I have decided to dig in my pictures and see if I have any pics of Glyptothorax I had in the past. Found some...
1) were sold as G. siamensis
2) and 3) Were sold as G. sinensis
4) I don't remember under what name I bought them (as I recall G. siamensis)
I would appreciate opinions on what species they are. Unfortunately I would not be able to do additional pics since all of these are gone long time ago.
Thanks,
DM

It's a lot easier to identify these if you have a picture of the belly (and the thoracic adhesive apparatus).

Unfortunately I have the ventral picture of the first fish only.

This looks like the belly of fish 3 rather than fish 1.

I have double checked - ventral picture is that of the Glyptothorax on the first photo for sure.

Using the latest (unpublished) version of Sundaic Glyptothorax taxonomy:

1: G. schmidti
2: G. sinensis
3: G. sinensis
4: G. fuscus

Identifications are not 100% certain without being able to see the thoracic adhesive apparatus.

Huge thanks, Silurus!!!
