The Elachistidae are a family of small moths in the superfamily Gelechioidea. Some authors lump about 3,300 species in eight subfamilies here, but this arrangement almost certainly results in a massively paraphyletic and completely unnatural assemblage, united merely by symplesiomorphies retained from the first gelechioid moths.
Gelechioidea is the superfamily of moths that contains the case-bearers, twirler moths, and relatives, also simply called curved-horn moths or gelechioid moths. It is a large and poorly understood '"micromoth" superfamily, constituting one of the basal lineages of the Ditrysia.
The Ethmiinae are a subfamily of small moths in the superfamily Gelechioidea sometimes included in the Elachistidae or the Oecophoridae, but mostly in the Depressariidae as a subfamily Ethmiinae.
Alabonia geoffrella is a species of gelechioid moth. Here, it is placed within the subfamily Oecophorinae of the concealer moth family (Oecophoridae). Alternatively it has been placed in the Elachistidae or Depressariinae together with its presumed closest relatives.
Pseudatemelia flavifrontella is a species of gelechioid moths.
The Depressariinae – sometimes spelled "Depressiinae" in error – are a subfamily of moths in the superfamily Gelechioidea. Like their relatives therein, their exact relationships are not yet very well resolved. It has been considered part of family Elachistidae sensu lato or included in an expanded Oecophoridae. In modern classifications they are treated as the distinct gelechioid family Depressariidae.
Depressaria is a genus of moths in the superfamily Gelechioidea. It is the type genus of subfamily Depressariinae, which is often – particularly in older treatments – considered a distinct family Depressariidae or included in the Elachistidae, but actually seems to belong in the Oecophoridae.
The Oecophorinae are the nominate subfamily of moths in the concealer moth family (Oecophoridae). They are part of the insufficiently studied superfamily Gelechioidea, and like their relatives, the circumscription of this taxon is disputed.
Alabonia is a genus of gelechioid moths. Here, it is placed within the subfamily Oecophorinae of the concealer moth family (Oecophoridae). Alternatively it has been placed in the Elachistidae or Depressariinae together with its presumed closest relatives. It has also been proposed to separate Alabonia and closely related genera as a subfamily Enicostominae, but this has generally not been followed by recent authors regardless of where they placed the present genus.
Crassa is a genus of the concealer moth family (Oecophoridae). Among these, it belongs to subfamily Oecophorinae. The genus name Tichonia, established by J. Hübner in 1825, was frequently misapplied to these moths by earlier authors. But as the type species of Hübner's genus is the greenweed flat-body moth – originally described as Tinea atomella, but nowadays called Agonopterix atomella –, Tichonia is actually a junior synonym of Agonopterix. That genus does belong to the same superfamily as Crassa, but is placed in the concealer moth subfamily Depressariinae which is sometimes treated as distinct family.
The Amphisbatinae was a small subfamily of moths in the superfamily Gelechioidea. Like their relatives therein, their exact relationships are not yet very well resolved. The present lineage is often included in the Depressariinae as a tribe Amphisbatini, though more often within the context of a "splitting" approach to Gelechioidea systematics and taxonomy, wherein the Depressariinae are elevated to full family rank and the Amphisbatinae are treated as a subfamily therein. An even more extremely split-up layout even treats the Amphisbatinae as full family Amphisbatidae. In the scheme used here, the Amphisbatinae are included in the Oecophoridae as a subfamily alongside the Depressariinae.
Pseudatemelia is a genus of gelechioid moths.
Denisia is a genus of the concealer moth family (Oecophoridae). Among these, it belongs to subfamily Oecophorinae. It was originally established as a subgenus of Borkhausenia.
Paratemelia is a genus of gelechioid moths. In the systematic layout used here, it is placed in the subfamily Amphisbatinae of the concealer moth family (Oecophoridae). Delimitation of Amphisbatinae versus the close relatives Depressariinae and Oecophorinae is a major problem of Gelechioidea taxonomy and systematics, and some authors separate the former two as full-blown families, and/or include the Amphisbatinae in Depressariinae, or merge them in the Oecophorinae outright.
Agonopterix is a moth genus of the superfamily Gelechioidea. It is placed in the family Depressariidae, which was often – particularly in older treatments – considered a subfamily of the Oecophoridae or included in the Elachistidae.
Luquetia is a moth genus of the superfamily Gelechioidea described by Patrice J.A. Leraut in 1991. It is mostly placed in the family Depressariidae, which is often – particularly in older treatments – considered a subfamily of the Oecophoridae or included in the Elachistidae.
Exaeretia is a moth genus of the superfamily Gelechioidea. It is placed in the family Depressariidae, which is often – particularly in older treatments – considered a subfamily of Oecophoridae or included in the Elachistidae.
Anchinia is a genus of gelechioid moths.
Hypercallia is a genus of gelechioid moths.
Alabonia staintoniella is a species of gelechioid moth. Here, it is placed within the subfamily Oecophorinae of the concealer moth family (Oecophoridae). Alternatively it has been placed in the Elachistidae or Depressariinae together with its presumed closest relatives.
