countless hours of searching and i cant find a single pic of a Nahangbagrus songamensis....
from the info I've managed to acquire, it looks as if this fish lives in the northern side of vietnam in a river called Song Gam. if any experts have any info or photos of the fish, please do share!

Hi Ichthusfish,

I found one article that catalogs this species, and I can find the citation for the original description, but I can't find a copy of the original description.

If you haven't seen this, I'll refer you to this article:

http://lkcnhm.nus.edu.sg/nus/pdf/PUBLICATION/Raffles Bulletin of Zoology/Supplements/Supplement 27/rbz_S27.pdf

I have no extra information, but at least now it's in the Cat e-Log: .

Cheers, Eric

I have the original description (in a three-volume work on the freshwater fishes of Vietnam), and the quality of the images in there are abysmal. That said, the photo of Nahangbagrus is not the worst in the book.
