In the male genitalia, the uncus with its bifid chaetae is single or bicapitate (in Loxostegopsis and Tatobotys) or entirely split (in Metasia).

A recurrent character in several but not all species of this group is the fovea in the male forewing at the distal end of the discal cell.

In Southeast Asia, the larvae of the Duponchelia group are detritivores in marshes and intertidal environments of mangrove swamps.

[2][4] Particular food records are known for only a few species: The genera Anageshna, Apogeshna, Loxostegopsis, Penestola and Steniodes are confined to the Americas, whereas Bradina and Dolicharthria can be found in both the Old and New World.

The remaining genera are Old World taxa, with Epherema, Hymenoptychis, Symmoracma and Tatobotys primarily found in the tropics of Asia.
