IUCN Red List

Glyptothorax granulus has been recorded from two localities that are quite apart in feeder streams to main rivers, about 200 km aerial distance. It is also expected to be distributed in between these two localities as also in the drainage in Myanmar. Although the range is inferred to be less than 20,000 km2 it is not very rare and is not threatened throughout its range. It is therefore assessed as Least Concern, but needs updating, (IUCN 2010).
