Lateral spine stout, with subacute apex laterally directed and slightly retrousse. Posteromedial callus moderately developed and elevated. Surface with some coarse punctures between lateral spine and posteromedial callus. Scutellum lingulate, rounded at apex. Surface micropunctuated. Elytra semi-oval, 2.1 times as long as humeral width, widest just after humeri. Humeral width 1.6 times wider than pronotal base. Lateral margin almost gradually narrowing towards conjointly rounded apices; sutural angle round. Surface with granules in about basal 1/3, sparsely covered with coarse punctures, interstices microreticulate.

Legs. Femora moderately stout; metafemora reaching posterior margin of abdominal sternite VI. Tibiae moderately long; protibiae gently incurvate around apical 1/3; meso- and metatibiae straight. Tarsomere I the longest, but not longer than II+III; III deeply bilobed.

Ventral side. Prosternum smooth; prosternal process almost smooth, slightly emarginate at apical margin. 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. 8C ) subrounded, shallowly emarginate at posterior margin; tergite VIII ( Fig. 9A ) subhexagonal, slightly emarginate at posterior margin, distinctly depressed on dorsal surface ( Fig. 9C ). Abdominal sternites densely and finely punctate; sternite VII ( Fig. 8D ) subtrapezoidal, almost straight at posterior margin; sternite VIII ( Fig. 9B ) with sclerotised area cordiform, distinctly emarginate at middle of posterior margin.

Length of different body parts (n = 2, average value, mm): head (2.3), antenna (24.6), pronotum (3.1), elytra (13.8); width: head (4.3), pronotal apex (4.2), pronotal base (4.3), elytral humeri (6.2).

Similar to male in general appearance ( Figs. 7C, D ), but distinct by the following characters: body somewhat larger; antennae much shorter, about 1.3 times as long as body, with apical two antennomeres exceeding elytral apices; abdominal tergite VII ( Fig. 8A ) with large posterior apodemes, widely and roundly emarginate in middle of posterior margin; sternite VII ( Fig. 8B ) subtrapezoidal, distinctly and subtriangularly emarginate at posterior margin; sternite VIII ( Fig. 11B ) with sclerotised area suboblong; tignum ( Figs. 11A–C ) about 7.8 mm, distinctly sinuate in lateral view, shorter than abdomen; spermatheca ( Fig. 12B ) short, stout, globular. spermathecal gland ( Fig. 12B ) relatively short.

Etymology. The Latin adjective “ zibroides ” means “zebra like”, referring to the banded color pattern of the elytra of the new species. “ ṀḦAEk† (Pinyin: Ban Ma Xing Tian Niu)” is proposed for the Chinese common name of this new species.

Host plant. Symplocos trees [ƜOiRDzhv] ( Fig. 13D ).

Field observations. Living female is shown in Fig. 13E and habitat at Shilipingtan is shown in Fig. 13C .

Distribution. China (Hunan and Guangxi).

Differential diagnosis. Anoplophora zibroides sp. nov. belongs to bowringii / lurida / beryllina species group. The larger size, the present of pale annulate antennomere bases, the large cicatrix of scape, and the irregularlysized and spaced elytral granules distinguish the new species from A. lurida (Pascoe, 1857) , and these characters are shared with A. beryllina (Hope, 1840) and A. bowringii (White, 1858) . A. zibroides sp. nov. with lateral spines of pronotum distinctly stouter, directing laterally; basal granules of elytra distinctly sparser. While the latter two species with lateral spines of pronotum somewhat more slender, directing lateroposteriorly; basal granules of elytra distinctly denser. Moreover, the new species has greyish white to bluish white pubescence, while most A. bowringii has blue pubescence with turquoise being less common and A. beryllina has turquoise pubescence being more common. And the new species has 3–4 glabrous rows on the elytron, while A. beryllina commonly has 8 rows, and A. bowringii has 5–6 rows.
