Symmetry: symmetric, Shape: widest in apical part. Variability. The species is known only from the male holotype . Diagnosis. The species resembles the common Palaearctic species A. viridis (Linné, 1758) in the habitus and glabrous elytra, and A. sinuatus (Olivier, 1790) in the color. It can be distinguished by smaller eyes, by obviously wide elytral apices, and by the shape of aedeagus ( Fig. 2F ). Type material.
