There are four people that I know of that can probably answer your query. Ian Fuller in the U.K. (who I believe invented the first cory), knows more than anyone I can think of. His website CorydorasWorld.com is a must have for cory lovers, and Mr. Fuller is a gem.
Here in the States there are three folks that I would highly recommend. Frank Falcone of Laurel Lake Guppies (coryologist on AquaBid) in N.J., Eric Bodrock of All Odd Ball Pets (also on AquaBid) in Pittsburgh and Steve (Red Kahuna on AquaBid) here in Baltimore. Between them, if there's a cory that they haven't bred I doubt that it's been discovered yet.
All great guys who have forgotten more about corys than most of us will ever know. I don't believe that any of the previous suggestions were correct. I breed most of those varieties myself and don't recognize yours.
