The Agonoxenidae family of moths only contains four named species in the whole world (if, following Nielsen et al (1996) the Blastodacnidae are considered to be a separate family) :
Hodges, in Kristensen (1999) retained the Blastodacnidae in the same taxon as the Agonoxenidae giving a grouping of some 31 genera, but treated the whole as a subfamily of the Elachistidae.
