Diagnosis.

This species can be distinguished from the other Chinese species by each elytron having two broad longitudinal black stripes, and the apex with two black spots. This species differs from A. pictus in the aedeagus being slightly narrowed in the middle, and the apex widened.

Redescription.

Male. Length 5.0-5.3 mm, width 3.0-3.2 mm.

Head, antennae, pronotum, elytra and legs yellow, vertex, scutellum and ventral surface of the body black, margin and apex of abdominal ventrite yellow, pronotum with a black spot in middle, each elytron with two longitudinal black stripes, and apex with one pair of black spots.

Vertex finely and sparsely covered with punctures. Interocular space 2 × as wide as transverse diameter of eye. Interantennal space 1.4 × as wide as transverse diameter of antennal socket. Frontal tubercles transverse, each separated by a deep furrow; antennae slender, 0.7 × as long as body; antennomeres 1-3 shiny; antennomeres 4-11 covered with pubescence, antennomere 2 shortest, antennomere 3 approximately 1.5 × 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 1.8 × as wide as long, lateral border margined, widest at posterior corners; disc with deep transverse furrow, covered with several punctures in furrow and with sparsely small punctures in anterior angle.

Scutellum triangular, smooth, impunctate.

Elytra: wider than pronotum, 0.75 × as long as body, 1.75 × 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 in each elytron, the interstices of punctures wider than diameter of punctures, approximately 2 × as wide as diameter of 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, slightly narrowed in middle, basally widened, apex widened, in lateral view strongly bent.

Female. Length 5.0-5.2 mm, width 2.8-3.2 mm.

Antennae slightly thinner than in male, antennomere 2 shortest, antennomere 3 approximately 1.6 × as long as second; antennomere 4 longest, 1.4 × as long as antennomeres 2 and 3 combined; punctures densely in groove of pronotum, the interstices between punctures equal to diameter of individual punctures, apical sternite without incisions.
