Syllepte angulifera is a moth in the Crambidae family. It was described by Druce in 1895. It is found in Guatemala, Costa Rica, Panama and Mexico. The forewings and hindwings are hyaline-white, the former crossed near the apex by a narrow brownish line, which almost reaches the anal angle and then turns inwards along the inner margin. The hindwings have a narrow V-shaped brownish line below the middle, which does not touch either margin.
