Glyptosternon is a genus of sisorid catfishes native to Asia.
There are currently four recognized species in this genus:
Glyptosternon species are distributed in Indus drainage in Afghanistan, Pakistan, India (in the state of Jammu and Kashmir), Uzbekistan, Tajikistan, Kyrgyzstan and western China, east to the Irrawaddy drainage in Burma.G. akharti is from the Bamian River of the Oxus Watershed of the Indus drainage in Afghanistan. G. maculatum is found in the Brahmaputra drainage of India and China. G. malaisei, known only from the type, is from the Irrawaddy drainage in Burma. G. reticulatum is from the Indus drainage including Afghanistan, Pakistan, Kashmir, Uzbekistan, Tajikistan and western China.
Exostoma is distinguished by having the combination of an interrupted groove behind the lip (post-labial groove), the gill openings extending onto the underside (venter), homodont dentition with pointed teeth in both jaws, a crescent-shaped tooth patch in the upper jaw, and 10–12 branched pectoral rays. The head is depressed with a broadly rounded snout. The body is elongate and flattened ventrally to the pelvic fins. The eyes are minute, dorsally located, and under the skin (subcutaenous). The lips are thick, fleshy, and papillated. The teeth in both jaws are pointed and the tooth patches in the upper jaw are joined, forming a band produced posteriorly at sides (crescent-shaped). The paired fins are plaited to form an adhesive apparatus.
