Anastatus orientalis Yang and Choi, in Yang et al. 2015a: 292–300, figs 1–24. Described: both sexes.

Diagnosis. Female. Macropterous (Figs 20A, B). Fore wing with hyaline cross band behind marginal vein complete and with entirely white setae (Fig. 20G); infuscate region basal of hyaline band with uniformly dark setae and at least about 3× wider than cross band (Fig. 20G); 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. 20G). Head with scrobal depression distinctly separated from anterior ocellus, by distance (Fig. 20C: osd) at least similar to that of longitudinal diameter of ocellus. Antenna (Fig. 20D) with fl2 longer than pedicel but not all funiculars longer than wide, with at least apical funicular quadrate to slightly transverse (Fig. 20D, insert). Mesosoma with mesonotum (Fig. 20E) and acropleuron (Fig. 20F) dark with greenish or more bluish-green (posterior concave part of mesoscutum) luster, but pronotum except sometimes dorsomedially, usually at least ventral surface of procoxa, prepectus and tegula contrastingly paler; mesotibial apical spur pale (Fig. 20H); mesotarsus with all tarsomeres pale in contrast with dark mesotarsal pegs (Fig. 20H). Mesoscutum (Fig. 20E) with convex anterior part of medial lobe entirely punctate-reticulate; with posterior concave part of mesoscutum almost entire setose with white setae; mesoscutal lateral lobe with bare, minutely mesh-like-coriaceous band anterior of posteromedian carina relative to more oblique, coriaceous-alutaceous sculpture on outer inclined surface (Fig. 20E). Profemur with ventral margin evenly curved, without distinct angulation or tooth apically (cf. Fig. 1H).

MALE. Antenna (Fig. 21G) with scape yellow or at most narrowly brown dorsoapically; pedicel dark dorsally but yellow ventrally; flagellum with basal flagellomeres paler relative to darker brown apical flagellomeres such that darker multiporous plate sensilla contrasting in colour with surrounding cuticle (Fig. 21G), and consisting of clava and seven funiculars, with all funiculars longer than wide and clava not quite as long as combined length of apical two funiculars (Fig. 21G). Head with frons comparatively distinctly roughened, reticulate-rugulose (Figs 21C, D). Mesopleurosternum usually with distinctly paler, brown to yellow, Y-shaped set of marks consisting of transepisternal and femoral lines (Fig. 21E: fml, tsl). Legs beyond trochanters entirely yellow (Fig. 21B) or at most metafemur variably extensively darkened ventrally but pale dorsally over most of length (Fig. 21E). Fore wing (Fig. 21F) with costal cell dorsally setose along entire leading margin (Fig. 21H); basal cell uniformly setose with dark setae (Fig. 21H); disc with comparatively slender, oblique speculum (Fig. 21H: spc) closed posteriorly by line of dark setae.

Species concept. Our concept of A. orientalis is based on the original description plus reared females and males (CNC) obtained in 2013 from Dr. Soel-Mae Lee (Insect Pest Laboratory, Gwonseongu, South Korea) that were cultured from specimens originally collected in China (Beijing, Haidian, IV.2011, Z. Hou, from Lycoma delicatula (White, 1845) ( Hemiptera: Fulgoridae) on Ailanthus altissimus (Miller) Swingle (Simaroubaceae) from the same rearings as part of the original type series. The specimens were imported into South Korea in October 2011 and represent voucher specimens from Choi et al. (2014).

Regional records. The only records are from the original description.

Distribution. PALAEARCTIC: China (Beijing, Hebei, Shaanxi, Shandong, Tianjin), South Korea (Yang et al. 2015a).

Host. HEMIPTERA . Fulgoridae: Lycorma delicatula (White, 1845) (Choi et al. 2014; Yang et al. 2015a).

Remarks. Females of A. orientalis are very similar to those of A. fulloi except for procoxal and mesotarsal colour patterns, but males are readily separated by their entirely pale (Fig. 21B; Yang et al. 2015a, figs 3, 4) or almost entirely pale (Fig. 21E) legs as well as basally pale flagellum (Fig. 21G; Yang et al. 2015a, fig. 11), which support two distinct species. Males of A. orientalis also have the frons comparatively coarsely sculptured (Figs 21C, D; Yang et al. 2015a, fig. 21), though this is a relative feature and to some extent is affected by body size. Unlike A. fulloi males (Fig. 11D), A. orientalis males usually also have the most distinctly differentiated transepisternal and femoral lines (Fig. 21E, fml, tsl) of all treated regional species, though again this feature is variable both in A. orientalis (Yang et al. 2015a, fig. 22) and other species to some extent. Males of A. dexingensis (Fig. 5D) and A. formosanus (Fig. 9F) have a similar flagellar colour pattern as A. orientalis males (Fig. 21G), but differ by having extensively dark legs (Figs 5F, 9C). Among other features, females of A. dexingensis and A. formosanus differ from those of A. orientalis in having a profemoral denticle (Fig. 9A: arrow).
