Redescription. Forewing length 9–13 mm (n=14). Head, thorax, and abdomen covered with pale brown to brown scales. Antenna stem reddish brown, with yellowish brown rami. In males, antenna bipectinate, gradually tapering at the tip; female antenna filiform. Labial palpus short, close to vertex, 1 st segment curved upward, black brown; 2nd segment bent at a right angle from the 1st, stout and relatively longer, almost three times as long as that in the 1st, black brown; 3rd oval, pale brown. Legs yellowish to black brown, hind tibia with one pair of spurs and with long, dense hair. Forewing red brown to dark brown in basal two-thirds and pale reddish brown in outer one-third. Reddish scales present at costa and wing base in basal two-thirds; white scales form an obscure band extending from costa to vein CuA 2 in outer one-third. Fringes yellowish brown. A black postdiscal fascia runs straight from costa to vein CuA1, turning slightly outward and extending at an anal angle. Black scales concentrate in spaces 1A+2A, CuP, CuA2, discocellular vein, and center of the cell, and form two similar, prominent black spots. Hindwing generally yellowish; brown scales scattered in basal half and concentrated at the anal angle. In forewing venation ( Fig. 9 ), length of discoidal cell almost equal to 1/2 forewing length, Sc ends 2/3 forewing length, R1 and R2 almost parallel with each other, R3 extending to apex, R3 and R4 branch from R5 forming a common stem, R4 and R5 extending to termen; M1 almost parallel to M2, and M2 closer to M3 than to CuA1. In hindwing ( Fig. 10 ), Rs and M1 stalked, 1A and 2A stalked near base, and 1A+2A and 3A nearly parallel.

Male genitalia ( Fig. 5 ). Uncus large, with distal end bilobed, tapering to apex and much slender, not extending into rounded ends on both sides, rectangular caudally; subuncus bears one pair of triangle processes. Gnathos consists of two branches, paired branches claw-shaped apically and connected to each other by long and narrow bridge medially. Tegumen broad. Valvae deeply concave in the middle, dorsal part of the valvae oval, with setae at the tip, base of dorsal bears finger-shaped process; ventral part of the valvae nearly triangular, bearing setae from tip to base. Juxta upper bow-shaped, bottom with two small triangular and one semicircular processes. Saccus simple, V-shaped. Aedeagus slender, with the distal tip bending nearly 90° upward.

Female genitalia ( Fig. 6 ). Papillae anales flattened, rounded apically. Posterior apophyses developed and slender; anterior apophyses small and short, thorn-like. Ductus bursae thick, not spiral; corpus bursae rounded and relatively large.

Remarks. According to previous studies ( Solovyev 2008, 2010), the morphological characters described above are those of C. banghaasi . The wing pattern and male genitalia described by Wu & Fang (2010) and Li (2012) indicates that “ C. banghaasi from Henan ” is C. houshuaii .

Larvae ( Fig. 15 ) are of the nettle-type, with long scoli, dorsum and two sides each with one row of segmental blue-black rectangular spots. The center of dorsum marked with a white-centered bluish patch, which ringed with black and follows by two longitudinal orange red patches. An outer black ring encircles these patterns and two orange red patches present laterally to the outer black ring.

Food plants. Burseraceae : Canarium album (Lour.) DC.; Cupressaceae : Fokienia hodginsii (Dunn) A. Henry & H.H. Thomas.
