Paramilionia is a genus of moth in the family Geometridae. At present there is only one species in this genus: Paramilionia rubroplagata that was described from Sierra Leone. Although, there are some doubts about the labels of the types and this is possibly a synonyme of the South American Sangala gloriosa
