DR011 Rupela tinctella (female?)

Crambidae - Wingspan: 32mm.

A problem species, which I have not been able to confirm. I have come across this and the other DR011 moth in a number of Neotropical countries, and it has been difficult to identify, but I have come across this ID on a French Antilles web-site which looks more likely. Two forms of moth came into our trap which superficially look similar here, and I wonder whether the smaller examples are actually the males (shown under the same DR number), whilst this larger form, looks to be very similar but also has a yellow tail tuft. Perhaps this is the Female?
