Synonyms and other taxonomic changes
Depressariidae Meyrick, 1883
*treated as a full family by Heikkilä et al. (2014) (1)
Note: Epigraphiidae is an older name and has priority, but is rarely used. As of 2014, Heikkilä et al. "were preparing an application to the International Commission on Zoological Nomenclature (ICZN) to suppress this name in favor of Depressariidae" (1).
Explanation of Names
Depressariidae from type genus Depressaria (Haworth), Latin meaning "flat," for their flat bodies. (2)
Numbers
2300 spp. worldwide (Heikkilä et al. 2013)
Identification
"The genital feature present in many depressariids (though not all), and in Elachistidae, is a spinose, lobe-like gnathos in the male genitalia (also in Coleophoridae). The pupal characters include the presence of lateral condyles on the abdominal segments, preventing lateral movement of the pupa, and a paired spur group, often on swellings that may be developed as so called pupal legs, ventrally on abdominal segment 9" (1).
Remarks
Previously treated as a subfamily of Gelechiidae
