Oenochroa and Artiastis (genera)
Oenochroa have some common small "grey" species with narrow wings. The forewing pattern may be very plain, or have various subtle streaks and dark spots/patches that are sometimes distinctive for a species. The hindwings vary from off-white through yellow and orange to quite dark grey. Artiastis are smaller moths that are very similar superficially, although generally having shorter palpi.
