Description of holotype. Length: 7.8 mm. BODY. Shape: subparallel, Build: robust, Profile: dorsally flattened, Color (dorsally): unicolored. HEAD. Vertex. Sculpture elements: rugae, Sculpture aspect: subparallel, Sculpture density: dense, Sculpture intensity: rough. Eyes. Size: subequal to half width of vertex (dorsal view), Lower margin: in line or below antennal socket, Median orbit: subparallel. Antennae. Serration: from antennomere 4. PRONOTUM. Shape: visually transverse, Sides: markedly arcuate, Sides (modification): sinuate before posterior angles, Maximal width: at middle, Anterior margin: subequal to posterior. Anterior lobe. Development: moderate, Shape: arcuate, Width: broad, Position: at level with anterior angles. Posterior angles. Shape: acute, Apex: sharp.
Disk. Impressions: lateral only. Prehumerus. Development: carinal, Shape: arcuate, Extent: to 1/3 of pronotal length, Anterior end: distant from lateral pronotal carina, Posterior end: joined with posterior pronotal angle or margin, Arc: weak. Lateral carinae. Junction: present, Narrowest point: at posterior 1/5–1/4 of marginal carina. ELYTRA. Color: unicolored, Humeral carina: absent. Apices. Arrangement: separate, Shape: arcuate. Pubescence. Extent: distal only, Distal (shape): perisutural stripe. STERNUM. Pubescence. Strip of erect pubescence: absent. Prosternal lobe. Size: large, Distal margin: arcuately emarginate, Emargination (depth): deep, Emargination (width): narrow. Prosternal process. Shape: subparallel, Sides: straight, Angles: obtuse, Angles (tips): blunt, Disc: impressed. Metasternum. Metasternal projection: impressed. ABDOMEN. Basal ventrite. Modifications: absent. Pygidium. Apical margin: arcuate. 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. Symmetry: symmetric, Shape: widest in apical part, Modifications: apex of medial lobe markedly obtuse.
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.
Type material. Type locality: Iran, Mazandaran, 10 km West of Gorgan, altitude 300 m. Type specimens. Holotype ♂ ( EJCB): “ Iran, Mazandaran, 10 km westlich Gorgan, 2- 3.6.1977, 300 m, leg. Holzschuh & Ressl”.
Distribution. IRAN: Mazandaran.
Etymology. The specific name is a noun in apposition and refers to the type locality.
