Figs 13–14
Type material. Holotype. ♀, China, Yunnan Prov., Xishuangbanna Meng’a, 1050–1080m, 10.VIII.1958, Pu Fuji, No. IOZ(E)1964570 (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: mesoscutum black (yellow in A. grandis, but sometimes lateral lobes blackish brown posteriorly); median area of first metasomal tergite with few striae, and remainder of tergite smooth (strongly sculptured); in dorsal view length of eye 0.9 × temple (1.2 ×); black spot of stemmaticum narrow, not extended posteriorly (spot extended posteriorly).
Description. Holotype, ♀, length of body 10.4 mm, of fore wing 9.8 mm, of ovipositor sheath 10.3 mm.
Head. Antenna incomplete, remaining part with 31 antennomeres; median flagellomeres 1.1 × longer than wide; first flagellomere 1.2 and 1.3 × longer than second and third, respectively, the latter being 1.8 × longer than wide; length of maxillary palp 0.9 × height of head; malar suture with some short setae and superficially sculptured (Fig. 14g); clypeus height: inter-tentorial distance: tentorio-ocular distance = 6: 11: 13; clypeus with two special long setae submedially; eye hardly emarginate (Fig. 14g); face smooth medially, with sparse and weak punctures laterally, and with dense long setae (Fig. 14g); eye height: shortest distance between eyes: head width = 15: 19: 37; frons largely smooth except for a few weak punctures, strongly concave behind antennal sockets, with a median groove (Fig. 14h); vertex largely smooth except for some weak punctures laterally, with sparse short setae; shortest distance between posterior ocelli: shortest diameter of elliptical posterior ocellus: shortest distance between posterior ocellus and eye = 3: 4: 9; length of malar space equal to basal width of mandible; in dorsal view length of eye 0.9 × temple; temples subparallel-sided behind eyes (Fig. 14h).
Mesosoma. Length of mesosoma 1.7 × its height (Fig. 14c); notauli complete (Fig. 14d); mesoscutum smooth and sparsely short setose posteriorly (Fig. 14d); scutellar sulcus deep, moderately narrow and crenulate (Fig. 14d); scutellum smooth, with dense short setae posteriorly; metanotum moderately convex medially (Fig. 14d); propodeum largely smooth, without medio-longitudinal carina or groove, and sparsely setose medially, with dense long setae laterally (Fig. 14d).
Wings. Fore wing (Fig. 14a): SR1: 3-SR: r = 33: 22: 5; 1-SR+M weakly curved after arising from 1-M, 1.4 × longer than 1-M; 2-SR: 3-SR: r-m = 9: 22: 8; m-cu straight, 2.2 × longer than 2-SR+M; cu-a more or less interstitial. Hind wing (Fig. 14b): 1r-m slightly curved; SC+R1: 2-SC+R: 1r-m = 22: 5: 11.
Legs. Length of fore femur: tibia: tarsus = 22: 25: 45; length of hind femur: tibia: basitarsus = 30: 57: 18; length of femur, tibia and basitarsus of hind leg 3.1, 11.4 and 4.5 × their maximum width, respectively.
Metasoma. Length of first tergite 1.8 × its apical width, smooth medio-basally, median area convex, reticulate (Fig. 14j); first tergite with a relatively long medio-longitudinal carina but absent anteriorly, and with lateral carinae distinctly developed, lateral grooves wide and crenulate (Fig. 14j); triangular medio-basal area of second tergite smooth and very large, with some oblique crenulae laterally, attached to very short medio-longitudinal carina, carina absent near posterior margin of second tergite; antero-lateral areas of second tergite smooth and small, oblique anterior grooves wide and crenulate; second tergite coarsely sculptured, except for medio-basal and antero-lateral areas, and posteriorly (Fig. 14e); second suture deep, crenulate, nearly straight medially (Fig. 14e); antero-lateral areas of third tergite strongly convex; third tergite largely smooth except for antero-lateral grooves crenulate; antero-lateral areas of fourth tergite reduced (Fig. 14e); fourth–seventh tergites smooth (Fig. 14e); hypopygium acute apically, reaching far beyond level of apex of metasoma; ovipositor sheath 1.1 × as long as fore wing.
Colour. Largely black (Fig. 13); head largely yellow, antenna, mandible apically and stemmaticum black (Figs 14g, 14h); pronotum and propleuron yellow (Fig. 14c); fore leg largely yellow but claws black; wing membrane infumate or smoky gray, but fore wing with a pale oblique stripe at level of vein 2-SR+M, pterostigma and veins dark brown (Figs 14a, 14b).
Biology. Unknown.
Distribution. China (Yunnan).
Etymology. Named after the relatively long temple: “longiquus” is Latin for “long, extended”.
