Habitus (Figs. 1A, B). Body oval. Integumentary colour of body and appendages blackish; eyes black; elytra slightly iridescent, emerald green. Frons, genae and vertex and temples inserted with some moderately long, suberect, blackish setae, and with inconspicuous bluish white pubescence along mesal margins of lower eye lobes.

Elytra mostly glabrous; each elytron provided with about 11 small maculae of white pubescence, roughly arranged in four transverse rows and one vague macula along apical margin. Ventral surface clothed with bluish white pubescence on prosternum anterior to prosternal process, metaventrite, and abdominal ventrites. Legs, including tarsal dorsum, mostly clothed with bluish white pubescence, but with blackish pubescence on apical parts of femora and tibiae.

Mesosternal process without middle tubercle. Metaventrite with fine median sulcus. Metanepisternum wedge-like, distinctly narrowing posteriorly; anterior margin widely rounded; ventral margin gently incurved at anterior part.
Abdomen. Abdominal tergite VII (Fig. 3C) subhexagonal, widely and shallowly emarginate at posterior margin; tergite VIII (Fig. 4A) subhexagonal, distinctly and roundly emarginate at posterior margin, hardly depressed on dorsal surface (Fig. 4C). Abdominal sternites densely and finely punctate; sternite VII (Fig. 3D) subsemicircular, rounded at posterior margin; sternite VIII (Fig. 4B) with sclerotised area cordiform, distinctly emarginate at middle of posterior margin. Spiculum gastrale (Figs. 4D, E) with stem 2.2 times longer than branches; stem substraight, and strongly curved at base in lateral view (Fig. 4F).
Male genitalia. Tegmen (Figs. 5A, B) widest at middle, moderately curved ventrally in lateral view (Fig. 5C); ringed part moderately wide at base; parameres 1/4 length of tegmen, moderately elongate, gradually convergent towards round apex, apex with dense long setae (Fig. 5D). Median lobe (Figs. 5E, F) shorter than tegmen, gently curved ventrally in lateral view (Fig. 5G); dorsal plate (Fig. 5H) gradually narrowed towards apex, rounded at apical margin; ventral plate (Fig. 5H) longer than dorsal plate, widest just before base, significantly narrowed from subapex, and rounded at apical margin; basal struts (Figs. 5E, F) 3/8 length of median lobe.
Male paratypes. Body 21.8–28.5 mm long.All male types have the same body color, without evident variations. Very few specimens with rather tiny, sporadic maculae in basal 1/4 of elytra.
Female paratypes. Body 25.7–32.7 mm long, widest at about apical 4/9 (10.0 mm). Length of different body parts (n = 2, average value, mm): head (4.2), antenna (39.7), pronotum (4.0), elytra (20.7); width: head (5.9), pronotal apex (5.8), pronotal base (5.6), elytral humeri (9.2). Antennomeres with length ratio from base to tip: 5.08–1.00–8.10–6.74–5.41–4.54–4.70–3.86–3.59–3.19–3.98.
Similar to male in general appearance (Figs. 1C, D), but distinct by the following characters: antennae much shorter, about 1.4 times as long as body, with apical three antennomeres exceeding elytral apices; antennomeres with bluish white annulations considerably extending before apices; abdominal tergite VII (Fig. 3A) with small posterior apodemes, narrowly and roundly emarginate in middle of posterior margin; sternite VII (Fig. 3B) subtrapezoidal, narrowly and deeply emarginate in middle of posterior margins; sternite VIII (Fig. 6B) with sclerotised area bifurcate; tignum (Figs. 6A–C) about 12.3 mm, slightly sinuate, subequal in length to abdomen; spermatheca (Fig. 12A) long, slender, club-like; spermathecal gland (Fig. 12A) very long.
Etymology. The Latin adjective “ iadina ” means “emerald like”, referring to the emerald green elytral coloration of the new species. “ ṅAEk† (Pinyin: Fei Xing Tian Niu)” is proposed for the Chinese common name of this new species.
Host plant. Acer trees [DZRDzhv].
Field observations. Living female is shown in Fig. 13A and living pupa in pupal chamber is shown in Fig. 13B.
Distribution. China (Yunnan).
Differential diagnosis. Anoplophora iadina sp. nov. belongs to glabripennis species group, which including 7 known species: A. coeruleoantennata (Breuning, 1946), A. fanjingensis Yang, Yang & Tian, 2020, A. flavomaculata (Gressitt, 1935), A. freyi (Breuning, 1947), A. glabripennis (Motschulsky, 1854), A. puxian Wang & He, 2021, and A. rugicollis Wang, Xie & Wang, 2022. The new species is most similar to A. freyi (Figs. 2C, G), A. puxian (Figs. 2D, H) and A. rugicollis (Figs. 2B, F), on account of their common characters: elytra shiny with metallic luster (A. coeruleoantennata, A. flavomaculata and A. glabripennis black or blackish without metallic luster) and antennae with pubescent annulations (A. fanjingensis uniformly black without pubescent annulations).
A. iadina sp. nov. vs A. freyi (Breuning, 1947): pronotum with transverse wrinkles in the new species, while smooth without wrinkles in the latter (Fig. 2A vs Fig. 2C); frons, genae, vertex, scape, pedicel and lateral parts of pronotum with some moderately long, suberect, blackish setae in the new species, while almost glabrous in the latter; antennae with different pubescence colors (more obvious in females).
A. iadina sp. nov. vs A. puxian Wang & He, 2021: pronotum with transverse wrinkles in the new species, while relatively smooth in the latter (Fig. 2A vs Fig. 2D); elytra with obviously different macula patterns, the row at the level of metacoxae transversely merged into a line in A. puxian (Fig. 2E vs Fig. 2H); antennae with different pubescence colors (more obvious in females).
A. iadina sp. nov. vs A. rugicollis Wang, Xie & Wang, 2022: transverse wrinkles on pronotum are clearer and denser in A. rugicollis (Fig. 2A vs Fig. 2B); elytra almost without maculae in basal 1/ 4 in the new species, while maculae substantially present in basal 1/ 4 in the latter (Fig. 2E vs Fig. 2F); elytral maculae very small in the new species, while obviously larger and subelliptical in in the latter (Fig. 2E vs Fig. 2F).
