Leg asymmetry
Reminds me of a lobster that lost a claw and is growing it back. Some (most?) spiders can regrow lost legs when they molt but the new leg may not be as big as the old.

In this case, he's still miss
In this case, he's still missing leg I; leg II is simply positioned more forward to compensate for the loss. Being already mature, I don't think he'll grow the first leg back, as a moult is necessary.

Or... (it just occurs to me)
Or... (it just occurs to me) he lost both leg I and leg II on the right side and only leg I has regenerated (much smaller than the original).

[No, I think I do see the coxa of leg I -- so probably the first scenario is correct.]

I agree
I think I can see the coxa for leg I too.
