum largely smooth except for a few crenulae posteriorly, with sparse setae medially, and with dense long setae laterally (Fig. 16d View Figure 16 ).
Wings. Fore wing (Fig. 16a View Figure 16 ): SR1: 3-SR: r = 47: 31: 8; 2-SR: 3-SR: r-m = 19: 31: 10; m-cu 1.4 × longer than 3-CU1; cu-a weakly postfurcal. Hind wing (Fig. 16b View Figure 16 ): SC+R1 2.2 × longer than 1r-m; anterior margin weakly concave beyond the subbasal cell.
Legs. Length of fore femur: tibia: tarsus = 34: 38: 52; length of hind femur: tibia: basitarsus = 45: 77: 28; length of femur, tibia and basitarsus of hind leg 3.9, 11.8 and 9.3 × their maximum width, respectively (Fig. 16f View Figure 16 ); hind tibial spurs 0.3 and 0.2 × as long as hind basitarsus.
Metasoma. Length of T I 1.1 × its apical width, median area convex and coarsely sculptured but posteriorly smooth, with a medio-longitudinal carina posteriorly (Fig. 16j View Figure 16 ); lateral grooves of T I smooth (Fig. 16j View Figure 16 ); T II largely smooth, but with some oblique carinae besides medio-longitudinal carina (Fig. 16e View Figure 16 ); T II medio-basal area connected to medio-longitudinal carina apically, but absent near posterior margin of T; antero-lateral areas of T II small, strongly acute apically, anterior grooves wide, with some strong crenulae (Fig. 16e View Figure 16 ); second suture deep and wide, with crenulae, more or less straight medially (Fig. 16e View Figure 16 ); T III largely smooth, median area strongly raised and posteriorly defined by a deep sinuate transverse crenulate groove, median area with a few weak punctures laterally; T IV with transverse depression medially; T III and T IV with antero-lateral areas and grooves (of T V weak); T IV-VII smooth; hypopygium rather acute apically, protruding just beyond level of apex of metasoma; ovipositor sheath 1.8 × longer than fore wing.
Colour. Largely yellow (Fig. 15 View Figure 15 ); antenna black (scapus yellow, with black stripe outer side) apical antennomeres (except for first-third antennomeres black) reddish yellow (Fig. 16i, k View Figure 16 ); eye, mandible apically, claws, part of dorsal carina and dorso-lateral carinae of T I, medio-longitudinal carina and lateral margins of medio-basal area of T II, ovipositor sheath black (Figs 15 View Figure 15 , 16e, g, j View Figure 16 ); hind tarsus infuscate (Fig. 16f View Figure 16 ); wing membrane yellow, pterostigma dark brown but basally yellow, veins largely brown, but fore wing vein 1-SR+M yellow (basally narrowly yellowish brown) (Fig. 16a, b View Figure 16 ).
