Distribution. China (Beijing, Hebei, Henan, Gansu, Ningxia, Shanxi, Sichuan).

Diagnosis. This species is similar to A. (A.) albicomella Moriuti, 1969 [holotype examined], but it differs from the latter in the rust-fuscous forewing with the dorsal band extending to the end of the fold, and in the funnelshaped antrum and the ovate corpus bursae apparently narrower on distal half in the female genitalia. In A. (A.) albicomella the dorsal band on the ferruginous-brown forewing extends to the basal 1/3 of the dorsum, and the antrum is uniform in width and the corpus bursae elliptical in the female genitalia.

Etymology. The specific name is derived from the Latin longus, meaning long, and albus meaning white, referring to the long white dorsal band.
