Imma acroptila is a moth in the family Immidae. It was described by Edward Meyrick in 1906.[1] It is found in Sierra Leone.[2]
The wingspan is 16–17 mm. The forewings are dark fuscous, mixed with glossy purplish slaty on the veins, in females mixed with ochreous between the veins. There is a short orange dash from the base, and a slender streak beneath the costa towards the base, as well as several small scattered orange spots and streaks in the disc. In females, there is an obscure submarginal orange-ochreous line from three-fourths of the costa to the tornus. The hindwings are dark fuscous.[3]
