Relevant Information:

Body brown to blackish; pale midlateral stripe present but may not always be distinct; pale stripe along dorsal mid-line (not always distinct). Head and body rugose, covered by relatively large tubercles, usually distinct with naked eye, of very heterogeneous sizes. Anal usually without black mark restricted to base. Glyptothorax is distinguished from all other sisorid genera by having an adhesive apparatus on the thorax with with grooves parallel or oblique to the longitudinal axis of the body (vs. thoracic adhesive grooves transverse to the longitudinal axis of the body in Pseudecheneis, and thoracic adhesive apparatus absent in all other genera). Remarks: G. interspinalum has been assessed as Near Threatened with an inferred population decline of 20-29% in the past ten years, as a result of heavy pollution in the Red River.
