Systematics
Some other animal families, such as the
Dudgeoneidae,
Metarbelidae, and Ratardidae, have been included within this family time and again. The first is considered a distinct family of the
Cossoidea today recognizable by their
abdominal tympanal organs which the Cossidae lack, whereas the other two are usually kept in the Cossidae as
subfamilies. Some unrelated millers were included in the Cossidae in error, too, such as the genus ''
Holcoceroides'' which is more primitive
