Diagnosis. See diagnosis of the following species, C. (C.) sapporella ( Matsumura, 1931) .

Description. Adult. Wingspan 9.0–11.0 mm. Head brown, face white or yellowish white. Maxillary palpus and labial palpus white. Labial palpus with distal part of third segment dark brown, sometimes ventral side of end of second segment slightly brown. Antennae brown, with black rings on flagellum. Thorax lemon yellow. Fore and mid legs dark brown, with base of fore coxa or whole of fore coxa yellowish white, fore and mid tarsus white and end of each segment slightly brown; hind legs yellowish white, base of coxa and lateral side of femur dark brown, end of tibia gray, sometimes end of each tarsal segment slightly brown. Tegula and forewing brown with purple luster, a rectangle lemon yellow spot occupying base to 1/4 of dorsum, which slightly narrower than half of wing width; a triangular lemon-yellow patch occupying costal 1/4 to 3/4, widest in middle of wing, about 3/4 of wing width, with 0–5 dark brown spots on costa; cilia on termen light brown, long scaly, with 2–3 dark brown lines, cilia on dorsum light brown. Hindwing and cilia gray. Abdomen light brown dorsally, yellowish white ventrally.

Male genitalia. Tuba analis broad, with a linear sclerotization at middle. Tegumen ligulate, slightly inflated distally, rounded on posterior margin, densely setose on both sides. Valva reniform, densely covered with long setae, apical margin densely covered with short setae. Vinculum + saccus V-shaped. Phallus shorter than valva, densely covered with micro spines on 3/5 to 1/5 of end. Two pairs of coremata present.
