Holotype: ♂, China, Sichuan Province, Qianjiang; 1750 m a. s. l.; 14 Jul. 1989; IZAS.
Diagnosis.
The new species closely resembles A. nigriceps but differs due to each elytron with five black spots in A. nigriceps ; in this new species each elytron has six black spots, and the aedeagus apex is rounded.
Description.
Male. Length 5.0 mm, width 3.2 mm.
Head, antennae, pronotum, scutellum, ventral surface of thorax, abdomen, and legs black, elytra yellow, each elytron with six black spots, base, middle and apex with one pair of spots.
Vertex finely and sparsely covered with punctures. Interocular space 2.1 × as wide as transverse diameter of eye. Interantennal space 1.6 × 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 with short hairs, antennomere 2 shortest, antennomere 3 approximately 1.2 × as long as second; antennomere 4 longest, approximately 1.5 × 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 2 × as wide as long, lateral border margined, widest at anterior 1/3; disc with transverse furrow, less distinct in middle; covered with several large punctures in furrow and with sparsely small punctures in other parts of pronotum.
Scutellum triangular, only on base sparsely covered with small punctures.
Elytra wider than pronotum, 0.7 × 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 punctures, partially arranged in ten rows in each elytron, the interstices of punctures in rows approximately 2.5 × as wide as the 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, two subtriangular incisions.
Aedeagus slender, parallel-sided, basally widened, apically rounded, in lateral view distinctly bent.
Etymology.
The species name refers to the black antennal color.
