With regards to dark dusting on the hindwing veins, I would only take it as a serious feature in the freshest of specimens. In too many worn individuals, the dark-dusting turns out to be just evidence of wear. That's another reason why I've only been photographing these fresh individuals.
Thanks for pulling those images of the Pahang T. augias. Telicota and Potanthus, while possible to identify from clear field shots, showing both sides of pristine individuals, definitely require more rigour in examining them. The fact is that for a long time, many butterfly enthusiasts in Singapore have been content with IDs prescribed with incomplete information (eg. ventral only). I still have a few questions and I'll take these up with you over PM.
I appreciate that we are making the effort to scrutinise the details and I'm once again grateful to learn from the knowledge shared here.
I'll leave the ID's as they are in post 75 for now.
