Differential diagnosis. From nominotypical subspecies A. bivirgulata occidentalis ssp. nov. is distinguished by the narrower white elytral pattern ( Figs 155–162 vs. Figs 173–179 and Figs 165–172 vs. Figs 183–189 ) and by more convex body ( Fig. 273 ; Table 2 ).

Description. TL = 15.1–17.4 mm (mean = 16.6 mm, n = 26) in males, 15.6–18.9 (mean = 17.4, n = 24) mm in females ( Figs 12–15 ); body convex, in females much better than in males—TL/BH = 3.29–3.9 (mean = 3.51, n = 22) vs. 3.48–4.24 (mean = 3.75, n = 26) ( Fig. 277 ; Table 2 ).

Head bronze or cupreous-bronze with purple, purple-green, or golden-green lustre, gula black-bronze with cupreous-green or greenish-gold reflection; orbital plates with 6–9 relatively deep furrows; vertex widely concave, with shallow impressions anteriorly; in females wider than in males—HW/PW = 1.18–1.35 (mean = 1.27, n = 22) vs. 1.22–1.41 (mean = 1.32, n = 26).

Antennae in males projected posteriorly over basal third while in females over basal quarter of elytra; antennomeres 1–4 metallic green with cupreous, bronze-cupreous or golden-cupreous reflection, scape besides single apical seta glabrous; antennomeres 3 with 5–12 while antennomere 4 with 3–7 short, stout white setae except apical ones ( Figs 42–48 ). Labrum transverse, LW/LL = 1.79–2.44 (mean = 2.2, n = 26) in males, 1.64–2.08 (mean = 1.9, n = 24) in females; unidentate, with long stout apical tooth in females and short tooth in male, with 4–8 submarginal setae ( Figs 73–82 ).

Pronotum bronze or cupreous-bronze with golden-green, purple-curpic tinge, or cupreous-green with golden reflection; from indistinctly longitudinal or quadrate in males to nearly quadrate in females—PW/PL = 0.91–1.0 (mean = 0.95, n = 26) vs. 0.97–1.05 (mean = 1.0, n = 24); with lateral margins slightly converging to the base; coarsely wrinkled, indistinctly convex; anterior suture indistinct, posterior suture shallow; midline thin but clearly visible, metallic bluish-green or green with small deep impression basally ( Figs 113–122 ). Thoracic segments deep bronze, with light greenish, purple, or purple-cupreous lustre, glabrous, coarsely rugose. Legs metallic bronze or bronze-green with dull cupreous, cupreous-green, or golden-cupreous tinge.

Elytra bronze or bronze-green with cupreous or greenish-cupreous tinge, with numerous, dense diffused, small bluish-green punctures and subhumeral and subsutural rows, as well as subapical diffuse cluster of large golden-green setigerous pores; in males narrower than in females—EL/EW = 1.6–1.78 (mean = 1.71, n = 26) vs. 1.45–1.7 (mean = 1.61 mm, n = 24); with poorly developed or practically undeveloped, shallow subapical notch, especially in females; apices in females distinctly wider than in males. Shoulders narrow and sloping, EW/EHW = 1.46–1.72 (mean = 1.57, n = 50); scutellum large, bronze or bronze-cupreous with cupreous or cupreous-green tinge; humeral group of series umbilicata consists of 8–12 large setigerous pores; epipleura broad, dark bronze with purple lustre. White elytral pattern presented by extremely small sub-humeral spot lacking in some specimens, by transverse, small or small drop-shaped transverse or slightly oblique apical portion of middle band surrounded by black halo ( Figs 173, 174, 177–179, 184, 185, 187–189 ), and rarely by small supra-apical ( Fig. 175 ) spot sometimes replaced by triangular, dark brown patch ( Fig. 176, 183, 186 ).

Abdominal ventrites black or dark bronze with violet or bluish-green tinge especially along finely striated lateral margins.

Aedeagus medium-sized, EL/AL = 1.84–2.17 (mean = 2.01, n = 23), with slightly curved, short proximal portion and short, straight rounded apex with long lateral flanks ( Figs 216–219 , 230, 231 ); internal sac with large, slightly curved mt ( Figs 269–272 ).

Etymology. The new subspecies is named after its western distribution area.

Distribution. CHINA: Gansu, Shaanxi, Henan, Shanxi, Sichuan Provinces, Inner Mongolia Autonomus Region ( Fig. 280 ).
