Gabriella is the name she is referred to in some of the movies I found:
Trans Anal Brazil 1 (Concorde) (blue dress & white lingerie)
Trans Anal Brazil 2 (Concorde) (black short skirt)
Trans Anal Brazil 3 (Concorde) (as a nun) AKA Cream Queens (She-Male Fantasies presents)
Brazilian Transsexuals - Trans Sex (Book and Film International)
She Males From Rio (Heatwave Raw/Metropolis) (Compilation from Trans Anal Brazil-movies)

Could this be Gabriella Bionda, a former São Paulo-escort who is no longer active?
