I think that could be Leptophrys elegans, but maybe also Penardia mutabilis
I never seen one

Carlos, Ferry is going to love this one. Heck, I love it and I don't know what it is. Did you look on his amoeba pages for a match? Can't wait to hear what it is.

So is Mitch. The more similar are Leptophrys elegans or Penardia mutabilis, but this is the first time that i see

There, I've taken the data
I want to know what thinks Ferry

I had a nice holiday in Peru and took some very interesting samples there. But now I'm back home again and ready to look at your problem.
Actually, it is also a problematic creature for me

It is filled with whirling granules, but the filopodia are not granulated. Between the base of the filopods web- or veil-like cytoplasm is visible. In the first session it looks like a Vampyrella, but these group is supposed to suck algae cells. Your amoeba is filled with e.g. diatoms, which is not a vampyrellid characteristic. The second session shows an elongated form, which looks more like a Leptophrys. Penardia mutabilis is quite different, it has very granutaled filopodia and is usually filled with green material, the same is true for Chlamydomyxa.
I'm not fully convinced it is a Leptophrys, but for the moment I don't have another option.
Here is some information:http://www.jstor.org/stable/2455309?seq=2

Thank you Ferry.
Congratulations for your travel to Peru
I will write 'Probable Leptophrys'.
It is the one that I have found more similar between the hundreds of photos that I have observed.
But my experience is much very little.
A greeting
