Diagnosis. The wing pattern of Nephelobotys evenoralis is barely distinguishable from that of the other members of the genus Nephelobotys , and the male and female genitalia of this species are similar to those of N. nephelistalis , but distinguished by the following characters: ventral and dorsal processes of fibula acuminate (ventral process nearly triangular and dorsal process hooked in N. nephelistalis ); in the female genitalia, the ductus bursae broader than in N. nephelistalis and corpus bursae not wrinkled (corpus bursae weakly wrinkled in N. nephelistalis ), all of characters are presented in fig. 11 of present study, and Inoue (1982: pl. 308, fig. 3), Mutuura (1954: pl. VIII, fig. 47) and Munroe & Mutuura (1970: p. 299, figs. 10, 14).

Type series: 1 male, North China, Mr. Fortune’s collection of NHMUK ( Walker, 1859) .

Material examined. (3 ♂) KOREA: 3 ♂, Mt. Jirisan, Sancheong-gun, Gyeongsangnam-do, Republic of Korea , 25–28 VI 2001 (Bae et al.), genitalia slide no. INU-7665K, 7804K, 7805K .

Distribution. Korea, Japan, China, Russia (Sahalin), Vietnam, Myanmar.

Remarks. This species is newly combined in the genus Nephelobotys based on the morphological characters of the genitalia: in the male genitalia, finger-shaped uncus; nearly subspatulate valva, mostly setose, except in median area; ventral and dorsal processes of fibula are present; deciduous palmate cornuti in phallus; in the female genitalia, antrum is funnel-shaped, sclerotized; ductus seminalis connected near posterior end of the antrum; membranous ductus bursae; ovoid corpus bursae, with a rhomboidal signum; appendix bursae is present.
