Glyptothorax is a genus of catfishes order Siluriformes of the family Sisoridae. It is the most species-rich and widely distributed genus in the family with new species being discovered on a regular basis. These species are distributed in the Black Sea basin, northern Turkey, south and east to the Yangtze River drainage in China and south throughout Indo-China to Java, Indonesia. They are found in Asia Minor (in the Tigris and Euphrates River drainages) and southwards to Southeast Asia. The genus is very diverse in the Indian subcontinent.Southeast Asian species tend to have restricted distributions.
This genus is easily distinguished from other sisorids by having an adhesive apparatus on the thorax with grooves parallel or oblique to the longitudinal axis of the body, as opposed to grooves transverse to the longitudinal axis of body or the thoracic adhesive apparatus entirely absent. The dorsal fin and pectoral fins have strong spines. The dorsal fin spine is smooth or serrate on the front edge and smooth or finely serrated on the posterior edge. The pectoral fin spine is serrated on the front edge. The head is small and depressed and the snout is conical. The body is elongate, from moderately to greatly depressed. The skin is either smooth or tuberculate. The eyes are small and dorsally placed. The lips are thick, fleshy and often papillate. The maxillary barbels have a well-developed membrane and a soft base. The gill openings are wide. The paired fins are plaited and modified to form an adhesive apparatus in some species of Glyptothorax.
