Diagnosis. Wing expanse 13.0–16.0 mm. This species is superficially similar to E. angustana, but can be distinguished by two features of the male genitalia: the subquadrate valva and the longer aedeagus, twice the length of valva. In E. angustana the valva is subtriangular; and the aedeagus is about 1.25 times length of valva (Fig. 2 c). Eupoecilia inouei is also similar to E. ambiguella, sharing a broad subquadrate valva in the male genitalia, but it can be distinguished from the latter by the anterior portion of the forewing median fascia being as broad as the posterior portion (Fig. 1 e); the sacculus without spines in the male genitalia (Fig. 3 b); and the ductus bursae broaden posteriorly in the female genitalia (Fig. 4 d). In E. ambiguella the anterior portion of the median fascia is broader than the posterior portion (Fig. 1 b); the sacculus has spines at the apex (Fig. 2 b); and the ductus bursae is not broaden posteriorly (Fig. 4 b).
