Diagnosis.

This species is very similar to C. lubricosa in appearance, but its greyish brown wings and body are darker than those of C. lubricosa . It also can be distinguished by the stout phallus, which has two fusiform cornuti decorated with numerous minute spines, and the ductus bursae, which is elongated and far more slender than that of C. lubricosa .

Description.

Male genitalia (Fig. 4C ). Valva square, with sparse setae. Saccus broad. Phallus stout, two fusiform cornuti decorated with numerous minute spines ( Inoue 1963).

Female genitalia (Fig. 4D ). Apophyses anteriores as long as apophyses posteriores. Antrum sclerotized. Ductus bursae long, membranous. Corpus bursae elliptical, taper distally, with a pair of narrow, longitudinal, band-like signa.

Distribution.

China (Chongqing, Fujian, Guangdong, Guangxi, Guizhou, Hubei, Sichuan, Zhejiang), Japan, South Korea.

Remarks.

There are occasionally some spines scattered in the ductus bursae of female specimens, which suggests that the cornuti in the male genitalia are deciduous (Fig. 4D ).
