Variability. This species is known only from the female holotype.

Diagnosis. By having bicuspidate elytral apices, A. mimicus resembles species related to A. albogaster Deyrolle, 1864 . It differs by the markedly longer pronotum when compared to the elytra, by the rough sculpture of the head and pronotum, and by the camouflaging pattern of the elytral pubescence.

Type material. Type locality: Laos, Louang Namtha province, Namtha—Muang Sing, 21°09'N, 101°19'E, altitude 900–1200 m. Type specimens. Holotype ♀ (EJCB): “ Laos, Louang Namtha pr., 21°09'N, 101°19'E, Namtha—Muang Sing, 5–31.v.1997, 900– 1200 m, Vit Kubáň leg.”.

Distribution. LAOS: Louang Namtha. Etymology. The specific name mimicus (mimic) is the Latin adjective referring to the camouflage-like appearance of this species.
