Species

There are currently four recognized species in this genus:[1]^[2]^[3]

Glyptosternon akhtari Silas, 1952
Glyptosternon maculatum (Regan, 1905)
Glyptosternon malaisei Rendahl & Vestergren, 1941
Glyptosternon reticulatum McClelland, 1842 (Turkestan catfish)

Some authorities recognize another:

Glyptosternon oschanini Herzenstein, 1889 (Oshanin catfish) but this is considered a synonym of Glyptosternon reticulatum by FishBase.

Distribution

Glyptosternon species are distributed in

Burma.^[4] 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. reticulatum is from the Indus drainage including Afghanistan, Pakistan, Kashmir, and western China.^[4] G. oschanini is known from the Upper Syr Darya and probably Amu Darya in Kyrgyzstan, Uzbekistan and Tajikistan ^[2]

Description

Exostoma is distinguished by having the combination of an interrupted groove behind the lip (post-labial groove), the

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.^[4]

G. maculatum and G. reticulatum grow to between 24.0–25.5 centimetres (9.4–10.0 inches).[5]^[6]

Glyptosternon malaisei was known only from the type, which is from the Irrawaddy drainage in Burma. A recently published study reidentifies G. malaisei as a species of Glaridoglanis, on the basis of the spatulate, homodont dentition on both jaws and the premaxillary tooth patch not extending posterolaterally; and considers it to be a junior subjective synonym of Glaridoglanis andersonii.^[3]

Ecology

G. maculatum is found in mountain rapids.^[5] G. reticulatum is found in rivers and streams under stones and rocks. It feeds mainly on invertebrates, especially insect larvae.^[6]
