Need ID for Poritia spp

[Commander]

Dr Seow, need your help on the IDs of these Poritia species shot in various locations in Peninsular Malaysia. Thanks!

1. Shot at Gua Tempurung, Perak

2. Shot at Fraser's Hill

3. Shot at Pulau Langkawi

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.

Thanks for your detailed analysis, Dr Seow.

Initially I thought that No 2 and 3 were the same species. Their markings appear to be quite similar other than the fact that No 2 is rather worn out. I agree that it was a female, as I managed to take a look at the upperside and it was as you've mentioned. I didn't manage to see what No 3's upperside looked like though.

I think 3 should also be a P. erycinoides male.

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.
