Diagnosis. This species can be distinguished by the following combined characters: the gray background color of the basal half of the forewing is densely suffused with brown scales; the presence of gray bands bordering the yellow central fascia of the forewing; the very narrow medial lobe of the valva; and the presence of a pair of strongly articulated carinae in the anellus at the base of juxta.

Specimen examined. Holotype ♂ in OPU.

Distribution. China (Taiwan).

Remarks. The type specimen was collected at about 1,800 m on the southern slope of Cuifeng, Taiwan, and several adults were observed swarming above the flowers of possibly Quercus glauca (Fagaceae) (Kozlov & Hirowatari 1997).
