Diagnosis. There is no species similar to R. rufimaculella, and it can be easily recognized by the unique wing pattern and the genitalia characters as follows: the antemedial line is bordered by reddish-yellow band distally; inner side of postmedial line with short reddish-yellow spot distally. In male genitalia, the gnathos is bifurcate, and the cornutus is formed by numerous thorn-shaped sclerites in aedeagus.
Adult (Fig. 1A). Wingspan 15-18 mm. Frons pale grayish-brown; labial palpus fuscous and upturned, 2nd and 3rd segment same length, inner side with white scales; maxillary palpus grayish-white, about 1/3 length of 3rd segment of labial palpus; proboscis covered with white scales; antenna fuscous, scape enlarged, dorsal part grayish-white. Thorax, patagium and tegula grayish-brown. Forelegs with femur white, tibia and tarsus fuscous; midlegs with femur and tibia white, mixed with brown, tarsus pale brown; hindlegs with femur and tibia white, mixed with brownish-gray scales, tarsus pale brown, inner side and tip with pale gray scales. Forewing with ground color brownish-gray; antemedial line grayish-white, straight, oblique outwardly from 1/3 of costa, bordered distally by broad reddish-yellow band; postmedial line grayish-white, sinuous, inside distally bordered by short reddish-brown spots; median area with grayish scales near costal area; distal discoidal spots two, fuscous; terminal grayish- white, interneural spots black, subterminal area suffused with gray scales; fringe pale grayish-brown. Hindwing pale gray, terminal line and fringe pale brown.
Male genitalia (Fig. 2A). Uncus semicircular; gnathos bifurcate apically, each arm finger-shaped, slightly longer than uncus, rounded in the end; transtilla connected as rectangular, terminal margin rather flat; valva rounded at apex, costa enlarged as triangular; sacculus about 2/3 length of valva; juxta U-shaped, lateral lobes as long as gnathos; vinculum rather short; saccus rounded; aedeagus short, about 1/2 length of valva, narrow at apex, cornutus formed by numerous thornshaped sclerites.
Female genitalia (Fig. 3A). Apophyses anteriores stout, about 1/2 length of apophyses posteriores; antrum cup-shaped, well-sclerotized; ductus bursae rather short; corpus bursae oblong, about 4 times as long as antrum; signum well-sclerotized, rather big, coniform, basal part enlarged.

Diagnosis. This species can be distinguished from C. infusella by the following characteristics: in the male genitalia, the sacculus with uniformly distributed setae; aedeagus curved; in the female genitalia, the signum peanut-shaped, near the middle of corpus bursae. As for C. infusella, in the male genitalia, the setae of sacculus not arranged in groups; aedeagus straight; in the female genitalia, the signum small and rounded, near the bottom of corpus bursae.
Adult (Fig. 1B). Wingspan 19-21 mm. Frons fuscous; vertex yellowish-brown, covered with long scales; labial palpus fuscous, slender and upturned, 2nd segment about 1.5 times of 3rd segment in length; maxillary palpus brownish-gray, slightly shorter than the 2nd segment of labial palpus; proboscis fuscous basally; antenna filiform and pale brown, less than 1/2 of the forewing, male scape swollen, and with 2 tooth-like projection. Patagium and tegula grayish-brown. Forelegs fuscous; midlegs fuscous, with tip of tibia grayish-white; hindlegs with femur and tibia grayish-white, tarsus pale gray. Forewing with ground color gray; antemedial line white, slightly convex outwardly, outside the line with dark band; postmedial line oblique from costa inwardly, convex outwardly in middle, postmedial line border with fuscous line on both sides; distal margin with a serious of black spots; apex tinted with dark brown; fringe pale brown. Hindwing pale white, without spots, fringe pale brown.
Male genitalia (Fig. 2B, C). Uncus triangular, slightly flat on top, lateral sides with hairs; gnathos slender, with sharped tip, about 1/2 length of uncus; distal part of valva with hairs, costa well-developed, broad at base 1/2; harpe at base of valva; sacculus sclerotized, about 1/2 length of valva, with thin bristles; juxta V-shaped, lateral lobe well-developed (Fig. 2C); vinculum U-shaped, length slightly longer than greatest width, terminal margin concave; aedeagus stout, cylindrical, slightly curved, cornutus absent.
Female genitalia (Fig. 3B). Apophyses anteriores and posteriores slender, almost equal; ostium bursae broad, sclerotized slightly; ductus bursae about 1.3 times as long as corpus bursae, posterior with granulated ventral surface; corpus bursae oval, membranous, signum peanut-shaped, in the middle of corpus bursae, composed of minute spines; ductus seminalis from the end of ductus bursae.
