Nannoarctia takanoi

Nannoarctia takanoi (Sonan, 1934) is an endemic species of moth in the family Erebidae from Taiwan. It is probably extinct now; no specimen were collected after II World War. The species was formerly known as Pericallia integra Matsumura, 1931, but specimens from Taiwan are not conspecific to those from the Philippines, where N. integra (F. Walker, 1855) occur.

The forewings are blackish with narrow oblique light fascia abutting on the apex and with a subapical spot mostly narrower than its length. The hindwings are yellow with discal and submarginal, sometimes confluent, black spots.
