Diagnosis.
This species can be distinguished from other species by each elytron with two longitudinal black stripes, and the apex with one black spot. This species differs from A. tianpingshanensis in the aedeagus apex being distinctly pointed; in lateral view the apex is moderately bent.
Redescription.
Male. Length 4.6-4.9 mm, width 2.5-3.0 mm.
Head, antennae, pronotum, elytra and leg yellow, vertex, scutellum, and ventral surface of the body black, pronotum with a black spot in middle, each elytron with two longitudinal black stripes, and apex with one black spot.
Vertex finely and sparsely covered with punctures. Interocular space 1.5 × as wide as transverse diameter of eye. Interantennal space 1.2 × 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, antennomeres 2 and 3 shortest, antennomere 3 nearly equal in length and shape to antennomere 2, 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 1.8 × as wide as long, lateral border margined, widest at posterior corners; disc with deep transverse furrow, covered with closely large punctures in furrow and with sparsely small punctures in other parts of pronotum.
Scutellum triangular, with rounded apex, smooth, impunctate.
Elytra: wider than pronotum, 0.75 × as long as body, 1.65 × 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 in rows 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 4, with two subtriangular incisions.
Aedeagus slender, parallel-sided, basally widened, apex distinctly pointed, in lateral view apex moderately bent.
Female. Length 4.4-5.0 mm, width 2.6-3.2 mm.
Antennae slightly thinner than in male, without short hairs, antennomere 2 shortest, antennomere 3 approximately 1.5 × as long as second; antennomere 4 longest, approximately 1.5 × as long as antennomeres 2 and 3 combined; apical sternite without incisions.
Distribution.
China: Gansu, Shaanxi.
