Differential diagnosis. This new species is obviously related to A. kazantsevi , A. latissima sp. nov. and A. lobipennis but can be easily distinguished from all of them by the shape and the surface sculpture of its pronotum ( Figs 135, 140 vs. Figs 133, 138, 134, 139, 124–127, 129–132 ), shape of elytra ( Figs 202, 212 vs. Figs 201, 211, 199, 200, 193–198, 203–210 ); scape with one to three short white additional setae and a single long apical one ( Figs 57, 58 ) vs. glabrous in A. kazantsevi ( Figs 54, 55 ), A. latissima sp. nov. ( Fig. 56 ) and A. lobipennis ( Figs 51–53 ); white elytral pattern with relatively long thin and slightly curved apical and medial portion of middle band ( Figs 202, 212 ) vs. short drop-shaped apical portion of middle band in A. kazantsevi ( Figs 201, 211 ), A. latissima sp. nov. ( Figs 199, 200 ) and A. lobipennis ( Figs 193–198, 203–210 ); aedeagus with relatively long, conical, indistinctly curved apex with small terminal knob ( Figs 224 , 234 ) vs. short, slightly broadened apex with large rounded knob in A. kazantsevi ( Figs 222 , 233 ) and A. lobipennis ( Figs 220, 221 , 232 ) or lacking in A. latissima sp. nov. ( Fig. 223 ); internal sac with large, sharply curved mt ( Figs 241 , 255 , 262 ) vs. straight mt in A. kazantsevi ( Figs 239 , 253 , 260 ) and A. lobipennis ( Fig. 254 , 261 ), and very large BLR ( Figs 241 , 255 , 262 ) vs. small one in A. kazantsevi ( Figs 239 , 253 , 260 ) and A. lobipennis ( Figs 240 , 254 , 261 ).

Description. TL = 14.7–17.0 mm (mean = 15.78 mm, n = 13) in males, 15.9–17.2 mm (mean = 16.41, n = 9) in females ( Fig. 28 ); body slightly convex, especially in males, TL/BH = 3.93–4.19 (mean = 4.06, n = 7) in males, 3.71–3.83 (mean = 3.77, n = 2) in females ( Figs 274, 276 ).

Head metallic bronze with cupreous-green or coppery-bluish-green lustre on clypeus, frons and genae; glabrous, coarsely wrinkled, with thin dense but fine frontal furrows; orbital plates with 9–10 deep furrows; vertex widely and shallowly concave; HW/PW = 1.26–1.33 (mean = 1.3, n = 7) in males, 1.24–1.29 (mean = 1.27, n = 3) in females ( Figs 274, 278 ). Antennae projected posteriorly over basal quarter of elytra; antennomeres 1–4 metallic green with dull bronze-cupreous reflections; scape besides a single apical seta with one–three additional short white setae in basal half; antennomere 3 with eight–ten setae and antennomere 4 with seven–eight stout white setae except apical ones ( Figs 57, 58 ). Labrum transverse, LW/LL = 1.75–1.94 (mean = 1.82, n = 7) in males, 1.43–1.49 (mean = 1.45, n = 3) in females, unidentate, with nearly semicircular apical margin and small central teeth, with 5–11 (n = 26) submarginal setae ( Figs 95, 100 ).

Pronotum metallic bronze with distinct cupreous or cupreous-green reflections; practically quadrate, PW/PL = 0.94–1.04 (mean = 0.99, n = 10), deep wrinkled and indistinctly convex, with sparse irregular rows of white decumbent hairs along nearly straight lateral margins converging near the base as well as with the sparse group of the same hairs on apical lobe; anterior and posterior sutures shallow, posterior angles with two rounded impressions; midline distinct, bronze with bluish-green tinge in central portion and short apical and basal impressions ( Figs 135, 140 ). Thoracic segments deep bronze, glabrous, coarsely wrinkled ( Fig. 150 ). Legs metallic green with dull bronze reflections.

Elytra bronze with cupreous or golden-cupreous lustre, with numerous, dense diffused, small bluish-green punctures as well as with subhumeral, subsutural and double subapical rows of large golden-green setigerous pores; flattened, EL/EW = 1.66–1.78 (mean = 1.72, n = 7) in males, 1.69–1.72 (mean = 1.71, n = 3) in females; with long, moderately deep subapical sinuate notch. Shoulders narrow, sloping, EW/EHW = 1.59–1.70 (mean = 1.65, n = 7) in males, 1.70–1.79 (mean = 1.75, n = 3) in females; scutellum large, bronze; humeral group of series umbilicata consists of 7–9 large setigerous pores ( Fig. 150 ); epipleura bronze, broad. White elytral pattern presented by small faintly projected sub-humeral spot and relatively long, thin, slightly curved centro-apical portion of middle band; supra-apical dot absent ( Figs 28 , 202, 212 ).

Abdominal ventrites black, glabrous, shallowly wrinkled laterally, ventrite 1 and 2 with light greenish-bronze reflection, other ones with deep violet tinge.

Aedeagus relatively long, EL/AL = 2.09–2.29 (mean = 2.20, n = 9), with relatively long, conical, indistinctly curved apex and small terminal knob and narrow lateral flanks ( Figs 224 , 234 ). Internal sac low, with long semicircular mt, broad sh-ar and large BLR ( Figs 241 , 248 , 255 , 262 ).

Etymology. The name of a new species is derived from Greek “ alopex ”[ἀλώπηξ], meaning the “ fox ”, and Greek “ omma ”[ὄμμα], meaning the “ eye ”, because of a thin curved centro-apical portion of middle band looking like a fox eye.

Distribution. CHINA: Sichuan Province ( Fig. 280 ).
