Diagnosis. Ashibusa flavalba is diagnosed by the forewings with two black spots along fold and one small black spot at the lower angle of the discal cell, and the broad white fascia from basal 1/5 and beyond middle of the costal margin reaching the dorsum respectively ( Zhang & Li, 2009: 337, fig. 3); in the male genitalia by the thornshaped dorsal process 1/4 the length of the right brachium, and the valvae widened in distal 1/4 ( Zhang & Li, 2009: 338, fig. 9); and in the female genitalia by the tubular sterigma with a tube-shaped process arising from the left side posteriorly.

Female genitalia ( Fig. 21 ) Apophyses posteriores 2.5 times length of apophyses anteriores. Sterigma tubular, with a slender tube-shaped process arising from left side posteriorly. Ductus bursae slightly longer than apophyses posteriores, membranous. Corpus bursae subelliptical, shorter than ductus bursae; entrance at posterior 1/5 of corpus bursae; signum being two rows of small denticles.

Distribution. China (Fujian, Guizhou, Zhejiang).
