Figs 15–16 View FIGURE 15 View FIGURE 16
Type material. Holotype. ♀, China, Yunnan Prov., Xishuangbanna Meng’a , 1050–1080m, 10.VI.1958, Pu Fuji, No. IOZ(E)1964568 ( IZCAS).
Diagnosis. This new species is very similar to A. grandis Wang et Chen, 2009 , but can be separated from the latter by the following characters: scape and pedicel yellowish brown (black in A. grandis ); wing membrane pale yellow, distally gray brown, fore wing with a black spot from vein 1-SR to middle of first discal cell (smoky gray, fore wing with light stripe at pterostigma basally to vein 2-SR+M); sixth and seventh metasomal tergites yellow (tergites black); fore wing vein 1-SR+M distinctly curved basally (weakly curved).
Description. Holotype, ♀, length of body 11.8 mm, of fore wing 12.0 mm, of ovipositor sheath 11.9 mm.
Head. Antenna with 62 antennomeres; apical flagellomere slightly acute, 2.5 × longer than its maximum width ( Fig. 16k View FIGURE 16 ); penultimate flagellomere 1.3 × longer than its maximum width, and 0.5 × as long as apical flagellomere; median flagellomeres 1.1 × longer than wide; first flagellomere 1.2 and 1.4 × longer than second and third, respectively, the latter being 1.2 × longer than wide; length of maxillary palp 0.8 × height of head; malar suture with some short setae and superficially sculptured ( Fig. 16i View FIGURE 16 ); clypeus height: inter-tentorial distance: tentorio-ocular distance = 7: 10: 10; clypeus with sparse long setae; eye not emarginate ( Fig. 16g View FIGURE 16 ); face sparsely and weakly punctate, and with dense long setae laterally ( Fig. 16g View FIGURE 16 ); eye height: shortest distance between eyes: head width = 17: 25: 46; frons smooth, strongly concave behind antennal sockets, with a median groove ( Fig. 16h View FIGURE 16 ); vertex smooth, with sparse short setae; shortest distance between posterior ocelli: shortest diameter of elliptical posterior ocellus: shortest distance between posterior ocellus and eye = 5: 7: 21; length of malar space equal to basal width of mandible; in dorsal view eye 1.1 × as long as temple; temples subparallel-sided behind eyes ( Fig. 16h View FIGURE 16 ).
Mesosoma. Length of mesosoma 1.3 × its height ( Fig. 16c View FIGURE 16 ); notauli only impressed anteriorly ( Fig. 16d View FIGURE 16 ); me- soscutum smooth and sparsely short setose ( Fig. 16d View FIGURE 16 ); scutellar sulcus deep, moderately narrow and crenulate ( Fig. 16d View FIGURE 16 ); scutellum smooth, with dense short setae posteriorly; metanotum moderately convex medially ( Fig. 16d View FIGURE 16 ); propodeum largely smooth, without medio-longitudinal carina or groove, and sparsely setose medially, with dense long setae laterally ( Fig. 16d View FIGURE 16 ).
Wings. Fore wing ( Fig. 16a View FIGURE 16 ): SR1: 3-SR: r = 19: 17: 4; 1-SR+M weakly curved after arising from 1-M, 1.2 × longer than 1-M; 2-SR: 3-SR: r-m = 15: 34: 12; m-cu straight, 3.0 × longer than 2-SR+M; cu-a weakly postfurcal. Hind wing ( Fig. 16b View FIGURE 16 ): 1r-m more or less straight; SC+R1: 2-SC+R: 1r-m = 25: 4: 16.
Legs. Length of fore femur: tibia: tarsus = 31: 36: 71; length of hind femur: tibia: basitarsus = 38: 65: 25; length of femur, tibia and basitarsus of hind leg 3.5, 9.3 and 6.2 × their maximum width, respectively.
Metasoma. Length of first tergite 1.2 × its apical width, smooth medio-basally, median area convex, rugose ( Fig. 16e View FIGURE 16 ); first tergite with a relatively long medio-longitudinal carina but absent anteriorly, and with developed lateral carinae, lateral grooves wide and crenulate ( Fig. 16e View FIGURE 16 ); medio-basal area of second tergite smooth, with a few oblique long crenulae laterally, attached to medio-longitudinal carina, carina absent near posterior margin of second tergite; antero-lateral areas of second tergite smooth, oblique anterior grooves wide and crenulate; second tergite largely smooth except for crenulae surrounded medio-basal area and in antero-lateral grooves ( Fig. 16e View FIGURE 16 ); second suture deep, crenulate, more or less straight medially ( Fig. 16e View FIGURE 16 ); antero-lateral areas of third tergite strongly convex; third tergite largely smooth but antero-lateral grooves weakly crenulate laterally; antero-lateral areas of fourth tergite reduced ( Fig. 16e View FIGURE 16 ); fourth–seventh tergites smooth ( Fig. 16e View FIGURE 16 ); hypopygium acute apically, reaching far beyond level of apex of metasoma; ovipositor sheath as long as fore wing.
Colour. Head and mesosoma largely yellow ( Fig. 15 View FIGURE 15 ); antenna (but outer side of scapus yellowish brown), mandible apically, stemmaticum, middle lobe of mesoscutum and lateral lobes, mesopleuron medially and ventrally, metapleuron and propodeum black ( Figs 16c, 16d, 16g, 16h View FIGURE 16 ); legs largely yellow, but claws, hind coxa, hind first trochanteriomere and hind femur (but apically yellow) black ( Fig. 16f View FIGURE 16 ); first–fifth metasomal tergites black, sixth and seventh tergites yellow ( Fig. 16e View FIGURE 16 ); wing membrane largely yellow, apically smoky gray, fore wing with a dark brown stigmal spot up to vein 1-SR+M, and a dark brown spot around posterior half of vein 2-1A, including dark brown veins 1-SR, 1-SR+M basally and 3-CU1 (except anteriorly) and apically wings with wide dark brown area; pterostigma and remainder of veins yellow ( Figs 16a, 16b View FIGURE 16 ).
Biology. Unknown.
Distribution. China (Yunnan).
Etymology. Named after the blackish brown stigmal spot of the fore wing: “macula” is Latin for “spot” and “pennis” is Latin for “wing”.
