Perhaps it might be of some use.
In most cases HW spot 2 is slightly or partially dislocated from spot 3.
In A. phaenops it seem to be nearly more so.
It may be a useful point of exclusion ID ie. if HW spot 2 is only partially or dislocated halfway from spot 3, it can not be A. phaenops.
TL Seow: Cheers.
