It is only known from the drainage basin of the Kapuas River, Borneo.This species can be readily distinguished from most other Glyptothorax species of the region by its slender body. The only possible confusion is with Glyptothorax platypogonides (as which this species was originally misidentified) and Glyptothorax siamensis but G.
