Re: Can you help me identify this ciliate?
Could it be Frontonia with a fagocited long cyanobacteria filament occupying its periphery?
Take a look at the Ehrenberg's original image of Frontonia leuca at http://www.infusoria.org/?page_id=401

Es muy parecida también a
Chlamydodon sp.

Re: Can you help me identify this ciliate?
It is not Chlamydodon (a marine ciliate). That genus has a distinctive "traintrack" around the perimeter of the cell, but it is colorless, whereas this is green. Also, if you look closely, you'll see that it is a coiled strand of cyanobacteria, with a free end poking out at the lower right side (another short segment of cyanobacteria is visible in the middle). Chlamydodon would also have an oral basket, in the central anterior of the cell. Pau is right, this is almost certainly a species of Frontonia. We don't see the mouth, unfortunately, but the cell is surrounded by trichocysts and has a slightly acuminate posterior (despite being distorted by the long strand of cyanobacteria it has ingested).
