The species was known as
X. rhomboidea up to 1997. Since the taxonomic revision by Hacker in 1998, the name
Xestia stigmatica is in use and was used by Fibiger and Skuhle in 2004 as well as on
Fauna Europaea. The reason for the change is that
Phalaena Noctua rhomboidea as described by
Eugenius Johann Christoph Esper in 1790 is actually the
double square-spot (
X. triangulum), but Esper's name had been misapplied to the square-spotted clay. ==References==
