Erethistes is a genus of catfishes (order Siluriformes) of the family Erethistidae. With the inclusion of the synonyms Hara and Laguvia, this genus includes seven species, E. filamentosus, E. hara, E. horai, E. jerdoni, E. maesotensis, E. pusillus, and E. serratus.[1]


This genus is distributed in the Ganges and Brahmaputra drainages in northern India and Nepal, and east and south to the Salween drainage on the border of Myanmar and Thailand.[1] E. filamentosus is from the Irrawaddy, Sittang, and Salween drainages, Myanmar as well as from the Rangoon River drainage in Myanmar. E. hara inhabits the Ganges, Brahmaputra, and Irrawaddy drainages, northeast India, Bangladesh, Nepal, and Myanmar. E. horai originates from the Brahmaputra drainage, northeast India. E. jerdoni is found in the Ganges and Brahmaputra drainages, northeast India and Bangladesh. E. pusillus inhabits the Ganges and Brahmaputra drainages of Northeast India. H. serratus originates from the Barak and Jiri Rivers of the Brahmaputra drainage, Manipur, India.[1] E. maesotensis is known from Moei River, a tributary of the Salween River near Mae Sot on the Thai-Burmese border.[2]


Erethistes species lack a thoracic adhesive apparatus, a smooth to granulate anterior margin on a strong dorsal fin spine, a papillate upper lip, and 8–12 anal fin rays. The pectoral fin spine is serrated anteriorly and posteriorly. The anterior margin of the pectoral fin spine either has serrations all pointing toward tip of spine; arranged in divergent pairs; or outwardly directed and not divergent. The head is large and broad with a conical snout. The body is robust rather than slender as in some other erethistid genera, and is moderately short and flattened. All barbels are annulated with black rings.[1]

Species range from in length from about 2–13 centimetres (.8–5 in) SL.[3][4][5][6][7]


E. maesotensis has been observed to inhabit fast-moving waters; during the rainy season, the water depth can increase by at least 3 metres (10 ft). The substrate mainly consists of small stones and sand with numerous empty gastropod shells.[2]

E. pusillus occurs mainly in hill streams. This species is found in muddy parts of rivers overgrown with vegetation.[4] E. horai is found in rivers and streams.[6] E. hara is found in slow-moving rivers and streams.[5]
