Chrysophyllis is a genus of the grass moth family (Crambidae). It is monotypic, containing the single species Chrysophyllis lucivaga. This moth is very little known, having only been recorded once, before 1935. It belongs to the large grass moth subfamily Spilomelinae; at the time of its description, these were still included in subfamily Pyraustinae and the entire Crambidae was then merged with the snout moths (family Pyralidae). While its exact relationships are undetermined, it is believed to be a close relative of Talanga (but see below). Like these (and some other, unrelated, moths), the male genitalia of C. lucivaga feature a remarkably elongated aedeagus shaped like a bullwhip.
