Ametropalpis vidua is a moth of the family Erebidae first described by William Jacob Holland in 1894. It is found in Cameroon, Gabon, Rwanda and Uganda.[1]
The classification of this moth is disputed. Robert W. Poole (1989) treats it as a synonym of Ametropalpis though Martin Lödl (1996) excluded this species from Ametropalpis and Hypeninae and transferred the genus to Catocalinae.
The adults have a wingspan of 49–53 mm.[2]
