Diagnosis. Female. Brachypterous with fore wing extending only to about level of posterior margin of basal segment of gaster when body uncontorted ( Fig. 18A View FIGURE 18 ), and apically angulate to truncate or slightly emarginate ( Fig. 18F View FIGURE 18 ); discal region uniformly, densely setose with slightly lanceolate dark setae except for mesal region of orangish setae that at least extends to leading margin behind marginal venation but sometimes not to posterior margin so as to be enclosed by dark setae basally and apically and sometimes posteriorly ( Fig. 18F View FIGURE 18 ); marginal venation orangish along region of orangish setae, without differentiated stigmal or postmarginal veins; basal region often bare except for dark setae partly along mediocubital fold and white setae posteriorly and apically within basal cell ( Fig. 18F View FIGURE 18 ). Head ( Fig. 18C View FIGURE 18 ) with scrobal depression separated from anterior ocellus by distance subequal in length to longitudinal diameter of ocellus. Antenna ( Fig. 18H View FIGURE 18 ) with fl2 longer than pedicel but not all funiculars longer than wide, with at least apical funicular quadrate to slightly transverse ( Fig. 18H View FIGURE 18 , insert). Mesosoma with at least anterior convex part of medial lobe and often entire mesoscutum medially plus scutellar-axillar complex dark with greenish luster ( Fig. 18D View FIGURE 18 ), but at least outer inclined surface of mesoscutal lateral lobe and sometimes inner inclined surface or even entire posterior concave part of mesoscutum pale along with pronotum, procoxa, prepectus, tegula, and acropleuron over at least about posterior two-thirds ( Fig. 18E View FIGURE 18 ); mesotibial apical spur pale to variably strongly infuscate ( Fig. 18G View FIGURE 18 ); mesotarsus with all tarsomeres pale in contrast to dark mesotarsal pegs ( Fig. 18G View FIGURE 18 ). Mesoscutum ( Fig. 18D View FIGURE 18 ) with anteromedial lobe uniformly punctate-reticulate; posterior concave part entirely setose with white setae; mesoscutal lateral lobe carinately margined to abruptly angulate for most of length but with bare, finely sculptured dorsolongitudinal band anteriorly ( Fig. 18D View FIGURE 18 ). Profemur with ventral margin evenly curved, without distinct angulation or tooth apically (cf. Fig. 1H View FIGURE 1 ).

MALE. Antenna ( Fig. 19F View FIGURE 19 ) with scape extensively yellow but dark dorsoapically; pedicel dark; flagellum uniformly dark such that multiporous plate sensilla not contrasting in colour with surrounding cuticle ( Fig. 19F View FIGURE 19 , insert), and consisting of clava and seven funiculars, with at least fl6 and fl7 obviously longer than wide, and clava distinctly shorter than combined length of fl6–fl8 ( Fig. 19G View FIGURE 19 ). Head ( Fig. 19 C View FIGURE 19 ) with frons mesh-like coriaceous to pustulate. Mesopleurosternum uniformly dark ( Fig. 19B View FIGURE 19 ). Front leg with trochanter, trochantellus, tibia and tarsus pale, but femur extensively dark at least over posterior surface and sometimes mostly dark except apically; middle leg similar in colour to front leg but femur entirely or mostly much paler then metafemur, often darker brownishyellow than paler tibia, but dark brown only along length posteriorly or over dorsal and ventral surfaces posteriorly; hind leg with trochanter, trochantellus and tarsus pale, but femur mostly dark except apically, and metatibia with about basal half pale and apical half dark, though paler than respective femur ( Fig. 19B View FIGURE 19 ). Fore wing ( Fig. 19D View FIGURE 19 ) with costal cell dorsally setose along entire leading margin ( Fig. 19E View FIGURE 19 ); basal cell uniformly setose with dark setae ( Fig. 19E View FIGURE 19 ); disc with comparatively slender, oblique speculum ( Fig. 19E View FIGURE 19 : spc) sometimes partly obscured by underlying setae on ventral surface anteriorly and/or apically, and closed posteriorly by line of dark setae.

Species concept. Our concept of A. meilingensis   is based on examination of the female holotype and three female paratypes (FAFU) from Jiangxi Province as detailed by Peng et al. (2017)

Regional records. Non-type material examined. Fujian: Yashu Mountains, Ninghua County, 5–13.VII.2017, L. Peng (1♀ FAFU). Gansu: Kang County, Longnan City, 23.I.2018, Y. Chen, ex. Caligula japonica   egg, laboratory reared on Antherea pernyi (Guérin-Méneville)   eggs (64♀, 42♂ CNC). Hainan: Wenchang, ex. Stauropus alternus (Walker, 1855)   , Z. Wu (4♀ IZCAS). Hunan: Anren, Chenzhou City, VIII.1973, ex. Dendrolimus, Z. Li   (1♀ CAF). Jiangxi: Liantang, 6.VII.1956, ex. Dendrolimus, Zhang   (1♀ IZCAS).

Distribution. ORIENTAL: China (* Fujian, * Hainan, Hunan, Jiangxi). PALAEARCTIC: China (Gangsu).

Hosts. LEPIDOPTERA   . Lasiocampidae   : * Dendrolimus kikuchii   and D. punctatus   . Notodontidae   : * Stauropus alternus (Walker, 1835)   . Saturniidae   : Antheraea pernyi   (factitious host) and Caligula japonica ( Chen et al. 2019)   .

Remarks. Anastatus meilingensis   is one of four species known from China with short-winged females ( Fig. 18F View FIGURE 18 ). Females are most similar to those of A. gastropachae   , in part because of a similar mesoscutal colour pattern in which at least the outer inclined surfaces of the mesoscutal lateral lobes are pale along with most of the lateral surface of the mesosoma (cf. Figs 14E View FIGURE 14 , 18D View FIGURE 18 ). The reduced fore wings of females of the two species also share strongly reduced stigmal and postmarginal veins and have similar fore wing colour patterns, though A. gastropachae   females always have a complete hyaline cross band ( Fig. 14H View FIGURE 14 ) even if sometimes covered with dark rather than white setae ( Fig. 14I View FIGURE 14 ), whereas A. meilingensis   females either lack or at most have only a very slender and inconspicuous remnant of a hyaline cross band ( Fig. 18F View FIGURE 18 : cbr). The fore wings of A. meilingensis   females are also somewhat angulate to slightly emarginate apically ( Fig. 18F View FIGURE 18 ) whereas they are evenly curved for A. gastropachae   females ( Figs 14H, I View FIGURE 14 ). We differentiate males of A. meilingensis   from those of A. gansuensis   and A. shichengensis   by mesofemoral and metatibial colour pattern (see under further under latter two species).
