Blastobasinae

The Blastobasidae are a family of moths in the superfamily Gelechioidea. Its species can be found almost anywhere in the world, though in some places they are not native but introduced by humans. In some arrangements, these moths are included in the case-bearer family (Coleophoridae) as subfamily Blastobasinae. The Symmocidae are sometimes included in the Blastobasidae (particularly if both are included in Coleophoridae) as subfamily or tribe.

In addition, the group around Holcocera is often separated as subfamily Holcocerinae (or tribe Holcocerini) from the Blastobasis lineage (which correspondingly become a subfamily, or a tribe Blastobasini). While this seems far more reasonable than some of the more extreme arrangements sometimes seen in Gelechioidea taxonomy and systematics, the relationships among Blastobasidae genera are not yet sufficiently studied to allow a well-supported subdivision of this family.
