That's called "microevolution" and nobody disputes it.

This is why I say that an arbitrary distinction is not a barrier. Unlike most of your anti-E brethren, you have moved the micro-macro distinction up the Linnaean ladder to the level of order. You have to evolve out of the order Caudata to macroevolve for medved. (I assume here that going from salamander to mudpuppy or siren would not fill the bill for you. "Salamander" is a rather unscientific term which applies across several families in this order.)
But even a Linnaean order is an arbitrary distinction, the kind of thing people argue over. What is the real-world barrier?
That's like looking at humans, chimps, gorillas and bonobos [sp?] and saying, 'they all still look like primates.'
