Depressariidae
The first attempt to assign micro moths with vernacular names called these Flat-bodies. I think it's fair to say that wasn't overwhelmingly popular, but I'm not sure the latest version, variably assiging most of them Buffs or Browns is entirely satisfactory either. Flatwings would have worked for me...
Lots more to follow in due course...
