Diagnosis.

This species can be distinguished from other Chinese species by each elytron having five black spots, the pronotum with three obvious black spots. This species differs from A. omeiensis in the aedeagus being slightly widened at the middle, and the base expanded into a fan shape.

Redescription.

Male. Length 5.4-5.8 mm, width 3.6-3.8 mm.

Head, antennae, pronotum, elytra, and leg yellow; vertex, scutellum, and ventral surface of the body black, apical ventrite of abdomen yellow, pronotum with three black spots, one large black spot in the middle, and one small black spot on each side; each elytron with five black spots, middle and apex with one pair of spots and base with one spot.

Vertex finely and sparsely covered with punctures. Interocular space 1.4 × as wide as transverse diameter of eye. Interantennal space 1.3 × 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 1.6 × 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 corner; disc with transverse furrow, less distinct in middle; sparsely covered with several large punctures in furrow.

Scutellum triangular, finely covered with punctures.

Elytra: wider than pronotum, 0.78 × as long as body, 1.7 × as long as wide, epipleura wide at anterior 1/3, posteriorly gradually narrowing towards apex, dorsal surface slightly convex, regularly covered with large and deep punctures, partially arranged in ten rows on each elytron, the interstices of punctures 2 × as wide as diameter of punctures and lightly covered with small punctures.

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, slightly widened at middle, basally enlarged in a fan shape, apex pointed, in lateral view slightly bent.

Female. Length 5.6-6.0 mm, width 3.5-3.9 mm.

Antennae slightly thinner than in male, antennomere 2 shortest, antennomere 3 approximately 1.5 × as long as second; antennomere 4 longest, 1.3 × as long as antennomeres 2 and 3 combined; apical sternite without incisions.
