Metanepisternum wedge-like; anterior margin rounded; ventral margin distinctly curved at anterior area and slightly wide at posterior area.

Abdomen. Abdominal tergite VII ( Fig. 3C ) subhexagonal, slightly emarginate in middle of posterior margin; tergite VIII ( Fig. 4A ) subhexagonal, almost straight at posterior margin, with two evident depressions flank midline of dorsal surface ( Fig. 4C ). Abdominal ventrites finely punctate; ventrite VII ( Fig. 3D ) subtrapezoidal, slightly emarginate at middle of posterior margin; ventrite VIII ( Fig. 4B ) with sclerotized area narrowly emarginate at middle of posterior margin, and laterally widened. Spiculum gastrale ( Figs. 5A–C ) with stem 2.1 times longer than branches; stem slightly curved except base in lateral view ( Fig. 5C ).

Male genitalia. Tegmen ( Figs. 6A–B ) widest at basal 3/7, moderately curved ventrally in lateral view ( Fig. 6C ); parameres 2/7 length of tegmen, moderately elongate, gradually convergent towards round apex, apex with long setae ( Figs. 6D ). Median lobe ( Figs. 7A–B ) longer than tegmen, moderately curved ventrally in lateral view ( Fig. 7C ); dorsal plate ( Figs. 7A, D ) rounded at apical margin; ventral plate ( Figs. 7B, D ) slightly longer than dorsal plate, rounded at apical margin; median struts ( Figs. 7A–B ) 2/5 length of median lobe.

Male paratypes. Body 25.3–25.8 mm long. All male types have the same body color, without evident variations.

Female paratypes. Body 25.2–25.5 mm long, widest at about apical 2/5 of elytra. Length of different body parts (n=2): head, 3.1; pronotum, 4.1; elytra, 17.9; width: head, 5.2; pronotal base, 5.0; elytral humeri, 8.2. Antennomeres with length ratio from base to tip: 7.50—1.00—12.00—10.17—7.83—6.78—6.83—5.94—5.72—5.22—6.28.

Similar to male in general appearance, but distinct by the following characters: antennae much shorter, about 1.5 times as long as body, with apical four antennomeres exceeding elytral apices ( Figs. 1C–D ); scape thinner ( Figs. 1C–D ); almost whole length of antennomere III and basal half of IV covered with pale bluish pubescence ( Figs. 1C–D ); elytral macula rows distinctly narrower ( Fig. 1C ); legs relatively thinner ( Figs. 1C–D ); abdominal tergite VII ( Fig. 3A ) and ventrite VII ( Fig. 3B ) deeply emarginate in middle of posterior margin; spermatheca ( Fig. 8A ) long, slender, L-shaped, undulate in lateral view ( Fig. 8B ).

Etymology. The specific epithet of the new species “puxian” is in reference to Samantabhadra Bodhisattva, one of the four great Bodhisattvas of Chinese Buddhism, whose ashram Mt. Emei is also the type locality of the new species. A noun in apposition.

Distribution. China (Sichuan).

Differential diagnosis. The new species is similar to Anoplophora freyi ( Breuning, 1947) ( Figs. 2A–D ) in general appearance, but they have different macula patterns on the elytra. Beside this, the new species is distinguishable from the latter by the combination of the following characters: in A. puxian sp. n.: frons, genae, vertex, scape and pedicel with long, sparse, blackish setae ( Figs. 1A–D ); pubescent annulations in about basal half of antennomere III, at extreme base of IV–X respectively, almost absent on XI ( Figs. 1A–D ); prothorax with many long blackish setae at lateral sides, umbilicated granules and rugosities obviously presented except central area ( Figs. 1A, C ); elytra slightly iridescent green with coppery sheen ( Figs. 1A, C ); male tergite VIII hardly emarginate at posterior margin ( Fig. 4A ), with two evident depressions flank midline of dorsal surface ( Fig. 4C ); male ventrite VIII with sclerotized area narrowly emarginate in middle of posterior margin, and broadened laterally ( Fig. 4B ); spiculum gastrale with stem slightly curved except base in lateral view ( Fig. 5C ); parameres relatively more slender ( Figs. 6D ); median lobe relatively thicker ( Figs. 7A–B ), moderately curved ventrally in lateral view ( Fig. 7C ); female abdominal ventrite VII concolor ( Fig. 3B ); spermatheca long, slender, “L”-like ( Fig. 8A ), undulate in lateral view ( Fig. 8B ).

While in A. freyi ( Breuning, 1947) : frons, genae, vertex, scape and pedicel without long blackish setae ( Figs. 2A–D ); pubescent annulations in about basal 1/3 of antennomeres III–IV respectively, in about basal half of V–X respectively, at extreme base of XI in male or in about basal 2/5 and apical 1/3 of XI in female ( Figs. 2A–D ); prothorax with only several long brownish setae after lateral spines of lateral sides, only a few umbilicated granules and rugosities presented except central area ( Figs. 2A–D ); elytra slightly iridescent violet, copper, or blue sheen ( Figs. 2A, C ); male tergite VIII distinctly emarginate at posterior margin ( Fig. 4D ), with two vague depressions flank midline of dorsal surface ( Fig. 4F ); male ventrite VIII with sclerotized area widely emarginate in middle of posterior margin, and narrowed laterally ( Fig. 4E ); spiculum gastrale with stem moderately curved except base in lateral view ( Fig. 5F ); parameres relatively stouter ( Figs. 6H ); median lobe relatively thinner ( Figs. 7E–F ), weakly curved ventrally in lateral view ( Fig. 7G ); female abdominal ventrite VII bicolor, yellow in lateral areas ( Fig. 3F ); spermatheca short, stout, oval ( Fig. 8C ), curved in lateral view ( Fig. 8D ).
