Is this yellow discoloration from spider mites?
mites?
Re: mites?
Maybe, but probably just corking. Mite damage usually starts out as a fine speckling, although eventually it can completely scar over the skin.

Re: mites?
I don't think you have a lot to worry about. I DO believe that Iann is correct that it is simply corking.
Cacti have a tendency to develop, as they get older/bigger, bark-like areas close to the ground, possibly as a defense mechanism against rot and or pests. This cork like skin is much tougher than the rest of the plants skin.
Note that this "feature" is only present on the larger of the sprouts ... buds ... uhhhh ... limbs ... uhhh, whatever.

Re: mites?
Okay thanks. I considered corking but in my experience the epidermis is not visible through the corking, i.e., the corking is not translucent. I looked at it through a magnifier and saw no mites.

Re: mites?
Corking can look different on different species. Some species are prone to developing orange patches. Take a close look at my Ferocactus, it has a similar appearance:

- This was a year ago - now it looks about the same, the plant is just bigger.
