Biology

Dorsal spines: 1; Dorsal soft rays: 6; Anal soft rays: 12 - 14; Vertebrae: 36 - 37. Differs from all other species of the genus Glyptothorax, except for Glyptothorax siamensis, by the possession of a blackish brown body with indistinct pale longitudinal stripes on the lateral line and mid-dorsal regions. Can be differentiated from Glyptothorax siamensis in having a smaller eye with eye diameter 6.3-7.2% HL and a thoracic adhesive apparatus with less convex lateral edges and absence of anastomosing striae. Distinguished from other congeners by the following characters: caudal peduncle length 18.6-21.0% SL; caudal peduncle depth 7.9-9.4% SL; vertebrae 36-37; tubercles on the dorsal surface of the head with a single, median ridge; pale markings on the nuchal pale absent; length of adipose-fin base 12.3-14.5% SL.
