( Figs. 1E )

Description of holotype. Length: 5.3 mm. BODY. Shape: subparallel, Color (dorsally): unicolored. HEAD. Frons. Shape: markedly convex. Vertex. Shape: markedly convex, Medial impression: absent, Sculpture elements: rugae, Sculpture aspect: subparallel, Sculpture density: dense, Sculpture intensity: rough. Eyes. Size: smaller than 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, Maximal width: at middle, Anterior margin: subequal to posterior. Anterior lobe. Shape: arcuate, Width: broad, Position: at level with anterior angles. Posterior angles. Shape: obtuse, Apex: sharp. Disk. Impressions: lateral only. Prehumerus. Development: carinal, Shape: arcuate, Extent: to 1/2 of pronotal length, Anterior end: distant from lateral pronotal carina, Posterior end: joined with posterior pronotal angle or margin, Arc: weak. Lateral carinae. Convergence: moderate, Junction: absent, Narrowest point: at posterior angles, Modifications: submarginal carina posteriorly obliterate. ELYTRA. Color: unicolored, Humeral carina: absent. Apices. Arrangement: separate, Shape: arcuate. Pubescence. Presence: without discernible pubescence. STERNUM. Prosternal lobe. Distal margin: arcuately emarginate. Prosternal process. Shape: markedly dilated, Sides: arcuate, Angles: acute, Angles (tips): sharp, Disc: flat. Metasternum. Metasternal projection: impressed. ABDOMEN. Pygidium. Apical margin: arcuate. Sternal groove. Shape on apex of last ventrite: arcuate. LEGS.

Metatarsus. Length to metatibia: distinctly shorter. Metatarsomere 1. Length to following tarsomeres: longer than 2–3 but shorter than 2–4. GENITALIA. Ovipositor. Shape: markedly elongate.

Variability. Body length: 4.9–5.6 mm. The shape of elytral apices varies from widely separately arcuate to widely separately subtruncate. Sexual dimorphism. The species is known only from females.

Diagnosis. The species is very similar to A. komareki Obenberger, 1926 in the habitus, in the color, in glabrous elytra, and in small eyes, but it can be distinguished by evenly arcuate sides of pronotum which are not sinuate before posterior angles, and by the distinctly dilated prosternal process.

Type material. Type locality: Russia, Primorsky Krai, Anisimovka - 10 km env., altitude 250–1200 m, N43.17, E132.787. Type specimens. Holotype ♀, 1 ♀ PT ( EJCB): “ Russia, Primorsky Krai, Anisimovka- 10 km env., 17-30.vi. 2014, 250- 1200m, N43.17, E132.787, E. Jendek leg.”. Other paratypes. RUSSIA.

Distribution. RUSSIA: Primorye.

Etymology. Patronymic; the species is named in honor of Dersu Uzala (1849–1908), a Nanai trapper and hunter who worked as a guide for Russian explorer Vladimir Arsenyev on his expeditions to the forests of the Far East in the area of Ussuri in 1902.
