Diagnosis. Adult (Fig. 23). Wingspan 14.5–17.0 mm. Agonopterix septicella can be distinguished by the cuiller curved in S shape in the male genitalia (Fig. 45), and by the elliplical signum in the female genitalia (Figs 52, 52a). It can be hardly separated from A. heracliana (Linnaeus, 1758) in the male genitalia, but can be distinguished by the forewing without a white spot before the outer margin of the cell, which is present in A. heracliana (Huisman 2012: 85, fig. 14).

Distribution. China (Heilongjiang, Jilin), Russia, South Korea (Lvovsky 2001a).
