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).
