Diagnosis. This species resembles Nephelobotys habisalis , N. apiculata sp. nov., and N. denticulatus in the yellow ground color and the brownish subterminal band of wings in appearance, but wingspan is much larger (27.0– 30.0 mm), blackish brown lines and stigmata are more distinct ( Fig. 4 ) in N. evenoralis . In the male genitalia, N. evenoralis differs from all other species in the genus by the ventral part of inside sella folded, distal protrusion of sacculus with dorsal margin slightly wavy ( Fig. 14 ).
