A very large salamander with a stout body, broad head, and small eyes. It is covered with yellow to olive spots or blotches irregularly scattered over the back and sides.
Formerly included as a subspecies of A. tigrinum known as A. t. velasci, it is now generally recognized to be an independent species.
