Sternal groove
. Shape on apex of last ventrite: arcuate. LEGS.
Metatarsus
. Length to metatibia: about as long or longer.
Metatarsomere 1
. Length to following tarsomeres: subequal or longer than 2–4. GENITALIA.
Aedeagus

Variability.
The species is known only from the male
holotype
.
Diagnosis.
The species is similar to
A. paralleloides
Jendek, 2011
from
China
in the size, in the color, in small eyes, in the subtriangular pubescence of apical third of elytra, in separately arcuate apices, and in the glabrous prosternal process in male. The new species can be distinguished by the obviously wide pronotum with markedly arcuate sides and by the arcuate sternal groove on apex of last ventrite.
