A. tigrinum, or a. mavortium???

[orion]

hello,
i thought that all a. tigrinum subspecies, except for a. tigrinum tigrinum, have been re-classified as subspecies of a. mavortium, formerly a. tigrinum mavortium. i am a little confused because all websites, except amphibiaWeb, and most written materials still refer to a. tigrinum and subspecies as the common tiger salamander, and most still list a. mavortium as a subspecies of a. tigrinum. does anybody know the current classification of a. tigrinum and a. mavortium, and where to find references?
thanks,
orion

The current classification is:
A. tigrinum tigrinum
A. mavortium mavortium
A. mavortium diaboli
A. mavortium melanostictum
A. mavortium nebulosum
A. mavortium stebbinsi

The major papers where this is explained are:

Ambystoma mavortium---Shaffer and McKnight, 1996, Evolution, 50: 430.
