Ambia albiflavalis is an African moth in the family Crambidae. It was described by George Hampson in 1917.[1] The type locality is Nigeria.[2]
The wingspan is about 14 mm. The forewings are silvery white, the base is orange yellow with an oblique outer edge. There is an obliquely curved orange-yellow antemedial band. The end of the cell is tinged with brown and the fovea above it with two brown points on its upper edge. There is a yellow patch with a white spot on it beyond it on the costal area and an orange-yellow subterminal band defined at the sides by brown, obliquely curved to vein 2, then bent outwards to the tornus, giving off (on the inner side between veins 4 and 2) a yellowish fascia tinged with brown to the lower end of the cell. There is also a pale brown terminal band. The hindwings are silvery white with an orange-yellow antemedial band from the cell to the inner margin, as well as a curved orange-yellow postmedial band defined by red brown from the costa to vein 1, its outer edge angled outwards at vein 4. There is a sinuous orange-yellow subterminal band defined by red brown and ending at the tornus, its outer edge excurved at the discal fold to the narrow orange-yellow terminal band defined on the inner side by a red-brown line and ending at the orange-yellow band at the submedian fold.[3]
