Sphalerostola caustogramma is a moth in the Xyloryctidae family. It was described by Meyrick in 1927. It is found in New Guinea (New Ireland).

The wingspan is 16-17 mm. The forewings are white with some brown irroration towards the base of the costa and a rather broad dorsal streak of grey suffusion sprinkled dark brown from the base to near the tornus. There is an irregular thick very dark brown streak suffused whitish-ochreous beneath the cell from near the base to the angle and a triangular patch of pale grey suffusion streaked dark brown irroration on the veins from the end of the cell to the whole of the termen, but leaving the terminal edge white with a series of dark brown dots. The hindwings are rather dark grey.
