@treichard I am not aware about formal moving of Dafa back to Epicallima. However, in all European sources that I know, including recent ones, the species is listed under Epicallima. See, eg.,
or
Z. Tokár, A. Lvovsky & P. Huemer, Die Oecophoridae Mitteleuropas, Slamka, 2005.
Since the vast majority of the observations here are from Europe, I have decided to make this swap.
I do not know what was Hodges' reasoning for the split. Could you please give a reference?
Hodges described Dafa in his Oecophoridae fascicle 6.2 in the Moths of North America series. It is available for free at http://www.wedgefoundation.org/publications_paypal.asp .
Most recent European literature I can find puts formosella in Epicallima. So your taxon change looks correct. I just haven't found the particular article that argues for formosella to be moved to Epicallima.
I bring up these questions because recently the North American moth folks have noticed that Hodges argued in his same work that Epicallima is an invalid replacement name for Callima, and so they are moving the Epicallima species back to Callima. I am looking into updating iNat's taxonomy, but I am less familiar with the literature beyond North America. The two questions I am looking into are: (1) E. formosella's genus should change, but should it change to Dafa or Callima? (2) Is there any reason any of the other Epicallima species should not be changed to Callima? The taxon flag about this is at https://www.inaturalist.org/flags/533014 .
@treichard Thanks.
I am not sure which treatment is the most correct, and what should be the fate of other (Epi)callima species. I am not an expert in this group. Unfortunately, as often happens, the treatment of Hodges, seemingly reasonable, omits the Palaearctic part of the group.
@kharkovbut Yes, a good point. Most of the Epicallima species are not in North America, yet Hodges split just 3 species into 2 genera.
Do you know if any specialists who work on Eurasian Oecophoridae or Epicallima itself are active on iNaturalist?
@treichard I do not know, but suspect there are none.
@kharkovbut Hodges described genus Dafa for this species in 1974. Is there any subsequent literature that moved formosella back to Epicallima? Lepiforum's species page does not cite any literature after 1942 (http://www.lepiforum.de/lepiwiki.pl?Epicallima_Formosella).
