The Agonoxeninae are a subfamily of moths.
Formerly, the subfamily only contained four named species – all in the type genus Agonoxena – if (e.g. following Nielsen et al., 1996). Such a monotypic arrangement is fairly unusual in modern taxonomy without explicit need due to phylogenetic constraints.
Hodges (in Kristensen, 1999) retained the Blastodacnidae in the Agonoxenidae, giving a grouping of some 31 genera, and treating the whole as a subfamily Agonoxeninae of the grass-miner moths (Elachistidae). Collectively, the Agonoxenidae and "Blastodacnidae" are known as palm moths.
