Nannoarctia integra (F. Walker, 1855) is an endemic species of moth in the family Erebidae from the Philippines. The species is often confused with N. takanoi (Sonan, 1934) (=integra Matsumura, 1931) from Taiwan. The forewings are dark brown with a wide and unbroken oblique light fascia running from the wingbase to the apex. The male is characterized by yellowish-white hindwings with a dark costal margin, and a small discal and two marginal spots mainly at the apex and tornus. In females, these spots are bright yellow and larger.
