It is stated that in P. hewitsoni male the HW outer band ( chevrons ) is dislocated completely at vein 4. Most of them significantly so.
No 3's HW band is not quite so, resembling no. 2. P. hewitsoni is quite rare in P. Malaysia probably less so in Langkawi. https://species.wikimedia.org/wiki/P...iMFUpUnAC1.jpg
