The photos are not very good, and only show a limited view. For example, it would be good to have a veiw of the lower mandible from below.
In my opinion, features that fit Pale-legged are:
1. Pale leg, 2. short primary projection.
Features that do not fit Pale-legged are:
1. The wing bars are too thick.
2. Time of occurrance. What is the previous latest record for Pale-legged?
Things that are uncertain to me.
1. Whether the tertials have a clear pale edge.
2. The color of the lower mandible from below.
There is good chance that this is Pale-legged, but I don't think I can make a definite conclusion here.
