Strepsigonia affinis is a moth in the family Drepanidae. It was described by Warren in 1897. It is found in Peninsular Malaysia and Borneo.[1]
The wingspan is about 27 mm. The forewings are pinkish ochreous with grey suffusion and two spots on the discocellular. There is a ferruginous wavy line, nearly vertical and before the middle. There is also a strongly dentate line at the middle of the costa, running out from veins 3 to 5 an inward again to the middle of the inner margin. The included space is pale rufous. There is a pale, lunulate submarginal line with dark grey shading on both sides and a dark spot between veins 6 and 7. The hindwings are the same as the forewings.[2]
