Syllepte rogationis is a moth in the Crambidae family. It was described by Hampson in 1918. It is found in Mozambique. The forewings are yellowish white, the costal area to the postmedial line, the inner margin (except towards base) and the terminal area red-brown. There is a diffused incurved red-brown subbasal line and the antemedial line is red-brown, oblique to the median nervure. There is a red-brown spot in the middle of the cell and a discoidal bar. The median nervure towards the extremity and a patch beyond the lower angle of the cell are red-brown, as is the postmedial line. This line is excurved between veins 5 and 2, then retracted to the lower angle of the cell and excurved to the inner margin. The inner edge of the red-brown terminal area is waved, excurved between veins 5 and
