Diagnosis. FEMALE. Macropterous (Figs 23A, B). Fore wing with hyaline cross band behind marginal vein complete and with entirely white setae (Figs 23A, F); infuscate region basal of hyaline band with uniformly dark setae and about 2.0–2.5× wider than cross band (Fig. 23F); basal region with basal cell, mediocubital fold and cubital and vanal areas uniformly setose, though at least basal cell with comparatively inconspicuous white setae (Fig. 23F). Head with scrobal depression separated from anterior ocellus by distance greater than, but by less than 1.5×, longitudinal diameter of ocellus (Fig. 23C). Antenna (Fig. 23D) with fl2 longer than pedicel but not all funiculars longer than wide, with at least apical two funiculars subquadrate to slightly transverse (Fig. 23D, insert). Mesosoma, including procoxa (Fig. 23B), entirely dark, with concave posterior part of mesoscutum distinctly green or sometimes blue to purple in distinct contrast to rest of mesoscutum (Fig. 23A); mesotibial apical spur pale (Peng et al. 2017, fig. 48) to dark (Fig. 23G); mesotarsus with tarsomeres pale in contrast with dark mesotarsal pegs (Fig. 23G). Mesoscutum (Fig. 23A) with convex anterior part of medial lobe entirely punctate-reticulate to mesh-like reticulate, with somewhat larger reticulations posteriorly; posterior concave part of mesoscutum broadly setose with white setae medially, but apices of setae not extending laterally to carinate margin of lateral lobe; mesoscutal lateral lobe (Fig. 23E) entirely setose though with differentiated mesh-like-coriaceous band (Fig. 23E: arrow) anterior of posteromedian carina. Profemur with ventral margin obtusely angulate within about apical third (Figs 23H, I), but without distinct tooth-like denticle.

MALE. Antenna (Fig. 24E) with scape yellow; pedicel dark dorsally and pale ventrally; flagellum uniformly dark such that multiporous plate sensilla not contrasting in colour with surrounding cuticle (Figs 24E, F), and consisting of clava and seven funiculars, with all funiculars obviously longer than wide and clava subequal in length to combined length of apical two funiculars (Fig. 24E, F). Head (Fig. 24C) with frons mesh-like coriaceous to inconspicuously coriaceous-imbricate or reticulate. Mesopleurosternum uniformly dark (Fig. 24D). Front leg with trochanter, trochantellus, and femur mostly dark except narrowly apically, but tibia and tarsus pale; middle leg with similar in colour to front leg except femur apically often somewhat more extensively pale along anterior surface; hind leg with at least trochanter and tarsus pale, the trochantellus usually variably darkly infuscate, femur mostly to entirely dark, and tibia mostly dark, basally pale for distance at most equal to about apical width or about onequarter length of tibia, though sometimes more extensively on ventral surface (Fig. 24A). Fore wing (Fig. 24H) with costal cell dorsally setose along entire leading margin (Fig. 24I); basal cell uniformly setose with dark setae; disc with broad, quadrangular speculum (Figs 24H, I: spc) with underlying setae on ventral surface only anteriorly near parastigma, and closed posteriorly by dark setae.

Species concept. Our concept of A. shichengensis is based on the female holotype and four female paratypes from Jiangxi Province, as detailed by Peng et al. (2017). The single male allotype of A. shichengensis was not located by Peng et al. (2017), and our concept is based on sexes associated through rearing of individuals originally reared from the eggs of Tessaratoma papillosa collected in Changhua, Taiwan.

Remarks. Females of A. shichengensis are very similar to those of A. dexingensis and A. formosanus except that the profemur is angulate ventroapically (Figs 23H, I) rather than being produced into an acute spine-like process (Fig. 9A: arrow), which characterises females of the latter two species. Sculpture and setal pattern of the mesoscutal lateral lobe appear to be intermediate between those of A. dexingensis and A. formosanus females. The lateral lobe is entirely setose (Fig. 23E; Peng et al. 2017, fig. 45) as for A. dexingensis (Fig. 4D), but there is a differentiated, more finely sculptured mediolongitudinal band (Fig. 23E: arrow) anterior of the posteromedian carina similar to A. formosanus (Fig. 8D) females. The scrobal depression is also quite distinctly delineated dorsolaterally (Fig. 23C) and the hyaline cross band is uniformly wide with entirely white setae (Fig. 23F), more similar to A. formosanus females. Males that we treat as A. shichengensis are very similar to those of A. gansuensis and we cannot confidently distinguish the two at present, as is discussed under the latter species.
