As I have already pointed out (twice), the weevil genus Mimus was renamed
Marvaldiella in 1999 (last century!) , details here:
when GBIF (or CoL) says that a name is accepted, I expect that to actually mean

Do you mean why didn't we include the word "provisionally" for the weevil on
that web page? Firstly, I told you I was going to be looking into more detail
tomorrow (mine, not yours - its still Sunday night here - albeit 22:56).
Second, provisional or not, this would not have impacted the explanation I
provided before. The COL asserts there is a genus Mimus in the weevils and
grouped several species in it. This is valuable information regardless of the
taxonomic status especially if even taxonomists are publishing species names, or
specimens, or weevils with this genus. Sure, we could edit out the
provisional taxa from COL and not include them in our derived taxonomic
structure and have been only left with Mimus the bird. What would that have
Our only 'authority' indicates there are two Mimus. We retained it as part of
the structure we use to organise data because it said so. That is why.
Perhaps a better understanding of what provisional means and why are there two
animal Mimus in the COL in the first place is what I need.
