Poritia is extremely difficult since the ID is based largely on the upperside patterns.

However no. 2 is easily identifiable as the female P. erycinoides phraatica by the oblique orange band.

No. 1 is also recognisable as a typical male P. erycinoides , the FW white band is narrow, crooked, & the series of chevrons forming its outer boundary dislocated strongly (with a gap) at vein 4.

No. 3 is rather difficult.
It could merely be a form of male P. erycinoides .
The white band is broad & the chevrons on its outer boundary merely dislocated.
This plus the fact it is shot in Langkawi suggest it is a male P. hewitsoni.

Others are darker.
