Hi Dr Seow,

Thanks for the detailed explanations. Just wanted to check in on the Ganda Dart cos it looks to me like there's a darkened vein on the underside. Or perhaps I'm focusing on the wrong detail... ;P

Apologies for the poor photo though.

The features are not absolute . There are a lot of variation in each species.
One dark vein does not matter.
Most examples of P. ganda have a bit of dark dusting of the veins but not to the extent seen in P. omaha

Typical P. omaha male Upperside & underside.
