Members of the genus Psilorhynchus McClelland are small cypriniform fishes with arched backs and flattened ventral surfaces, which are common inhabitants of the streams of the Ganges-Brahmaputra drainage of Bangladesh, India, Eastern Nepal and adjacent China and the Irrawaddy drainage in northern Myanmar and southwestern Yunnan (Rainboth, 1983; Vishwanath & Manojkumar, 1995). Seven species of Psilorhynchus are recognized: P. sucatio (Hamilton, 1822), P. balitora (Hamilton, 1822), P. homaloptera Hora and Mukerji, 1935 ^ZBK, P. pseudecheneis Menon and Datta, 1964 ^ZBK, P. gracilis Rainboth, 1983 ^ZBK, P. microphthalmus Vishwanath and Manojkumar, 1995 ^ZBK and P. arunachalensis (Nebeshwar, Bagra & Das, 2007) .
