Diagnosis. Adult (Fig. 4) wingspan 16.0–24.0 mm. Calamotropha aureliella is similar to C. paludella (Hübner, 1824) externally. It can be distinguished by the cream to white forewing without a medial speckle; in the male genitalia, by the sacculus convex at base and with a small process at apex (Fig. 30); in the female genitalia, by the antrum inflated posteriorly and the corpus bursae without a signum (Fig. 52). In C. paludella, the forewing has a medial speckle; the sacculus is straight at base and lacks a process at apex (Fig. 43); the antrum is not inflated posteriorly and the corpus bursae has a fan-like signum (Fig. 63).

Distribution. China (Heilongjiang, Inner Mongolia, Liaoning), Central Asia, Europe, Japan, Russia.
