Differential diagnosis. A new species is recognized from related A. kazantsevi (males only) by the wider labrum LW/LL = 2.14–2.56 (mean = 2.35) vs. 1.67–2.0 (mean = 1.86), by the wider elytra EW/EHW = 1.71–1.78 (mean = 1.75) vs. 1.53–1.69 (mean = 1.62) with more rounded lateral margins and shorter subapical notch (Figs 199, 200 vs. Fig. 201), by more convex body TL/BH = 4.0–4.28 (mean = 4.14) vs. 4.15–4.59 (mean = 4.31) and by the shape of aedeagus (Fig. 223 vs. Fig. 222).
Description. TL = 14.9–16.4 mm (mean = 15.6 mm, n = 2) in males (Fig. 27); body relatively flat, slightly convex, TL/BH = 4.0–4.28 (mean = 4.14, n = 2) (Figs 274, 276).
Head metallic bronze with light bluish-green and golden-cupreous lustre on clypeus, frons, and anterior edge of genae; glabrous, coarsely wrinkled, with thin dense frontal furrows; orbital plates with 8–9 deep furrows; vertex widely concave especially in anterior portion; HW/PW = 1.37–1.46 (mean = 1.41, n= 2) (Figs 274, 278). Antennae projected posteriorly over basal quarter of elytra; scape, except for single apical seta, glabrous; antennomeres 1–4 metallic bronze; antennomeres 3 an 4 with 4–5 white stout setae except apical ones (Fig. 56). Labrum transverse, LW/LL = 2.14–2.56 (mean = 2.35, n = 2) unidentate, with 4 submarginal setae (Figs 94, 99). Pronotum metallic bronze; slightly longitudinal, PW/PL = 0.88–0.94 (mean = 0.91, n = 2); wrinkled and practically flat on disc, with straight and converging to the base margins; anterior suture indistinct, posterior suture shallow with deep small pit basally; midline thin, golden-green (Figs 134, 139). Thoracic segments black with cupreous tinge, glabrous, coarsely rugose. Legs black, femora, and tibiae with cupreous reflections, tarsi with metallic green or blue-green reflections.
Elytra bronze-cupreous with numerous, densely diffused, small green punctures and with short sub-humeral and long sub-sutural row as well as sub-apical cluster of large green setigerous pores, flattened, EL/EW = 1.63–1.70 (mean = 1.67, n = 2), with deep but relatively short subapical sinuate notch. Shoulders narrow, distinctly sloping, EW/EHW = 1.71–1.78 (mean = 1.75, n = 2); scutellum bronze and wrinkled; epipleura broad, blackish-cupreous. White elytral pattern presented by small, rounded sub-humeral spot and rounded or indistinctly comma-shaped apical portion of middle band, apical dot entirely absent (Figs 199, 200).
Abdominal ventrites glabrous, blackish-cupreous.
Aedeagus medium-sized, EL/AL = 1.88–2.04 (mean = 1.96, n = 2), with bluntly extended apical tip and extended lateral flanks (Fig. 223).
Female unknown.
Etymology. The species is named " latissima " because of its wide elytra.
Distribution. CHINA: Yunnan Province (Fig. 280).
