Spilomelinae is a very large subfamily of the lepidopteran family Crambidae, the crambid snout moths. They were formerly included in the Pyraustinae as tribe Spilomelini; furthermore taxonomists' opinions differ as to the correct placement of the Crambidae, some authorities treating them as a subfamily (Crambinae) of the family Pyralidae. If this is done, Spilomelinae is usually treated as a separate subfamily within Pyralidae. The Spilomelinae are believed to be polyphyletic. Many genera are only tentatively placed here even at this point.
