Diagnosis.

This species can be distinguished from other Chinese species by its purplish blue elytra, and the apex of the pronotum without a raised area. This species differs from A. chalybeus in the pronotum being widest at its posterior corners.

Redescription.

Male. Length 9.0-10.8 mm, width 4.8-5.2 mm.

Head, antennae, pronotum, scutellum and ventral surface of body yellow, legs brown with femur yellow, elytra purplish blue.

Vertex covered with several large punctures. Interocular space 1.65 × as wide as transverse diameter of eye. Interantennal space 1.4 × as wide as transverse diameter of antennal socket. Frontal tubercles distinctly raised, hook-like, each separated by a deep furrow; antennae slender, 0.75 × as long as body; antennomeres 1-3 shiny; antennomeres 4-11 covered with pubescence, antennomere 2 shortest, antennomere 3 twice as long as second; antennomere 4 longest, approximately 1.8 × as long as antennomeres 2 and 3 combined; antennomeres 5-10 gradually shortened, shorter than antennomere 4; antennomere 11 slightly longer than antennomere 10, pointed.

Pronotum approximately 2 × as wide as long, lateral border margined, widest at posterior corners; middle of disc with transverse furrow; closely covered with large punctures in furrow and with sparsely small punctures in other parts of pronotum.

Scutellum triangular, smooth, impunctate.

Elytra: wider than pronotum, 0.8 × as long as body, 1.7 × as long as wide, epipleura wide at anterior 1/4, posteriorly gradually narrowing towards apex, dorsal surface slightly convex, irregularly covered with large punctures, the interstices of punctures wider than diameter of individual punctures, approximately 2 × as wide as diameter of individual punctures and lightly covered with small punctures in interstices.

Metasternum 2 × as long as the mesosternum. Ventral surface of abdomen with five ventrites, ventrite 1 longest, ventrites 2-4 gradually shortened, apical ventrite slightly longer than ventrite 3, with two subtriangular incisions.

Aedeagus slender, parallel-sided, basally widened, narrowed in middle, apex distinctly pointed, in lateral view base and apex distinctly bent.

Female. Length 8.8-10.6 mm, width 4.6-5.4 mm.

Antennae slightly thinner than in male, antennomere 2 shortest, antennomere 3 approximately 1.5 × as long as second; antennomere 4 longest, 1.5 × as long as antennomeres 2 and 3 combined; apical sternite without incisions.
