Diagnosis. Adult ( Figs. 1, 2 ). Head, from above, cleft in front; genal processes short, obliquely truncate apically with small point near median body axis ( Fig. 5 ). Forewing ( Fig. 6 ) with relatively long Rs, distal portion of non-tracheate vein usually more than twice as long as basal portion; vein Cu1a relatively weakly curved; surface spinules present in the middle of cell c+sc, brown markings present at the apex of cell cu2, apical half of cell cu1, and near the posterior margins of cell m1 and cell m2. Paramere ( Figs. 7, 9, 11 ) with outer lobe on the middle of outer surface; apex of paramere twisted. Distal segment of aedeagus ( Fig. 10 ) with horn-shaped end tube of the ductus ejaculatorius at the apex. Female terminalia ( Fig. 8 ) massive with deeply sinuous circumanal ring; apex of subgenital plate short.

Fifth instar immature. Description by Li (2011).

Distribution. China (Anhui, Beijing, Chongqing, Fuzhou, Guizhou, Jiangsu, Jiangxi, Hebei, Henan, Hubei, Hunan, Liaoning, Shaanxi, Shangdong (type-locality ‘Tsingtau’), Shanxi, Sichuan, Zhejiang) ( Enderlein 1926; Li 2011); Japan (Honshu, Shikoku, Kyushu) ( Miyatake 1981; Miyatake & Inoue 2016); South Korea ( Kwon & Huh 1998).

Host plant. Firmiana simplex (L.) W. Wight ( Malvaceae ) ( Miyatake 1981; Kwon & Huh 1998; Li 2011). The immatures, particularly the older instars, secrete large amounts of flocculent wax and honeydew ( Figs. 3, 4 ).
