FYI, I found a reference of DNA studies that say the Amazon mollies are
probably descended from either p. velifera or, more probably p. latippina,
and a probably now extinct parent species.

I think the amazon molly is similar, in that it is an entirely female
species which breeds with male Sailfin or Shortfin mollies. It is thought
that the species is the result of hybridization between the Sailfin and
Shortfin mollies.
