Diagnosis. The wing patterns of this species are similar to that of J. taiwanensis , but can be distinguished by the following characters: smaller than J. taiwanensis (length of forewing: 18–21 mm in male; 21–26 mm in female); the hindwing medial line is narrower, about twice width of the postmedial line, the postmedial line strongly protrudes inwards below M3. In the male genitalia, the gnathos median process is broader and semicircular; the juxta is asymmetrical, the left sclerotized process is triangular, about one-fifth length of the juxta, the right side is slightly sclerotized. In the female genitalia, the ductus bursae is longer and slender, almost equal to the length of the corpus bursae, weakly sclerotized; the signum is oval, bigger, bearing 19–26 small spines.

Distribution. China (Henan, Gansu, Anhui, Zhejiang, Hubei, Jiangxi, Hunan, Fujian, Guangdong, Hainan, Guangxi, Sichuan, Chongqing, Guizhou, Yunnan), Japan, North Korea, South Korea, Thailand.

Remarks. The shape of the signum of the female genitalia is variable among the specimens from different localities. The signum of the specimens from Mokan-shan, Zhejiang and Huangkengdeng, Fujian are more rounded than those from Xingshan, Hubei, but otherwise similar. There may be variation of the shape of signum among J. fuscaria fuscaria in different areas of China. However the number of specimens and collecting sites are too limited to solve this problem presently.
