Remark. In the original description of the species, Leech (1889) mentioned a female from Kiukiang and a male from Ningpo (Ningbo in Zhejiang Province), which are syntypes. In order to stabilize the nomenclature I hereby designate the female syntype from Kiukiang labeled as ‘Type’ as lectotype.

Diagnosis. The forewing length is 17–19 mm in males and 20–21.5 mm in females. The differences between C. phaedra , C. moupinensis and C. leechi are listed in the diagnoses of the latter two species.

Distribution. The species is known from Zhejiang, Fujian, Guangxi, Jiangxi, Hubei and Hainan Provinces of China.
