looks like the Surface constructor also needs a bit depth for it to work.
what you want is Surface(size, SRCALPHA, 32). this should do the job...

>>> s = 1, 1
>>> [hex(m) for m in Surface(s, SRCALPHA).get_masks()]
['0xff0000', '0xff00', '0xff', '0x0']

>>> [hex(m) for m in Surface(s, SRCALPHA, 32).get_masks()]
['0xff0000', '0xff00', '0xff', '0xff000000']

>>> [hex(m) for m in Surface((1,1), SRCALPHA, 16).get_masks()]
['0xf00', '0xf0', '0xf', '0xf000']
