Thought you would find it interesting that the Shampupa pleco was looked at by some Dutch researchers last year. They concluded it to be its own species, and to temporarily designate it as the L418 until they can classify it. Anyways, looks like you have at least one. I can't really tell on the second one. I picked one up in November 2008 and researched to death trying to figure out what the heck these plecos were. Interesting though that some have patterns and some don't. Who knows if they will be further broken down into different species.
