Adult ( Fig. 9 ) wingspan 21.0– 33.5 mm . Calamotropha doii is similar to C. paludella Hübner, 1824 in genitalia. It can be distinguished by the valva distinctly concave at distal 2/5 on the ventral margin ( Fig. 35 ); in the female genitalia by the corpus bursae having one subrounded signum ( Fig. 56 ). In C. paludella , the valva is straight on the ventral margin ( Fig. 43 ), and the corpus bursae has one fan-like signum ( Fig. 63 ). Distribution. China ( Beijing , Hebei , Tianjin ), Japan .
