Diagnosis. Adult ( Fig. 4 View FIGURES 1–8 ) 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 View FIGURES 29–33 ); in the female genitalia, by the antrum inflated posteriorly and the corpus bursae without a signum ( Fig. 52 View FIGURES 51–55 ). In C. paludella , the forewing has a medial speckle; the sacculus is straight at base and lacks a process at apex ( Fig. 43 View FIGURES 40–45 ); the antrum is not inflated posteriorly and the corpus bursae has a fan-like signum ( Fig. 63 View FIGURES 61–64 ).
