Nannoarctia takanoi, described by Jinhaku Sonan in 1934, is an endemic species of moth in the family Erebidae from Taiwan. It is probably extinct now; no specimens have been collected since World War II. The species was formerly known as Pericallia integra <small>Matsumura, 1931</small>, but specimens from Taiwan are not conspecific to those from the Philippines, where N. integra <small>(Walker, 1855)</small> occur.
