Variations. This species is widely distributed. The basal fascia is either present or absent. Specimens collected from Tianjin, Guizhou, Hunan, Sichuan, and Zhejiang have an obvious basal, medial and subterminal fasciae (Fig. 21), while the basal fascia is absent, and the medial and subterminal fasciae present or absent in the specimens collected from other localities (Fig. 21a).

Diagnosis: Adult (Figs 21, 21a) wingspan 23.0– 35.5 mm. Calamotropha paludella is similar to C. fulvifusalis (Hampson, 1900) externally. It can be distinguished from the latter by the rectangular valva in the male genitalia (Fig. 43), and the corpus bursae with one fan-like signum in the female genitalia (Fig. 63). In C. fulvifusalis, the valva is slightly narrower distally (Bleszynski 1961: Fig. 106), and the corpus bursae has one subrhombic signum (Bleszynski 1961: Figs 161, 162). In addition, this species is similar to C. aureliella (Fischer von Röslerstamm, 1834) and C. doii Sasaki, 1997 in appearance. However, they are significantly different in the male genitalia, and the differences between them are stated in the diagnoses of C. aureliella and C. doii .
