Lower orbit about in line with ventral margin of torulus. Antenna (Fig. 39) with relative length (width) of scape = 35(5); pedicel 7(4); anellus 3.5(3.5); 1 st to 7 th funiculars: 8(4): 9(5): 10(6): 9(6): 8(6.5): 7.5(7): 7(7); clava 18(7.5). BODY. Pronotum in dorsal view acute-triangular, concave postero-medially, smooth to very fine coriaceous, with one seta on each side along anterior margin of collar and five setae posteriorly anterior to each spiracle; median groove shallow. Mesoscutum (Fig. 38) with anterior convex medial lobe rhomboidal with sides divergent anteriorly to about middle and convergent over about posterior half, 0.6 × total length of mesoscutum, coarsely punctate-reticulate and slightly convex, and posteriorly concave part smooth and shiny, and with long translucent setae directed laterally; lateral lobe with inclined inner surface shiny, smooth, with translucent setae along outer margin. Scutellar-axillar complex (Fig. 38) convex, longitudinally coarsely reticulate, scutellum 1.6 × longer than broad. Acropleuron (Fig. 36) with fine, longitudinally aligned coriaceous sculpture, anterior one-quarter with several translucent hair-like setae. Brachypterous; fore wing (Fig. 34) about 0.4–0.5 mm in length, 4 × as long as wide, with apex rounded and extending only slightly over middle of Mt2; basal plate with three dark brown setae; basal cell almost bare, only three or four brown setae apically; costal cell ventrally with four setae at base, and dorsally bare; SMV extending two-thirds length of wing, MV, STV and PMV absent; disc with basal two-thirds hyaline, almost bare, only several hyaline thin setae scattered, and apical one-third with dense yellowish-brown setae, without hyaline cross-band. LEGS (Fig. 36). Profemur with ventral margin evenly arched, without tooth. Middle leg with spur slightly shorter than basitarsus; mesotibia with apical pegs in a patch; basal four tarsomeres with black pegs on each side. Hind leg with basitarsus as long as following three tarsomeres combined. GASTER (Figs 34, 36). Slightly shorter than mesosoma; ovipositor exserted for distance equal to no more than half length of syntergum. Notes Of the original type material, only four unlabeled females were found that resemble the original description and illustration provided for A. meilingensis. One complete female is here interpreted as holotype of the species. A second female lacks the funicle and clava of both antennae, and left front leg and right metatarsi. The third female lacks the right protarsi, and the fourth female lacks its left antenna, right funicle and clava, and right mesotarsus. Remarks Females of this species resemble those of A. huangi, but are differentiated by the following characters: fore wing much shorter, extending only slightly over middle of Mt2 compared to middle of gaster for A. huangi (cf. Figs 32, 34); fore wing disc with apical one-third densely setose with yellowish-brown setae, without hyaline cross-band compared to fore wing disc of A. huangi with thinner brownish setae, and has a tapered hyaline cross-band behind marginal vein; anterior convex medial lobe rhomboidal compared to triangular for A. huangi with (cf. Figs 31, 38); hind leg with basitarsus as long as following three tarsomeres compared to following four tarsomeres in A. huangi (cf. Figs 33, 36). In the key of Kalina (1981), A. meilingensis keys out to A. gastropachae, which is a brachypterous form of A. bifasciatus (Geoffroy, 1785) based on the rearings and synonym of Ishii (1938). The original description of A. gastropachae (Ashmead 1904) states that the fore wings are “fuscous, with a transverse band at base and [within] apical third hyaline”, whereas A. meilingensis has the basal two-thirds hyaline and the apical one-third with yellowish-brown setae, which is similar to the fore wing color pattern of A. meilingensis females. Females of A. gastropachae determined in 2015 by L. Fusu in the Canadian National Collection of Insects, Arachnids & Nematodes (Ottawa) were examined by the senior author. Females have the medial lobe of mesoscutum triangular, the gaster longer than the mesosoma, and the scrobal depression distinctly delimited dorsally compared to A. gastropachae.
