Watson, Fletcher & Nye (1980) stated:-
A junior homonym of Systropha Illiger, 1806, Magazin Insektenk. (Illiger) 5: 145, - Insecta, Hymenoptera. There is no objective replacement name but the type-species of Systropha Hübner is currently considered to be congeneric with the type-species of Eilema Hübner, . The latter is therefore available for use as a subjective replacement name.

The objective replacement name is Wittia Freina, 1980.
Strysopha was also proposed as a replacement name for the preoccupied name Systropha Hübner, 1816, nec Illiger, 1806, (Hymenoptera) by Arora & Chaudhury, 1982, Zoological survey of India Technical Monograph (6) : 27.
This is an unnecessary replacement name as Wittia had already been given as the replacement name in 1980.
